Senior Infrastructure Security Engineer

Job Overview

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. With 1500+ customers in 60+ countries, 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 Senior Infrastructure Security Engineer, you’ll design and build secure-by-default infrastructure that product teams can rely 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 driven by our collective offensive security experience: breaking into systems at other companies (in white-hat capacities), responding to real security incidents, and learning from other companies’ data breaches. We regularly conduct penetration tests and red team exercises. At the same time, we are all software engineers - contributing code daily and approaching security with an engineering-first mindset.

What You'll Do

• Incorporate secure design principles into our cloud architecture.


• 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)


• Audit our existing cloud environment for vulnerabilities


• Develop policies and procedures for the secure creation and operation of our cloud environments

What You Have

• 5+ years experience in Security Engineering, Software Engineering, or Site Reliability Engineering roles


• Demonstrated experience writing high-quality software and building production-grade infrastructure and raising the quality bar of 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)


• Experience owning and delivering complex security projects end-to-end as an individual contributor


• (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
