Job Description

Role Overview

We're building a new platform from the ground up, and we need a senior full-stack developer who lives and breathes AI-assisted development. This isn't about someone who's tried ChatGPT a few times - we need someone who uses AI agents daily, experiments with every new AI coding tool, understands Claude Code, Codex, and Cursor/Windsurf deeply, and can establish team standards for AI collaboration (CLAUDE.md/AGENTS.md, agent workflows).

But here's the critical part: we need someone who knows how to build production-grade systems with AI, not just MVP prototypes. You should have battle-tested experience implementing AI in large development processes while maintaining code quality, security, and testability. You know the difference between AI-generated spaghetti code and well-architected AI-assisted development.

You'll be launching and driving development of our new platform: end-to-end integrations, frontend, backend, architecture, and deployment - all with emphasis on performance, security, and maintainability at scale.

What you’ll do

• Design the platform architecture and ship the initial version end-to-end.
• Build APIs, frontend, backend, and CI/CD; ensure observability and security from day one.
• Establish AI-assisted development guardrails (Cursor rules, agents.md, code quality gates).
• Create testing strategies that work with AI-generated code and prevent regressions. Evaluate new AI dev tools responsibly; accelerate delivery without adding tech debt.

Qualifications

What you bring

• 5+ years of full-stack experience; shipped and operated production systems at scale.
• Strong API design/integrations, security fundamentals, testing, and CI/CD.
• Daily user of AI coding tools (Cursor, Claude Code, Codex, etc.) with clear guardrails.
• Ability to turn engineering standards into practice and mentor others by example.
• Clear communication and comfort working directly with product/design/infrastructure.

Tech baseline (preferred)

• Frontend: React, TypeScript, shadcn/ui, Tailwind CSS (Angular knowledge is a strong plus).
• Backend: Python (FastAPI), Node.js; OpenAPI/Swagger for auto-docs.
• Ops: Version control (GitHub/GitLab), containerization (Docker/K8S), monitoring & alerting (PLG/LGTM Stack).

(We’ll finalize choices together - expect to influence the stack.)

Team & ways of working

• Early stage: you’ll work directly with the product lead; first hire on the team.
• Outcomes and roadmap will be co-defined in the first weeks; we value fast learning loops.
• AI-first, quality-driven: speed with guardrails, data/privacy aware, zero-tolerance for spaghetti code.
• We have our team of AI developers, and you will be part of the team working on another project, where you will have the opportunity to share your knowledge with them.

Not a fit if you

• Rely on AI to generate code you don’t understand.
• Trade quality and security for velocity.
• Haven’t built or run production systems.

Why join us

• Greenfield ownership and decision rights on architecture and tooling.
• Real impact at scale across a multi-product cloud company.
• Budget and autonomy to push the state of the art in AI-assisted development.
