Senior Security Engineer - Corporate Security

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. Align investments to Atlan’s risk register, compliance calendar, and growth trajectory

  • Provide technical direction and security guidance to IT Operations on endpoint provisioning, network design, SaaS lifecycle management, and access controls

  • Partner with Detection & Response on telemetry coverage, detection engineering, and incident handling for corporate-sourced events

  • Collaborate with Infrastructure Security and AppSec teams to ensure security standards are consistent across corporate and production environments

  • Support compliance programs (ISO 27001, ISO 42001, SOC 2, HIPAA, GDPR) by ensuring corporate security controls satisfy audit evidence requirements

  • Communicate security posture, risks, and investment needs to Security leadership and cross-functional stakeholders clearly and persuasively
