Senior UX Developer

We are looking for a Senior UX Developer to support the NIH Data Lakehouse. This role sits at the intersection of human-centered design, data-intensive workflows, and front-end engineering. The ideal candidate will help make complex research and operational experiences clear, efficient, accessible, and trustworthy for a diverse set of NIH users.

MEANINGFUL WORK AND PERSONAL IMPACT
You will help shape the data lakehouse user experience end to end, from discovery and workflow mapping through design, implementation, and iteration. Working closely with product owners, engineers, data and platform stakeholders, and leadership, you will translate platform needs into intuitive interfaces that support data discovery, access, governance, and collaboration.

What You’ll Do

UX/UI Design

• Lead human-centered design efforts for lakehouse workflows, from discovery through delivery
• Conduct user research, usability testing, and stakeholder interviews to inform design decisions for researchers, analysts, and platform administrators
• Create wireframes, prototypes, journey maps, user flows, and interaction models for data search, filtering, access, and review experiences
• Design interfaces that help users understand complex data, metadata, permissions, and status information with clarity and confidence
• Advocate for accessibility, inclusivity, privacy-aware design, and Section 508 compliance

Front-End Engineering

• Build high-quality, scalable UI components and features that support lakehouse workflows and dashboards
• Implement responsive, performant, and maintainable front-end architecture
• Collaborate with engineers to ensure design fidelity, technical feasibility, and consistency across the platform
• Integrate with GraphQL APIs, search services, and other backend systems that power data lakehouse use experiences
• Contribute to design systems, component libraries, and front-end best practices for platform-wide reuse

WHAT YOU’LL NEED TO SUCCEED

• 5–8+ years of experience in UX design, front-end development, or a hybrid role
• Strong portfolio demonstrating human-centered design thinking and shipped digital products or data platform experiences
• Proficiency with modern front-end technologies, including:
  • React
  • Next.js
  • GraphQL / GQL
  • React component kits
  • TypeScript and component-based architecture

• Experience conducting user research and translating insights into actionable design decisions
• Experience creating prototypes in relevant design or product tools
• Strong understanding of interaction design, information architecture, usability principles, and complex workflow design

Preferred Qualifications

• Experience supporting scientific, research, healthcare, or public-sector data platforms
• Experience with design systems at an enterprise scale
• Knowledge of performance optimization, SSR/ISR, and modern rendering strategies
• Experience designing engagement mechanisms, gamification features, or incentive-based user experiences that encourage platform adoption, data stewardship, collaboration, training completion, and effective use of enterprise data platforms
• Experience supporting Federal, HHS OpDiv, or NIH programs preferred
• Section 508 experience
