Senior Full-Stack Engineer (AI App Builder)

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
