Corporate Security Engineer

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.

Some of the world's largest companies and their law firms use Harvey's AI to deliver world-class client services at unprecedented scale, entrusting Harvey with their most sensitive documents in the process.

This role joins Harvey's corporate security function, which secures the company's IT and business systems as Harvey grows rapidly, balancing risk with user experience while validating every assumption through threat modeling and real-world testing rather than relying on best practice alone.

It is a strong fit for someone at the intersection of security engineering and enterprise systems- someone who understands how data flows between SaaS applications, can pinpoint where security breaks down in complex integrations, and knows how to build controls that scale. Experience with eDiscovery workflows and legal holds is a meaningful differentiator given the nature of Harvey's customer base.

Enterprise Integrations & SaaS Security: Design, implement, and govern security controls for cross-application data flows, API integrations, OAuth connections, and third-party SaaS platforms. Own the security review lifecycle for new integrations and automate posture monitoring to catch drift early.

eDiscovery & Legal Hold Program: Continue to build and operate Harvey's legal hold infrastructure, including data preservation, collection workflows, and custodian management. Partner with Legal and Compliance to meet litigation readiness requirements across our collaboration and productivity stack.

IT & Business Systems Partnership: Provide security oversight across the SaaS application lifecycle — vendor onboarding assessments, ongoing configuration review, and decommissioning.

Endpoint Security: Support endpoint security policies and vulnerability management, ensuring endpoint telemetry feeds into detection and response workflows.

Security Detection & Response: Develop scripts and integrations that extend visibility across corporate systems, partnering with the Detection & Response team to surface signals from SaaS and business applications.

Demonstrated experience securing enterprise SaaS environments, including integration security, API token management, OAuth governance, and cross-application data flow risk — with working knowledge of authentication/authorization standards (SAML, OIDC, SCIM, X.509) and the ability to debug real-world integration failures.
