Succeed is building a platform to help high-school students discover academic opportunities around the world — summer schools, competitions, research programmes, and university experiences that many students never hear about.
Our goal is simple: reach one million students and open doors that are currently invisible to most of them.
We’re hiring a lead engineer to take technical ownership of the platform as it moves from MVP to market. You’ll work directly with the founders and product designer and own the system end-to-end: product features, automations, infrastructure, and integrations.
We believe modern AI tools dramatically change how small teams build software. Tools like Claude and Claude Code are part of the workflow here.
This role is ideal for a strong early-career engineer or recent graduate who enjoys building real systems, learning quickly, and taking responsibility for a live product.
Stack includes Supabase, PostgreSQL, n8n, APIs and webhooks.

Return (https://return.energy) is hiring a software engineer who will work on platforms that accelerate the transition to carbon-free energy. Return’s main activity is building and operating industrial-size Battery Energy Storage Systems. Our operations are located in the Netherlands, Germany, Belgium, and Spain. You will be making a measurable (country-level) impact on the transition to renewable energy. Return recently raised €300M to support its growth.
While we employ over 100 people, Return’s technical team is still small (15 people). Our platform automates processes in energy storage, monitoring, market optimization, sales, project management, procurement, construction, and customer service.
During the first three years of operation, we laid the foundation for our platforms, and we are ready to scale up. This is why we are looking for an experienced software engineer.
You will be working on internal tools that support our business departments (origination, development, construction, operation, and general). Our tech stack is straightforward: Postgres, Ruby on Rails 8, Turbo, Stimulus, and Tailwind. We tend to keep meetings to a minimum in order to provide at least five hours of uninterrupted coding time per day. We practice code reviews and apply automated and manual testing. The platform is often deployed multiple times per day.
We’re very much open to remote work as long as you live in the EU. Our hiring process is swift but thorough: a 30-minute call to get acquainted and discuss financials, one or more technical interviews, and a paid visit to Amsterdam to meet the team.
The tech team members have co-founded several companies and have experience with remote development teams since 2008. They will personally help you through most of the recruiting process (there is no recruiter involved).

Hightouch is building an AI platform for marketing and growth teams. It’s not just about the LLM hype though!
1) You’ll get to work with a sharp team and we won’t waste your time in interviews - across three interviews we assess based on systems design conversations and a manager chat, no leetcode
2) Real marketing teams at companies you’ve heard of have used our agentic products to plan, design, and ship campaigns in days, instead of the usual weeks/months
3) The foundation that we’ve built over the past 5 years - building on top of data warehouses like Snowflake and Databricks, and solving some complex distributed systems and real-time streaming systems problems on top - give us an edge over legacy players who require complex data integrations
4) We’re doing great in the market - we doubled our ARR over the last year and plan to do it again

I built a small AI healthcare SaaS that recently reached six-figure ARR with enterprise customers. The product works and has real users, but I’m now focused on another startup and no longer have time to actively run it.
Much of the business is already automated (billing, onboarding, and parts of support), but there is significant room to improve systems, growth channels, and product experience.

Own the full stack for real: BGP/EVPN, transit, data center hardware, one of the world's largest Mac build fleets, and a private cloud spanning multiple locations — not just wiring up AWS components. Hybrid Linux/macOS environment, heavy Terraform/Ansible, usage. If blinking LEDs and routing tables get you going, this is the rare infra role where you can touch everything end-to-end.
We’re building an AI system that will disrupt the SaaS market as a whole. The foundation already exists and is running.
The concept itself is not difficult for experts once it becomes public, but the architecture and timing are key. We’re moving extremely fast.
Plan:
- release an open-source core - build a large community around it - scale fast enough to push competitors out
Current state is first friendly test customers onboarding in a few days. This is just 1 week old.
We’re currently reaching out to major AI labs since they could profit a lot from this, but we don’t need them to scale aggressively.
Right now there’s no significant funding yet, but the pace is extremely high and this could gain traction very quickly. We can likely raise ~€250k fairly quickly via public funding in my country, without giving up shares, but first we want to assemble the right people and make a plan together.
Looking for:
- someone with founder experience / VC contacts, or - hardcore AI engineers like me who ship extremely fast
We are currently EU-based, but the company can be set up wherever makes most sense for the business. It's huge fun to work with it.

Description: Careforce AI is building autonomous AI agents that eliminate the manual administrative burden in healthcare (fax machines, scheduling, calling). We find, call, and schedule patients, breaking interoperability barriers that have plagued the industry for 40 years. We are a well-funded, YC-backed company with massive customer demand.
We are looking for a Senior Fullstack Engineer to be a foundational member of our small, ambitious team. You will have significant ownership working across the stack to build and scale the core of our AI agent platform. We are looking for builders with 5+ years of experience, preferably with an early-stage startup background (Pre-seed to Series A).
Decise is a hands-on advisory and delivery firm that helps organizations unlock the full value of their technology and improve business profitability.
We work directly with executives to define what should be built, then we build it. Our work spans software engineering, data platforms, analytics, and customer-facing digital products. We often operate as fractional CIOs and CTOs, guiding both the strategic direction and the technical execution of our clients’ technology initiatives.
Our clients rely on us to turn complex business problems into working systems — not slide decks.
We are intentionally small and senior. Everyone on the team is a builder who can operate independently, solve complex problems, and deliver finished systems that people actually use.
White-glove service. Blue-collar grit.
We’re looking for a principal-level technologist who can move between engineering, architecture, and client strategy. Most of your time will be spent building systems and writing production code. The rest will involve working directly with executives to shape technical direction and ensure the work creates real business value.
Typical technologies we work with include React, Angular, Next.js, Node.js, Go, Snowflake, SQL, dbt, Domo, Streamlit, AWS, Vercel, and modern AI-assisted engineering tools. The exact stack varies by client; the ability to learn quickly and move confidently across technologies matters more than any specific tool.
Strong candidates typically have 10–15 years of experience building production systems and are comfortable operating both as hands-on engineers and as technical advisors to executives.
This is a long-term, full-time independent contractor engagement (1099). Everyone at Decise — including the founders — operates in this structure. Compensation is designed to be competitive with senior engineering roles at leading technology companies.
The fastest way to stand out is to show us something you’ve built: a production system, GitHub repository, application, or data platform you designed.

Here's the problem: A small drone flies at you at 60mph / 100 km/h You have a camera, one edge processor, and must detect, classify, and track it at 30fps — against sky, trees, buildings. Starting from 100+ meters. If your pipeline drops a single frame at far range, the intercept fails. Sounds impossible? We think together we can solve this.
Now the second problem: Your guidance law needs to predict where that target will be in 0.5 seconds, compute the intercept geometry, and command the flight controller — with noisy IMU data, wind gusts, and a target that doesn't fly in straight lines. No GPS. No RF link. Just onboard compute.
We solved the guidance part in simulation. Our IBVS pipeline tracks and hits moving targets in SITL. The hardware prototype is built and ready. But the real engineering starts now.
We need:
* Computer Vision & Edge AI Engineer — YOLO on Jetson/Hailo/QRB5165. Detect, classify and track small targets at 100m+. Model pruning, TensorRT, sensor fusion. If you've pushed edge hardware to its absolute limits, this is your problem.
* GNC / Flight Systems Engineer — Image base visual servoing, proportional navigation, EKF/UKF state estimation, PX4 integration. Take what works in sim and make it survive real-world sensor noise.
* Simulation & Test Engineer — SITL/HITL, Monte Carlo campaigns, digital twins. 10,000 simulated engagements before anything leaves the ground.
* Technical Advisors — Drone warfare, GNC/aerospace, defense procurement. A few hours/month from the right person changes our trajectory.
We're a pre-seed defense startup in Munich building autonomous interceptor drones to stop FPV kamikaze drones. 2 founders. Salary + equity. No AI screening — we read every application.
Trunk is an a16z funded (25M) Series A dev tools startup, redefining software development at scale. At Trunk, our mission is to help teams create high-quality software quickly. AI has made writing code 10x faster, but shipping is still painfully slow. The bottleneck has shifted downstream - to merge conflicts, flaky tests, inconsistent code quality, and dozens of other frictions that drain productivity and morale. Engineering teams that can stay focused on designing, implementing, and delivering software will build magical, high-quality projects - and they'll be happier doing it. We're building a CI Reliability Platform that empowers teams to land code faster and develop happier!
Our products:
* Merge Queue: Ensure your PRs keep the builds you care about green at any scale. *Flaky Tests: Detect and eliminate Flaky Tests. Our tech stack:Frontend: Typescript, React, Next.js, AWS Backend: Typescript, Node, AWS Data pipelines: Dagster, Python, polars CI/CD: GitHub Actions
Unlimited PTO (and we all actually take PTO), competitive salary and equity packages! Please apply here: https://trunk.io/jobs.

We build real-time civilian threat intelligence for conflict zones. Multi-model AI pipeline (Gemini 3 Pro / Flash) ingests OSINT from verified sources, runs it through a gated verification system, and pushes geolocated alerts to offline-first mobile clients. Think of it as a personal intelligence analyst for non-combatants — on a phone that works on 2G.
This is not a pitch deck. We have a working system (v1.0.34): backend is live, Flutter apps are approved on both App Store and Play Store, multi-gate AI pipeline is processing real OSINT, admin console has human-in-the-loop verification for high-severity alerts, and we just made our first hire. 73 candidates vetted, 1 accepted (Senior AI/Backend Engineer — now owns the AI verification pipeline). Pre-seed is imminent with multiple NGO grant applications under review (WFP, IRC Airbel, DRK Foundation).
*We need one person:*
*Systems Architect / Founding Backend Engineer* You will own the Django backend, MongoDB document schemas, and infrastructure that everything else runs on top of. Our AI pipeline lead handles the Gemini orchestration — you own the data layer, the API surface, the deployment pipeline, and the system design that makes it all reliable at scale. A bug in this system isn't a 500 error — it's a missed warning in a conflict zone.
Must have: Python/Django (production), MongoDB, system design thinking. Strong plus: DevOps (Docker, AWS), LLM integration, Flutter, OSINT, geospatial.
We also welcome strong full-stack implementation engineers who ship fast and want founding-team equity. Same stack.
*Compensation (No BS):*
- Now: Sweat equity (12-18% SA / 5-10% FSD, 4yr vest, 1yr cliff). This is founding-team ownership. - Pre-Seed (closing): $3,000/month + equity. - Seed (6-12 months): 75% market salary + equity. Increases from there.
If you need full salary today, this is not for you. If you want to build something where the stakes are real and you're willing to bet on yourself to get there — we should talk.
*Stack:* Python 3.9+, Django 4.1.13, MongoDB, Flutter, Vertex AI (Gemini 3 Pro / 2.5 Flash / 3 Flash Preview), Docker, AWS.
*Apply:* PeterJFrancoIII@gmail.com — Resume or GitHub + what you'd build in your first week.

Innolitics builds AI/ML software for medical devices — the kind that detects ear infections, tracks metastatic cancer, and plans radiation therapy. 60+ FDA clearances. We need engineers who want their work to matter. We're a remote-only firm (since 2012) that does engineering, regulatory, and cybersecurity under one roof. Our team includes MDs, PhDs, and software engineers. Clients range from Series A startups to large device companies. We're hiring for three roles:
1. Physician-Scientist (MD/PhD) — Biostatistics & AI Software Development MD + PhD in biostatistics, bioinformatics, epidemiology, or a related quantitative field. You'll design biostatistical plans for AI validation studies (MRMC, standalone, prospective), build production-grade statistical software and data pipelines, write FDA-facing statistical sections, and analyze large clinical imaging datasets. Fluent in Python and/or R. This is not a pure research role — you'll ship code that gets FDA-cleared and deployed in clinics.
2. Senior Web/Mobile Medical Device Engineer 5+ years SWE experience. 3+ years each in web and mobile. Fluent in TypeScript and Python. You'll build medical device software and produce FDA-facing technical documentation. Cross-functional role bridging engineering and regulatory teams.
3. Medical Device Software Engineer 3+ years SWE experience. Fluent in Python, C++, or TypeScript. Heavier emphasis on software development initially; you'll grow into regulatory documentation work over time. All roles involve writing production code for medical devices, authoring documentation for FDA submissions, and working directly with clients. No prior medical device experience required — we'll teach you. Why engineers stay here:
Agentic AI tools (Claude Code, etc.) are part of our workflow. We treat them as a impact multiplier, not a threat. ~1 hour of meetings/week for ICs. Flexible hours. 2 hours every Wednesday dedicated to learning ("10x Time"). Healthcare-only revenue. No debt. Never had a layoff. We pay $300 for take-home exercises because your time has value.
Stack: Python, TypeScript, C++, R, Django, React, TensorFlow, PyTorch, scikit-learn, Qt, Terraform.
Apply: https://innolitics.com/careers/
How we work (we publish our handbook): https://innolitics.com/about/handbook/
Animators (2D/3D or hybrid—experience with AI tools a plus)
Junior Software Developers (Python, Node, JS, or open to learning new tech)
Interns (all backgrounds, generalists, tech, or creative)
We are also looking for writers (different kind of hacking)
Important: You must be a parent (of any age child) We want people who care deeply about kids and learning. Lived experience as a parent is essential—our mission is to build things real families want.
Why join us?
Fully remote, async-friendly Ship real things that impact how kids learn Fast, creative, zero-corporate-BS environment
Direct access to founders; real ownership
Opportunity to shape our tools and shows from the ground up
To apply: Email jobs [at] studyturtle.com with your background, a few sentences about why edtech is important to you, and why this mission excites you. Please include links to any relevant work.
We are the hiring company and will reply to all genuine applicants. No recruiters, no agencies, please.

At FusionAuth, our mission is to make authentication and authorization simple and secure for every developer building web and mobile applications. We want devs to stop worrying about auth and focus on building something awesome. We also recently acquired a fine-grained authorization company ( https://fusionauth.io/blog/fusionauth-acquires-permify ) and are going to be building in that area as well.
There are a lot of companies in the auth space, but we feel like we have something special:
* a unique deployment model (self-host on-prem or in your cloud or run in our cloud)
* A well designed API first approach; one customer compared our APIs to petrichor
* a mature product (the code base is nine+ years old and we've found and fixed a lot of the sharp edges around core login use cases; but don't worry, there are plenty more features to add)
* our CTO is the founder and still writes code
* a full featured free-as-in-beer version which makes the sales cycle easier; prospects often come in having prototyped an integration already
Our core software is commercial. We open source much of our supporting infrastructure. Technologies and standards that you will work with: modern Java, PostgreSQL, Docker, Kubernetes, MySQL, OAuth, SAML, OIDC.

Empire Flippers is a true global-remote company with travel in our DNA and employees scattered across 5 continents and all sorts of countries. Since I joined 6 years ago, I've personally been to India, the US, Brazil, Ecuador, Colombia, Mexico, the Philippines, China, Japan, Thailand, the UAE, all while working remotely and coding our Ruby on Rails + React app. More about us here: https://empireflippers.com/about-us
Though not as well known in the Hacker News / venture-backed startups sphere, Empire Flippers is widely considered the #1 marketplace for buying and selling online businesses in the 5 to 8 figure USD range.
Think of businesses like --- that recipe site you landed on as the first result when you googled "best chicken tikka masala recipe". Or the Amazon FBA seller whose product you purchased when shopping for "Widget XYZ" (with Amazon FBA, these ecommerce businesses never touch inventory and so it's a fully online business).
Turns out these type of businesses may be earning 10s of thousands of dollars per month in profit (or more!) and when the (often first time) founder is ready to sell, Empire Flippers is the #1 place to do it safely, securely and at a fair market price.
Before I joined Empire Flippers I only had a peripheral understanding of this space, but now that I've been steeped in this industry I can say that this "mini M&A" world is just as exciting as the high-flying unicorns (and decacorns) that we read about daily on Hacker News.
The company is hiring for a few different positions (both technical & non-technical), all of which can be found here: https://empireflippers.com/careers
But in particular, I'm hiring a Ruby on Rails developer to help me continue to build out new features in our Platform, both for customers and to help run our (very extensive) internal operations of vetting incoming businesses, facilitating their sale, and migrating them to the new owner after they've been purchased.
That job ad can be found here: https://empireflippers.com/career/ruby-on-rails-developer/
As mentioned, we are a global-remote company that hires people of all nationalities located in any country in the world.
Hope to see your application soon, and with any questions feel free to email me (Ben) at beng at empireflippers.com
