Why Harvey
At Harvey, we’re transforming how legal and professional services operate. By combining frontier agentic AI, an enterprise-grade platform, and deep domain expertise, we’re reshaping how critical knowledge work gets done for decades to come.
This is a rare chance to help build a generational company at a true inflection point. We have strong product-market fit and world-class investor support. We’re scaling fast and defining a new category in real time. The work is ambitious, the bar is high, and the opportunity for growth — personal, professional, and financial — is unmatched.
Our team moves fast, takes ownership, and is deeply committed to the mission — operating with intensity, staying close to our customers, and pushing each other for excellence. We live by three values: Decisiveness, Simplicity, and Job's Not Finished. We act quickly on clear judgment over perfect information, we believe simplicity is what scales, and we're never satisfied with where we are. If you want to do the best work of your career alongside people who share that drive, we'd love to build with you.
At Harvey, the future of professional services is being written today — and we’re just getting started.
Role Overview
We’re looking for experienced frontend engineers to help build and evolve Harvey’s frontend platform—the systems, tools, and abstractions that enable our engineering team to ship high-quality product experiences quickly and consistently.
This team focuses on developer experience, performance, reliability, and scalability across our frontend stack. Rather than building one-off product features, you’ll create shared foundations that power all of Harvey’s user-facing applications.
This is a high-impact role with broad scope across the engineering organization. You’ll work closely with product engineers, design, and infrastructure teams to define and drive the future of frontend development at Harvey.
What You'll Do
- Build and evolve shared frontend infrastructure, including our design system and developer tooling
- Contribute to and evolve frontend architecture for scalability and performance
- Improve developer experience and engineering velocity
- Improve application performance and reliability
- Partner with product teams to drive adoption of platform systems
- Identify and reduce friction across the development lifecycle
What You Have
- Strong experience working on large-scale frontend systems or platform-level infrastructure
- Ability to think in systems and abstractions, not just features
- A track record of improving developer experience or engineering velocity
- Experience influencing technical decisions across teams or driving adoption of shared systems
