About the Role

The Senior Software Engineer position at Mozilla is a critical role within the Firefox Monitor Engineering Team, which is responsible for developing tools that help users understand and respond to data breaches. As a senior engineer, you will be a core contributor to a modern, cloud-native Node.js/TypeScript full-stack application.

The team operates at the intersection of security, data privacy, and product engineering, serving millions of users worldwide. Your work will have a direct impact on helping users take back control of their online privacy. You will collaborate closely with frontend, SRE, and product teams to deliver reliable, privacy-first features.

Mozilla's mission to make the internet better for people, not companies, drives its focus on diverse areas such as AI, social media, security, and more. As a non-profit-backed technology company, Mozilla's commitment to open-source software enables people to enjoy the internet on their terms.

  • Build and maintain event-driven systems using Google Cloud Pub/Sub
  • Own and evolve the data layer, including PostgreSQL schema design and query optimization using Knex, and Redis caching strategies
  • Work closely with our SRE team to maintain and improve production environments, including monitoring and alerting with OpenTelemetry, Sentry, Prometheus, and Grafana
  • Collaborate with frontend teams to deliver cohesive user experiences
  • Participate in code reviews to ensure high-quality code and share knowledge with the team
  • Contribute to the development of cloud infrastructure on GCP (GKE) and AWS (S3, SES)

What We Are Looking For

  • 5+ years of experience in software engineering, with a strong background in Node.js and TypeScript
  • Experience with full-stack development, including backend and frontend technologies
  • Strong understanding of cloud-native applications and infrastructure
  • Proficiency in designing and implementing data-driven systems and integrations
  • Experience with PostgreSQL, Redis, and other database technologies
  • Strong collaboration and communication skills, with the ability to work in a distributed team
  • Experience with Excel for data analysis and reporting
  • Commitment to Mozilla's mission and values

Nice to Have

  • Knowledge of security and privacy best practices
  • Experience with containerization using Docker
  • Familiarity with agile development methodologies and version control systems like Git

  • Competitive salary and benefits package
  • Opportunity to work on a pioneering brand with a mission to make the internet better for people
  • Collaborative and dynamic work environment with a global team
  • Professional development opportunities, including training and conference sponsorships
  • Flexible working hours and remote work options
  • Access to the latest technologies and tools
