About Thea Energy:  
Thea Energy is leveraging recent breakthroughs in stellarator physics and engineering to create a faster and simpler approach to commercializing fusion energy. The company is reinventing the stellarator using computer-controlled arrays of planar coils thereby replacing the intricate, complex modular magnets required in all other stellarator architectures. Thea Energy is on a mission to create a limitless source of zero emission energy for a sustainable future.  
 
Position Overview:
We are seeking a highly motivated IT Systems Support Engineer to be based at our New Jersey headquarters. As our second IT hire, you will be a key bridge between hands-on user support and deep-tier systems engineering, reporting directly to and collaborating closely with Thea Energy’s Director - IT across all things infrastructure, security, and support. This is a high-impact, high-ownership role for someone who enjoys building robust systems from the ground up. You'll ensure our scientists, engineers, and executives have a frictionless path to the tools they need - with a leading role in shaping how the Company’s digital foundation is built.
This role spans both strategic and operational IT, from supporting our scientists and engineers day-to-day to building the systems and automation that scale with the Company.
  • Own day-to-day IT operations as a primary point of contact for user support, while continuously building and improving the underlying infrastructure.
  • Design and deploy automated workflows to ensure smooth employee onboarding, offboarding, and lifecycle transitions.
  • Manage physical and virtual server environments, ensuring high availability, consistent patching, and strong security practices.
  • Optimize cloud environments, manage identity and access, and maintain a strong security posture across the organization.
  • Maintain office and lab network infrastructure - including VPNs, firewalls, switches, and Wi-Fi - ensuring reliable, low-latency connectivity.
  • Build and maintain a thorough knowledge base: clear documentation and infrastructure diagrams that the whole team can rely on.
  • Manage hardware and software lifecycles, including inventory, procurement, and vendor relationships.
  • Administer and maintain our MDM environment: managing device enrollment, compliance policies, and configuration profiles across Windows and macOS.
  • Implement and uphold security best practices to protect mission-critical intellectual property and research data.
  • Proactively identify and reduce technical debt through automation and process improvement.
  • 5+ years of experience in systems engineering and desktop support across Windows and macOS.
  • Proficiency in PowerShell, Python, or similar scripting/automation tools.
  • Experience managing network infrastructure, including firewalls, switches, and access points.
  • Hands-on experience with at least one major cloud platform (Azure, GCP, AWS, or Google Workspace/O365).
  • Experience with modern IT ticketing systems (e.g., ServiceNow, Zendesk, Freshdesk) and structured support workflows.
  • Strong documentation skills - able to translate complex systems into clear diagrams and written guides.
  • Excellent communication skills - comfortable explaining technical issues to both engineers and non-technical stakeholders.
  • A collaborative, low-ego approach: equally comfortable supporting a user with a hardware issue and leading a server migration.
  • Ability to thrive in a fast-moving, high-growth environment where priorities can shift quickly.
  • Experience across multiple cloud platforms (Azure, GCP, AWS, Google Workspace/O365).
  • Background working in a startup, research, or scientific/engineering environment.
  • Familiarity with compliance frameworks or security standards (SOC 2, NIST, etc.).
  • Experience with email security platforms (e.g. Barracuda, Proofpoint, Mimecast).
  • Familiarity with Security Awareness Training tools (e.g. NINJIO, KnowBe4, Proofpoint).
  • Salary range $85,000-$145,000
  • Comprehensive health benefits (e.g. medical/dental/vision)
  • Employee equity stock options
  • 20 days PTO
