Release Engineering Team

Mozilla Corporation is seeking a skilled Software Engineer to join our Release Engineering team. As a key member of our engineering infrastructure, you will play a crucial role in ensuring the seamless and reliable delivery of our world-class software products.

Our Release Engineering team is responsible for the continuous deployment of our products, ensuring they reach our users efficiently and without interruption. We pride ourselves on our collaborative and dynamic work environment, where engineers are problem-solvers who thrive on tackling complex challenges and continuously seek to improve our infrastructure.

As a Software Engineer on our Release Engineering team, you will be responsible for:

  • Helping chart the future path of Mozilla's Release Engineering team
  • Writing software that scales - tens of thousands of tasks are run to build, test, and release Firefox every single day
  • Troubleshooting, resolving, and optimizing deployment and infrastructure issues on a large existing codebase - with an emphasis on stability and long term planning
  • Working with a geographically-distributed development team between North America and Europe
  • Collaborating with other teams by providing code review and technical direction
  • Mentoring other team members and being mentored by more senior team members
  • Responding to critical service outages (during normal working hours - no on call rotation is required)

We are looking for a candidate with a minimum of 5 years of experience working in an object-oriented programming (OOP) language (preferably Python), and a proven track record of finishing projects where the work spans several months. You should be comfortable developing in Windows, macOS, and Linux environments, and have experience with shell scripting.

We offer a generous performance-based bonus plan, rich medical, dental, and vision coverage, and a comprehensive benefits package. If you are passionate about continuous deployment and automation, and are looking for a challenging and rewarding role, please apply.
