Frontend Developer – HealthTech Startup | Stockholm (Onsite)

Type: Permanent, Full-Time

A well-funded, early-stage HealthTech startup based in Stockholm is looking for a Frontend Developer to join their growing team.

• Ensure smooth integrations and high performance across the product stack
• Shape new features based on customer feedback and real-world data
• Play a key role in product evolution, with the opportunity to step into a technical leadership position

What They’re Looking For:

• 3–5+ years of professional software development experience
• Solid hands-on experience with React Native (Expo)
• Practical mindset: know when to build from scratch vs. leverage tools/packages
• Familiarity with fast-paced startup environments, ideally with experience launching early-stage products
• Bonus: experience with Elixir/Phoenix

Why You’ll Like It Here:

• Genuine impact: your work can improve health outcomes for children globally
• Equity options & 30 days of vacation
• Career path to tech lead / CTO
