What you'll do

  • Create and maintain high-level overview dashboards that translate complex performance data into consumable formats for Product Managers and leadership
  • Audit the Gecko codebase to identify missing collection points or "probes" necessary for a complete understanding of the product experience
  • Develop methodologies and tools to identify and filter data inconsistencies, specifically focusing on isolating bot traffic and hardware-specific noise from telemetry streams
  • Deliver deep-dive analyses correlating technical performance shifts (e.g., LCP, eTLD+1) with user-facing pain points and engagement trends
  • Focus exclusively on Gecko engine telemetry across multiple platforms (Desktop and Android), collaborating with the Performance Team, Data Team, and Product Leadership

What we're looking for

  • Advanced SQL (BigQuery/Redash)
  • Proficiency in data visualization using AI tooling
  • Experience with statistical analysis (e.g., Pearson's correlation, multivariate analysis)
  • Ability to understand browser component interactions and their impact on user experience
  • Proven ability to work independently, translating technical requirements into business insights
  • Comfortable working in unfamiliar technical problem spaces and figuring out a path forward with minimal guidance, using documentation, experimentation, source code, data, and other available resources

Nice to have

  • Knowledge of Rust/C++
  • Strong proficiency with AI tools like Claude Code, Codex, or similar
