Senior Software Engineer, Security at Harvey · LumiJobs

Responsibilities

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: identity and access management, secrets and privileged 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, identity and authorization stop being solved problems.
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.
Design, build, and operate Harvey's core security services — authentication, authorization, access governance, secrets management, and privileged access — across workforce, infrastructure, and production environments
Own Harvey's identity infrastructure end-to-end, including SSO, SCIM, and the fine-grained authorization our enterprise customers require
Build secure-by-default libraries, paved-road abstractions, and self-service tooling so engineering teams can identify, remediate, and prevent security issues without waiting on us
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
5+ years of software engineering experience with a track record of shipping and operating production services
Hands-on experience building security infrastructure — IAM, authn/authz, secrets management, or privileged 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
