Role: BI Lead (Power BI / Tableau)
Location: Gurugram/Pune (Hybrid)
Hire Type: FTE
Experience - 9+ Years
About the Role
Lead BI architecture and solution design conversations with clients, acting as the primary technical authority on data and analytics platforms.
Responsibilities
- Design, build, and optimize Power BI semantic models and Tableau data sources for enterprise-scale performance and maintainability.
- Write and optimise complex DAX measures, M/Power Query transformations, and SQL queries to support accurate, high-performance reporting.
- Diagnose and resolve data model issues — slow DAX, broken relationships, cardinality problems, and upstream data quality issues — quickly and systematically.
- Architect dimensional data models (star schema, fact/dimension design) and semantic layers consumed across multiple BI tools.
- Drive self-service BI capability: certify datasets, define governed metrics, and build enablement programmes so business teams can explore data independently.
- Define BI deployment standards, CI/CD pipelines, and release governance to ensure reliable and secure analytics delivery.
- Partner with data engineering teams to design analytics-ready data structures and resolve data issues at source.
- Establish data governance frameworks covering data quality standards, metadata management, access controls, and KPI standardisation across business units.
- Mentor BI developers through code and model reviews, sharing DAX, SQL, and design best practices to raise overall team capability.
Qualifications
- Power BI
- Semantic model design and optimization: star-schema modelling, reducing cardinality, managing relationships, aggregations, and composite models.
- Advanced DAX: efficient, reusable measures; evaluation context; CALCULATE; iterator functions; time intelligence patterns.
- M / Power Query: advanced transformations, query folding, incremental refresh, parameter-driven pipelines.
- Power BI Service governance: certified datasets, deployment pipelines, workspaces, row-level security, gateways, and refresh scheduling.
- Self-service BI: promoting dataset reuse and enabling business users to build their own reports without IT dependency.
- Tableau Dashboard and data source design for enterprise-scale reporting.
- Tableau Server / Tableau Cloud governance, published data sources, and performance optimisation.
- Strong SQL: complex queries, CTEs, window functions, query optimisation, and reading execution plans.
- Data warehouse and dimensional modelling: fact/dimension design, schema validation, and data lineage.
- ETL/ELT understanding diagnosing and resolving upstream data issues that affect BI layers.
Required Skills
- Comfortable presenting architecture, data strategy, and roadmaps to client executives and technical leaders.
- Skilled at requirements gathering from non-technical stakeholders and translating them into scalable BI solutions.
- Experience leading architecture reviews, discovery workshops, and solution design sessions.
Preferred Skills
- Snowflake: query optimization, warehouse sizing, and integrating Snowflake with Power BI or Tableau via Direct Query or native connectors.
- Sigma Computing: cloud-native self-service analytics on Snowflake; governed metrics, semantic model integration, and business user enablement.
- Experience connecting Sigma Computing with existing Power BI and Tableau ecosystems without creating governance gaps or data duplication.
- Working knowledge of policy lifecycle, claims, underwriting, premiums, loss ratios, and combined ratio.
- Ability to translate insurance business questions into structured KPIs, metrics hierarchies, and dashboard designs.
