We run location APIs. Geocoding, routing, store locator, address autocomplete, etc. at enterprise scale. When a checkout page resolves your address, or a courier finds you first try: that's us.
Stack: Python, Go, Rust, TypeScript, Valkey, Postgres, OpenSearch, Docker, AWS, Datadog.
We are a small team, owning and driving complex solutions to production on a daily basis. We are looking for a good generalist to become an expert in a part of our stack. 1st PR ships to prod within a week, very little process and good team spirit!
The mission We’re building a best-in-class multi-modal AI agent product (voice + SMS + email) with the potential to disrupt deeply entrenched software businesses and unify a fragmented industry. We’re a tiny team with real traction pre-product, moving fast, and we care obsessively about craft.
Why this role This is a founding engineering seat: you’ll be an early builder shaping the product, architecture, and quality bar from day one. In the first 3–6 months, the role is highly IC-focused. As we scale (including our first in-person hub/site and new hires), this role has optionality (i.e., growing into a leadership role or staying on the IC track and owning the engineering roadmap) for the right person.
What you’ll do
Build real-time systems for voice (streaming audio, low latency, turn-taking), SMS, and email automation with robust state + memory. Design the foundation: architecture, data model, reliability, observability, deployment, and developer velocity. Set the quality bar: clean code, pragmatic abstractions, testing strategy, “don’t break prod,” and thoughtful product UX. Partner closely with the co-founders on product decisions. You’ll have real influence over what we build and how it feels + how it's designed.
What we’re looking for You should be able to work anywhere in the stack (frontend, backend, infra, integrations) and you know how to make smart tradeoffs.
Strong product sense: you’re obsessive about confusing UI and you want to make workflows feel magical. Systems thinking: you can design for latency, reliability, and iteration speed (especially for real-time voice + agent state). High ownership: you run toward ambiguity, unblock yourself, and care deeply about outcomes. Startup mindset: high-risk/high-reward energy, low ego, high pace.
Bonus points:
Experience with agentic systems: LLM orchestration, tool calling, RAG, evals, prompt/versioning, guardrails. Voice/telephony or streaming experience (WebSockets/WebRTC, audio pipelines, turn detection). Messaging + deliverability experience (SMS workflows, email sending, compliance/opt-in, bounce handling). Familiarity with modern stacks (examples): TypeScript/Node, Python, React/Next.js, Postgres, Redis, queues, Docker, AWS/GCP, observability.
I'm Julien — I lead Product Engineering at Oaktree. My background is tech, not finance: startups, Meta, data infrastructure companies.
I'm hands-on and building a flat, small team that operates like an engineering org, not a bank IT department. If you come from a tech background, this post is for you.
We're building the next-generation platform for Oaktree's credit business (private credit included) — one of the largest and most complex investment strategies at a firm managing $220B+ in assets.
This is a newly formed Product Engineering group, and we're modernizing everything: practices, architecture, tooling, culture.
In the past month alone we've stood up a new CI/CD system, evolved the architecture, and gone from release cycles measured in months to hours. We're shipping rapidly and the pace is accelerating.
The work: data-intensive applications across the full stack of a credit investment platform — ingestion, transformation, analytics, and the tools that put insights into the hands of investment professionals. No traditional PMs — you work directly with business stakeholders, own priorities, and ship.
This is a hands-on, code-every-day role.
What we're looking for: - 10+ years building and owning data-intensive systems in production
-Strong CS fundamentals (data structures, distributed systems, concurrency, performance)
- Deep expertise in data modeling, pipeline architecture, and systems that process/transform/serve large volumes of data
- Python + at least one statically typed/compiled language (C#/.NET, C++, Java, Scala, Go)
- Cloud-native experience (our environment is Azure, but what matters is you've operated at scale)
- Comfortable with ambiguity, direct stakeholder engagement, and owning outcomes end-to-end
- Genuine interest in applying generative AI practically across engineering and product workflows
A note on title: the internal title is Vice President, which is standard in finance.

We're doing to government software what challenger banks did to banking. We build critical systems for scientists and researchers, making sure public money is well invested.
Our work involves high-performance Python for petabyte-scale Earth Observation and satellite datasets, clean web UIs for complex data, and modern DevOps pipelines to automate scientific workflows.
Small team, fast-moving. Trust and autonomy from day one. No bureaucracy, just hard problems and impact.
We're hiring mid and senior Python Developers with 3+ years of experience.
Send your CV and a couple of paragraphs on why you're interested to careers@oxidian.com with the role in the subject line.
HME Technologies (https://hmetech.com/) is a small, profitable media and affiliate marketing company. We build audiences, sell sponsorships, and run a growing portfolio of content properties across YouTube and emerging platforms. We're operator-run, AI-native, and looking for our first AI Operations Lead to work directly with the co-founder to turn our AI capabilities into a serious operational advantage.
What you will do:
> Build the short-form engine: Design and run an AI-leveraged workflow to repurpose years of long-form content into 50-100 pieces/week for TikTok, Reels, and Shorts.
> Stand up owned analytics: Move us off spreadsheets and partner dashboards. Build clear tracking for email growth, content performance, and affiliate attribution.
> Be the AI execution engine: Build automations (Make, Zapier, n8n) and write Python or JavaScript when needed to glue systems together.
> Operationalize AI internally: Build practical AI workflows for our creative directors, salespeople, and content producers to speed up their output.
What we are looking for:
- You ship: You aren't just "AI-curious"—you use Claude, ChatGPT, and automation tools to do real work every week.
- You operate: You can take a directive like "we need a thing that does X" and come back with a finished system, making the small decisions along the way.
- You write: We work async. We use Slack, Notion, and Google Docs. If your default is to schedule a meeting, this is the wrong role.
Our culture: Async-first, zero bureaucracy, and a sustainable pace. We don't do crunch culture, we respect off-hours, and we completely pause work for Shabbat (Friday sundown to Saturday night). Sustained operators need sustained rest.

We run a worker wellbeing and compliance platform used by global buyers and their supply chain sites across Asia. We're in the middle of a meaningful migration and platform buildout — you'd be joining at a point where architectural decisions matter and your fingerprints will be on the system for years.
*The work:* Our stack is Django + Python on the backend, dbt for data transformation, React/Next.js on web, and Expo/React Native for mobile. We run on AWS and Azure. Right now we're migrating legacy services while simultaneously shipping new features — so you'll need to be comfortable holding both in your head.
*What we're looking for:*
- Strong Python/Django chops — you've built and maintained production APIs, not just tutorials - Comfortable with React/Next.js; bonus if you've touched Expo or React Native - You understand what a data pipeline actually does (dbt experience a plus, but SQL fluency matters more) - Cloud experience on AWS or Azure — not ops, but enough to not be blocked - You care about code quality without being precious about it
*What this isn't:* This isn't a greenfield startup with infinite runway. It's a real product with real users, real technical debt, and a migration in progress. If that sounds like a problem, this role isn't for you. If that sounds like the most interesting kind of work, let's talk.

We're a seed stage (VC backend) company building a vertically integrated design and manufacturing platform for precision mechanical parts. We are developing our own CAD/CAM software running on top of our own manufacturing facility. The team has previously developed CAD kernels, design software, and autonomous robotic manipulators, and comes from Amazon Robotics, Siemens, nTop, and Vicarious Surgical.
Most design and manufacturing software companies treat the factory as a black box and optimize geometry in isolation. Our bet is that the only way to really bring software and ML into design and manufacturing is to own the full process ourselves. The platform you'd help build includes: customer-facing design software, the ML engine that turns CAD files into machine instructions (G-code), the simulation layer, and the shop floor operations themselves.
We are looking for someone independently driven who wants to operate like a founder. You'd own architecture, help shape the company's vision, and build a product from the ground up. If you've worked on cloud infrastructure, distributed systems, CAD/CAM software dev, geometry kernels, robotic perception, motion control, or spent time on a shop floor, we'd like to talk. We are open to sponsoring visas for the right candidate.
Roles:
Founding Computational Geometry Engineer: Hybrid B-rep + SDF kernel work. STEP AP242 ingestion, B-rep surgery, feature recognition, and the geometry layer underneath our DFM and CAM pipelines. If you've worked on Parasolid, OCCT, nTop, or shipped anything that touches BRep diff, parametric replay, or differentiable geometry, we want to talk. C++ and Python.
Founding Full-Stack Engineer: Someone who can take ownership of the reliability, automation, and evolution of our core systems that tie into our CAD/CAM software, internal shop-floor systems. You’ll work across the stack, with a strong emphasis on backend, infrastructure, and system-level engineering, to strengthen the foundations that everything else runs on. This role is for someone who enjoys digging into complex systems, building the architecture and tooling to keep them running reliably (including the frontend).

We're hiring continuously for the positions below— they aren't singular positions that will close once filled. Our philosophy on hiring is that the candidate is more important than the position. For each new member of the team, we design a custom role and responsibilities that are specialized to their interests. Other companies will come up with a long list of specific requirements for a position with the expectation that you'll exactly replace someone from the team, or that you'll be the perfect tetris piece that satisfies the job requirements decided by a committee. MixRank is more pragmatic: we'll first get excited about having a unique individual on the team, then we'll figure out the best way to accommodate their specific talents.

Tables power every financial model, clinical trial, and scientific experiment, but deep learning has mostly ignored them. No natural sequence, no spatial structure, no shared vocabulary across datasets. LLM architectures don't transfer. We built TabPFN, the first foundation model that actually understands tabular data (published in Nature, 3M+ downloads, new SOTA for tabular ML). The hardest problems are still open.
The model is half the product. The other half - training infrastructure, real-time serving, developer platform, reliability - is what turns a research breakthrough into something enterprises trust in production. We're hiring across both.
ML Engineer, Cloud Platform — Design and scale the core infrastructure for serving and finetuning foundation models in production. Early enough that you're making the architecture decisions, not inheriting them.
ML Engineer, Training Infrastructure — Own GPU infrastructure, distributed training performance, and the developer productivity layer (CI, experiment tracking, model registry) that keeps research moving fast.
Full Stack Engineer, ML Platform — Build the product that puts tabular foundation models in users' hands, from data upload through inference and results. You'll work across frontend, backend, and directly with the research team to turn new model capabilities into production features.
Research Engineer, Foundation Model — Design experiments, run ablations, build training infrastructure, contribute to papers. Research engineers here aren't supporting scientists — they are the science team.
Also hiring: Research Scientist, Applied Scientist, Forward Deployed ML Engineer, Developer Relations Engineer, AE, BDR.
20-person team selected from thousands applicants. Backgrounds from Jane Street, Google, CERN, G-Research. Led by Frank Hutter, advised by Yann LeCun and Bernhard Schölkopf. €9M pre-seed from Balderton, with backing from leaders at Hugging Face, DeepMind, and Black Forest Labs. Comp competitive with top AI labs, meaningful equity.
All roles: https://jobs.priorlabs.ai

I’m the founder and CEO, and I’m trying to do what I call “enlightened business”. I take responsibility for both staff and clients, and I look for people who approach their work with a similar sense of ownership.
Applicants must meet a high bar - I personally review every hire. In return you’ll get:
* Flexibility and a low-bureaucracy environment * Clients that won’t treat the vendor like “the B Team” * The chance to act as a code architect, not just implement tickets * Exposure to a wide variety of industries and modern challenges * Me as your personal champion and advocate Feel free to submit, even if you already did in the past.We’re currently especially seeking:
Back-end, Front-end, and Full-Stack Software Engineers, Tiers 3 and 4 (Typescript/Javascript, React, NextJS; Ruby on Rails; Python; DevOps, and third-party API integrations)
Our Tier 3 ("mid-tier") roles are typically 5-10 years experience with $150-$180K total annual comp.
Our Tier 4 ("senior") roles are 11-20 years experience, $215-$260K total annual comp.
(Higher tiers exist, and we always welcome exceptional applications.)
Though not yet universal, many of our clients are now demanding senior/staff engineers with success using modern agentic approaches. Be ready to explain where current models work well and where they do not.

COVU is an AI-first insurtech startup rebuilding the 20-year-old legacy infrastructure of the $365B+ insurance distribution industry.
We recently announced our $16M funding round (bringing our total to ~$50M) and launched COVU OS. We aren't just slapping an "AI wrapper" onto old software; we built a task-native orchestration layer from scratch. COVU OS converts messy, unstructured insurance workflows (emails, PDFs, manual triage) into defined tasks, dynamically routing them to the right execution layer—whether that's an AI agent, a licensed human professional, or an offshore team.
We are a scrappy, execution-focused team of builders. We heavily encourage using AI tools (Cursor, Copilot, Gemini) in your daily workflow to ship code faster. If you hate spending months in "discovery" and prefer to just build and own production systems end-to-end, you will fit right in.
The Stack:
Data: Snowflake, dbt, Airflow, Python
Product: TypeScript, React, Node.js / Python backends, Cloud Infrastructure
Open Roles:
Staff Full Stack Engineer (Technical Lead): You will be a foundational technical leader shaping the architecture of COVU OS. Expect deep, architecture-level design work paired with heavy, hands-on IC contributions.
Sr. Full Stack Engineer: You will own complex product surfaces end-to-end, building out the agentic orchestration layer, user interfaces, and enterprise API integrations.
Data Engineer(Remote): You'll be the primary builder of our "Golden Policy Journal," transforming highly complex, messy carrier data into our single source of truth using Snowflake, dbt, and Airflow.
Sr. Product Manager (COVU OS): You will own the roadmap for our core operating system. We need a highly technical PM who can dive into the weeds of agentic workflows and write specs that engineers actually want to read.
To apply for any of these roles, visit: https://www.covu.com/careers
Full time engineering role (Remote, US person required; Pacific time zone)
Stack: C#, Python, Gemini API on Windows, lots of legacy systems/constrained enterprise environment. Health systems experience preferred. Understanding of cost effective, reliable LLM API use. Should be flexible: do PM-like work with less-technical client domain experts, solve problems end to end, willing to data cleaning and detailed work for client goals and security/compliance gruntwork, even when it's not technically elegant. Self motivated, willing to understand legacy and undocumented codebases, but also willing to take instructions.
Ideal candidate has real (pre-Claude Code) experience, but is ready to do fast iteration in post-AI world, while actually reading what the AI does. We're ok if your stack is different, if you're both technically mature and up to date on modern fast-turnaround AI-based development. Probably in the 5+ year experience range.
REMOTE anywhere, project based or initially part time: startup generalist hacker, maintain systems and websites, code one-off prototypes. Should be good enough to code without an AI in a few languages, but an effective AI harness coder. Can do a small but complete app/project end to end, including basic marketing. 2+ year exp or a new grad with a good portfolio or major project; happy to consider more experienced person. Good role for someone who's working on their own startup to pick up some side money and experience. Projects could be anything from game-like apps/novelties to voice tools to utility apps.
REMOTE anywhere, project based or initially part time: help on some more experimental mathy projects. M.S./Ph.D. in statistics, physics or related, with pragmatic programming experience. Possible projects: gaussian process modeling; designing evaluation metrics; compression; Bayesian tools for radiology imaging. May be good for a grad student part time. This is the fun stuff the founder would rather be doing himself if he had the time.
REMOTE (US person) Half-time remote admin/chief of staff type: deal with bookkeeping, compliance, communications, social media, phone calls - save us time on everything non-technical. Should be effective AI user; should have some relevant experience supporting tech business.

Kanary is a personal security platform that monitors the web to identify and reduce risk based on an individual's threat model. An executive has different exposure than a gamer, and our system classifies each person's risk across 55,000+ sources. We've been building since 2020, started in campaign security, data science, and government agencies, backed by Mozilla and Y Combinator. We have 200+ organizations on the platform and are fully funded by our customers.
Attackers have never had better tools. LLMs, social media, and search surface personal data in new ways. A few prompts can launch a deepfake and impersonation campaign. Risk sources appear and disappear across social platforms, telegram chats, and private data broker platforms. Kanary exists to play the cat and mouse game for people at the speed and scale of an agentic internet.
Kanary is a combination of software workflows (crawling, scraping, automation), AI (data classification, research, code generation), and people (analysts trained to support customers and escalate). This is dynamic system and requires an interest in adversarial programming.
We’re growing our team, and seeking a multifaceted engineer (2+ years experience). Our software stack is python, javascript, react, and for LLMs, we use Anthropic, OpenAI, and experiment with model fine tuning as needed. Experience with web scraping, data pipelines, or security tooling is required.
Email steven@kanary.com with something you've built and why it was hard.

We're hiring an AI Engineer to build and ship production AI systems - not research prototypes. Startup experience is a must: we want someone who has shipped fast in a small team, owned systems end-to-end, and is comfortable with ambiguity. Big-company-only resumes won't be a fit.
You will own: - RAG pipelines and agentic workflows (end-to-end accuracy) - GPU-optimized model deployment (Trident-style architecture) - Production MLOps: distillation, fine-tuning, training orchestration - Data modeling for AI persona capabilities - The infra around it: Docker, CI/CD, logging, monitoring, observability
You should have: - 3-12 years shipping AI/ML in production (notebooks do not count) - Time at a startup or scale-up where you owned what you built - Strong Python; bonus for C++/Java/C# in performance-critical paths - Hands-on with RAG, MLOps tooling, and GPU deployment at scale
W2 full-time. Must be authorized to work in the US. No remote, no C2C.
Apply: saikumar@engineeringsquare.us (subject: "AI Engineer - [Your Name]")
We are building the trust stack for AI code generation, targeted at high-stakes computing where wrong numbers cost real money: a statically typed functional language designed for coding models, a compiler whose guarantees double as audit-grade trust infrastructure, and a coding model fine-tuned on the language with compiler fitness as the training signal. Language and model are co-designed.
Small team out of PyTorch, FAIR, and Meta. Strong institutional VC support from our pre-seed; active investor interest heading into seed.
Founding Research Scientist: own the agenda across the language and the model. Type system design, compiler analyses that produce useful fitness gradients, and fine-tuning open-weight coding models on a language with no pretraining footprint. Publish in PL and ML venues. Strongest fits cross between machine learning, programming languages, and formal methods. PhD preferred, equivalent output equally fine. Stack is Rust, Lean 4, Python.
Founding Engineering Lead: own engineering across compiler internals, language runtime, GPU backends, notebook and library tooling, and the AI infrastructure around training, evaluation, model release, and likely public inference. We already support x86 and ARM, CUDA and AMD, macOS and Linux, and the matrix grows. Real feel for statically typed functional programming expected; the kind of engineer who picks up Lean or Haskell on a weekend because they wanted to. Have led engineering before, formally or not. Stack is mostly Rust with Python where it earns its place, primarily on AWS.
Both roles: comfortable with early-stage ambiguity, define your own roadmap, defend it with evidence.
