Job Description
We are hiring for our client – a growing company undergoing a major software modernization initiative – for a Senior React Frontend Developer to join their team. Location: Almere, Netherlands (Hybrid).
Company: Confidential (details shared at later stage)
Location: Almere, Netherlands (Hybrid)
Position: Senior React Frontend Developer
About the Role
Our client is in the midst of a major software modernization initiative – completely dismantling their legacy platform in favor of a scalable, modern ecosystem built on React, Next.js, and AWS. They are looking for a frontend engineer with a deep understanding of web fundamentals (native browser mechanics, DOM manipulation, complex state management, performance optimization), who will also lead the adoption of AI Spec-Driven Development (SDD) across the team.
Key Responsibilities:
- Spearhead the legacy platform modernization – architect and lead the frontend rebuild into a modern React/Next.js environment
- Champion AI Spec-Driven Development – eliminate ad-hoc "vibe coding" in favor of structured AI workflows built on comprehensive specification frameworks
- Draft and maintain living specs – own the full SDD lifecycle: writing project constitutions, defining feature intent, translating requirements into technical architecture, and orchestrating AI implementation
- Design scalable, modular frontend architecture that integrates seamlessly with AWS infrastructure
- Act as the strategic gatekeeper for AI-generated code (Copilot, Claude, Gemini), ensuring it adheres strictly to specifications and enterprise-grade quality standards
- Mentor and upskill mid-level engineers – both in elite React patterns and spec-first AI development methodology
Required qualifications
Core Requirements (Critical):
- 🚨 Expertise in React and AI Spec-Driven Development – hands-on experience (or deep theoretical mastery) of spec kits and spec-first methodologies; ability to lock in constraints, edge cases, and architecture before any AI-generated code is produced
- 🚨 Leadership & Team Enablement – proven track record of leading from the front, with the communication skills to mentor and elevate the entire engineering team
- 5+ years of experience – unrivaled expertise in React, modern JavaScript/TypeScript, and Next.js; deep mastery of performance optimization, complex state management, and web fundamentals
- Migration mastery – battle-tested experience breaking down and migrating large legacy monoliths into modern, component-driven architecture
- Systems thinking – pragmatic, architectural mindset; understanding of AI as an execution engine, with the human engineer providing the master blueprint
Nice to Have:
- Strong familiarity with deploying containerized or serverless frontend applications on AWS
- Knowledge of or experience with microfrontend architectures (Webpack Module Federation, single-spa)
- Familiarity or hands-on experience with React Native for cross-platform mobile development
Why This Role?
A rare opportunity to be at the bleeding edge of AI-native engineering – not just building React components, but writing the playbook for automated, spec-driven workflows that enable rebuilding complex enterprise software with speed, precision, and power.
Do you have experience with spec-driven tools (e.g. spec kit, structured prompting for AI agents), or have you led migrations of large legacy systems?
