## Description

You'll be a core part of our two-person IT team, keeping Infinitus teammates productive and secure across their devices, accounts, and tools. Reporting to the IT Lead, you'll handle the day-to-day Help Desk queue, support onboarding and device management, and help build the processes and documentation that let IT scale as the company grows. This is a great fit for someone early in their IT career who wants hands-on experience across support, systems, and security.

This role alternates weekly between two coverage schedules, shared with the IT Lead: an early week (online by 5am to support early-starting teammates, in the SF office by 8am on office days, wrapping up around 2pm) and a standard week (8am-5pm). Office days are Mon/Tues/Thurs, and because IT supports the office network and equipment, expect to be onsite on days when hands-on support is needed.

Your Impact:

 * Keep people productive: Give teammates fast, friendly support across their devices and the tools they use every day, so IT is a help to their work and not a hurdle.
 * Make day one smooth: Be the reason new hires have their accounts, laptop, and access ready when they start, and help offboard people securely when they leave.
 * Keep our devices healthy: Maintain our hardware and software inventory and support the full device lifecycle, using Rippling MDM.
 * Protect the company: Work with the security team to follow security procedures around access, endpoints, and compliance.
 * Build the playbook: Document processes and improve them over time, so IT runs on shared knowledge and not on one person's memory.
 * Grow with the team: Help shape how IT scales as Infinitus grows, with room to take on more over time.

What You'll Do:

 * Provide technical support for end-user hardware across MacOS, ChromeOS, and occasionally Windows and Linux, running diagnostics and debugging to resolve issues quickly.
 * Deliver software support for enterprise applications including Google Workspace, Microsoft 365, and Rippling MDM.
 * Maintain and update software and hardware inventory.
 * Provision and support access to tools including GitHub, Sigma, Figma, Linear, and Confluence.
 * Support onboarding and offboarding for employees and contractors.
 * Monitor, troubleshoot, and maintain the office network and other office equipment, such as monitors, printers, and meeting equipment.
 * Collaborate with the security team to follow security procedures that protect the company, such as access reviews and endpoint compliance.
 * Contribute to strategic IT projects, including planning, implementation, and successful delivery of technical solutions that align with organizational objectives.
 * Document processes, as well as backup and archive data.
 * Keep up to date with advancements and best practices in IT administration.
