About Us
At Antares, our long-term mission is to make clean energy abundant from Earth to the Asteroid Belt. We’re fueled by the belief that advanced nuclear energy can strengthen our military, solve the climate crisis, elevate global living standards, and expand humanity's presence in outer space. To achieve our mission, we’re building mass-producible, inherently safe, deployable microreactors that can be used terrestrially, underwater, and in space.
The Antares team hails from SpaceX, the White House, the Pentagon, the Department of Energy, MIT, Rigetti Computing, General Atomics, Relativity Space, Ursa Major, and National Laboratories like Idaho, Oak Ridge, Los Alamos, and Savannah River. Antares has raised over $600M in venture capital from top-tier investors and has hundreds of million-dollars on contract with the military services, NASA, and the Department of Energy.
About the Role
As a member of the Antares IT organization, you will keep the technology used by software, engineering, manufacturing, lab, and business teams reliable, secure, and ready for work. You will provide hands‑on support across applicable workspace, Windows, macOS, Linux, mobile devices, identity and access systems, networks, conference rooms, and internal applications in an onsite, regulated environment.
The ideal candidate is an experienced, service‑oriented troubleshooter who can move comfortably between people, devices, and systems. This person communicates clearly under pressure, documents work precisely, and improves recurring workflows rather than repeatedly treating symptoms.
Roles & Responsibilities:
Own Tier 1 through Tier 3 support requests from intake and triage through resolution or clear escalation, maintaining timely and professional communication with users.
Support and troubleshoot Windows, macOS, and Linux endpoints, mobile devices, printers, peripherals, engineering workstations, conference rooms, and approved business applications.
Administer day‑to‑day user, group, license, mailbox, collaboration, and access workflows across Microsoft 365, Entra , or Google Workspace environments.
Provision, configure, enroll, patch, repair, recover, and decommission endpoints using appropriate device‑management, security, and deployment tools.
Troubleshoot identity, MFA, SSO, VPN, wired and wireless connectivity, DNS, DHCP, VLAN, and application‑access issues while following security and change‑control practices.
Manage the lifecycle and inventory of laptops, desktops, mobile devices, accessories, software licenses, and loaner equipment, including secure recovery and disposal.
Support onboarding, offboarding, access changes, hardware moves, and high‑volume deployment events in coordination with People, Security, Facilities, and hiring teams.
Operate relevant ticket queues with clear categorization, prioritization, ownership, SLA awareness, escalation notes, and actionable handoffs to systems, network, security, or application owners.
Create and maintain user‑facing knowledge articles, internal runbooks, configuration records, asset data, and audit‑ready evidence for recurring support processes.
Support collaboration and audiovisual technologies, including Microsoft Teams, Google Meet, Zoom, displays, cameras, audio systems, and room scheduling equipment.
Troubleshoot technology used in manufacturing, lab, and engineering environments, including specialized workstations and network‑connected equipment, without compromising safety or controlled configurations.
Use Power Shell, Bash, APIs, or workflow tools to automate repeatable tasks, reduce ticket volume, and improve consistency and visibility.
Basic Qualifications:
3+ years of hands‑on experience in IT helpdesk, service desk, desktop support, endpoint support,…
