Why work with us?

If you are an experienced software developer who wants both more flexibility in the schedule for family, personal growth, or health reasons, while still applying your skills in making a positive contribution to the world, then this is the perfect opportunity for you.

You will be building open-source software that distributes clothes, shelter, hygiene items, and food to thousands of refugees and other people in need. Your solutions will give comfort and dignity to people trapped in the most vulnerable of situations, from people relying on their local clothing bank to get their families through tough times, to unaccompanied minors stuck in a refugee camp in Greece, fleeing terrorism and violence in their home country. You will be responsible for driving a new release on a fresh technology stack and prepare our solution for a sustainable future. You will also be involved in supporting our executive board with preparing our organisation for an exciting new program that supports disadvantaged people by integrating graduates of nonprofit coding schools into our development team.

Grow your experience working in distributed, multicultural teams. Work with great people driven by a common purpose to improve the situation of vulnerable people. Learn from experienced founders including an ex-Amazonian and an ex-fintech CTO, who have decided to put the experience they’ve had building amazing products, running systems at scale, and operating in fast-paced, high growth environments to work in the humanitarian sector.

About Boxtribute
