It makes for a happier and more productive team. ## About the Role We’re looking for a Senior Frontend Engineer to join our founding team and lead our frontend engineering efforts. 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. You’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. ## Responsibilities - Own frontend architecture and technical decision-making for our core platform. - Refactor existing frontend systems to improve performance and maintainability. - Build new platform features that showcase our AI capabilities to enterprise users. - Establish component library and design system foundations. - Set up testing frameworks and CI/CD pipelines for frontend. - Define code review processes and engineering standards. - Mentor and provide technical guidance to junior frontend engineers. - Optimize performance and build monitoring systems. - Improve frontend infrastructure and build tooling. - Collaborate with cross function stakeholders on API design and integration patterns. - Write technical documentation and shape onboarding processes. - Scale the frontend engineering team and practices. - Define frontend engineering hiring standards and interview processes. - Contribute to product and technical strategy discussions. - Build advanced features like real-time collaboration, AI-powered UIs, and developer tools. ## Qualifications - 10+ years of frontend development experience with a proven track record of building complex, production-grade applications. - Expert-level knowledge of modern JavaScript/TypeScript with deep understanding of language features, patterns, and best practices. - Deep expertise in React.js and its ecosystem including hooks, context, performance optimization, and modern patterns. - Strong understanding of state management (Redux, MobX, Zustand, or similar) and when to apply different patterns. - Experience with modern build tools (Webpack, Vite, esbuild, etc.) and their configuration. - Proven ability to architect scalable frontend systems that handle complexity while remaining maintainable. - Experience with responsive design and cross-browser compatibility, ensuring consistent experiences across devices. - Strong understanding of web performance optimization including bundle size, rendering performance, and Core Web Vitals. - Experience with frontend testing frameworks and methodologies (Jest, React Testing Library, Playwright, Cypress). - Track record of technical leadership including mentoring, code reviews, and establishing engineering standards. Salary Range: $150,000 - $185,000 + Bonus + Equity Blitzy is an equal opportunity employer committed to building a diverse and inclusive team. We believe different perspectives make us stronger.
