Sr. Software Engineer Frontend

Frontend Engineer – Austin, TX (Hybrid) Schedule: Full-time | Hybrid (2-3 days in office) Work Authorization Notice: At this time, we are unable to provide immigration sponsorship for this position. Candidates must have current, unrestricted authorization to work in the country where the role is based. About the Role Togetherwork is seeking a Frontend Engineer to incrementally modernize the user interfaces of 20+ SaaS products across a polyglot stack while keeping everything running for customers. Not prototyping - replacing live, production legacy UIs. You will work from Figma designs, leverage AI coding tools to accelerate implementation, and own the full journey from design handoff to backend integration. You are expected to use AI tools as a core part of your daily workflow. What You'll Do Legacy UI Modernization: Incrementally replace server-rendered UIs with modern React components without breaking what is currently running. You understand the strangler pattern, know when to wrap versus replace, and scope modernization work into small shippable increments that are safe to deploy. Figma to Production: Take Figma designs from handoff to production-ready React components using AI tools to accelerate code generation, then apply the judgment to validate, refine, and ship. You know the difference between AI output that is ready to ship and output that needs to be reworked. Backend Integration: Identify when a legacy server-rendered product needs API decoupling before the frontend can be modernized, and work with backend engineers to solve that problem. AI-Augmented Development: Use AI models as active tools in your daily workflow, accelerating Figma-to-code implementation. You evaluate AI output critically and know when to accept, refine, or rewrite. Quality and Stability: Implement feature flags for UI changes so rollback is always possible. Write unit and visual regression tests to catch when modernized components affect surrounding legacy UI. Own performance benchmarking before and after modernization to demonstrate measurable improvement. Cross-Functional Collaboration: Work directly with designers on Figma handoff, product managers on scope and priority, and backend engineers on API contracts. Communicate modernization trade-offs clearly. What You'll Bring 5+ years of experience as a frontend engineer Strong proficiency in React, TypeScript, JavaScript, and CSS Hands‑on experience modernizing at least one server‑rendered legacy stack: PHP, Ruby on Rails, or .NET Experience with incremental modernization patterns Demonstrated use of AI coding tools to ship production frontend code Figma handoff experience Backend integration experience with understanding of API decoupling requirements Proven frontend testing proficiency Experience with feature flagging for safe incremental UI rollout Preferred Qualifications Experience across multiple products or a platform engineering team simultaneously Accessibility awareness (WCAG compliance) especially when modernizing legacy UI Component library experience Benefits Medical, dental, and vision insurance options 100% Employer paid short/long term disability Basic Life 401(k) option with 100% company match up to 4% Flexible paid personal/vacation time built on mutual trust and accountability 10 sick days annually 10 company paid holidays 6 weeks paid parental leave Pet Insurance Medical Travel Benefits Infertility Benefits Teladoc Employee Assistance Program Wellness Benefits & Engagement Platform Inclusion and Diversity Togetherwork is an Equal Employment Opportunity Employer.
