Senior Frontend Developer

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.
