Now, we're striking out on our own to tackle an even bigger challenge: stopping the new wave of adversarial AI attacks already hitting organizations today. We're going after a $5B+ market, ripe for disruption. Traditional detection methods are too slow to keep up. Adversaries are using AI to craft customized, high-evasion attacks — and old-school rules-based systems don't stand a chance.

The Role We're looking for a Security Administrator to keep AegisAI’s own environment running securely. You'll run vulnerability management, tune and monitor our SIEM, and harden every endpoint we ship, working directly with our security engineering team. Because our fleet and our identity stack are the attack surface, you'll administer them too: MDM, patching, and day-to-day access needs are part of the job, not a detour from it. You'll be the person your teammates rely on when something breaks, and the person our security program relies on to keep the fleet patched, monitored, and clean. You'll learn how a security company secures itself. This is a growth role, and scope scales with what you bring. If you're coming from help desk or IT support and want a real path into security operations, this is that path. If you already have a few years of IT and security work behind you, you'll take ownership of these areas faster and help shape how we run them.

What You'll Do Vulnerability management: Run our remediation workflows - track findings, coordinate fixes with engineering, and keep us inside our SLAs. SIEM monitoring & tuning: Watch and triage alerts in our SIEM, and help tune detections to cut noise and catch what matters. Identity & access management: Harden our identity stack and run access reviews and provisioning across our SaaS estate. MDM administration: Manage our device fleet: enrollment, configuration profiles, and security policies. Endpoint patching & updates: Keep operating systems and applications current across the fleet, and track patch compliance. Software review & packaging: Review, package, and deploy software to endpoints. IT support: Answer help requests across the company: accounts, devices, access, and the occasional mystery. Automate: Automate the boring work so you can focus on what matters most

Who You Are 1–4 years of hands-on experience in IT support, help desk, or systems administration. Solid cloud and identity fundamentals: you understand SSO, MFA, and how cloud native companies manage access. Demonstrated interest in security: certifications (e.g., Security+), coursework, homelab projects, CTFs, or security-adjacent work experience all count. Comfortable picking up new tools and figuring things out independently, and honest about what you don't know yet. Strong written communication: clear tickets, clean documentation, useful runbooks.

Bonus points: Experience with MDM. Experience with vulnerability management and patch management tooling. Experience with SIEM tuning, threat hunting, and log analysis tools. Identity provider and SaaS administration experience. Our Culture Flat, flexible, and fast. You'll own your decisions. You'll have clear KPIs for success — but how you get there is up to you. If you're hungry to build a career in security, and want to work with a team that moves at the speed of the real world, join us.
