Senior 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 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.
What You'll Do
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
What You Have
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
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 with SCIM, OIDC/SAML, policy engines (OPA, Cedar, Zanzibar-style systems), or hardware-backed credentials
Experience in highly regulated enterprise environments
Compensation
$220,000 - $330,000 USD
