Prepare your resume, explore your fit, and draft a cover letter for this opportunity. AI Summary ## The role, at a glance. Mozilla is seeking a senior contract data analyst to improve the reliability and business usefulness of Gecko browser-engine telemetry. The role builds leadership-facing dashboards, audits telemetry collection gaps, and develops methods to remove bot and hardware-related noise from performance data. The analyst will connect technical measures such as LCP and eTLD+1 with user experience and engagement outcomes across desktop and Android. Success requires advanced SQL, statistical analysis, visualization, browser-platform fluency, and the ability to work independently with engineering, data, product, and leadership stakeholders. ## Role DNA A quick view of the complexity, pace, ownership and collaboration implied by the job description. ### Job Complexity 5/5EasyHard ### Pace & Pressure 4/5RelaxedFast-paced ### Autonomy Level 5/5GuidedFull ownership ### Communication Load 4/5IndependentCollaborative AI insightThis is a senior, technically demanding analytics role requiring trustworthy inference from noisy telemetry and enough browser-engine understanding to identify missing instrumentation.

The Canada Tier 1 employer range is CAD 93,450–124,600 per year, with a midpoint of CAD 109,025. The annual cadence is inferred from the range magnitude and senior professional scope because the posting does not explicitly state a pay period. A reasonable estimated Canadian annual market range for a senior telemetry/data analyst is CAD 90,000–130,000; this is an AI estimate, not verified salary research. ## Core skills Skills and capabilities most closely associated with this opportunity.

I would develop transparent filtering rules, validate their impact against known-good cohorts, and monitor exclusion rates so the framework does not remove legitimate users. Describe how you would investigate a decline in LCP after a Gecko change. I would first validate the telemetry pipeline and compare pre- and post-release distributions by platform, version, hardware class, geography, and key page or workload cohorts. I would then correlate the change with release metadata and user engagement signals, quantify uncertainty, and present likely drivers along with recommended follow-up instrumentation or experiments. How do you make a dashboard useful for both engineers and product leadership? I use a layered design: a concise executive overview with trends, guardrails, and clear interpretations, followed by drill-down views for technical segmentation and diagnostics. I align metrics and thresholds with concrete decisions, document definitions, and make data quality limitations visible. What approach would you take to finding missing telemetry probes in a large codebase? I would map the user journey and performance hypotheses to existing event schemas and code paths, then compare the signals needed for each decision against what is currently collected. I would review source code and documentation with engineering partners, propose minimally invasive probes, and define validation criteria before rollout. Tell us about working independently in an unfamiliar technical domain. I establish a structured learning plan using documentation, source code, exploratory queries, and conversations with subject-matter experts. I turn ambiguity into testable questions, share early findings and assumptions, and iteratively refine the analysis while maintaining clear documentation of decisions and limitations. Opportunity details ## About this role. The Gecko platform is the core engine of our product experience. To maintain competitiveness and user satisfaction, we must move beyond surface-level metrics to understand the deep correlations between engine performance and real-world user behavior. We currently face challenges with data quality, such as bot contamination in nightly telemetry, which obscures our understanding of true performance trends. A dedicated analyst is required to bridge the gap between engineering telemetry and actionable product strategy, ensuring that leadership has high-fidelity data to prioritize performance guardrails and technical budgets. ### Engineering Deliverables * Automated Dashboards: Create and maintain high-level overview dashboards that translate complex performance data into consumable formats for Product Managers and leadership. * Telemetry Gap Analysis: Audit the Gecko codebase to identify missing collection points or “probes” necessary for a complete understanding of the product experience. * Data Sanitization Frameworks: Develop methodologies and tools to identify and filter data inconsistencies, specifically focusing on isolating bot traffic and hardware-specific noise from telemetry streams. * Behavioral Inference Reports: Deliver deep-dive analyses correlating technical performance shifts (e.g., LCP, eTLD+1) with user-facing pain points and engagement trends. ### Scope, Skills, and Effort Estimate ### Scope The analyst will focus exclusively on Gecko engine telemetry across multiple platforms (Desktop and Android), collaborating with the Performance Team, Data Team, and Product Leadership. ### Required Skills * Technical: Advanced SQL (BigQuery/Redash), proficiency in data visualization using AI tooling, and experience with statistical analysis (e.g., Pearson’s correlation, multivariate analysis). Knowledge of Rust/C++ is a strong plus. Strong proficiency with AI tools like Claude Code, Codex, or similar is highly desirable. * Domain Knowledge: Ability to understand browser component interactions and their impact on user experience. * Soft Skills: Proven ability to work independently, translating technical requirements into business insights. * Independent problem solving: 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.
