At Affinity Labs, we’re building 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 monetisation by rapidly building, launching, and scaling digital ventures alongside 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.
Ship at rapid pace with AI-accelerated workflows, see your work distributed to tens of thousands of users at launch, and compound impact across multiple products, not just one. You’ll lead end-to-end product engineering across our portfolio: scoping features, designing APIs and data models, building backend services, and shipping polished user-facing experiences across web and mobile.
You will own full-stack product delivery, from infrastructure and AI integrations through to React / React Native interfaces, collaborating closely with founders, creators, product, and design to turn lean specs into scalable, user-loved software.
Implement features end-to-end (mobile + web frontend → APIs → data models → integrations) while maintaining quality and velocity. Build React Native mobile apps and shared component systems across products. Design and ship scalable backend services (APIs, integrations, AI workflows). Run tight build → test → iterate → ship loops; Participate in daily standups and weekly planning; CI/CD, monitoring/alerting, performance optimisation, safe rollbacks.
Build and integrate AI features (LLM/agent workflows, RAG/vector DB integration, eval hooks, cost/safety guardrails). Help evolve our reusable product templates and shared architecture across the portfolio.
- 3-6+ years building production-grade full-stack applications, with clear ownership.
- Strong backend experience in Python (FastAPI preferred) and solid database skills (PostgreSQL/MongoDB).
- Proven experience building and shipping mobile apps with React Native.
- Strong React fundamentals (Next.js experience a plus).
- Familiarity with AWS serverless patterns and Docker.
- Startup mindset: high ownership, comfort with ambiguity, bias toward shipping.
- Evidence of shipping quickly in small teams (links to apps, repos, case studies, live products).
Experience with vector databases (e.g., MCP servers for integrations). Security hygiene (secrets, permissions, least-privilege) and practical data-privacy basics. Planning & execution in Linear (or similar).
Frontend: React/Next.js, React Native. Databases: PostgreSQL, MongoDB (as appropriate), Redis (caching/sessions). AI Models & APIs: Claude (Anthropic), Gemini (Google); Amazon Nova Canvas (vision), Deepgram (audio). AI Dev Tools: LangChain or CrewAI (orchestration), MCP servers (integration), GitHub Copilot / Claude Code. Infrastructure: AWS (serverless functions), Docker (primarily for custom MCPs).
We need driven people who can help us achieve an ambitious roadmap. The shipping reps you’ll get in 12 months here would take 3–4 years in a typical startup. There’s a lot of work, it’s high intensity, and the expectation is to ship extremely quickly.
