Arbetsbeskrivning

💙 Sellpy’s vision is to empower everyone to live circularly. We believe that every item deserves a second life, and we see huge financial, social and environmental value in making sure this happens. Join us in building technology that drives real change – one line of code at a time.

Fullstack Engineer

At Sellpy, we love elegant code and we hope you do too. Your work will be at the core of how millions of people shop pre-loved items, making circular consumption the new normal.

• 3+ years of professional software engineering experience.

We think you’re someone who’s curious, open-minded and enjoys learning new things. You like collaborating with others, sharing ideas and finding simple solutions to complex problems. With a positive mindset and a drive to make a difference, you bring both energy and creativity into your work.

We’d be impressed if you have

• Experience with React, React Native, Node.js, Web Components, logging & monitoring.
