Job Specifications

Python Developer | Python & FastAPI | Founding Engineer in AI Venture Studio Building Creator-Led Products

The Role

You’ll join an early-stage AI venture studio as a Founding Engineer, working directly with the CTO inside a small, elite team building and launching creator-led B2C software businesses.

This is a backend-leaning (~80% backend) role where you’ll own core systems end-to-end, from shaping APIs and data models through to shipping, monitoring, and iterating in rapid cycles. You’ll have real autonomy, meaningful responsibility, and a direct line between what you build and real users from day one.

Why Join

You’ll be joining a team of 5 reinventing how software companies are created. Instead of spending years searching for distribution, they partner with large creators (often 1M+ followers) as co-founders, building bespoke apps for highly engaged audiences. Every product launches with built-in demand, real users, and immediate feedback.

Under the hood, everything is powered by an internal AI-first “factory”: reusable components, agent-based workflows, and a growing knowledge graph that learns from every product shipped. The goal is simple: launch ventures dramatically faster and cheaper than traditional startups, without sacrificing quality.

You’ll get an intensity of ownership, shipping reps, and product exposure that would normally take years to accumulate elsewhere. This is a role for engineers who want to build, ship, and learn at full speed and who care deeply about turning ideas into real products people actually use.

What They’re Looking For

You will have mid-to-senior backend engineering experience in production environments,

and bring a high-agency mindset to your work, naturally taking responsibility, making decisions, and acting like a founder rather than waiting for direction. Clear communication skills are a must, as well as an ability to operate in ambiguity.
