Staff Software Engineer AI Agents

Build browser engine capabilities remotely from Canada, using profiling and AI tools to improve reliable programmatic web interaction. Investigate performance with evidence.

As a Staff Software Engineer on Mozilla’s new products team, you will prototype capabilities supporting interaction with web content. Your work examines document structure, layout, navigation, event handling, and performance. You will also connect implementation choices with information available to AI agents.

Key Responsibilities:

• Prototype engine capabilities for reliable programmatic web interaction
• Investigate document structure, layout, navigation, and event handling
• Profile overhead introduced by new capabilities
• Pursue improvements supported by performance measurements
• Use AI tools, debugging, tests, and measurement

Requirements:

• Investigate unfamiliar code and form precise hypotheses
• Construct useful prototypes and interpret their results
• Experience with profiling, tracing, regression, or conformance tests
• Ground performance claims in reproducible evidence
• Curiosity about AI agents and coding tools

Apply staff-level engineering judgment to browser capabilities, AI-assisted development, profiling, testing, and measurable performance improvements at Mozilla.
