Senior Data Analyst

TriOptus LLC

Job Description:


Role Summary


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.

Deliverables / Success Measures
• Reliable, documented KPI definitions and curated datasets used consistently across teams.
• High-performing, user-friendly dashboards in Power BI/Tableau with measurable adoption.
• Reduced manual reporting through automation and reusable analytics assets.
• Clear documentation and handoff materials enabling maintainability after contract


completion.
