Contract Senior Data Analyst (SQL,Telemetry,Browser Engine)

<p>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.</p> <h3><strong>Engineering Deliverables</strong></h3> <ul> <li><strong>Automated Dashboards:</strong> Create and maintain high-level overview dashboards that translate complex performance data into consumable formats for Product Managers and leadership.</li> <li><strong>Telemetry Gap Analysis:</strong> Audit the Gecko codebase to identify missing collection points or "probes" necessary for a complete understanding of the product experience.</li> <li><strong>Data Sanitization Frameworks:</strong> Develop methodologies and tools to identify and filter data inconsistencies, specifically focusing on isolating bot traffic and hardware-specific noise from telemetry streams.</li> <li><strong>Behavioral Inference Reports:</strong> Deliver deep-dive analyses correlating technical performance shifts (e.g., LCP, eTLD+1) with user-facing pain points and engagement trends.</li> </ul> <h3><strong>Scope, Skills, and Effort Estimate</strong></h3> <h3><strong>Scope</strong></h3> <p>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.</p> <h3><strong>Required Skills</strong></h3> <ul> <li><strong>Technical:</strong> 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. </li> <li><strong>Domain Knowledge:</strong> Ability to understand browser component interactions and their impact on user experience.</li> <li><strong>Soft Skills:</strong> Proven ability to work independently, translating technical requirements into business insights.</li> <li><strong>Independent problem solving:</strong> 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.</li> </ul> <p><strong>Hiring Ranges:</strong></p> <p>Remote UK</p> <p>£58,500—£78,000 GBP</p>
