We’re looking for an IT Operations Manager to own and scale our IT function. This is a hands-on role today: you’ll manage devices, support employees, maintain on-prem equipment, and build out the internal cloud infrastructure that powers our business. As the company grows, you’ll take on a more strategic role — setting the IT roadmap, managing vendors, and building an IT team. You’ll collaborate closely with our Cloud/SecOps team: aligning on security, integrations, and shared infrastructure, while owning the operations, employee-facing cloud systems, and support side of IT. Responsibilities Lead IT operations: endpoint management, device lifecycle, and vendor management. Be hands-on with support: onboarding, troubleshooting, tickets, and escalations. Manage on-prem hardware, office networking, and SaaS tooling. Design and implement internal cloud infrastructure for IT operations (e.g., SSO/IdP, MDM, IAM, automation, SaaS integrations). Support implementation of IT processes such as MFA, SSO, endpoint management, logging, and patch management. Improve reliability and efficiency of internal systems, with a focus on employee productivity. Collaborate with the Cloud/SecOps team on infrastructure integrations, identity management, and compliance readiness. Evaluate, select, and manage IT vendors (hardware, SaaS, MDM, networking). Document IT workflows and continuously improve processes for scale. Support compliance readiness and security audits by aligning IT operations with organizational policies and compliance frameworks. Anticipate future needs: prepare for IT team growth, design scalable processes, and eventually mentor/manage IT staff. Requirements 6+ years in IT or infrastructure roles, with at least 2 years of ownership or leadership experience. Strong hands-on experience with device management, networking, and internal cloud systems (AWS/GCP/Azure for IAM, automation, SaaS integrations). Proven success implementing IT processes and internal tooling in a growing organization. Excellent communication skills — able to set direction, influence stakeholders, and work cross-functionally. Comfortable being hands-on today while preparing to take on a more strategic leadership role as we scale. Familiarity with regulated, compliance-driven environments (e.g., CMMC, SOC 2, ISO 27001, NIST) and experience supporting compliance initiatives is a plus. Benefits Health Care Plan (Medical, Dental & Vision). 401k with 5% matching. Paid Time Off (Uncapped Vacation, plus Sick & Public Holidays). Flexible hybrid work arrangement.
