ABOUT THE COMPANY America is under sustained cyber attack. Our adversaries infiltrate our networks, steal our IP, and degrade the digital infrastructure that modern life runs on. They’ve learned—correctly—that those attacks rarely produce consequences. Twenty was founded to change that, by making our adversaries think twice before they attack us. Our vision is American and allied primacy in cyberspace—a future where they cannot contest us, deterrence is assured, and the free world remains secure. Founded in 2024, Twenty Technologies (www.twenty.io http://www.twenty.io) industrializes offensive cyber operations for the U.S. and its allies. Headquartered in Arlington, Virginia, Twenty has raised $138M from Accel, Caffeinated Capital, Friends & Family Capital, Point72 Ventures, General Catalyst, and In-Q-Tel.   THE ROLE You'll be a high-output engineer building mission-critical operator experiences — implementing complex, high-performance interfaces that visualize real-time cyber operation data with speed and precision. You'll contribute meaningfully to frontend architecture and design decisions, own significant features end-to-end, and raise the quality of the codebase around you. You'll work closely with other frontend engineers and cross-functional partners across backend, product, design, and operations to ship capabilities that must work reliably in both cloud and on-premises environments. WHO YOU ARE - You care about building software that has real-world impact in high-stakes environments. - You write clean, precise, and well-tested code and hold yourself to that standard without being asked. - You think carefully about performance, reliability, accessibility, and maintainability as you build. - You make sound tradeoffs under constraints and communicate them clearly to teammates. - You're drawn to complex data problems and enjoy turning them into interfaces that help users act quickly. - You take ownership of your work end-to-end — from design review to production — and take pride in delivering on your commitments. - You default to secure engineering practices and treat trust, safety, and correctness as non-negotiable. WHAT YOU'LL DO - Build sophisticated React/TypeScript features and components that operate reliably at scale. - Implement real-time UI experiences for complex cyber operation data, optimizing for speed and clarity. - Contribute to frontend architecture and design decisions alongside your teammates. - Build and maintain interactive visualization components (e.g., graphs, timelines, streaming views). - Write and maintain automated tests across unit, integration, and end-to-end layers. - Participate actively in code review — giving and receiving feedback that raises the quality bar. - Identify and address performance issues, technical debt, and reliability gaps proactively. - Collaborate with design, product, backend, and operations to deliver well-integrated features. - Support engineers through pairing and practical feedback on their work. QUALIFICATIONS MUST HAVE - You have 5–8 years of professional frontend software development experience. - You have strong, production-tested expertise in React.js and TypeScript. - You have solid command of modern web fundamentals (JavaScript/TypeScript, HTML, CSS). - You have experience building and shipping features for performance at scale (profiling, optimization, rendering strategies). - You have hands-on experience with automated testing frameworks (e.g., Vitest, React Testing Library, Playwright or Cypress). - You have experience with state management patterns and libraries (e.g., Redux, Zustand, or React Query). - You have experience with modern build tooling (e.g., Vite or Webpack) and CI/CD pipelines. - You collaborate effectively with product and design to deliver high-quality UX. - You have strong command of Git in a professional engineering environment, including branch wor
