Join to apply for the Founding Engineer (Equity + Salary) role at Affinity Labs
We’re building the future of company creation - a full-stack AI venture studio that partners with content creators to co-found authentic, scalable software businesses. By combining AI-native development with creator-led distribution, we're unlocking a new frontier where software is rapidly built and distributed through trusted digital communities.
We aim to launch ventures 10x faster and cheaper than traditional methods using our internal "AI factory": a multi-agent architecture, reusable component libraries, and a growing knowledge graph that learns from every product we ship.

Tasks
Responsibilities
1. Code with AI-first speed. Use AI to turn product specs into production-ready React, Supabase, and serverless back-ends in days, not weeks.
2. Architect for scale (and scrappiness). Apply clean, hexagonal patterns so v1 can evolve without rewrites.
3. Prototype → pilot → product. Move fast through validation loops: hack the MVP, shadow users, ship the fix, repeat.
4. Wear many helmets. One sprint you’re spinning up CI/CD; the next you’re tweaking prompts or jumping on a creator livestream to debug user feedback in real time.
5. Set the engineering culture. Establish the rituals, docs, and testing standards that future hires will learn from you.
Requirements
Requirements
* Fresh degree, fierce skills: BSc/MSc in CS, AI, Maths, or similar, graduating 2024/25.
* Software Development: You’re an expert in developing native apps, with a mobile-first mindset. You must be able to build at lightning speed without compromising quality.
* Shipping Experience: You’ve shipped AI side projects - or research - that prove you can learn fast and finish.
* AI-native developer: You already treat LLMs as teammates and using agents to automate tasks.
* Grit & ownership: When the build breaks at 11 pm, you pour coffee.
* Edge-of-curve learner: You track the latest AI tools, play with new MCPs, and deploy multi-agent systems
* Action oriented: Strong bias toward rapid execution and experimentation.
Must-haves
* React / Next.js, Supabase / Postgres, Python back-end chops
* Prompt-engineering or fine-tuning experience
Nice-to-haves
* Familiarity with Stripe, Discord, TikTok or other creator-economy tools
* Side hustle, hackathon wins, or open-source contributions
Benefits
Perks & upside
* Equity: Significant
* Salary: Competitive graduate package with rapid step-ups tied to revenue milestones (upon shipping or fundraising)
* Creator collabs: Brainstorm features with the largest creators who reach millions.
* Mentorship: Weekly 1-on-1s with our CTO and access to operator-investors across the studio network.
* Culture: Bold, confident, creative, real-no buzzword bingo
If interested in applying, please include one paragraph on the coolest thing you built with an AI tool.
More on why this is a career launchpad
* Own the code & the company. You step in as Founding Engineer #1, receiving a meaningful equity stake from day one.
* Ship faster with AI at your side. We’ve baked AI tools into our workflow so you spend time solving problems, not yak-shaving boilerplate.
* Ride a rocket, not a conveyor belt. Affinity Labs is a venture studio that partners with top content creators to turn influence into scalable software. Think “Prime for software”
* Grow like crazy. You’ll architect, build, and launch multiple products each year. The shipping reps you’ll get in 12 months here would take 3 - 4 years in a typical startup.
* Learn from builders, not bosses. You’ll work shoulder-to-shoulder with a founding team that has scaled VC-backed startups, closed multi-million-pound term sheets, and shipped products used by millions.
