Civil Engineering Intern

This is a Full-time 16-month role commencing May 2026

Terrestrial Energy is developing for near-term commercial operation, a zero-emissions cogeneration plant for a global industry using its proprietary Integral Molten Salt Reactor (IMSR) fission technology in an innovative, small and modular plant design.

Over the last 5 years, the Company has recognized the exceptional and unmatched opportunities in US markets created by the policies of the US Federal and States' governments, and by the actions of the US industrial private sector, including its world leading IT sector developing AI commercial product. The Company recognizes that its path to business success and likely sole path to success, is to wholly align with the US market as a US company, and effect all the organizational changes necessary to achieve this alignment. 

In pursuit of this objective, Terrestrial Energy initiated a transaction to legally redomicile the business to the US in 2023, which it completed in April 2024, with 100% shareholder support.  This transaction was the first step in its US domiciliation strategy. The Company is currently completing a transaction to secure a US exchange (NASDAQ) public stock listing, which is expected to secure the capital resources necessary to complete its US domiciliation as well as execute on its business plan focused on the US market.  

The Company is focused on building a team of business professionals and leaders in the engineering, R&D, product management and business development areas out of our Charlotte, North Carolina location.  These key resources will help build the organization structure and processes in Charlotte, NC, which will be the cornerstone to add talented people to the US team.

• Familiarity with fundamental seismic design concepts such as response spectra, PGA, design basis earthquake criteria, and code-referenced seismic parameters.
• Basic exposure to soil–structure interaction concepts, including foundation flexibility and soil modulus concepts, through coursework or academic projects
• Proficiency with Microsoft Office (Excel, Word, PowerPoint, Visio)
• Basic familiarity with CAD tools (AutoCAD, Revit, or similar).
• Strong problem identification and problem resolution skills
• Flexibility to adjust to shifting priorities and deadlines
• Skilled at developing and maintaining strong relationships across all levels of the organization and with external customers and vendors

Assets:

• Exposure to nuclear design concepts, principles, regulations, codes and standards
• Experience with numerical modelling concepts, including finite element modelling
• Working knowledge of SASSI and ANSYS
• Familiarity with nuclear design standards (eg. CSA N291, CSA N287, ANSI/AISC N690, ACI 349, ASCE/SEI 4, ASCE/SEI 43)
• Familiarity with DOE standards (e.g., DOE-STD-1020)
• Coursework or academic project experience related to:
  • Structural dynamics
  • Geotechnical earthquake engineering
  • Seismic design per ASCE/SEI 7 or ASCE/SEI 43
  • Soil–structure interaction modelling

 Benefits:

• Mentoring/Coaching with Senior Employees/Leaders
