Job Description
Mozilla's Ecosystem Services group builds and runs the server-side platforms behind its products. This remote, full-time Senior Software Engineer opening covers several back-end teams, each with distinct technical problems. The listing names Privacy Services, which provides APIs for Mozilla VPN, Relay, and Monitor; AutoPush, the Web Push service; and Remote Settings, which delivers configuration changes to Firefox between releases.
The engineer writes and maintains server-side code and integrations, helps evolve the cloud environment those services run in, and takes ownership from design through live operation. Responsibilities include shaping APIs and data contracts with frontend and platform colleagues, reviewing code, and taking part in security and privacy reviews.
The role includes a rotating on-call and off-hours schedule for triaging production problems, plus periodic time on support duty for releases, dependency upgrades, and inbound requests. Monitoring relies on tools like OpenTelemetry, Sentry, Prometheus, and Grafana, and the engineer partners with the CloudEng group to maintain production health. The listing encourages thoughtful use of AI-assisted coding tools.
Applicants need at least four years of software development with a substantial back-end emphasis, and experience with Python, TypeScript or Node.js, or Rust. Expected skills include PostgreSQL, query tuning, schema design and migrations, and Docker-based build and deployment on Google Cloud. Practical use of Sentry and Grafana, managing live services, and mentoring junior developers are also expected.
Bonus points for performance testing, Terraform and Kubernetes, open-source work, and Django. The listing does not describe benefits or give a salary.

- Hands-on GCP operations experience, including Docker build and deploy workflows
- Practical use of observability tools such as Sentry and Grafana
- Experience with on-call or out-of-hours support for production systems
