IT Helpdesk Technician

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 ID, 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 PowerShell, 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, systems administration, or an equivalent technical support role.

• Basic networking concepts and protocols (DNS, DHCP, RDP, SSH, FTP, TCP/IP)

• Professional experience supporting Microsoft and Google environments plus Windows and macOS endpoints.

• Familiarity with remote management and remote support tools (Remote Desktop, TeamViewer, BeyondTrust, NinjaOne, ManageEngine, N-Able, Datto or similar).

• Experience working within a ticketing system (Zendesk, FreshDesk, N-Able, Request Tracker, HelpScout, HaloPSA or HappyFox)

Preferred Skills and Experience:

• Familiarity with IT operations in a high pace environment that requires creative, but well thoughtout approach

• Strong troubleshooting fundamentals across hardware, operating systems, SaaS applications, identity, networks, peripherals, and audiovisual systems.

• Experience supporting aerospace, defense, advanced manufacturing, laboratories, engineering organizations, biotechnology or other high-availability and compliance-driven environments.

• Familiarity with ITAR-controlled environments and frameworks or practices such as NIST SP 800-171, CMMC, least privilege, audit logging, evidence collection, and incident reporting.

• Demonstrated service ownership, calm incident communication, precise documentation, and sound judgment when balancing user urgency with security and operational risk.

• CompTIA A+, Network+, Security+, Microsoft 365 or Endpoint Administrator, Google Workspace Administrator, Jamf, JumpCloud, ITIL, or equivalent certifications are a plus but not required.

• Support of standard office applications such as Microsoft Office, Adobe Acrobat, browsers as well CAD software.

Additional Requirements:

• Ability to participate in an on-call rotation and work occasional evenings, weekends, or extended hours to support critical incidents, milestones, onboarding surges, audits, hardware moves, or facility needs.

• Ability to move and install common IT equipment, including laptops, monitors, small network devices, conference-room equipment, and peripherals; work may include walking through production or lab areas and occasional travel between company or vendor locations.

• Ability to work onsite in Torrance, CA and support urgent engineering, manufacturing, facility, security, or business milestones as needed.

Culture

At Antares, we like to specifically tie each role to our founding document’s set of values–here are the top five cultural values we think you should believe at your core to be successful:

• Think in Systems - Energy and Defense are complex ecosystems with numerous stakeholders with competing priorities, conflicting policies, perverse incentives, and emergent and path-dependent properties. First principles thinking alone is insufficient. Think probabilistically and then take action. “If you want to be certain, then you are apt to be obsolete.” Over-optimizing the components often degrades the system

• Obsess over the End User - The customer and end user are often not the same. We will never build globally competitive commercial products if we lose sight of our end users and their entire interaction with the product life cycle

• Be Unconstrained by Convention - Our only limits are the laws of physics. Many, even experts, will say what we are working on is impossible. They said the same about SpaceX reusing rockets. Generationally impactful companies, by definition, must accomplish the seemingly impossible. If it were easy, it would have already been done. Never shy away from a solution because it has never been tried before, and never choose to do something because that's “how it's always been done”

• Go Where the Work Is - Never miss a chance to meet a customer, user, or stakeholder face to face, even if that means hopping on a plane. If you can’t make it, find a teammate who can channel your intentions and go in your place. Deep work can be done from anywhere, but we believe teams are built in person, and aim to maximize our time together

• Operate in the Grey - Embrace nuance in pursuit of truth. Question every fundamental assumption
