Senior Mechanical Engineer (Stress Analysis)

Interested in helping us transform thermal and electric energy?

Become a part of the leading Generation-IV nuclear plant development team.

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, each of whom will:

• Offer US market experience and perspectives bringing innovative approaches to problem solving and business plan execution.
• Has demonstrated exceptional results in past engineering projects.
• Offers exceptional leadership and team building capabilities.
• Has a deep understanding of the requirements for advanced reactor development.
• Assist in the creation of the organization architecture and structures based in Charlotte and necessary for the successful design development of the Company IMSR plant.
• Capable of flexibility and adaptability at a time of organizational change.
• Has skillset and experience that relate to the following role:
