Senior Frontend Software Engineer at Weave

At Weave, we’re building the operating system for small healthcare practices powering communication, payments, and now AI-driven experiences for thousands of businesses and millions of patients. As a Senior Frontend Engineer, you won’t just build UI components. You’ll shape how customers experience our product every day. This is a role for engineers who want real ownership who care deeply about craft, performance, and long-term system health and who thrive in environments where the goals are clear but the path forward requires thought, collaboration, and leadership. Our ideal candidate takes initiative without waiting for direction. They care deeply about customer impact as much as clear architecture and enjoy resolving ambiguity and influencing technical decisions. We’re excited to bring in talent that wants to elevate engineers around them. If you’re excited by meaningful ownership, technical influence, and building products that power real-world businesses you’ll thrive at Weave. What you will own - Lead the end-to-end technical execution of small to medium initiatives, from shaping requirements and writing technical design proposals through implementation, testing, and production release. - 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. What You Will Need to Accomplish the Job - 5+ years building modern web applications using TypeScript/JavaScript. - 3+ years working with React (or similar modern frontend framework). - 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). What will make us love you - 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.
