This is for a team that I'm working closely with and helping grow. We're hiring for somebody with a hybrid SWE and Security background to help scale up the team.
It's currently one engineer who's got a ton on his plate, so the ideal person for this role is somebody who's interested in learning, digging in deep to fix issues (especially shipping PRs), and helping shape the future roadmap of the team. It is not an analyst role.
The role is primarily targeted at mid-career folks with a few years of experience (2+ years minimum). Those that are Senior/Staff level folks, especially those with a strong SWE background that are curious about security, are encouraged to apply if this role resonates strongly. (I personally transitioned from SWE -> ProdSec, years ago, and several other folks on the broader Security team have non-Security backgrounds too.)
Here is the role: https://scale.com/careers/4602047005
Feel free to apply there, email me with you resume (on my profile), or add me on LinkedIn[0]. I'll try my best to answer questions and reply to everybody, but sometimes there is so much inbound that it isn't possible. Thanks!
Open Roles:
Full-Stack Engineers: Work on mission-critical, rapid POCs to MVPs using TypeScript, React/Next.js, AWS Lambda, Postgres, and Neo4j. Help shape infrastructure and UI for bleeding-edge AI-powered features.
Senior AI Agents Engineers: Own modular agent architecture, RAG pipelines, and LangGraph-based systems in TypeScript/Node.js. Architect reasoning layers, agent memory, and performance tuning for intelligent learning agents.
Graph Engineer (Neo4j “guru”) – Lead graph modeling, Cypher optimization, and scaling strategies for our core knowledge graph.
Product Designers: Design intuitive UX/UI for AI-powered content creation and learning tools. Collaborate closely with engineers on fast-moving features. We're looking for Figma power users who think in systems, move quickly, and have a portfolio of clean, polished, shipped work.
Technical Product Managers: Define schemas, APIs, and workflows that bridge AI research to production. Own developer tooling, agent orchestration layers, and internal platforms like Linear/Notion. Drive clarity, velocity, and scalability across multi-agent, LLM-powered systems.

Zed is a company for developers, by developers. All 3 of our founders have spent years in the trenches writing software and still do it almost every single day. We know the only way to build the world's best code editor is by equipping every single member of the team to do the best work of their career.
We've raised $42M to support our ultimate vision, a new way to collaborate on software, where conversations about code remain connected to the code itself, instead of being tied to aging snapshots or scattered across different tools. The first step was creating a high-quality editor to serve as the user interface. Now this new investment lets us expand to tackle the next phase of our plan. We're developing a new kind of operation-based version control that incrementally tracks the evolution of your code with edit-level granularity, and we're integrating it into Zed to make collaboration, both with agents and teammates, a first-class part of the coding experience.

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.

About us: Absinthe is building the most sophisticated gamification engine for crypto-native incentive programs. Since 2022, our products have reached 50M+ visits and 2M+ active users. We’re a 10 person, well-funded team shipping fast.
The problem we’re solving: Tracking per-user activity across DeFi protocols sounds simple but is surprisingly hard. Want to know how long someone held an LP position, or which users provided liquidity for more than 30 days? That data is on-chain but can’t be efficiently queried today.
We built an indexing framework that turns protocol events into time-weighted balances and point-in-time actions. Adapters map protocol-specific semantics (Uniswap ≠ Aave ≠ Morpho) into a unified model. The engine handles state, TWAP pricing, and exporting data anywhere. With ~100 lines of adapter code, you can track user balances and contributions at a fidelity no one else supports.
Why it matters: This infrastructure underpins analytics, loyalty, and incentive programs across Web3. We see the Absinthe Adapter Library becoming the default developer layer for embedded finance.
The role: We’re hiring a Full-Stack Engineer to own features end-to-end schema design, wiring GraphQL, polished frontends, and deployment. Our stack: Next.js, Hasura, dbt, MotherDuck/DuckDB, GraphQL, and in-house Web3 indexing. See open positions here: absinthe.network/careers#open-positions
Get involved: - Explore product functionalities at: https://guides.absinthe.network
- Explore the Adapter Library docs: https://docs.absinthe.network/
- Join our Slack community to hack on adapters and connect with the team: https://join.slack.com/t/absinthecommunity/shared_invite/zt-...
Job Requirements: - Provision and manage bare metal servers
- Migrate existing infrastructure to improved setup
- Build monitoring systems for server infrastructure
- Implement backup and recovery procedures
- Create automation scripts for server and node management
- Upgrade legacy Docker containers and optimize resource usage
Required Skills: - Extensive bare metal server management experience
- Deep Linux/Unix systems administration
- Strong scripting abilities (Bash, Python)
- Proficient in Ansible for configuration management
- Knowledge of distributed systems and high availability design
- Docker experience with legacy system upgrades
- Security-focused server management approach
- Experience with data backup and recovery procedures

We all know that healthcare is broken. In large part, this is because too much quality, pricing, and access data has been hidden from view, and there are too many intermediaries creating complexity between consumers and the care they need.

Our triple aim: Improve your health, improve your financials, and make it convenient and easy.
We have built a proprietary dataset of over 12 million direct pay rates across 40,000 providers, covering all types of sites of care in the US, from hospitals, surgery centers, imaging, diagnostics, specialists, primary care, urgent care, virtual care, physical therapy, dental, and vision.

Spruce lets users control their data across the web. Instead of users logging into platforms, we believe platforms should request to access data vaults controlled by users.
The demand for trusted digital ID is accelerating as AI deepfakes begin to destroy most of the ways we use to verify identity today. How private or secure is it to hold your driver's license or passport up to a webcam to get a bank account? Was it ever private or secure? Stable diffusion can break so much of this already. Society will need trusted digital IDs, and our mission is to allow them to be controlled by individuals, with safeguards to prevent descents into surveillance states and checkpoint societies.
We are the main implementers of category-defining initiatives such as the digital ID program for the California DMV, and the verifiable digital credentials program in Utah. We are private sector participants in NIST's National Cyber Security of Excellence initiative for privacy-preserving digital ID.
Today, we are hiring highly capable engineers who care about making a real impact in improving public services, digital autonomy, and user privacy for the world. We work closely with public sector agencies, and everyone on our team has a high regard for those in the public service. We have a strong engineering culture. We are not a SaaS or AI company, and our roles are not for the faint of heart. You will be expected to work hard and learn a lot in this role.
Our engineers are incredibly ambitious. On any given day, they may write great Rust/C#/TypeScript, deal with mainframe dumps, read policy documents, respond to technical RFIs/RFPs, manage on-prem environments, implement new NFC + Bluetooth protocols in Swift/Kotlin, create CI/CD processes that enforce W3C accessibility guidelines and i18n requirements, rewrite lost specs from disassembled binaries, and design new protections for public key infrastructure. It is a team effort, and people with T-shirt shaped skills are able to collaborate and learn a ton from each other every day.
The potential impact of this work cannot be understated, and this is not the right job for you if you want to "join a cool AI startup" and make a fast exit. However, if you care about our mission, then you will have the opportunity to make meaningful outcomes for society that will make you feel proud.

We build Measurement While Drilling (MWD) equipment — and we love it. That passion helped us capture the majority of the North American oil & gas market, and now it’s fueling our geothermal innovation, building underground navigation systems for the next generation of clean energy.
We’re now looking for a Data Wrangler to help us make smarter, faster decisions with our data. This role blends data engineering and data science: wrangling quirky file formats, structuring messy datasets, and turning it all into live tools that guide company strategy. Starts part-time with the opportunity to grow into a full-time, career-defining role. What you’ll do
Partner with the CEO + stakeholders to translate business needs into pipelines, dashboards, and tools. Build ETL pipelines, write parsers for proprietary formats, and maintain relational databases (PostgreSQL, MySQL). Create interactive dashboards/apps with Dash, Streamlit, or similar (we avoid Tableau/Excel hell). Deliver insights via live web apps where data isn’t static — it’s explorable. Tech we use Python, SQL (PostgreSQL/MySQL), S3, modal.com. Bonus: React/web dev experience to shape customer-facing real-time tools. Why you’ll like it here You’ll own projects end-to-end, avoid over-engineering (no Kubernetes, no Airflow — just the right tools), and directly influence decisions. As our company and data needs grow, so does your role. If this sounds fun, email ken@erdosmiller.com with your background and what excites you about wrangling data.
PostHog helps engineers build better products by combining product analytics, feature flags, session replay, a data warehouse, CDP and many more.

Bubblehouse is a fast-growing custom loyalty platform, tripling the revenue each year. Headquartered in NYC, the entire team is fully remote and spread across the globe. We power loyalty programs for brands like American Girl and Old Spice.
We’re expanding our lean team of extremely experienced developers. Companies are switching from other platforms thanks to the customizations and flexibility that we offer, enabled by our pace and technical excellence, which we intend to keep for years to come.
We run on Golang and use custom data storage on top of local key-value stores, colocating the storage and compute on dedicated hardware servers, and reading data directly from mmap’ed pages of the database. Ever came across HN saying that one can run Twitter on a single machine these days? We’re doing that in production.
Zero lines of React, almost zero third-party dependencies (carefully vetted), every line of JavaScript manually written with respect and understanding of the web platform. We render HTML server-side like it’s 2005.
Looking for:
1. Top to bottom understanding of the software stack, from the modern-ish web platform to CPU caches.
2. Thinking and problem solving outside the box. (We don’t _always_ go for unconventional solutions, but we do it often enough to require a person who can do justice considering the entire problem space at every step.)
3. Demonstrated ability and hunger to learn new things quickly. (Every month we’re doing things we have never done before.)
4. Broad experience across multiple programming paradigms, platforms and software stacks.
5. Demonstrated care for the software craftsmanship (which can take many forms).
6. Great spoken English, and ability to communicate 9am to noon in New York time zone.
We give you a literally fast-paced environment (with features delivered in days) where you need to solve very challenging problems with practical advanced technology, take on entrenched market leaders, and help entrepreneurs across small and large businesses delight their fans.
Send a plain text cover letter to andrey+hiring@bubblehouse.com. Help us see how you stand out. Summarize your experience. Link to 1–5 impressive things you’ve built and proud of, link to where we can see some of your code, include your portfolio/CV, describe the platforms and stacks you’re an expert in. How did you start programming? What are you most passionate about in technology? What are the most interesting or weird things you’ve done? What are your strongest held professional opinions? Please make your email easy to read, we’ll appreciate that.
(If you have applied before, no need to re-apply, we’ll reach out.)

Oils is our upgrade path from bash to a better language and runtime.
We’ve been awarded a 4th grant from https://nlnet.nl, and our focus is to show that OSH can be the ONLY shell on a Unix system, which is hard
It looks like we will reach this goal! Other than me, there are 4 people working PART TIME on this, and we can use more help.
If you like hunting down difficult bugs, and are skilled at Unix and Python, this could be a good fit.
Most bugs are too hard for 1 person to fix by themselves, so communication is important. And writing good test cases is important.
We’re also paying people to do polished writing, since we'd like to spread the word
Starting from 131, we’re down to 41 disagreements between OSH and sh/ash/bash, when building ~1600 packages in Alpine Linux
https://op.oils.pub/aports-build/published.html
Anyone who's not “scared” of these bugs is probably a good fit, and you can do as much or as little as you like. This is also an opportunity to get deeper into the interpreter
Communication happens on Zulip, and we also have video meetings approximately every 2 weeks
I'll have a blog post explaining this work soon, but feel free to e-mail me if this (unusual) job matches your interests. Any questions are very welcome, and you can dip your toes in to see if it works for you
I wrote this page a few years ago to help people assess the fit: https://github.com/oils-for-unix/oils/wiki/Where-Contributor...
The job is remote-only, and we slightly prefer non-US contributors due to our funding
Tech stack: Python, Shell, perhaps C++

Phrasing is a language learning app built by a polyglot, for polyglots. It was designed to be language agnostic, and currently fully supports over 80 languages. It brings a beautiful, simple, and addictive [1] learning experience to languages big and small, and helps users learn 2-10x more in the same amount of time [2].
The tech stack is a ClojureScript PWA on the front end, and an Elixir umbrella application on the backend. The data processing happens in Broadway pipelines, and are horizontally scalable with FLAME. All of the data is stored in Postgres, and most of the communication between the client and server happens with a custom local-second sync engine à la Linear.app.
The company is bootstrapped and bespoke. There’s no investors, there’s no AI generated code, no shadcdn UIs. I miss the days of the early internet, and acutely feel the mass enshittification of the web. I’m really trying to do something different with the experience as well as the business, all in hopes to bring back a little bit of that wonder that was so prevalent in the days of the early internet.
The app is all working, the experience is great, and the onboarding was just finished. I’ve been using the app now to successfully learn 18 languages [3] and it’s truly a joy to use. Just finishing up the new site [4] after feedback from our last launch and getting ready for more launches [5]. The new video has been getting some pretty rave reviews and is a good gentle introduction to the app [6]
For me, this app is a dream app. This tech stack is a dream tech stack. This company is a dream company. It’s hard to believe I’m the only one these would all be true for.
I’m looking for someone who believes in the product, mission [6], and tech to come in and help me turn this functioning application into something truly great. No experience is required — just a dedication for your craft, and the willingness to take a chance in something you believe in.
If you feel that this post was written for you, please write me a well written personalized CV to hn at phrasing dot app. Low effort applications will not receive a response regardless of your CV.

Your code will run the gates at zoos and theme parks across Germany and the USA. When families scan tickets, when capacity limits kick in based on visitors and available resources (staff, equipment, facilities), when dynamic pricing adjusts for weather - that's our Rails app making real-time decisions for thousands of visitors daily.
We're 5 engineers at ToucanTix (sister company Combase has 80+). You'd have serious ownership and architectural influence from day one.
Technical challenges that actually matter:
Multi-tenant architecture supporting 100+ venues with wildly different business logic. Offline-first POS that syncs flawlessly. Complex pricing rules (weather + season + capacity + customer type) that need to stay performant. Hardware integrations with access control and payment systems.
Stack: Rails 7+ API with GraphQL (graphql-ruby), PostgreSQL doing serious heavy lifting with multi-tenant architecture, Redis for speed-critical stuff, SvelteKit frontend (if you're full-stack curious), Google Cloud infrastructure (Cloudtasker, Cloud Storage), RSpec/Capybara keeping everything bulletproof
You: 5+ years Rails. Strong at PostgreSQL optimization. Have architected systems for performance and scale. Comfortable owning technical decisions.
Us: Real ownership. No layers of management. Async-first remote culture. Profitable company, not burning VC cash. Your work has physical impact - people literally can't enter the attraction if your code breaks.
