Conduct code reviews and promote frontend quality and best practices. Troubleshoot complex integration issues spanning browser APIs, backend services, and UI logic. Partner with product and design teams to drive UX improvements and evolve the design system. Stay current with emerging frontend technologies, browser APIs, and security best practices. COMPETENCIES Core expertise 5+ years building modern web applications with ReactJS (and ideally TypeScript). Proven experience developing and publishing browser extensions.
