Senior Frontend Software Engineer

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.
