Senior Data Analyst, Lumina Data Platform

About the Role

Overview We are building a cloud-native data platform that ingests, governs, and serves data to teams across the company. We are looking for a Senior Data Analyst who can turn that data into clear, trustworthy answers — and document it well enough that others can reuse the work. You will sit close to the platform and its consumers, analyzing data to drive decisions while writing the queries, definitions, and guides that make the platform easier for everyone to use. This role blends deep analytical work with strong technical writing. You will not only produce analysis, you will document data sources, metrics, and how-to guidance so that self-service actually works. We move fast and use AI as a normal part of the job, so we want someone who reaches for those tools to raise the quality and speed of their work. Responsibilities What You'll Do Deliver analysis that drives decisions — scope questions with stakeholders, pull and model data from the platform, and turn it into clear findings and recommendations. Be the go-to expert on the platform's data — develop deep knowledge of the data model, the data it holds, and the platform's capabilities, and answer questions from consumers about what data exists, what it means, and how to use it. Own metrics and definitions — define, validate, and maintain the key metrics teams rely on, and keep them consistent across the platform. Write technical documentation — document data sources, schemas, metric definitions, and query patterns so consumers can find and trust the data without a meeting. Enable self-service — build reusable queries, dashboards, and how-to guides that let other teams answer their own questions. Safeguard data quality — profile new and existing sources, flag anomalies, and partner with data engineering to resolve issues at the source. Be a bridge to the platform — translate consumer needs into feedback for the platform team, and help onboard teams onto new data as it lands. Work AI-forward
