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.

Corporate Security Architecture & Engineering

• Design, build, and operate security controls for Atlan’s corporate environment: macOS fleet, SaaS applications, corporate identities, email, endpoints, and network edge.
• Evaluate, select, deploy, and operate the corporate security stack: EDR/XDR, MDM, ZTNA, CASB/SSPM, email security, DLP, and browser security.
• 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, leveraging LLMs to accelerate security workflows.
• Lead security reviews of new SaaS adoptions, corporate infrastructure changes, and IT projects.

Roadmap & Cross-Team Collaboration

• Own the Corporate Security roadmap, aligning investments to Atlan’s risk register and compliance calendar.
• Provide technical direction and security guidance to IT Operations on endpoint provisioning, network design, and access controls.
• Partner with Detection & Response on telemetry coverage, detection engineering, and incident handling for corporate-sourced events.
• Support compliance programs (ISO 27001, ISO 42001, SOC 2, HIPAA, GDPR) by ensuring corporate security controls satisfy audit evidence requirements.

What makes you a great match for us?

Must Have

• 5+ years of hands-on Security Engineering experience in corporate/enterprise security (endpoint, network, SaaS, or identity).

• Deep experience with macOS fleet security (primary endpoint platform).
• Hands-on experience deploying and operating EDR/XDR, MDM, ZTNA, and identity security solutions at scale.
• Understanding of modern SaaS security challenges: shadow IT, OAuth token sprawl, and data exfiltration paths.
• Excellent communication skills to translate complex security topics into clear recommendations.

Strong Bonus

• Experience securing corporate environments at high-growth SaaS, AI, or developer-tools companies.
• Advanced macOS security (system extensions, Endpoint Security framework, MDM profile engineering).
• Network security architecture for distributed/remote-first environments.
• Proficiency in Python, Go, or similar languages for security automation.
• Experience leveraging LLMs/AI to augment security operations.
• Exposure to ISO 42001 (AI Management Systems) controls.
