Sr. Corporate Security Engineer

Senior corporate security engineer at Material Security, which protects customers' Google Workspace, responsible for making the company's own Mac-based, Workspace-centred environment rigorous and measured. The engineer owns corporate detection and response, building detections for account takeover, token theft, malicious OAuth grants and insider exfiltration and leading incident response, and designs an LLM agent that triages privileged access grants and alerts with measured precision and safeguards. Shared work covers MDM and EDR on the fleet, phishing-resistant identity, SaaS and OAuth review, Workspace governance and the corp-to-production boundary, feeding lessons back into the product.

Material wants six or more years in corporate security or detection and response with SIEM and incident ownership, Python, Go or TypeScript, deep OAuth and SAML knowledge and real LLM workflow experience. The role is remote.
