The Role
As a Frontend Engineer, you will design and own the frontend architecture of large-scale products, optimizing performance, accessibility, and scalability while leading technical initiatives and mentoring engineers.
Summary Generated by Built In

Emergent builds autonomous coding agents that replace traditional software development by generating, testing, and deploying production applications directly from plain-language intent. Our systems run in production at global scale and are used to build millions of real applications.

Since public launch, Emergent has reached $100M ARR in 8 months. 6M+ users across 190+ countries have built 6.5M+ applications on Emergent. We've raised $100M+, backed by Khosla Ventures, SoftBank, Google, Lightspeed, Prosus, Together, and Y Combinator.

We're solving the hard part of AI-driven software creation: correctness, reliability, security, and scale in real production systems. The team is built by repeat founders, Olympiad medalists, IIT & IIM alumni, and leaders from Google, Amazon, and Dropbox.

We're hiring builders who want ownership, speed, and impact at global scale.

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 to 8 years of frontend engineering experience with deep React.js and TypeScript expertise
  • Strong background in architecting large-scale, distributed, modular frontend systems
  • Mastery of modern state management (Redux, Zustand, Recoil, React Query, or similar)
  • Expert in JavaScript (ES6+), TypeScript, Web APIs, browser internals, and performance tuning
  • Strong with build tools (Webpack, Vite, Turborepo), bundling, and optimization strategies
  • 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, accessibility, 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

 

Benefits and Perks:

  • 401(k)
  • Health, dental, and vision insurance
  • Unlimited Paid Time Off: take the time you need to recharge and come back refreshed
  • Flexible Working Hours: work arrangements that fit your life and commitments

Let's build the future of software together.
