• Collaborate with product managers, designers, and backend engineers to translate complex requirements into intuitive user experiences. • Design, build and evolve scalable, high-performance frontend web applications • Participate in code reviews, share best practices, and help maintain high engineering standards within the frontend team. • Work closely with DevOps to streamline CI/CD pipelines, improve deployment reliability, and enhance observability through metrics and monitoring tools. • Own features end-to-end such as requirement refinement, implementation, testing, and delivery. Optimize frontend performance, focusing on loading times, rendering speed, and bundle efficiency. • Ensure cross-browser and multi-device compatibility while meeting accessibility (a11y) and usability standards. • Contribute to the modernization, refactoring, and continuous performance improvements to keep the platform scalable, maintainable, and aligned with product goals. • Contribute and enforce engineering best practices across coding, documentation, testing, and review processes. • Ensure strong automated test coverage and reliable CI/CD workflows that reduce manual effort and improve delivery predictability. • Own operational excellence, including incident response, root-cause analysis, and long-term reliability improvements. • Advocate for scalability, performance, security, and observability across the platform’s architecture and tooling. • Identify technical risks, estimate complexity, and communicate trade-offs to leadership and stakeholders.

• You'll be part of a senior engineering team responsible for stabilizing and evolving UE Advocacy. Depending on focus area, you may work in one of three lanes: - **Re-architecture.** Port modules from the legacy Express API to the new Hono API with full integration test coverage. Decompose large React components (3,000-5,000 LOC pages) and convert .jsx to strict-mode .tsx. Improve frontend performance — bundle splitting, dynamic imports, mobile-first defensive coding, embed reliability. Harden data integrity by introducing real state machines and typed enums. - **Feature work.** Build new customer-facing features behind feature flags with canary rollouts, against PM-written acceptance criteria. Follow established backend patterns and frontend conventions exactly — we have reference modules for a reason. - **Bug triage and fixes.** Investigate customer-reported bugs using New Relic traces, structured logs, and database queries. Reproduce, fix, and add tests to prevent regression. Most bugs live in legacy code; finding them is a code-archaeology skill. Across all three lanes, you will: • Write clean, maintainable, well-tested code following established patterns • Conduct thoughtful peer code reviews and respond constructively to the same • Use automated code review (Macroscope), automated tests (Bun, Vitest, Playwright), and canary deploys as your safety net — not manual full-app QA • Troubleshoot production issues using New Relic, structured logs, and direct database queries

• Develop new features for web platforms and actively implement components and patterns defined by our Design System. • Build high-complexity screens and flows, ensuring responsive and fluid designs. • Code modular components for the Design System following established standards. • Ensure visual, semantic, and functional consistency across different browsers (cross-browser). • Write unit, integration, and visual tests. • Work with the Azure DevOps CI/CD pipeline for publishing and fixing builds.
