Job Description

Senior Frontend Engineer (React + React Native)

Amsterdam / Hybrid (1 day/week) Up to €85K


Build products that genuinely improve lives - not just pretty dashboards.


A fast-growing mental health scale-up is hiring a Senior Frontend Engineer to take ownership of their React and React Native stack. The platform is already helping thousands of patients and clinicians across the Netherlands - now they're scaling fast and doubling down on great product experiences.


You'll be part of a small team working closely with product, backend, and AI experts. The vibe is startup-speed meets engineering maturity: fast-moving, quality-driven, and mission-led.


This is a frontend-heavy role. You'll be the go-to for everything UI-related, but there's still room to dip into backend APIs (C#/.NET Core) when needed. The codebase is clean, the CI/CD is solid, and you'll deploy to production often.


What you'll do


  • Help lead the frontend development across web (React) and mobile (React Native)
  • Build tools that directly support mental health professionals and patients
  • Work closely with product and design on intuitive, user-first experiences
  • Contribute to architecture, performance, and frontend strategy
  • Deploy often, test automatically, and move fast without breaking things


The stack


  • Frontend: React, React Native
  • Backend: .NET Core, Microsoft SQL
  • Infra: Azure, Docker, Azure DevOps


You'll bring


  • 5+ years of experience in frontend development
  • Strong React skills, and solid experience (or real interest) in React Native
  • Basic familiarity with backend APIs (C#/.NET is a plus, not a must)
  • A focus on clean, testable code and scalable UI patterns
  • Great communication and a collaborative mindset
  • Bonus: experience in scale-ups or mission-driven products


What's on offer


  • Up to €85K gross
  • Hybrid setup - just 1 day/week in a central Amsterdam office
  • Personal development budget + access to wellbeing support
  • A fast, no-nonsense product team with a clear mission


The product's already making an impact. This is your chance to help shape what comes next.
