Frontend Systems Engineer

Frontend Systems Engineer Ship production-ready systems in days, not weeks. This is NOT a normal frontend role. We are looking for a high-speed frontend systems operator who can: • work under ambiguity • simplify complexity • make product decisions independently • move fast without overengineering Not a fit if you: • wait for perfect specs before starting • overengineer simple systems • think only in components, not systems • optimize architecture before product validation • need handholding for product decisions Strong fit if you can: • take incomplete Figma/product direction • ship production-ready systems very fast • prioritize business impact over architectural beauty • simplify systems under pressure • explain painful production mistakes honestly You should understand: • what breaks at scale • realtime/async frontend flows • performance bottlenecks • scalability tradeoffs • what NOT to build under deadlines Stack Next.js • React • TypeScript • Tailwind Strong plus: • Zustand • SSR/ISR • WebSockets • realtime systems • monorepos • performance optimization AI-native mindset required You already use: • Claude • Cursor • Copilot • AI workflows Not occasionally. Operationally. We value engineers who use AI to: • remove boilerplate • accelerate delivery • improve debugging and workflows Our benchmark • 2–3 days from design to live • fast iteration without unnecessary complexity • shipping critical paths first • honest escalation when something blocks delivery If an edge case turns a 2-day task into a 5-day task: we expect immediate escalation with facts — not silence. Best fit usually has • startup/founding engineer experience • frontend + systems overlap • backend awareness • strong product ownership • high autonomy Success in this role You make the company: • faster • simpler • more scalable • less blocked by ambiguity Not: “more architecturally beautiful.” Apply with • portfolio/live projects • GitHub • fastest project shipped • exact timeline • what you intentionally cut to move faster • one painful production lesson you learned Remote.
