IT & Security Manager Austin, TX , San Jose, CA

San Francisco, Bay Area OR Pittsburgh, PA OR Tucson, AZ

Efficient Computer is rethinking computing from the ground up to solve one of AI's biggest challenges: energy. Our Fabric architecture delivers a 10–100x improvement in energy efficiency for general-purpose computation, including AI, while supporting familiar programming languages and software frameworks—unlocking new possibilities for autonomous machines, intelligent infrastructure, wearables, and space systems. With our first processor, Electron E1, now shipping in volume and more than $97 million in Series B financing recently announced, we're accelerating customer deployments and scaling our architecture to data center performance.

Join us to build the hardware and software that bring intelligence wherever it's needed and help shape the next generation of computing.

Efficient Computer is looking for an IT Manager to own information technology end to end across a fast-growing, multi-site startup. You will be our sole IT team member, equally comfortable swapping a dock in the office and briefing leadership on our security posture and compliance roadmap.

This is not a junior helpdesk position. Day to day you will keep the employee experience running smoothly, but the reason this role exists is bigger than ticket resolution. You will build and run the systems, policies, and controls that let a company working in and around the defense ecosystem operate securely and pass scrutiny. You will be the first line of defense for the company, and the person thinking two quarters ahead about where our IT and security needs are going.

Employee experience and IT operations

• Own day-to-day IT support across all offices: hardware, software, accounts, and access. No ask is too small, and you'll build systems so the small asks stay small.
• Run employee onboarding and offboarding end to end: provisioning, deprovisioning, access reviews, and equipment lifecycle.
• Manage laptop fleets and mobile device management (MDM), including configuration baselines, patching, and endpoint security.
• Administer identity and access: SSO via Rippling, Google Workspace, MFA, SCIM provisioning, and role-based access across our SaaS stack.
• Own office IT infrastructure across four sites: networking, Wi-Fi (including RADIUS-authenticated networks), conference rooms and AV, printers, and physical access systems where applicable.
• Manage IT vendors, licensing, and renewals, and keep spend sensible.

AI tooling and governance

• Help shape and administer the company's AI usage policies: which tools are approved, how they're provisioned, and how sensitive data stays out of them.
• Own AI tool spend and seat management, monitoring usage and controlling costs so budget goes where it delivers value.
• Ensure employees are genuinely supported and productive with AI tools while steering usage toward the right tool for the job (not every task needs a frontier model).

Security and compliance

• Serve as the company's first line of defense: monitor for and respond to security events, phishing attempts, and incidents, and run the playbooks you'll write.
• Own compliance with CMMC and other defense-related IT standards (e.g., NIST SP 800-171), including gap assessments, remediation plans, evidence collection, and audit readiness.
• Establish and maintain policies and controls for handling sensitive and controlled information, and train employees on them.
• Get in front of strategic security: build the roadmap for where our security program needs to be as the company scales, and drive it, rather than waiting for requirements to arrive.
• Partner with leadership, legal, and engineering on customer and government security requirements, questionnaires, and audits.

Strategy and scale
