• Develop user-facing features with React (TypeScript/JavaScript), following USWDS design patterns and VA API/FHIR standards where applicable
• Write and maintain 100% automated test coverage (unit, integration, functional, load, and accessibility) for all delivered features
• Integrate with VA APIs and backend services to ensure accurate, secure data rendering and discoverability via the Lighthouse API Hub
• Support the migration and retirement of legacy systems, ensuring continuity of content and functionality
• Contribute to full-stack development across healthcare features (e.g., secure messaging, medical records, medications) with a focus on interoperability and user-centered design
• Monitor and triage application performance issues daily using tools like Datadog, and respond to incidents according to VA-defined severity levels
• Prevent and resolve silent failures through robust error handling, user notification mechanisms, and backend transaction validation
• Participate in pair programming, peer reviews, and blameless post-mortems, incorporating learnings and promoting engineering excellence
• Continuously integrate and deploy code using VA Platform tooling, CI/CD pipelines, and reusable infrastructure components across VA.gov and VA Mobile

• Ability to leverage AI-assisted development tools (for this project, CoPilot specifically) to responsibly to accelerate delivery, improve code quality, and support experimentation per evolving client AI tooling expectations
• Hands‑on experience with CI/CD pipelines, automated testing, and cloud infrastructure (AWS, Docker, Kubernetes, or similar)
• Experience with measurement and monitoring tools (e.g., Datadog) and a strong understanding of application observability
• Familiarity with secure development best practices and Zero Trust principles; ability to safeguard sensitive data while working in an open‑source environment
