• Translate product goals into scalable frontend architecture decisions, balancing speed, quality, and long-term maintainability
• Contribute meaningfully to the evolution of our React and Electron-based applications, improving shared libraries, platform capabilities, and system design
• Operate effectively in ambiguous problem spaces identifying risks, validating assumptions, and proactively de-risking solutions before they impact delivery
• Ensure the long-term health of the codebase by reducing technical debt, improving test coverage, and setting high standards for code quality and performance
• Collaborate closely with Product, Design, and Backend engineers to align on trade-offs, API contracts, and non-functional requirements such as performance, reliability, and security
• Proactively monitor, debug, and resolve production issues, contributing to observability, incident response, and post-mortems that strengthen our systems over time
• Mentor and support other engineers through thoughtful code reviews, technical guidance, and knowledge sharing that raises the bar for the entire team
• Maintain an active awareness of business priorities and customer impact, ensuring your technical decisions align with Weave’s broader product and company goals

• Experience leading technical implementation of production features end-to-end
• Strong understanding of frontend architecture, state management, and performance optimization
• Experience consuming and influencing RESTful APIs
• Familiarity with debugging complex production issues
• Experience writing automated tests (unit + integration + E2E)
• Experience building or maintaining Electron applications
• Deep knowledge of idiomatic TypeScript
• Experience with Storybook, Sentry, Playwright, Cypress (or similar tools)
• Experience performance benchmarking and tuning (e.g., measuring and improving load times, bundle size, or responsiveness)
• Understanding of how frontend systems are deployed, monitored, and operated in production
• Experience building secure, high-quality payment or form-heavy flows, including PCI-sensitive UIs (e.g., working with hosted payment iframes like Stripe)
• Exposure to server-side rendering concepts and an understanding of how server- and client-rendered content interact
