Senior Data Analyst – Decision Science (SQL-Focused)

Data Analyst – Cost Estimation & Insights (SQL-Heavy) Our client is seeking a data-driven problem solver to join their core cost estimation team. This role is best described as a “Business Analyst on steroids”—focused on deep data investigation, root-cause analysis, and insight generation within production data environments. This is not a machine learning or advanced modeling role. The ideal candidate thrives in SQL, enjoys untangling complex data issues, and can translate business logic into clear analytical findings. Key Responsibilities • Investigate and analyze complex data issues within cost estimation outputs, including identifying erroneous, missing, or illogical results • Use SQL extensively to mine large datasets, uncover patterns, and determine why issues are occurring—not just that they exist • Translate business rules and product logic into clear analytical queries and insights • Perform root-cause analysis on production issues such as service failures, inconsistent outputs, or data gaps • Communicate findings clearly to product and technical partners to inform prioritization and product improvements • Support ongoing product maturity as solutions move into and operate within production environments Ideal Candidate Profile • Very strong SQL skills are required; this is a query-heavy, insight-driven role • Solid (but not advanced) Python skills are acceptable; Python is secondary to SQL • Exceptional data mining and analytical reasoning skills, with the ability to independently investigate ambiguous or open-ended problems • Strong logical thinker who can connect business rules to real-world data behavior • Prior healthcare data experience is highly preferred due to the complexity of the datasets • Comparable skill set to a high-performing senior analyst or decision scientist What This Role Is Not • Not a machine learning or statistical modeling role • Not focused on advanced data science techniques • Not primarily an executive presentation role Why This Role Matters As the client’s product continues to operate in production, data anomalies, investigation requests, and insight needs are increasing. This role is critical to enabling faster issue diagnosis, smarter prioritization of fixes, and continuous product improvement.
