Senior Security Engineer - Corporate Security

Cogent Security is on a mission to stop breaches and prevent cybercrime by innovating at the frontier of generative AI systems. They are seeking a Senior Security Engineer to own the security of internal systems and enterprise tooling, hardening systems, and building controls to ensure safety as the company grows.

Responsibilities:

• Harden and manage endpoints across the fleet (macOS, and others as needed): baseline hardening, device posture, EDR coverage and tuning
• Own corporate identity and access: SSO/MFA, least-privilege access, and identity hygiene across our SaaS stack
• Secure and standardize our enterprise systems and SaaS environment; drive Zero Trust / device-trust patterns
• Build automation and tooling to enforce security configuration and scale controls without slowing the team down
• Handle enterprise security operations - detection, monitoring, and response for corporate systems
• Serve as the internal security SME on corporate systems and workflow decisions, and as an early user of what we build

Requirements:

• 5+ years of experience building and managing corporate security / IT security programs
• Strong hands-on engineer who produces vs. just manages process
• Deep experience hardening endpoints and enterprise systems, with solid OS internals knowledge (macOS, Windows, Linux)
• Experience across CorpSec domains: endpoint security, corporate identity, SaaS security, device trust, Zero Trust
• Automation ability to build and maintain tooling (e.g. Python, or similar) - you look for smart and secure ways to automate your work to scale yourself
• Able to flex up and down: strategic when it matters, in the weeds when it counts
• Comfortable being an early security hire at a startup - high ownership, ambiguity, and direct impact
• Experience standing up a CorpSec function or building enterprise security from an early stage, 0-1
• Familiarity with compliance frameworks (e.g. SOC 2) and supporting audits
• DLP, secrets management, or corporate network security experience
