About this role

Togetherwork is seeking a Frontend Engineer to incrementally modernize user interfaces of 20+ SaaS products across a polyglot stack. This means replacing live, production legacy UIs, not prototyping. You will own the full journey from Figma design handoff to backend integration.

Daily work involves taking Figma designs to production-ready React components using AI tools for acceleration. Evaluate AI output critically to validate, refine, and ship code. Identify API decoupling needs for legacy server-rendered products and collaborate with backend engineers.

Implement feature flags for safe UI changes, write unit and visual regression tests, and benchmark performance improvements. Work directly with designers on handoffs, product managers on priorities, and backend teams on API contracts. Communicate modernization trade-offs clearly.

Join a $250M recurring revenue SaaS business headquartered in Austin, TX, serving over 12 vertical markets. The company is customer-focused, execution-driven, and committed to operational excellence. Teams emphasize accountability, collaboration, and continuous improvement.
