Job Opening: Mechanical Engineering Manager

Company Brief

Terrestrial Energy is a developer of Generation IV advanced nuclear power plants that use its proprietary Integral Molten Salt Reactor (IMSR®) technology. IMSR® technology represents true innovation in cost reduction, versatility and functionality of nuclear power plants. IMSR® power plants will provide zero-carbon, reliable, dispatchable, cost-competitive electric power and high-grade industrial heat for use in many industrial applications, such as chemical synthesis and desalination, and in so doing extend the application of nuclear energy far beyond electric power markets. We have the potential to make important contributions to industrial competitiveness, energy security, and economic growth. Our deployment will support rapid global decarbonization of the primary energy system by displacing fossil fuel combustion across a broad spectrum. Using an innovative design, and proven and demonstrated molten salt reactor technology, we are engaged with regulators and industrial partners to complete IMSR® engineering and to commission first IMSR® power plants in the late 2020s. To execute this plan, we are now looking to add talented people to the team, each of whom will:

  • improve our team by adding diverse perspectives and innovative ways of problem solving
  • have demonstrated exceptional results in engineering projects
  • be a team player with the ability to collaborate closely and interact with other groups
  • be flexible and adaptable to change
  • have skillset and experience that relate to the following role:
