Senior Data Analytics Contractor

About

We are seeking a Senior Data Analytics Contractor to deliver end-to-end analytics solutions across modern data platforms. You will build and optimize datasets in SQL Server, Snowflake, and Microsoft Fabric, develop analytics in Python, and deliver executive-ready insights through Tableau and Power BI. You will also leverage Microsoft Copilot and other AI-assisted tools to accelerate analysis, development, documentation, and stakeholder support—while applying strong validation, governance, and data quality practices.

Key Responsibilities

• Gather requirements, define KPIs, and translate business needs into scalable analytics deliverables (datasets, semantic models, dashboards, and insights).
• Write and optimize advanced SQL across SQL Server, Snowflake, and Microsoft Fabric (Warehouse/Lakehouse).
• Design and maintain analytics-ready data models (dimensional/star schemas, curated layers, reusable views/tables).
• Build, enhance, and performance-tune dashboards and reporting in Power BI (DAX, Power Query, semantic models) and Tableau.
• Use Python (e.g., pandas, NumPy; optional scikit-learn/statsmodels) for data wrangling, statistical analysis, forecasting, experimentation support, and automation.
• Implement data validation and quality controls (reconciliation, anomaly checks, refresh monitoring, metric certification).
• Develop within Microsoft Fabric using relevant components (e.g., notebooks, Dataflows Gen2, pipelines, Lakehouse/Warehouse, semantic models) as applicable.
• Leverage Microsoft Copilot and AI tools (e.g., Copilot for Power BI/Fabric/M365 and other approved assistants) to:
  • accelerate SQL/DAX generation and refactoring,
  • speed up dashboard prototyping and narrative insights,
  • draft documentation and data dictionaries,
  • support stakeholder Q&A and self-service enablement, while ensuring correctness through testing and peer/stakeholder validation.
• Communicate findings clearly, create concise executive narratives, and recommend actions backed by data.
• Maintain documentation for metric definitions, logic, lineage, and operational runbooks to support handoff.

Required Skills & Experience

• 7 - 10+ years in data analytics/BI/consulting (or equivalent senior-level experience).
• Advanced SQL expertise (CTEs, window functions, complex joins, query tuning).
• Strong experience with SQL Server (T-SQL) and performance optimization.
• Experience with Snowflake (warehouse concepts, optimization/cost awareness, security basics).
• Hands-on experience with Microsoft Fabric (Lakehouse/Warehouse concepts; pipelines/dataflows/notebooks; semantic modeling).
• Strong dashboard development skills in Power BI (DAX, modeling, performance) and Tableau.
• Proficiency in Python for analytics and automation.
• Demonstrated ability to use AI-assisted tools productively with appropriate guardrails (validation, privacy, reproducibility).
• Excellent stakeholder management, communication, and independent delivery skills.
