HTS R&D Engineer - Superconducting Materials

About Commonwealth Fusion Systems:

Commonwealth Fusion Systems is on a mission to deliver the urgent transition to fusion energy.

Combining decades of research, top talent, and new technologies, we're designing and building commercially viable fusion power plants. And working with policymakers and suppliers to build the energy industry of the future.

We're in the best position to make it happen. Since 2018, we've raised nearly $3 billion in capital, making us the largest and leading private fusion company in the world.

Now we're looking for more thinkers, doers, builders, and makers to join us. People who'll bring new perspectives, solve tough problems, and thrive as part of a team.

If that's you and this role fits, we want to hear from you.

Join the power movement as an HTS R&D Engineer - Superconducting Materials

We are seeking an R&D Superconducting Materials Engineer to join our team. In this role, you'll conduct research and development on cutting-edge high-temperature superconducting (HTS) materials and high-field magnets. This is an excellent opportunity for a highly motivated individual to apply their skills in a hands-on lab environment and contribute to innovative projects.

This role requires compliance with U.S. laws concerning the export of controlled or protected technologies or information (collectively, "Export Control Laws"). Any offer of employment will be contingent on the need for compliance with such Export Control Laws.

What you'll do:

• Perform hands-on characterization of HTS materials using various techniques including transport, magnetization, mechanical and microscopy techniques
• Plan and execute experiments to understand and quantify the effects of strain, AC losses and irradiation of superconducting material on the performance of HTS
• Design and build experimental setups for material characterization and magnet testing
• Analyze and interpret data, and present your findings to both technical and non-technical audiences
• Collaborate with the team and other stakeholders on projects involving high-field magnets

What we're looking for:

• Master's degree or higher in Physics, Mechanical, Electrical, or Nuclear Engineering, Materials Science, or a related field.
• 3+ years experience with superconducting materials, particularly high-temperature superconductors (HTS) like REBCO.
• Practical experience in a lab setting, including experience working with high field electromagnets.
• Familiarity with the use of cryogens, such as liquid nitrogen and liquid helium
• Design of long term projects and project management
• Strong analytical skills for data processing and analysis
• Excellent communication skills, both written and verbal

Bonus points for:

• Experience in measuring response of irradiation on HTS
• Experience working with high field magnets
• Experience in preparing and characterizing REBCO using optical and electron microscopy tools
• Experience working with vacuum and cryo-cooled systems
• Experience communicating with technical teams including vendors and suppliers
• 1+ years experience working in a production environment
• Experience processing and analyzing large quantities of data and applying statistics
• Experience programming instrumentation such as power supplies, nano voltmeters, and temperature controllers using LabView or equivalent software
• Computational modeling with COMSOL or ANSYS
• Proficiency with sample preparation and use of optical and electron microscopes
• Knowledge of fundamental statistical analysis

Must-have Requirements:

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

$90,000 - $145,000 a year
