We're transforming how enterprises build software, turning enterprise requirements into enterprise grade code with an agentic software development platform that can autonomously execute 80% of the quantum of software development work. We're backed by multiple tier 1 investors, and have proven success as founders of previous start-ups.\nOur Culture\nWho we are:\nLed by two pioneering co-founders we are one of the fastest growing companies in the U.S., creating our own category of enterprise autonomous software development. We automate thousands of hours of software development for our customers, which includes strong representation within the Fortune 500.\nHow we work:\nWe move Blitzy Fast: Time is both our company’s and our clients’ most precious asset. We move quickly and decisively to innovate internally and deliver exceptional software externally.\n\nChampionship Mindset: We operate like a professional sports team.

You’ll work directly with our CTO to build sophisticated, responsive interfaces that make complex AI capabilities accessible to enterprise developers. This is a hands-on technical leadership role where you’ll architect our frontend systems, establish engineering best practices, and mentor junior engineers as we scale.\nYou’ll be the frontend technical authority-making critical architectural decisions, building new platform features, refactoring existing systems, and defining how we approach frontend engineering at Blitzy. You’re equally comfortable debugging a complex state management issue, architecting a component library from scratch, or mentoring a junior engineer through their first major feature.\nResponsibilities\nOwn frontend architecture and technical decision-making for our core platform.\n\nRefactor existing frontend systems to improve performance and maintainability.\n\nBuild new platform features that showcase our AI capabilities to enterprise users.\n\nEstablish component library and design system foundations.\n\nSet up testing frameworks and CI/CD pipelines for frontend.\n\nDefine code review processes and engineering standards.\n\nMentor and provide technical guidance to junior frontend engineers.\n\nOptimize performance and build monitoring systems.\n\nImprove frontend infrastructure and build tooling.\n\nCollaborate with cross function stakeholders on API design and integration patterns.\n\nWrite technical documentation and shape onboarding processes.\n\nScale the frontend engineering team and practices.\n\nDefine frontend engineering hiring standards and interview processes.\n\nContribute to product and technical strategy discussions.\n\nBuild advanced features like real-time collaboration, AI-powered UIs, and developer tools.\n\nQualifications\n10+ years of frontend development experience with a proven track record of building complex, production-grade applications.\n\nExpert-level knowledge of modern JavaScript/TypeScript with deep understanding of language features, patterns, and best practices.\n\nDeep expertise in React.js and its ecosystem including hooks, context, performance optimization, and modern patterns.\n\nStrong understanding of state management (Redux, MobX, Zustand, or similar) and when to apply different patterns.\n\nExperience with modern build tools (Webpack, Vite, esbuild, etc.) and their configuration.\n\nProven ability to architect scalable frontend systems that handle complexity while remaining maintainable.\n\nExperience with responsive design and cross-browser compatibility, ensuring consistent experiences across devices.\n\nStrong understanding of web performance optimization including bundle size, rendering performance, and Core Web Vitals.\n\nExperience with frontend testing frameworks and methodologies (Jest, React Testing Library, Playwright, Cypress).\n\nTrack record of technical leadership including mentoring, code reviews, and establishing engineering standards.\n\n Compensation: $215,000 - $290,000 + Bonus + Equity\nBlitzy is an equal opportunity employer committed to building a diverse and inclusive team.
