I'm building an art tech startup, and I am seeking a highly driven full-stack technical co-founder ideally located in NYC. You should ideally have a proven track record of launching and operating tech products that successfully generated sales or a substantial user base in the US or Western Europe.
I am a finance, strategy and tech professional with experience co-founding a dating website that secured paying users in its first month of launch. I handled all non-technical work, including go-to-market, partnerships, strategy, UI/UX design, and marketing. Professionally, I've advised tech executives and founders at early-stage to global enterprises. I know how to build and scale tech products from 0 to 1.

Company: We're a small scientific software development company that develops custom scientific and engineering analysis applications in domains including: space situational awareness (monitoring the locations, health and status of on-orbit satellites), image simulation, high power microwave systems, modeling and simulation, laser systems modeling, AI/ML including physics-informed neural networks (PINN), human body thermoregulation, computer vision and image processing, high performance computing (HPC), computer aided design (CAD), and more. All exciting applications and no CRUD. We emphasize high quality code and lightweight processes that free software engineers to be productive.
Experience: Except for interns, we currently require a Bachelors degree in physics, engineering, math, computer science, or a related field. Masters or PhD is a plus. (Roughly 25% of our staff have PhDs.)
Technologies: Lots of C++23, Qt 6.9, CMake, git, OpenGL, CUDA, Boost, Jenkins. Windows and Linux, msvc/gcc/clang/clangcl. AI/ML and analysis projects use Python and C++. Web projects use Java and Typescript/React.

For those who know what they're doing - even without AI. Our focus is agentic engineering: building and improving systems, workflows, and engineering practices around AI agents and AI-assisted development. We use AI tools heavily, but we expect engineers to know when they help, when they hurt, and how to keep generated code out of the debt spiral.
This is a hands-on role for someone who cares about maintainability, testing, refactoring, deployment safety, and engineering judgment under pressure. You should be able to improve systems yourself, help other engineers work effectively with AI, and raise the bar across teams.
You’ll likely fit if DORA metrics are useful to you, not decorative; if you know why small commits matter; if you’ve seen what a good deployment pipeline does to a team; and if you can use AI to scale quality, not just output.
Apply at jobs@techtalk.at. No cover letter. Instead, tell us about a system you improved with AI, and what your contribution actually was. Find out more: https://techtalk.at/job-offers/principal-software-engineer-a...
I'm Russ, one of the founders of 9 Mothers. We're making AI weapon systems out of Austin, TX. Our first product is for stopping group 1 suicide drones. We started in 2025 - still a small team under 20 people. We're hiring for a lot of roles, but mostly in software and robotics.
We're a software engineering consultancy that builds enterprise software the right way. We negotiate the right to open source all our client code, maintain a handful of popular libraries, and our engineers contribute to Django core. We sponsor PyCon, DjangoCon, and Django Girls because we're invested in the ecosystem we build on.
We're looking for software engineers who value software design, system architecture, and collaboration. You should be comfortable with about half of these areas and eager to learn the rest: web application security, relational database design (PostgreSQL, beyond "SELECT *..."), Django internals, React, and distributed systems. What you'll actually work on: complex state machines for financial workflows, multi-tenant architectures with row-level security, custom database functions when the ORM isn't enough, and React frontends that handle real-time data without being a mess of useEffect hooks.
We're a small team where you'll own features end-to-end (database design to React components) and have opportunities to shape technical decisions. You'll get paid to write open-source code with a team that practices empathy and values work-life balance. If you've ever wished your job involved more elegant state machines and fewer marketing landing pages, let's talk: info@fusionbox.com.
At Formical, we believe we can become the first sustainable generation on Earth. Biotechnology plays a key role in this future - benefiting all people, animals, and our planet by making industrial production more sustainable. But bioprocessing still runs on fragmented data and tacit knowledge. The infrastructure to turn data into the intelligence that teams need to scale doesn't exist yet, hindering the sector’s progress. Our product accelerates bioprocessing by connecting fragmented data, enabling predictive modeling, and ultimately closing the loop between measurement and action.
We're not looking for specific skills, just willingness to learn. I joined a couple months ago with little React/TypeScript full-stack experience, but with CC I managed quite well coming from a Python backend background. Nothing's enforced though! We're a small team, have some customers, and are looking to build out the platform and the client-base significantly this year.

Stack: PHP (CodeIgniter 4), MySQL (AWS RDS), Python, Node.js. PHP is a hard requirement.
