An overview of this role As a Senior Corporate Security Engineer, you'll help secure the systems GitLab team members rely on every day across a fully remote environment. This role sits within Corporate Security Engineering and focuses on building secure-by-default controls for endpoints and the SaaS platforms that support them, with a strong emphasis on macOS. You'll own meaningful technical decisions around endpoint hardening, automation, and detection, and you'll help turn security requirements into scalable engineering systems that are measurable, auditable, and designed to reduce friction for end users.

This is a strong fit if you're motivated by solving security problems with code. You will work across endpoint management, identity, and security operations to improve how GitLab manages macOS, iOS, Windows, and Linux devices through Infrastructure-as-Code, Terraform, and GitOps workflows. In your first year, you'll be expected to strengthen endpoint security architecture, expand automation, and improve the reliability and auditability of how controls are deployed and maintained. What you’ll do - Lead the security architecture of GitLab's endpoint fleet and related infrastructure, with a primary focus on macOS. - Design and support automation for secure endpoint deployment, configuration, and lifecycle management using code-based workflows. - Manage endpoint and SaaS security configuration through Terraform, version control, merge requests, continuous integration pipelines, and automated rollouts. - Define and enforce security baselines across macOS, iOS, Windows, and Linux endpoints. - Develop patching and software distribution approaches that align with security, compliance, and operational requirements. - Partner with Information Technology, Security Operations, and Detection and Response teams to improve endpoint telemetry, detections, and response models. - Drive process improvements that reduce manual work and lower risk by favoring automation, policy-driven controls, and auditable change management. - Mentor engineers across Corporate Security and Information Technology, and serve as a senior escalation point for complex endpoint security issues. What you’ll bring - Experience designing and delivering endpoint, systems, or corporate security solutions in environments that require scalable, durable controls. - Deep knowledge of endpoint management platforms such as Jamf Pro or FleetDM, especially for architecting and securing macOS environments.
