Role Overview

As a Senior Software Engineer on the Security Engineering team at Harvey, you'll build and operate the foundational security services every other engineer at Harvey depends on: encryption and key management, public key infrastructure (PKI), secrets management, identity and access, and the tooling that makes the secure path the fast path. You'll design these systems, write the code, run them in production, and own the results. Agentic systems make this harder than it is at a typical SaaS company: when an AI agent acts on a user's behalf against their most sensitive documents, protecting data, credentials, and execution boundaries becomes essential to every workflow.

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 customers' data is greatest, rather than where a framework tells us to.

What You'll Do

• Design, build, and operate shared services for encryption, key management, and secure storage, partnering with Product and Infrastructure teams to protect sensitive data

• Build PKI and certificate lifecycle automation, including issuance, renewal, revocation, and trust rotation

• Build secrets management workflows that discover exposed credentials, enable secure storage and delivery, automate rotation, and support rapid revocation

• Build secure-by-default libraries and self-service tooling for data protection and identity and access, making shared security controls easy for engineering teams to adopt

• Build reusable tooling for code, dependency, and secret scanning, CI/CD enforcement, and remediation, including infrastructure to safely run and observe security agents

• Take these systems from greenfield to production-grade: define the architecture, ship it, instrument it, and own its reliability

• Contribute to incident response and drive technical mitigation when security issues surface

• Raise the security bar across engineering through design reviews, code reviews, and technical mentorship

What You Have

• 5+ years of software engineering experience with a track record of shipping and operating production services

• Hands-on experience designing, building, and operating security infrastructure in one or more areas such as PKI, encryption and key management, secrets management, secure software delivery, or identity and access

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

• Strong programming skills and a willingness to work across the stack and across unfamiliar domains

• Fluency building and maintaining production services with agentic coding tools (Claude Code, Codex, or similar) — you know how to get real leverage from them and where they need supervision

• Experience with cloud infrastructure (Azure, GCP, or AWS) and modern distributed system patterns

• Demonstrated ability to turn security requirements into scalable engineering solutions rather than manual process

• Strong communication and collaboration skills; you can influence engineering teams without formal authority

Nice to Have

• Experience building security platforms or programs at hyper-growth startups

• Background in developer platform or infrastructure engineering

• Experience applying cryptography in production through established libraries, envelope encryption, cloud key management services (KMS), or hardware security modules (HSMs)

• Experience with PKI, TLS/mTLS, certificate lifecycle automation, or secrets rotation at scale

• Experience in highly regulated enterprise environments
