Company Description

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 pioneering a new model of monetization by to rapidly build, launch, and scale digital ventures aligned with creators and their audiences.

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.

Role Description

This is a full-time on-site role for a Founding Engineer, located in the London Area, United Kingdom. The Founding Engineer will be responsible for leading the technical development of new software products, collaborating closely with content creators and their management teams, and implementing AI-driven solutions. The role also involves hands-on coding, system architecture design, and ensuring scalability and reliability of the software. The Founding Engineer will work in a fast-paced, dynamic environment and contribute to the overall strategy and growth of digital ventures.

Responsibilities

Code with AI-first speed. Use AI to turn product specs into production-ready React, Supabase, and serverless back-ends in days, not weeks.
Architect for scale (and scrappiness). Apply clean, hexagonal patterns so v1 can evolve without rewrites.
Prototype → pilot → product. Move fast through validation loops: hack the MVP, shadow users, ship the fix, repeat.
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.
Set the engineering culture. Establish the rituals, docs, and testing standards that future hires will learn from you.

Requirements

Full stack developer
AI-native developer that has used or experimented with the latest AI development tooling
Strong coding and software development skills in languages and with tools such as ReactNative / Flutter / Next.js, Supabase / Postgres, Python
Experience in system architecture design and implementation
Knowledge of AI technologies and machine learning algorithms. You track the latest AI tools, play with new MCPs, and deploy multi-agent systems
Experience in startup environments and rapid product development
Bachelor's or Master's degree in Computer Science, Engineering, or related field
Action oriented with strong bias toward rapid execution and experimentation.

Nice to Have's

Prompt-engineering or fine-tuning experience
Familiarity with Stripe, Discord, TikTok or other creator-economy tools
Side hustle, hackathon wins, or open-source contributions
Shipping Experience: You’ve shipped AI side projects, or research, that prove you can learn fast and finish.

Why this role 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.
