frontend engineer

Want to build product experiences for AI agents that actually understand how companies operate?

This team is tackling a core limitation in enterprise AI. Models are general, but workflows are not. They're building agents that learn how processes really run, then execute them. This is not surface-level UI work, you're building the interface layer to systems that directly operate inside real business workflows.

They're a Series A company backed by Sequoia, with a deeply technical team across engineering and AI. As an early frontend engineer, you won't just build features, you'll shape how the product feels, how it's structured, and how other engineers build on top of it.

You'll work primarily in TypeScript and React, building high-quality, user-facing experiences that sit on top of complex AI systems. Strong typing, clean abstractions, and thoughtful API design matter here. This is a team that values well-modelled systems over quick fixes.

There's no separation between building and shipping. You'll take ideas from concept to production, owning decisions across architecture, UX, and implementation. You'll work closely with design, contributing to interface decisions and helping define how users interact with agent-driven workflows.

You'll also have real influence on frontend architecture, tooling, and patterns. Whether that's building a component library, shaping state management decisions, or improving how the frontend integrates with backend systems, your decisions will compound as the team scales.

What you'll focus on:

• Building production-grade frontend applications using TypeScript and React
• Designing and contributing to frontend architecture, patterns, and component systems
• Collaborating closely with design to shape UX and interface decisions
• Owning features end-to-end, from scoping through to deployment
• Debugging across the stack, including tracing issues into API and backend layers

• Strong experience with TypeScript, with a focus on well-typed, maintainable code
• Solid React fundamentals, building scalable and performant interfaces
• Experience designing APIs, data models, or internal tooling that improves developer workflows
• Good product and interaction judgement, comfortable working closely with design
• Comfort owning ambiguous problems and turning them into clear, deliverable solutions

You'll likely have around 3+ years in software engineering, but what matters more is how you think about systems. If you enjoy building from scratch, care about clean abstractions, and take pride in code that other engineers enjoy working with, you'll fit well here.

Bonus if you've worked with Next.js, built design systems, or developed libraries and SDKs. But strong fundamentals in React and TypeScript are the priority.

This is a frontend-focused role, but you'll be expected to understand the wider system. You should be comfortable debugging issues beyond the UI when needed.

If you're motivated by building thoughtful systems, not just shipping features, this is the kind of environment where your work compounds over time.
