We're looking for a senior full-stack engineer to help build the core platform - the decision engine, the admin interface, and the integrations that connect Mister Chameleon to the tools our customers already use.

You'll own significant parts of the product. You'll write code, review code, and help shape the technical direction of a platform that processes millions of personalisation decisions every day.

What you'll work on: Edge Middleware decision logic in Next.js 15 (TypeScript). The Sanity-based CMS integration and content variant system. The admin dashboard: rules editor, analytics, billing, and white-label tooling. API endpoints consumed by the tracking snippet and third-party integrations.

What we're looking for: 5+ years of professional software development. Strong TypeScript and modern React. Experience with Next.js (App Router preferred). Comfort working with databases (PostgreSQL / Supabase). Interest in edge computing, personalisation, or data infrastructure. Clear written communication - we're async-first.

What we offer: Competitive salary (€70,000-€95,000 depending on experience). Equity. Remote-first - work from anywhere in Europe. 25 days holiday. Annual learning budget (€1,500). Fast decision-making - no approval chains.
