Staff Infrastructure Security Engineer

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 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
• Define Harvey’s infrastructure security architecture and multi-year roadmap, translating security requirements into concrete engineering investments
• Establish reusable security patterns, standards, and guardrails that enable product and platform teams to build securely by default
• Mentor and develop other security engineers on the team, raising the overall technical bar
