About the Job

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.

What You'll Get To Do

Endpoint Fleet Management: 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.

Network Operations: 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.

Endpoint Security: 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.

Compliance Partnership: 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.

Senior Technical Escalation: 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.

What You Have

Senior IT Operations Background: 5+ years of IT engineering experience, including time as a senior individual contributor on a small IT team in a fast-paced startup environment.

Linux & macOS Expertise: Deep Linux internals knowledge — systemd, kernel and networking subsystems, package management, sso integration, and host-level diagnostics. Equivalent fluency administering macOS at scale.

MDM Expertise: Production experience administering and scaling a modern MDM platform, ideally JumpCloud — policy authoring, configuration profiles, and rollout strategies across a heterogeneous fleet.

Networking Depth: Hands-on experience with professional-grade networking equipment such as Sophos, Ubiquiti, or Fortinet — switches, firewalls, Wi-Fi, and VPN — including packet-level troubleshooting.

Cloud & SaaS Administration: Hands-on administration of Google Workspace, GitHub, AWS, and Jira Cloud, with strong fundamentals in SSO/SAML/OIDC, SCIM provisioning, and IAM hygiene.

Endpoint Security: Working experience with CrowdStrike Falcon or a comparable EDR/XDR platform — sensor deployment, policy configuration, detection tuning, and incident triage.

Compliance Experience: Practical experience supporting SOC 2 and/or ISO 27001 — operationalizing controls, collecting evidence on a recurring cadence, and partnering with auditors.
