Terrestrial Energy Inc.
Interested in helping us transform thermal and electric energy?
Become a part of the leading Generation-IV nuclear plant development team.
This position is remote until the office opens in or around Bryan, TX on or before February 2026, after which time it will be a 100% on site role.
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 U.S. markets created by the policies of the U.S. Federal and state governments, and by the actions of the U.S. industrial private sector, including its world‑leading IT sector developing AI commercial products. The company recognizes that its path to business success and likely sole path to success is to wholly align with the U.S. market as a U.S. 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 U.S. in 2023, which it completed in April 2024, with 100% shareholder support. This transaction was the first step in its U.S. domiciliation strategy. The company is currently completing a transaction to secure a U.S. exchange (NASDAQ) public stock listing, which is expected to secure the capital resources necessary to complete its U.S. domiciliation as well as execute on its business plan focused on the U.S. 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 U.S. team, each of whom:
Will offer U.S. market experience and perspectives bringing innovative approaches to problem solving and business plan execution.
Has demonstrated exceptional results in past engineering projects.
Will offer exceptional leadership and team building capabilities.
Has a deep understanding of the requirements for advanced reactor development.
Will 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.
Is capable of flexibility and adaptability at a time of organizational change.
Has skillset and experience that relate to the following role:
The experienced Mechanical Engineering Manager, reporting to the Engineering Director, will primarily be responsible for leading our mechanical engineering function within a dynamic matrix organization. This senior leadership role will provide functional management for the Mechanical Engineering, Stress Analysis, CAD Design, and Thermal Hydraulic groups, ensuring technical excellence while supporting project delivery across multiple programs. The successful candidate will be responsible for building and maintaining a world‑class engineering team capable of delivering innovative solutions for the commercialization of the Integral Molten Salt Reactor.
Key Responsibilities
You will serve as the functional leader responsible for the supervision, professional development, and technical qualification of mechanical engineering staff across multiple disciplines.
You will establish and maintain engineering standards, processes, and procedures that ensure compliance with nuclear industry codes and standards including ASME, CSA, and relevant regulatory requirements.
Your role will involve workforce planning, recruitment, and retention strategies to build organizational capability aligned with business objectives.
You will provide technical oversight and guidance to ensure engineering deliverables meet quality standards and project requirements while fostering a culture of innovation and continuous improvement.
In the matrix organization structure, you will collaborate closely with project managers and other functional leaders to allocate resources effectively, balance workload across the Engineering Department, and resolve competing priorities.
You will be accountable for the performance management of your team, including conducting regular reviews, identifying skill gaps, and creating individual development plans that support both employee growth and organizational needs. The position requires establishing and maintaining technical competency frameworks for each engineering discipline under your supervision, ensuring that staff members possess the appropriate qualifications and certifications required for nuclear engineering work.
You will serve as a technical lead within the organization, participating in design reviews, providing input on major technical decisions, and representing the mechanical engineering function in interactions with regulators, customers, and industry partners.
