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

Harvey's Custom Solutions team builds tailored AI tools for leading strategic customers. The team scopes, designs and implements custom agents, playbooks and prompts to address high-priority use cases. Each solution is built around a customer's specific needs and stored in its Harvey instance for scalable access across the organization.

Team members have opportunities to travel onsite and build relationships with senior stakeholders to support the rollout of these tools. They also partner with Harvey's Go-to-Market and Product teams to advance the platform by gathering feedback, surfacing opportunities and piloting features.

What You'll Do

  • Establish a clear understanding of Harvey's platform and the process for building solutions (you're not expected to be a platform expert on day one, but you should be interested in becoming one).
  • Scope, design and build custom agents, playbooks and prompts for key strategic customers.
  • Build strong relationships with senior stakeholders to understand their requirements, map their processes and turn needs into working solutions.
  • Prototype, test and iterate, including piloting Harvey features prior to general release.
  • Communicate market feedback to Product and Engineering, surfacing the opportunities for enhancements that will be most impactful.
  • Partner with Harvey's other Legal Engineering and Go-to-Market teams to deliver measurable growth.
  • Create and maintain reusable assets, capturing best practices to speed up future deployments.

What You Have

  • Qualified lawyer in England & Wales
  • 3+ years of experience as a practicing lawyer at a top-tier firm and/or in-house legal team.
  • Curiosity about testing various approaches, evaluating deliverable quality and optimizing for customer outcomes and experience.
  • Strong communication skills and a track record of partnering with senior stakeholders to drive results.
  • Interest in driving positive change in the legal industry through AI.
  • Experience using AI tools in legal practice is a plus.
