About this Role
As a Senior Frontend Software Engineer, you work with minimal guidance to design, build, and evolve complex, accessible, performant, and maintainable user-facing applications. You apply deep expertise in frontend architecture and modern web development to translate user needs, design systems, and product requirements into reliable, intuitive digital experiences.
You collaborate with the team to break down ambiguous or complex goals into concrete, feasible steps that align with and inform wider system strategy. Senior engineers do not always have formal management or lead responsibilities, but an interest in teaching and coaching is essential.

• Define and evolve frontend architecture, including component boundaries, application structure, routing, state management, data fetching, and client-side error handling.

• Drive improvements in frontend code quality, testing practices, and development standards across the team

• Use browser developer tools, automated checks, logging, and monitoring to diagnose issues, investigate production defects, and improve application reliability.

• Mentor engineers, review code and technical designs, and contribute to team growth and technical direction

• Collaborate to break down ambiguous or complex goals into concrete, feasible steps and communicate frontend risks, dependencies, and tradeoffs to relevant stakeholders.
