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:
Thea Energy is looking for an experienced, highly motivated Electrical Engineer to join its rapidly growing team. The Electrical Engineer will work collaboratively across a cross-functional engineering team to help develop Thea Energy’s core planar coil stellarator fusion technologies. As part of a rapidly growing team, you’ll be part of the organizational build-up of a leading fusion energy company. These roles will have a high degree of autonomy and must be able to move quickly. The Thea Energy team is comprised of self-motivated, creative, and fun individuals with an excitement for solving complex problems.

Key Responsibility Areas:


  • Design, construct, and operate power supplies and control systems for high-temperature superconducting magnets and plasma heating systems (ECRH)
  • Specify, design, develop, fabricate, and commission bespoke electronic systems, encompassing low-signal analog and digital equipment, capable of operating in high-stress industrial environments including high magnetic field, vacuum, and cryogenic temperatures
  • Provide comprehensive specifications and facilitate the procurement of commercial off-the-shelf electronic products
  • Actively engage in discussions to define requirements for the systems to be designed
  • Provide full-cycle project support, from design to operation, including prototyping and testing of samples
  • Collaborate and communicate effectively with engineering, physics/science, project management, and procurement groups
  • Generate and revise work packages, including electrical drawings and technical specifications
  • Manage critical procurement contracts and coordinate with vendors for electrical system design, procurement, and commissioning
  • Select and implement industry standards (IEEE, ANSI, IEC, etc.) for use in prototyping projects and the future fusion power plant ecosystem
  • Maintain a detailed project schedule, oversee the delivery of externally furnished documentation and equipment, and coordinate subcontractors



Ideal Experience & Skillsets:


  • MS, or PhD in Electrical Engineering or related fields
  • 5 years of experience in the design and implementation of electrical and electronic systems in an industrial and/or scientific environment
  • Technical proficiency in multiple areas of electrical engineering, including a subset of the following: power conversion, medium voltage distribution, switchgears, protective relaying, low voltage process-industrial facility design, instrumentation, and control
  • Experience using PCB design software (Altium)
  • Experience using CAD software (AutoCad, Solidworks)
  • Experience in designing front-end analog electronics (differential amplifiers, trans-impedance amplifiers, precise and fast voltage comparators)
  • Experience in the design and implementation of power electronics components: PWM converters (GaN/SiC/MOSFETs/IGBTs.), DCL-capacitors, high-frequency transformers, and inductors
  • Experience using simulation software (PSpice, PLECS, MATLAB, Simulink)
  • Nice to have experience with designing DSP- and MCU-based embedded control systems
  • Experience in the integration of software and hardware in a high voltage, high current environment would be beneficial
  • Experience in pulsed power systems; electrical and mechanical transient analysis and/or design implications in complex power systems
  • Demonstrated ability to manage system installation within a complex project. Ability to interface with contractors, vendors, and designers
  • Excellent written and verbal communication skills, ability to conduct design reviews, and organize/present material to both expert and non-technical audiences
  • Ability to take initiative, work independently, and as part of a team
  • Comfortable working to aggressive deadlines



Company Benefits:


  • Salary range $130,000-$150,000
  • Comprehensive health benefits (e.g. medical/dental/vision)
  • Employee equity stock options
  • 20 days PTO



Requirements:


  • Ability to occasionally lift up to 50 lbs
  • Ability to perform activities such as typing, standing, or sitting for extended periods of time
  • Willingness to occasionally travel or work required nights/weekends/on-call
  • Ability to work in a facility that contains industrial hazards including heat, cold, noise, fumes, strong magnets, high voltage, high current, pressure systems, and cryogenics
