Lead Data Visualization Engineer

Summary

As Lead Data Visualization Engineer, you'll own the visualization and dashboard practice on a federal IT program responsible for disseminating high-impact public data to a broad audience. You'll design, build, and ship interactive dashboards in Tableau, Power BI, R, Python, and D3 — and make them accessible to every American who needs them under Section 508. The work runs from initial data preprocessing through deployment, performance tuning against large datasets, and bi-weekly delivery of transformed analytics to the customer. You're not advising — you're building. You'll standardize the visualization tool footprint, drive accuracy and usability through validation, and convert raw statistical data into products that change how decision-makers see their mission.

Responsibilities

Dashboard design & development

• Develop dashboards, user interfaces, and reports in compliance with accessibility standards
• Design, test, and deploy interactive reports using Tableau, Power BI, R, Python, and other approved tools
• Create custom calculations and apply filters for dynamic reporting
• Develop visual analytics for survey data and registration systems using approved tools
• Choose visualization types appropriate to data and objectives
• Implement visualizations with programming languages or visualization libraries
• Add interactive features to visualizations where required

Data preparation & quality

• Gather, preprocess, and normalize data for visualization
• Monitor connected data sources and ensure accuracy and timeliness
• Perform routine data cleaning and preprocessing
• Provide feedback on data reuse and perform cleansing to remove duplicates
• Test and validate visualizations to ensure accuracy and usability
• Maintain quality control and compliance with dissemination, visualization, and security governance

Performance & operations

• Optimize performance when working with large datasets
• Troubleshoot and resolve system and visualization errors
• Run reports on web interfaces and correct problems
• Standardize visualization tools and transform data analysis into actionable analytics
• Transform the interpretation and analysis of data into analytics delivered to the customer bi-weekly

Documentation & code delivery

• Deliver program documentation with purpose, programming steps, outputs, and accuracy assessments
• Submit program code to the Technical Monitor with internal comments and documentation
• Upon request, develop, assess, and customize existing tools/services across backend services such as database development, data protection, PowerShell scripting, server configuration, open-source coding, machine learning, and programming languages including R, D3, and Python

Required

• 7+ years building production dashboards in Tableau and Power BI
• Hands-on proficiency in R, Python, and D3.js for custom visualization
• Demonstrated experience with large-dataset performance optimization
• Section 508 / WCAG 2.1 AA accessibility experience in shipped products
• Experience with survey data and federal statistical systems strongly preferred
• Adobe Analytics and WCMS experience

Ideal Candidate

A craftsman who cares whether a colorblind user can read the dashboard. You've shipped public-facing federal visualizations that survived legal, accessibility, and press scrutiny. You're equally comfortable in a Tableau workbook, a Python notebook, and a D3 SVG — and you know when each is the right tool. You don't think of accessibility as a checkbox; you think of it as design constraint that makes the work better.
