Senior Full-Stack Engineer (AI App Builder)

Summary

Builds the core AI App Builder platform: a full-stack system where users describe ideas and the platform generates functional apps, using React/Next.js, Node.js, and serverless/edge tech.

About Us

Our client is building an AI App Builder — a platform that allows anyone to create functional applications through natural interaction with AI. Users describe their ideas — and the system builds the app.

Their small, high-impact team is shaping the foundation of the product: architecture, interface, and AI integration layer. They’re looking for an experienced engineer with strong leadership skills, technical vision, and hands‑on experience in AI‑related projects, someone who can see the full picture — from code to product — and drive the team toward clean, scalable solutions.

  • Preference for Russian‑speaking engineers with experience in Western AI products.

Responsibilities

  • Lead the design and development of core platform features — from concept to production.
  • Define technical architecture for both frontend and backend systems, ensuring scalability and stability.
  • Collaborate with AI engineers and product designers to turn ideas into reliable, user‑ready functionality.
  • Take ownership of engineering quality, process efficiency, and release cadence.
  • Mentor and guide other developers; participate in technical decision‑making and planning.
  • Continuously improve system performance, UX, and developer workflows.

Requirements

  • 5+ years of professional experience as a Full‑Stack Engineer or Tech Lead.
  • Expertise in React / Next.js / Vue, TypeScript, and Node.js.
  • Strong understanding of API architecture, databases, and modern development tooling.
  • Experience working with serverless / edge environments (Cloudflare Workers, AWS Lambda, etc.).
  • Practical exposure to AI‑driven products (builders, agents, generative apps, etc.) — even up to one year is valuable.
  • Demonstrated leadership, ownership, and product vision — not just executing tasks but shaping direction.
  • Experience building fast‑moving products from scratch in startup environments.

Nice to Have

  • Familiarity with LLM APIs (OpenAI, Anthropic, Mistral, etc.).
  • Experience with Supabase, Docker, AWS, Vercel, or Cloudflare AI.
  • Background in real‑time collaboration, Web IDEs, or AI agent architectures.

Why Join Us

  • Build at the edge of AI innovation — creating tools that help others build with AI.
  • Influence not just the codebase but the entire direction of the product and engineering team.
  • Work in a lean, ambitious environment with full autonomy and real impact.
  • Become part of the core leadership group shaping a platform designed to redefine how software is created.
