Teams at Mozilla

Designs, deploys, and operates software, developer tools, CI/CD systems, workflow automation, and cloud infrastructure supporting Firefox engineering. The role owns complex reliability, performance, observability, and cost-efficiency problems; uses telemetry and metrics for decision-making; collaborates across engineering and IT; contributes to architecture and technical strategy; and helps establish reusable operational standards and open-source solutions.

Lead and mature Mozilla's ISMS and compliance programs (ISO 27001, SOC 2), support audit execution and evidence collection, manage policy lifecycle, track remediation and internal audits, and partner with cross-functional teams to translate compliance requirements into practical controls and processes.

Investigate and modify browser engine subsystems through hands-on experimentation, prototyping, instrumentation, profiling, and performance analysis. Build capabilities supporting reliable programmatic web interaction while evaluating correctness, compatibility, and efficiency. The role requires deep browser internals expertise, strong C++ or Rust proficiency, systems debugging experience, and understanding of web platform behavior. Engineers will collaborate with technical leadership, use AI-assisted development tools, and document reproducible results, including unsuccessful experiments.
