Full-stack Engineer

We're hiring a full-stack engineer to help build Wren!

Full-stack Engineer

Learn more about Wren's climate projects.

Why this Role?

  1. Work on ending the climate crisis. Help us build a product that gets millions of people to do something about climate change. Each feature grows our impact.
  2. Build features that matter. The most popular project on Wren is a tree planting project that pays subsistence farmers to plant trees. Beyond the carbon impact, our projects change lives. You’ll be building features that help bring funding to projects that address climate change and improve lives around the world.
  3. Have the opportunity to extend beyond engineering. If you’re interested, you can design the features you’re building or help make business decisions with analytics.
  4. Choose your future. You will grow with us - Wren is still just beginning, and you will shape our trajectory as well as your own. As we grow, you'll be able to grow into your dream role and shape the future of the product as well as the company.

What you'll do

  • Build new product features from start to finish: from first MVP to fully polished interfaces
  • Implement UI changes for A/B tests
  • Optimize performance and improve site reliability when necessary
  • Provide input on our product roadmap, and help spec features from high level concepts to actionable tasks
  • Shape our product culture and improve our processes for ideation, design, development, deployment, and monitoring
  • And more — you’re encouraged to build anything you come up that you think could be useful to our users!

  • You like launching features quickly and iterating on them based on data
  • You have a growth mindset and enjoy learning new things, especially when it’s important to the team’s success
  • You love learning about the climate crisis and are excited about building a product that helps individuals save the planet
