About the Role

If you’re the kind of security engineer who can spot an active threat , contain it calmly , and then harden the environment so it doesn’t happen again , this role is built for you.

We’re hiring a hands-on Senior Security Analyst / Security Engineer to strengthen a Microsoft-centric security posture across detection, response, tooling, and infrastructure hardening .

This is not a one-lane SOC role and not a governance-only position. If you enjoy both incident response and engineering security controls , this one’s for you.

You’ll work across detection, response, vulnerability management, security tooling, M365 security, and infrastructure hardening. Ideal for someone with 4–5 years’ experience who wants real technical ownership — not just alert monitoring.
