Job description

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

Some of the world's largest companies and their law firms use Harvey’s AI capabilities to deliver world-class client services at unprecedented scale and efficiency. Harvey allows high-performing professionals to gain deep domain knowledge faster, understand the big picture, and tackle more complex challenges in less time.

Security is at the heart of what we do. Our customers trust us with their most sensitive data, and we take that responsibility seriously. As part of our team, you’ll help us maintain a secure, trustworthy, and compliant platform—an essential foundation for everything we build.

As a Staff Infrastructure Security Engineer, you’ll set the technical direction for secure-by-default infrastructure security across Harvey’s platform, establishing the patterns and standards the broader engineering organization builds on. This includes designing and implementing processes and technologies for least privilege, isolating different components, managing attack surface, and implementing layers of tenant isolation on our multi-tenant SaaS offering. You’ll also create frameworks and repeatable patterns that enable our research and engineering teams to move quickly and independently—without sacrificing security.

Our security program at Harvey is growing fast, so this is an incredible opportunity to get in at the beginning and shape the future of what Security at Harvey looks like. This team approaches security with an engineering-first mindset with our customers front and center to everything we do.

What You'll Do

• Incorporate secure design principles into our cloud architecture.
• Establish reusable security patterns, standards, and guardrails that enable product and platform teams to build securely by default
• Develop isolation mechanisms (e.g. sandboxing) in collaboration with our product engineering team
• Review security-critical configuration changes and act as Codeowner for security-critical parts of our cloud configurations (everything is IaC)
• Partner with Engineering and Product teams to:
• Manage risks and vulnerabilities in our Cloud environment.
• Translate security requirements into concrete engineering investments
• Define infrastructure security architecture and multi-quarter roadmaps
• Mentor and develop other security engineers on the team, raising the overall technical bar

What You Have

• 8+ years experience in Security Engineering and/or Software Engineering
• Demonstrated experience writing high-quality software, building production-grade infrastructure and raising the security bar across engineering teams.
• Strong fundamentals in networking, operating systems, and cryptographic protocols
• In-depth knowledge of Kubernetes, common misconfigurations, and privilege escalation vectors
• Demonstrated ability to find weaknesses (e.g. privilege escalation) in real-world cloud environments
• Experience applying security best practices in cloud environments (AWS, Azure, or Google Cloud)
• Track record of driving cross-functional security initiatives and influencing engineering decisions across teams
• Experience setting security standards and best practices at an organizational scale
• (No experience with generative AI or legal required)

Bonus

• Familiarity with large-scale Infrastructure as Code (IaC) deployments
• Familiarity with Kubernetes Admission Controllers and policy enforcement
• Exposure to multi-cloud environments
