Software Engineer, Security

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

As a Software Engineer on the Security Engineering team at Harvey, you'll build and operate foundational security services for both our customer-facing product and the internal systems our workforce depends on: encryption and key management, public key infrastructure (PKI), secrets management, and shared controls for identity, secure software delivery, and agent execution.

You'll turn security needs into production systems and own the reliability and security of what you build, working closely with engineers and partner teams along the way. Attackers increasingly operate at agent speed, so we’re building defenses that can keep pace.

Security at Harvey is an engineering discipline, not a gatekeeper function. We build platforms and libraries that make it hard for engineers to get security wrong, and we measure ourselves on adoption and outcomes rather than tickets filed. Our program is informed by risk: we invest where the actual exposure to our most sensitive data and resources is greatest, rather than where a framework tells us to.

What You'll Do

• Build and operate services for encryption, key management, and secure storage across product and infrastructure systems, working closely with partner teams
• Implement and improve PKI and secrets management workflows, including certificate renewal, secure credential delivery, rotation, and revocation
• Build identity controls, sandboxes, and safety harnesses that let services and AI agents operate with least privilege, constrained actions, clear auditability, and effective monitoring
• Create secure-by-default libraries and self-service tooling that make encryption, secrets handling, and other shared security controls easy to adopt
• Build code, dependency, and secret scanning integrations, CI/CD controls, and agentic workflows that automate security triage, remediation, and evidence collection
• Take security systems from design through production, accounting for trust boundaries, attacker paths, and operational failure modes while owning their reliability and security
• Share an on-call rotation for Harvey’s mission-critical security services, contribute to incident response, and raise the engineering bar through design reviews, code reviews, and clear documentation

What You Have

2+ years of software engineering experience, including experience shipping and operating production services

Experience building or contributing to security infrastructure in one or more areas such as encryption and key management, PKI, secrets management, secure software delivery, or identity and access

• Strong programming, debugging, testing, and problem-solving skills, with the ability to work across unfamiliar systems and domains
• Experience with cloud infrastructure such as Microsoft Azure, Google Cloud Platform, or Amazon Web Services and familiarity with modern distributed-system patterns
• A track record of translating security requirements into maintainable, automated systems

Experience using agentic coding tools and creating workflows that automate repetitive security work, with the judgment to review their output critically and measure whether they improve security outcomes

Clear communication and collaboration skills, including the ability to explain technical risks, decisions, and tradeoffs to engineering partners

Working knowledge of common vulnerability classes and the ability to reason about how a system fails under an attacker, not just under load

Nice to Have

• Experience building security infrastructure at a fast-growing company
• Familiarity with applied cryptography, such as using established cryptographic libraries, encryption APIs, or cloud key management services (KMS)
• Experience with TLS/mTLS, certificate lifecycle automation, or secrets management platforms
• Experience securing agentic or AI-powered systems, especially systems that act on behalf of users against sensitive data
• Experience working in a highly regulated enterprise environment
