Join the mission to transform healthcare with Yazen health

Do you want to build technology that truly changes lives? At Yazen health, we’re not just another health tech company — we’re redefining how obesity is treated, combining medical expertise, behavioral science, and smart technology to help people achieve lasting, healthy change.

We’re expanding fast across Europe and are looking for a Full-Stack Engineer who’s ready to create impact, shape the future of digital healthcare, and grow with us.

Yazen was recently ranked #2 fastest-growing company in Europe by Sifted’s 2025 Startup Europe Leaderboard — and the #1 in the Nordics and Benelux with a revenue growth of nearly 80x in just two years

About Yazen Health
We believe healthcare should be personal, compassionate, and data-driven.

At Yazen, you’ll join a small, passionate team where ideas matter and ownership is real. Our work spans everything from patient-facing apps and journal systems to clinical tools and content creation — all with one goal: to make high-quality care accessible and effective.
If you’re driven by purpose, love solving tough problems, and want to see your code make a difference in people’s lives, you’ll fit right in.


Your Role
As a Full-Stack Engineer, you’ll be at the heart of our product development — turning ideas into experiences that inspire and empower our users. You will:

• Collaborate with designers, developers, and product minds to craft seamless, full-stack solutions that make healthcare smarter.

• Build and refine both front-end and back-end features for performance, reliability, and beauty.

• Write clean, maintainable, and testable code — and continuously raise the bar for quality.

• Explore, evaluate, and implement new technologies that make us faster, smarter, and more effective.

• Troubleshoot issues and deliver solutions with empathy — because every bug fixed means a better experience for a patient.
