Why Mozilla?

Mozilla Corporation is the non-profit-backed technology company that has shaped the internet for the better over the last 25 years. We make pioneering brands like Firefox, the privacy-minded web browser, and Pocket, a service for keeping up with the best content online. Now, with more than 225 million people around the world using our products each month, we’re shaping the next 25 years of technology and helping to reclaim an internet built for people, not companies. Our work focuses on diverse areas including AI, social media, security and more. And we’re doing this while never losing our focus on our core mission – to make the internet better for people. 

The Mozilla Corporation is wholly owned by the non-profit 501(c) Mozilla Foundation. This means we aren’t beholden to any shareholders — only to our mission. Along with thousands of volunteer contributors and collaborators all over the world, Mozillians design, build and distribute open-source software that enables people to enjoy the internet on their terms. 

About this team and  role:

Mozilla’s Core Services team is looking for a Principal Software Engineer to help build and maintain software platforms, services, and tools to accelerate our product engineering teams. Core Services’ mission is to enable customer teams using our service infrastructure to spend more time meeting end-customer needs and reduce the time they spend on common software elements that many teams need to test, deliver, and monitor software applications. Problem spaces within the scope of the Core Services team include observability, CI/CD, remote configuration, incident response, and technical review and decision processes. 

Principal Engineers are industry experts in their domain. They work with senior leadership to define our product strategy and goals affecting multiple teams and turn our strategy into coordinated action for those teams.  They manage ongoing cross-cutting technical risk and lead architectural decisions to reduce that risk. They collaborate with senior management to drive engineering and cultural change across departments. They find common pain points across the technical organization and set a strategy to address those issues. 

What you’ll do:

• Define, and then build, a more consistent developer experience at Mozilla so we can develop new products faster and easier. You’ll bring our developer experience closer to a unified/shared internal platform and lead the strategy for service ownership at Mozilla. 
• Identify common challenges shared across multiple teams and build solutions that ease those pain points. Current domains that are in need of attention include the Observability and CI/CD problem spaces. 
• Build out a shared internal platform for product teams to access tools that increase their efficiency and productivity.
• Shift teams out of a reactive operating model to a strategic, proactive model. 
• Mentor junior engineers so that they can grow and take ownership of more complex projects.

What you’ll bring: 

• 10 years of professional experience in software development
• Strong experience with service ownership:  building, shipping, and supporting services throughout their lifecycle
• Ability to identify, prioritize,  and execute on cross-cutting problems that impact the organization, collaborating across multiple teams as needed to find the optimal strategy and deliver a solution
• Proven track record of leadership across teams, showing a high degree of collaboration, flexibility, and respect for diverse perspectives
• Strong problem-solving skills and ability to communicate complex concepts to both technical and non-technical audiences
• Ability to influence roadmaps and execution in the teams we partner with
• Excellent written and verbal English communication skills and experience participating effectively on a distributed team

What you’ll get:

• Generous performance-based bonus plans to all regular employees - we share in our success as one team
• Rich medical, dental, and vision coverage
• Generous retirement contributions with 100% immediate vesting (regardless of whether you contribute)
• Quarterly all-company wellness days where everyone takes a pause together
• Country specific holidays plus a day off for your birthday
• One-time home office stipend
• Annual professional development budget
• Quarterly well-being stipend
• Considerable paid parental leave
• Employee referral bonus program
• Other benefits (life/AD&D, disability, EAP, etc. - varies by country)
