Job description

IT SYSTEM ADMINISTRATOR
Freeform builds AI-native manufacturing systems that unify software, hardware, and physics to produce industrial-scale parts at the speed of human ideation. By treating manufacturing as a single integrated system, we unlock a new era of innovation where complex hardware is designed, built, and scaled without limits.
We are looking for an early-career IT As a Junior System Administrator at Freeform. In this role, you will keep the systems that power our factory, engineering teams, and business operations running every day. The work spans helpdesk support, on-premise infrastructure, endpoint management, and networking: bare metal servers, virtualization platforms, storage, and the network fabric that connects them. You will also be the first line of support for the people who depend on those systems. The ideal candidate has a "no job too big or small mentality", learns fast, treats security as a default, and wants to own more of our IT infrastructure as the company grows.
Responsibilities:
  • Provide day-to-day helpdesk and desktop support across Windows and Linux environments
  • Deploy, maintain, and troubleshoot on-premise infrastructure, including bare metal servers, virtualization platforms, and SAN storage
  • Administer and support core identity services, including Active Directory and Azure AD / Entra ID
  • Manage endpoints across the company using Intune, including application packaging, configuration profiles, and Group Policy (GPOs)
  • Support and troubleshoot LAN and WiFi networking, including switching, cabling, wireless access points, and connectivity issues
  • Apply a security-first mindset to all work: patching, hardening, access control, and safe handling of accounts and data
  • Set up, support, and troubleshoot AV and video conferencing systems across conference rooms and shared spaces
  • Onboard and offboard employees, including account provisioning, hardware setup, and access management
  • Maintain inventories of IT assets and licenses, covering hardware, software, and license assignments from purchase to retirement
  • Document systems, network topology, workflows, procedures, and fixes to build out and maintain the IT knowledge base
  • Work with senior IT staff on larger infrastructure projects and take on more scope over time

Basic Qualifications:
  • 3+ years of experience in a system administration role
  • Hands-on exposure to on-premise infrastructure: bare metal servers, virtualization, SAN storage, and networking
  • Solid understanding of networking fundamentals, including LAN and WiFi
  • Experience administering Windows systems and working familiarity with Linux
  • Experience with Active Directory and Azure AD / Entra ID
  • Familiarity with endpoint management (Intune, application packaging, GPOs)
  • Experience setting up and troubleshooting AV and video conferencing systems

Nice to Have:
  • Experience with Kubernetes (k8s)
  • Familiarity with configuration management and infrastructure automation tools such as Ansible or PowerShell DSC
  • Experience with cloud platforms (AWS, Azure, or GCP)
  • Familiarity with monitoring stacks such as Grafana and Prometheus
  • Ability to write basic scripts (Python, Bash, or PowerShell) to automate routine tasks
  • Experience supporting Siemens Teamcenter
  • Experience working in an engineering environment, including supporting engineering applications and development tools (CAD packages, MATLAB, Visual Studio, etc.)
  • Familiarity with CMMC and NIST 800-171 compliance requirements
  • Ability to operate a scissor lift for racking equipment and running cable
  • Strong documentation habits: tracking assets and licenses, writing runbooks and procedures, and keeping records current as systems change
  • Security-first mindset in daily operations and system administration

Additional Requirements:
  • Ability to lift 50+ lbs., climb ladders, and work at height
  • Ability to operate a scissor lift for racking equipment and running cable
  • Willingness to participate in an on-call rotation
  • Willingness to work occasional weekends to support maintenance windows and critical operations

Location:
  • Based in Hawthorne, our vertically integrated facility brings technology development, R&D, and production together under one roof. We operate at the center of LA's deep tech ecosystem, surrounded by some of the most ambitious hardware innovation happening anywhere in the country.
  • Our fast-paced, cross-functional environment is built on close collaboration, and as such, this role requires full-time onsite presence (five days a week), with very limited exceptions.

Why Freeform?
  • We have an inclusive and diverse culture that values collaboration, learning, and making deliberate data-driven decisions
  • We offer a unique opportunity to be an early and integral member of a rapidly growing company that is scaling a world-changing technology
  • Benefits
    • Significant stock option packages
    • 100% employer-paid Medical, Dental, and Vision insurance (premium PPO and HMO options)
    • Life insurance
    • Traditional and Roth 401(k)
    • Paid vacation, sick leave, and company holidays
    • Generous Paid Parental Leave and extended transition back to work for the birthing parent
    • Free daily catered lunch and dinner, and fully stocked kitchenette
    • Casual dress, flexible work hours, and regular catered team building events
  • Compensation
    • As an early-stage startup, the salary range is intentionally wide as we determine the most appropriate package for each individual taking into consideration years of experience, educational background, and unique skills and abilities as demonstrated throughout the interview process. Our intent is to offer a salary that is commensurate for the company's current stage of development and allows the employee to grow and develop within a role.
    • In addition to the significant stock option package, the estimated salary range for this role is $80,000 - $100,000 per year. The upper end of the range is reserved for individuals who demonstrate exceptional experience, deep domain mastery, and a proven history of high performance and impact.
  • Freeform is an Equal Opportunity Employer that values diversity; employment with Freeform is governed on the basis of merit, competence and qualifications and will not be influenced in any manner by race, color, religion, gender, national origin/ethnicity, veteran status, disability status, age, sexual orientation, gender identity, marital status, mental or physical disability or any other legally protected status.
