[Hiring] Senior Security Engineer @Atlan

Role Description

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.

• 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.
• 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 using 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.

Qualifications

• 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.
• Strong engineer who still writes code regularly.
• Deep experience with macOS fleet security.
• 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.

Requirements

• 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.

Benefits

• Competitive Compensation: strong base salary, performance-based variable pay, and impact-driven equity.
• AI Native Culture: AI is woven into how we build, think, and work every day.
• Health & Wellness: health, dental, vision, and mental health benefits from Day 1.
• Flexible Time Off & Leave Policies: modern leave policies to support work-life balance.
• Accelerated Growth & Learning: develop through cutting-edge tech and complex implementations.
• Global, Remote-First, High-Trust: work from anywhere in a diverse team across 15+ countries.
