Senior Security Engineer - Corporate Security

Who We Are Atlan is building the context layer for enterprise AI. Enterprises are pouring money into AI and most of it dies in production because the AI does not understand the business context around the data. That is the problem Atlan solves. Gartner has named context the defining issue in enterprise AI, and calls context graphs the essential infrastructure for AI agents, naming Atlan one of three vendors already building it. We are also the only vendor named a Leader across all four major Gartner and Forrester evaluations for data catalogs, data governance and metadata management, the foundation the context layer runs on. Come build the infrastructure that AI runs on. What will you do? 🤔 We are looking for a Senior Security Engineer to own and drive Corporate Security at Atlan. This is a senior individual contributor role with high autonomy and high visibility. You will be the technical authority for everything that protects our people, endpoints, networks, SaaS ecosystem, and corporate data—the full surface area outside of production infrastructure. The scope is broad and the team is lean. You need to have done this before: deployed and operated the core corporate security stack, made architectural calls on tooling, and built engineering-driven solutions over manual processes. We need someone who can hit the ground running and start delivering from week one, not someone who needs technical guidance on what EDR to pick or how to architect zero trust. You will provide technical direction to the IT Operations team on security matters, partner closely with Infrastructure Security, Detection & Response, GRC, and Legal teams, and report into Security leadership. Because Atlan serves regulated enterprises, the security posture of our corporate environment directly impacts customer trust, compliance audits, and deal velocity. Corporate Security Architecture & Engineering Design, build, and operate the security controls for Atlan’s corporate environment: macOS fleet, SaaS applications, corporate identities (Okta/Google Workspace), email, endpoints, and network edge Evaluate, select, deploy, and operate the corporate security stack: EDR/XDR, MDM, ZTNA, CASB/SSPM, email security, DLP, browser security. You will own vendor selection, PoCs, deployment, tuning, and lifecycle management Define and enforce security baselines, hardening standards, and configuration policies across all corporate platforms Drive vulnerability management for corporate assets: patch orchestration, risk-based prioritization, exception tracking, and SLA enforcement Build security automation and internal tooling. We expect you to use LLMs (Claude, custom agents) to accelerate security workflows Lead security reviews of new SaaS adoptions, corporate infrastructure changes, and IT projects Define what it means to operate safely in an environment where AI agents act autonomously across corporate systems Roadmap & Cross-Team Collaboration Own the Corporate Security roadmap.
