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.

Product Engineer (Fullstack) London, Old Street, Onsite, AI Agents, Skippr AI (direct, no agency please) ⭐ About the role We’re looking for a Product Engineer to join our small but high-calibre team in Old St. We’re a team that’s 100% AI-native — not just building AI agents, but using them daily to supercharge our own workflows. Our mission is to reinvent product development through specialised AI agents. We started with product design agents, and now we’re building something entirely new and multimodal — we’re pushing the limits of what agents can do. Skippr is backed by top VCs, like Bessemer (Anthropic, Perplexity, Shopify), and executives from Fiverr, Meta, Google, Lyft and more. 🏗️ What you’ll do • Modern stack: Build scalable systems using FastAPI, React, Supabase or similar modern technologies — we care more about your ability to ship quality code than specific stack experience. Own everything from database design to AI agent orchestration., • Agent Experience (AX): Shape intuitive interfaces for human–agent collaboration. Rapidly prototype and iterate with engineers and designers to discover the right interaction models for working productively with agents., • LLM Agentic Workflows: Build a system of agents — tool use, memory, retries, context updates, feedback loops, and MCP integration., • System Design & Technical Strategy: Partner directly with founders to define the technical path that balances moving fast now with scaling to many customers and dev tools later. ✅ This role is for you if • You’re a full-stack 0→1 builder who has shipped to production — ideally rapidly shipping apps and building scalable systems in containerised environments., • You’ve been a founder or founding engineer. You know what it means to build something from scratch that real people actually use or pay for., • You thrive in ambiguity. You can juggle shifting priorities, decide when to let small fires burn, and when to dive in., • You have grit. You’re used to hard tradeoffs and pushing through the messy middle to get to something great. ❌ This role is not for you if • You want remote or hybrid work. We believe early-stage startups win by moving fast in the same room — this is an in-office role, 5 days a week in our Old St office., • You dislike ambiguity. Priorities shift, experiments fail, and new opportunities appear — if you prefer stable roadmaps, this isn’t the place., • You don’t enjoy 0→1 environments. Early-stage means wearing multiple hats, solving unscoped problems, and building with imperfect information. 🤝 What we offer • Competitive salary + meaningful equity (EMI options): Everyone here has skin in the game and upside if we win., • Comprehensive benefits: Pension, private health insurance, and 25 days holiday plus bank holidays., • Real influence on architecture: You’ll make foundational decisions on our platform design that will shape how future engineers build on top of it., • Exposure across the startup stack: Beyond code — sit in on user interviews, shape product strategy, and get a front-row seat to how startups actually grow., • A team that’s genuinely excited: We’re obsessive about the problem, love what we’re building, and keep the culture sharp but supportive.
