Want to design a solution that mobilizes millions of people to take action on climate change? Looking for real ownership over your work, a tight-knit, collaborative team, and building the next big thing from the ground up? We’d love to meet you.

The opportunity

We are looking for a lead engineer who has experience at a rapidly scaling startup. The successful candidate will be responsible for the design and delivery of some of Commons' most important technical investments. Our development team is still small and you will be working across our full stack, from the React native app to the Node.js and Python servers, as well as with our hosting, testing, and continuous deployment infrastructure.

This is an individual contributor role, not a management position.


  • Working on key features of Commons' app and other technologies

  • Leading the technical design of features and systems (we're especially looking for someone with back-end expertise)

  • Mentoring the development team as they grow their technical skills


  • You are motivated to work on solving the climate crisis

  • You enjoy collaborating with a team

  • You have worked at a fast-growing start-up before and helped it scale

  • You are keen to mentor other software engineers

  • You want to make important decisions regarding the technical direction Commons
