Senior Security Engineer, Identity and Access Management Remote Location: San Francisco, California, U.S. • Seattle, Washington, U.S. • Austin, Texas, U.S. • Washington, D.C., U.S. • Boston, Massachusetts, U.S. Position Summary At HackerOne, identity is at the heart of how we protect the data we are trusted with most, our customers' vulnerabilities. We are building our Identity and Access Management capability with an AI-first approach, focused on engineering and not administration alone. As a Senior Security Engineer, you will design and deliver the access models and the automation behind them, so that people and systems can access only the right data, at the right time, in the right way. This role operates across the full identity lifecycle, from onboarding and creation through change and removal, for people, service accounts, and AI agents alike. You will help scale what a small team can accomplish by embedding automation, intelligence, and AI into how access is granted, reviewed, and removed, working toward least privilege for humans and least agency for AI. At HackerOne, we embrace a Flexible Work approach that gives us the freedom to do our best work while also fostering the connections and community that make us stronger. Reflecting this philosophy, this is a remote role targeted for candidates within ~50 miles of Austin TX, Seattle WA, Washington DC, San Francisco CA, or Boston MA, or within commuting distance of our London or Netherlands locations. We believe this balance of proximity and flexibility gives Hackeronies the chance to occasionally come together, fostering collaboration, connection, and in-person moments that enrich our culture, while still preserving the benefits of remote work. What You Will Do Success in the Senior Security Engineer, Identity and Access Management role will be accomplished by delivering on the responsibilities below in alignment with the Values and Principles that define how we work at HackerOne: • Own the identity lifecycle end to end, from onboarding and creation through change to removal, for people, service accounts, and AI agents alike, building the automation that grants entitlements on evidence of legitimate need and removes them seamlessly and automatically • Design and build the access models on top of data classification, so that what an identity can reach follows from what the data is rather than from who asked • Make time-bound access the default for critical data, so that the secure path is the easy path • Engineer identity as code, keeping provisioning logic, entitlement policy, and access review rules in version control and under test across systems such as Okta, Lumos, and AWS IAM, applying First Principles Problem Solving rather than configuring by hand in consoles • Build AI and LLM-powered tooling that makes access review and entitlement anomaly detection continuous rather than periodic, embedding AI First practices so unusual patterns surface when they happen rather than at audit, and decide where AI is trusted to carry an access decision and where a person still signs it off • Bring non-human identities
