Frontend Engineer

Backed by Lightspeed, Y Combinator, Together Fund, and Prosus, Emergent is reimagining how software gets built. 

Our vision is to democratize development, enabling anyone with an idea to become a creator and making software accessible to a billion people worldwide. Our autonomous coding agents turn plain-language ideas into fully functional applications, tested, version-controlled, and deployable in minutes. What once took weeks now happens with a single click. 

Headquartered in San Francisco, we’re led by repeat entrepreneurs with a proven track record of building successful startups, joined by a world-class team of Olympiad medalists, IIT & IIM alumni, and veterans from Google, Amazon, and Dropbox. Together, we’re building at the frontier of AI and systems engineering, shipping daily and setting new standards for AI-driven development. 

In just 5 months, we scaled to $25M ARR, shipped 3M+ Apps, with 2.5M users across 180+ countries, making us one of the fastest-growing AI startups in the world. 

What You’ll Do

• Define and own the frontend architectural vision for complex, high-scale products
• Design scalable component systems, UI frameworks, and internal tooling
• Translate product requirements and Figma designs into robust technical architecture
• Lead performance optimization, accessibility, security, and scalability initiatives
• Break down complex problems, propose long-term technical strategies, and influence roadmap
• Build reusable libraries, design systems, and internal packages for engineering efficiency
• Review critical code paths, guide engineering best practices, and maintain technical excellence
• Work closely with Product, Design, and Backend to shape end-to-end solutions
• Mentor and upskill senior engineers, enabling them to operate at an architect level

What We’re Looking For

• 4–8 years of frontend engineering experience with deep React.js + TypeScript expertise

• Ability to design UI frameworks, component libraries, and cross-platform solutions
• Solid understanding of REST, GraphQL, caching, and client-side data architecture
• Strong debugging skills and experience resolving production-scale issues
• Experience with automated testing (Jest, RTL, Cypress) and CI/CD workflows

Good to Have

• Experience with Next.js, micro-frontends, or SSR architectures
• Worked with design systems (Storybook, MUI, Chakra, Radix)
• Contribution to open-source projects or internal engineering frameworks
• Knowledge of web security, a11y, and SEO optimization
• Background in mentoring engineering teams or owning cross-functional initiatives

Why Join Us?

• Architect the core frontend foundation of a product used globally
• Work with world-class engineers building the future of AI-driven development
• Impact product velocity, quality, and engineering culture at scale
• Flexible, high-ownership, remote-friendly environment
• Learn fast, ship faster, and influence the next decade of software creation
