What we're looking for:

• Bachelor’s degree, preferably in Engineering, Computer Science, Information Technology, or a related STEM field (or equivalent industry experience)
• Proven ability to troubleshoot complex issues, diagnose root causes, and follow logical steps to resolve technical problems
• Strong commitment to end-user support, with patience, empathy, and enthusiasm for helping internal stakeholders solve daily challenges
• Exceptional written and verbal communication skills, with a proven ability to explain technical solutions to non-technical stakeholders
• Core software literacy, including a grasp of conditional logic, basic programming concepts, and data flows across connected systems
• Meticulous attention to detail, ensuring system changes are applied safely and documentation is thorough, clear, and reliable
• Fast learner with high curiosity and strong growth potential, energized by complex problem solving in a dynamic environment
• Deep alignment with our mission to deliver the urgent transition to fusion energy, paired with a genuine passion for solving hard problems
