About the role
- Senior Software Engineer on Ecosystem Services Team at Mozilla developing backend systems. Owning services end to end, collaborating with cross-functional teams for reliable features.
Responsibilities
- Lead backend development, building and maintaining server-side logic
- Take real ownership of the services you work on: deploy them, operate them, and keep them healthy in production rather than handing them off
- Work closely with our CloudEng Team to maintain and improve production environments, including monitoring and alerting with tools such as OpenTelemetry, Sentry, Prometheus, and Grafana
- Participate in an on-call / off-hours support rotation, triaging and resolving production issues, partnering with CloudEng and support teams to investigate incidents, address bug reports, and keep the application running reliably
- Periodically rotate into a support role, handling releases, dependency updates, and incoming work requests from customer support and other stakeholders
- Thoughtfully apply AI-assisted development tools to move faster and raise quality, while maintaining good judgment about where they fit and where they don't
- Partner with and support stakeholders (e.g. front-end, platform), ensuring backend systems, APIs, and data contracts meet their needs
- Partner with frontend and cross-functional teams to align on project goals, contribute to API design, and ensure backend systems, APIs, and data contracts meet their needs
- Participate in code reviews to maintain high standards of code quality and system reliability
- Participate in security and privacy reviews, ensuring all data protection measures meet compliance standards
Requirements
- 4+ years of experience in software development with a strong focus on backend technologies
- Strong professional experience with Python, TypeScript/Node.js, or Rust building back-end services and confidence leading back-end engineering projects.
- Proficiency with PostgreSQL and SQL query optimization, including relational schema design and migrations with a query builder such as Knex
- Hands-on DevOps experience on Google Cloud Platform (GCP), with Docker-based build and deploy pipelines. You are comfortable deploying, operating, and troubleshooting services in the cloud rather than handing that responsibility to someone else
- Hands-on experience with observability and monitoring tooling such as Sentry and Grafana
- A pragmatic commitment to shipping quality work. You care about the quality and reliability of what you ship, you make sensible trade-offs under real constraints, and you consistently move work to and into production.
- Strong engineering judgment. You can navigate ambiguity, weigh trade-offs, and make sound decisions with incomplete information, and you know when to ask for input
- A genuine ownership mindset. You are excited to own a service end to end and have a track record of operating what you build in production, including experience with on-call or off-hours production support
- Experience mentoring junior engineers and driving technical excellence in code quality, testing, and process improvements
Benefits
- Generous performance-based bonus plans to all eligible 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)
