Senior IT & Security Operations Engineer

FieldAI • Irvine, CA

3h • Onsite

About The Position

Field AI is looking for a senior hands-on IT infrastructure engineer to own the systems that keep a robotics engineering organization secure and productive: macOS/Linux endpoints, identity, SaaS access, office/lab networking, and endpoint security. This role is ideal for someone who has operated in fast-moving startup environments, enjoys building durable systems from imperfect starting points, and can move between strategic design and hands-on troubleshooting.

Requirements

• 5+ years of IT engineering experience, including time as a senior individual contributor on a small IT team in a fast-paced startup environment.
• Deep Linux internals knowledge — systemd, kernel and networking subsystems, package management, sso integration, and host-level diagnostics.
• Equivalent fluency administering macOS at scale.
• Production experience administering and scaling a modern MDM platform, ideally JumpCloud — policy authoring, configuration profiles, and rollout strategies across a heterogeneous fleet.
• Hands-on experience with professional-grade networking equipment such as Sophos, Ubiquiti, or Fortinet — switches, firewalls, Wi-Fi, and VPN — including packet-level troubleshooting.
• Hands-on administration of Google Workspace, GitHub, AWS, and Jira Cloud, with strong fundamentals in SSO/SAML/OIDC, SCIM provisioning, and IAM hygiene.
• Working experience with CrowdStrike Falcon or a comparable EDR/XDR platform — sensor deployment, policy configuration, detection tuning, and incident triage.
• Practical experience supporting SOC 2 and/or ISO 27001 — operationalizing controls, collecting evidence on a recurring cadence, and partnering with auditors.

Nice To Haves

• Scripting proficiency in Python, Bash, or similar for IT and identity automation
• Experience standing up or maturing a JumpCloud deployment from the ground up
• Background supporting robotics, hardware, or lab environments
• Prior on-call or incident response experience in a security-conscious environment
• Vendor management and procurement experience for IT and security tooling

Responsibilities

• Own the full lifecycle of our macOS and Linux endpoint fleet through JumpCloud MDM, enrollment, configuration, application deployment, patch management, and compliance enforcement.
• Define and maintain the golden configurations every new device is built from.
• Operate the office and lab network end to end, switches, firewalls, Wi-Fi, VLANs, and VPN.
• Design and configure network infrastructure, perform maintenance and upgrades, and provide deep-dive troubleshooting from layer 1 through layer 7.
• Operate CrowdStrike Falcon as our primary EDR — deploy sensors, define prevention and detection policies, tune detection logic to reduce false positives, and lead first response on endpoint security incidents.
• Partner with Security and Legal on SOC 2 and ISO 27001 — translate framework requirements into operational controls, automate evidence collection, and own the IT-side response to audits and quarterly access reviews.
• Serve as the senior technical resource on the IT team — resolve complex incidents, document resolutions as runbooks, and automate the underlying root cause wherever possible.

Benefits

• Generous salary range
• Opportunity to work with a world-class team
• Work on solving one of the world's most complex challenges: deploying robots in unstructured, previously unknown environments
• Be part of the next robotics revolution
• Fun, close-knit team
