- Implement client-side data redaction, anonymization displays, and audit logging for compliance requirements
- Build secure authentication/authorization flows and session management patterns
- Ensure WCAG 2.1 AA accessibility compliance across all interfaces
Collaboration & Operationalization:
- Partner with Data Science teams to visualize statistical models, quantitative insights, and AI-generated summaries
- Collaborate with backend engineers to define optimal API contracts, data shapes, and performance characteristics
- Work with UX designers to translate wireframes and design systems into production-ready, pixel-perfect implementations
- Translate product requirements and analytical needs into technical designs and execution plans
Performance & Quality:
- Optimize application performance including bundle sizes, lazy loading, code splitting, and runtime performance
- Implement comprehensive testing strategies (unit, integration, E2E, visual regression, accessibility)
- Establish observability and monitoring for front-end errors, performance metrics, and user experience analytics
- Troubleshoot complex issues involving browser compatibility, rendering performance, or API integration bottlenecks
Mentorship & Leadership:
- Mentor front-end and full-stack engineers through design reviews, pair programming, and technical guidance
- Influence technical direction across multiple product teams and establish front-end best practices organization-wide
- Lead by example with high-quality code contributions and architectural decision-making
About You:
