Provides senior-level IT support and escalations across Windows, macOS, and Linux. Owns endpoint, device, identity, Microsoft 365, security, asset, and service management; automates workflows with PowerShell; performs root cause analysis; maintains documentation; supports networking and onboarding/offboarding; mentors junior staff; participates in on-call coverage; and travels to company sites for operational support.
Hermeus is a venture-backed defense aviation company reclaiming the lost art of rapid iterative prototyping to build the fastest aircraft in the world today. By prioritizing relentless hardware iteration, we deliver high-speed systems at the pace of the modern battlefield. We work with the Department of War to provide the high-speed capabilities our nation and its allies need to maintain a durable, asymmetric advantage.
About The Role:
As a Senior IT Support Specialist, you will be a senior individual contributor and the hands-on technical anchor for daily IT operations. You will resolve the issues no one else can, mentor junior staff, and own the technical layer beneath the service desk: endpoint management, identity, and endpoint security. We are looking for someone who does not just close tickets but eliminates the work behind them, automating manual processes with PowerShell, replacing one-off fixes with repeatable procedures, and maturing how IT operates as we scale. You will partner closely with our Cyber, Networking, and People teams on work that crosses team boundaries.
This role reports to the IT Service Desk Manager and is based on site at our Los Angeles office. Two shifts are available, 7:00am to 4:00pm or 9:00am to 6:00pm, with flexibility based on team coverage. Candidates are expected to travel to other Hermeus sites to support projects and operations.

- Support endpoint security controls including Microsoft Defender, BitLocker, FileVault, and encryption enforcement.
- Partner with Cyber on endpoint hardening, vulnerability remediation, and incident response, and ensure compliance with information security, export control, and data privacy requirements.

- Act as a trusted IT partner to engineering, manufacturing, and business teams.
- Own the knowledge base and maintain accurate SOPs for supported systems and recurring procedures.
- Identify manual, repetitive, or undocumented processes and mature them into automated, repeatable workflows as the company scales.
