About The Role
We're hiring a Senior Security Engineer, Corporate Security to own the security of our internal systems, endpoints, and enterprise tooling. You'll harden the systems our team relies on every day: laptops, identity, SaaS, the corporate environment - and build the controls and automation that keep us safe as we grow. Ultimately you’ll be responsible for securing our workflows and the systems that run the company.
What You’ll Do
- 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
What We're Looking For:
- 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
Bonus Points
- 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
- Using AI coding tools and agentic workflows daily to move faster and automate more of your own work
