Weave is building an operating system for small healthcare practices, powering communication, payments, and AI-driven experiences for thousands of businesses and millions of patients.
As a Senior Frontend Engineer, you will own 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. You'll translate product goals into scalable frontend architecture decisions, balancing speed, quality, and long-term maintainability. You'll contribute meaningfully to the evolution of React and Electron-based applications, improving shared libraries, platform capabilities, and system design.
You will operate effectively in ambiguous problem spaces, identifying risks, validating assumptions, and proactively de-risking solutions before they impact delivery. You'll ensure the long-term health of the codebase by reducing technical debt, improving test coverage, and setting high standards for code quality and performance. Collaboration with Product, Design, and Backend engineers is essential to align on trade-offs, API contracts, and non-functional requirements such as performance, reliability, and security.
You will proactively monitor, debug, and resolve production issues, contributing to observability, incident response, and post-mortems that strengthen systems over time. You'll mentor and support other engineers through thoughtful code reviews, technical guidance, and knowledge sharing that raises the bar for the entire team. Maintaining an active awareness of business priorities and customer impact ensures your technical decisions align with Weave's broader product and company goals.
This role is ideal for engineers who want real ownership, care deeply about craft and performance, and thrive in environments where goals are clear but the path forward requires thought, collaboration, and leadership.
