Mechanical Engineer or Analyst – Model Development
Job Description
Come join us at Terrestrial Energy, a US developer of advanced, Generation IV nuclear reactors. We are growing our workforce to develop and deploy our Integral Molten Salt Reactor (IMSR) small modular nuclear plant to provide cost\-competitive, clean firm heat and power to industry.
The Company has recently completed a merger creating a publicly listed operating company (NASDAQ “IMSR”), to secure the capital resources for our next growth phase. With the current alignment of US Federal and State government, as well as industry interest in Small Modular Reactor (SMR) and advanced reactor technologies such as Terrestrial Energy’s IMSR, there is today a unique and compelling opportunity to participate in the execution of the company’s growth business plan.
The Company is building a team of high\-performing business professionals and leaders in engineering, R\&D, product management and business development areas at our Charlotte, North Carolina headquarters and future project sites. We are looking for talented individuals who can help build the organization, processes, and goal\-orientated corporate culture to lead the company in our expansion. We are seeking people who:
* Have US market experience and perspectives bringing good judgement and innovative approaches to problem solving and business plan execution.
* Have demonstrated exceptional performance in past engineering projects.
* Offer exceptional leadership and team building capabilities.
* Have a deep understanding of the requirements for advanced reactor development.
* Can assist in the creation of the discipline and organized company structure, and contribute to a culture of excellence, necessary for the development and deployment of the Company’s IMSR plant.
* Can thrive in a fast growing and opportunity business environment, and are capable of flexibility and adaptability at a time of organizational change.
* Have the specific skillset and experience for the following role:
The **Mechanical Engineer/Analyst – Model Development**, under the direction the Mechanical Engineering Manager, is primarily responsible for contributing to the design and analysis of IMSR reactor systems, components and materials through the Detailed Engineering phase.
In particular, the role will include developing and implementing custom Engineering models for predicting the behavior and integrity of reactor materials, components, and systems throughout their operating life under IMSR reactor environmental conditions.
Other responsibilities include:
* Conducting literature and operating experience (OPEX) reviews to support design and model development
* Collaborating with the Research and Development (R\&D) group to translate experimental results into custom Engineering models of components and materials under reactor conditions and to plan new experiments as needed
* Preparing models, calculations and reports for analysis of reactor components (such as graphite core components, core support structures, the reactor vessel, and other in\-core components) including evaluating the effects of irradiation, fatigue, creep, dynamic and static mechanical and thermal loads, and other aspects as needed
* Developing computer codes for building custom analysis tools, automating input/output processing and customizing functionality of commercial software
* Attending and participating in conferences and industry events to stay familiar with and contribute to the development of current codes, standards, and industry best practices
* Interface with external experts and regulatory agencies
**Core Competencies**
* Mechanical and Material model development
* Strong knowledge of solid mechanics and material science fundamentals
* Communication
* Critical Thinking
* Decision Making
* Leadership
* Planning and Organizing
* Problem Solving
* Results Orientation
* Team player with the ability to collaborate and interact with other groups
* Flexible and adaptable to change
**Requirements**
* Degree or diploma in Mechanical Engineering, Materials Engineering, Nuclear Engineering, or alternate degree in a related field
* Minimum 4 years of work experience in mechanical and materials modelling and analysis (relevant graduate studies and academic research experience will be considered, and exceptions may be considered for particularly well\-suited experience of shorter duration)
* Strong theoretical understanding of underlying mechanics of materials and material science fundamentals
* Experience with ANSYS Mechanical or other commercial FEA software (ANSYS Mechanical APDL is preferred)
* Experience with computer programming (Python, C, Fortran, C\+\+, or other) for data pre/post processing or automation/customization of simulations in commercial software
* Knowledge of fatigue, creep, dynamic and static, linear and non\-linear analyses
* Willingness to adapt and learn new approaches and areas of expertise
* Strong communication (both written and verbal) s
