Core Responsibilities

Primary Functions

  • Design, develop, and maintain interactive dashboards and executive reports using Tableau, Power BI, Looker, or other BI platforms to provide timely, actionable insights and drive measurable business outcomes.
  • Translate complex business requirements and stakeholder interviews into intuitive visualizations and end-to-end dashboard solutions that enable rapid decision-making across product, marketing, finance, and operations teams.
  • Collaborate with data engineering and analytics teams to define data schemas, ETL pipelines, and dimensional models that ensure the accuracy, consistency, and performance of visualization-ready datasets.
  • Create custom, high-performance visualizations using JavaScript libraries such as D3.js, Vega-Lite, or Plotly, and embed interactive charts into internal web applications or customer-facing portals.
  • Author and optimize SQL queries, aggregated tables, and materialized views to minimize dashboard load times and improve concurrent query handling for large-scale datasets.
  • Conduct user research, usability testing, and stakeholder workshops to iterate on information hierarchy, chart types, and navigation patterns that increase dashboard adoption and reduce misinterpretation of metrics.
  • Establish and maintain visualization standards, charting guidelines, style systems, and templated components that enforce branding, accessibility, and consistency across all BI artifacts.
  • Implement and administer row-level security, dataset permissions, and governance controls to ensure sensitive data is protected and access is auditable across dashboards and reports.
  • Perform rigorous exploratory data analysis to identify trends, anomalies, seasonality, and root causes, and document findings with reproducible code, notebooks, and narrative summaries.
  • Build automated reporting pipelines, scheduling, and alerting for critical business KPIs, ensuring stakeholders receive timely insights and can act on exceptions without manual intervention.
  • Provide hands-on training, onboarding sessions, and written documentation for business users and analysts to foster self-service analytics and reduce recurring ad-hoc reporting requests.
  • Partner cross-functionally with product managers, marketing leads, and finance to define measurable goals, design A/B test visualizations, and report experiment outcomes with statistical rigor.
  • Troubleshoot, triage, and resolve production data discrepancies, visualization bugs, and performance regressions while coordinating with engineering teams to deploy robust fixes and monitor outcomes.
  • Maintain an organized backlog of visualization projects, estimate effort, prioritize by business impact, and participate in agile rituals to ensure timely delivery of analytics features.
  • Integrate and normalize third-party data sources such as Google Analytics, Salesforce, Mixpanel, and ad platforms into unified dashboards to support cross-channel attribution and performance reporting.
  • Implement CI/CD practices, version control, and deployment strategies for dashboard artifacts and visualization code to streamline releases and enable rollback if needed.
  • Monitor dashboard usage metrics, collect user feedback, and run continuous improvement cycles to optimize clarity, speed, and ROI of analytics deliverables.
  • Translate technical and analytical findings into executive-level presentations, one-pagers, and slide decks that clearly articulate insights, risks, and recommended next steps.
  • Create accessible visualizations that comply with WCAG guidelines — ensuring appropriate color contrast, keyboard navigability, and alternative descriptions for critical charts.
  • Conduct data lineage, metadata, and cataloging activities to improve discoverability, trust, and reuse of visualization datasets across teams.
  • Evangelize data visualization literacy and best practices across the organization through workshops, office hours, and internal communications that uplift analytics maturity.

Secondary Functions

  • Support ad-hoc data requests and exploratory data analysis.
  • Contribute to the organization's data strategy and roadmap.
  • Collaborate with business units to translate data needs into engineering requirements.
  • Participate in sprint planning and agile ceremonies within the data engineering team.
  • Assist in vendor evaluations and proof-of-concept (POC) activities for new BI tools, visualization libraries, or analytics platforms.
  • Mentor junior analysts and visualization designers on chart selection, storytelling techniques, and technical implementation best practices.
  • Maintain documentation for dashboard architecture, data transformations, and access procedures to support auditability and onboarding.
