Senior Software Engineer
Mozilla is seeking a Senior Software Engineer to join the Firefox Monitor Engineering Team, which develops tools that help users understand and respond to data breaches. This team notifies users when their credentials appear in exposed datasets, empowering them to regain control over their online privacy. Operating at scale and serving millions of users, the team's work intersects security, data privacy, and product engineering.
In this role, the engineer will lead backend development in Node.js and TypeScript within a Next.js full-stack architecture. Responsibilities include designing and maintaining integrations with external data sources, building event-driven systems using Google Cloud Pub/Sub, and managing cloud infrastructure on GCP and AWS. The engineer will also own and evolve the data layer, collaborate with the SRE team to maintain production environments, and support the frontend team to ensure seamless integration.
The ideal candidate will have over seven years of experience in software development with a strong focus on backend technologies. Deep expertise in Node.js and TypeScript is essential, along with proficiency in PostgreSQL and SQL query optimization. Experience deploying applications on Kubernetes, working with GCP and AWS services, and familiarity with observability tools like OpenTelemetry and Prometheus are also required. Strong communication skills and the ability to collaborate across teams are crucial.
Mozilla offers generous performance-based bonus plans, comprehensive medical, dental, and vision coverage, and substantial retirement contributions with immediate vesting. Employees enjoy quarterly wellness days, country-specific holidays plus a day off for their birthday, a one-time home office stipend, and annual professional development and well-being budgets. Considerable paid parental leave and an employee referral bonus program are also part of the benefits package.
Joining Mozilla means contributing to a mission-driven organization that values diversity, equity, inclusion, and belonging. The company encourages applications from all equity-seeking communities and provides reasonable accommodations for qualified individuals with disabilities. Mozilla is committed to building the internet as a public resource accessible to all, believing that open and free is better than closed and controlled.
