Who We Are

Most companies are racing to deploy AI, but very few have the foundation to make it work reliably. Atlan is building that missing layer: the context layer for enterprise AI. We connect the business context behind data so humans and agents can operate with far more accuracy and confidence.

With backing from world-class investors including GIC, Insight Partners, Meritech, Peak XV, and Salesforce Ventures, we've earned the trust of most AI-forward enterprises like General Motors, Nasdaq, Workday and Elastic.

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. 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

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, identity, or a combination)
Have built or significantly matured a corporate security program before: selected the tooling, defined the architecture, shipped the controls. Not just operated what someone else built
Strong engineer who still writes code regularly. You can prototype a tool, write a detection, build an integration, script an API, or debug a complex configuration issue
Deep experience with macOS fleet security (this is our primary endpoint platform)
Hands-on experience deploying and operating EDR/XDR, MDM, ZTNA/zero trust, and identity security solutions at scale
Understand modern SaaS security challenges: shadow IT, OAuth token sprawl, data exfiltration paths, SaaS-to-SaaS integrations, and CASB/SSPM tooling
Can work independently with high autonomy, manage ambiguity, and make sound risk-based prioritization decisions without waiting for direction
Excellent communication skills: can translate complex security topics into clear recommendations for both engineering teams and business stakeholders
Experience supporting ISO 27001, SOC 2, or equivalent compliance frameworks from the corporate security controls side

Strong Bonus

Experience securing corporate environments at high-growth SaaS, AI, cloud, or developer-tools companies
Advanced macOS security: system extensions, Endpoint Security framework, MDM profile engineering, Declarative Device Management
Network security architecture for distributed/remote-first environments: SD-WAN, ZTNA, DNS security, network segmentation
Browser security and isolation technologies (Island, Talon/Palo Alto, Chrome Enterprise)
Proficiency in Python, Go, or similar languages for building security tooling and automation
Experience leveraging LLMs/AI to augment security operations, build investigative tooling, or automate policy enforcement
Familiarity with IaC (Terraform), CI/CD pipelines, and DevSecOps practices as they apply to corporate infrastructure
Mobile security for iOS/Android in a BYOD environment
Data Loss Prevention (DLP) program design and implementation across endpoints, email, SaaS, and cloud storage
Exposure to ISO 42001 (AI Management Systems) controls
