💙 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. You’ll design and build features across the stack, continuously improve our architecture, and help us scale a product that matters.

We’re looking for someone who thrives in a fast-moving product environment, who loves solving challenges with simplicity, and who’s eager to grow by experimenting, learning, and pushing boundaries.

• Take ownership of features from idea to release and beyond.

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.
