Intern – Digital Twin

TITLE: Intern – Digital Twin

LOCATION: Bellevue, WA, USA

TerraPower is a nuclear technology company based in Bellevue, Washington. At its core, the company is working to raise living standards globally through a more affordable, secure and environmentally friendly form of nuclear energy along with innovations in medical isotopes to improve human health. In 2006, TerraPower originated with Bill Gates and a group of like-minded visionaries who evaluated the fundamental challenges to raising living standards around the world. They recognized energy access was crucial to the health and economic well-being of communities and decided that the private sector needed to take action and create energy sources that would advance global energy deployment. TerraPower’s mission is to be a world leader in new nuclear technologies, while developing innovators and future leaders in the nuclear field. As a result, the company’s activities in the fields of nuclear energy and related sciences are yielding significant innovations in the safety and economics of nuclear power, hybrid energy and medical applications – all for significant human health benefits.

TerraPower is seeking to hire highly motivated and forward-thinking professionals who are interested in focusing on advanced nuclear reactor research and development and influencing change within the nuclear power landscape and bringing forward the critical production of medical isotopes. TerraPower is an Equal Opportunity Employer. We do not discriminate in hiring on the basis of sex, gender identity, sexual orientation, race, color, religious creed, national origin, physical or mental disability, protected Veteran status, or any other characteristic protected by federal, state, or local law. In addition, as a federal contractor, TerraPower has instituted an Affirmative Action Plan (AAP) in an effort to proactively recruit, hire, and promote women, minorities, disabled persons and veterans.

Intern – Digital Twin

The Digital Twin Internship offers students the opportunity to contribute to TerraPower’s efforts to develop next-generation digital capabilities for advanced reactor systems. As part of the Digital Products & AI team, you will build and test simplified digital-twin simulations that represent the behavior and degradation of reactor subsystems — helping define how predictive-maintenance insights could be generated from engineering models. This role blends simulation, data modeling, and systems thinking, giving students experience at the intersection of engineering and digital technology.

What you’ll gain:

- Hands-on experience building and analyzing simulation-based digital-twin models.

- Exposure to predictive-maintenance methods and how digital twins support lifecycle reactor management.

- Mentorship from senior engineers, data scientists, and product leaders driving TerraPower’s digital transformation.

- Insight into how simulation and modeling accelerate design, reduce risk, and prepare for future operational readiness.

Responsibilities

- Develop or adapt basic subsystem simulations (e.g., pumps, heat exchangers) to model normal and degraded operating conditions.

- Explore how simulation outputs can represent early indicators of equipment health or performance degradation.

- Visualize and interpret model results to identify patterns useful for future predictive-maintenance analytics.

- Document modeling assumptions, key parameters, and lessons learned.

- Present findings in a capstone presentation to TerraPower’s Digital Products & AI team.

Key Qualifications and Skills

- Current undergraduate or graduate student in Mechanical Engineering, Nuclear Engineering, Computer Science, Data Science, or Systems Engineering.

- Coursework or project experience in:

o Simulation or system modeling (e.g., COMSOL, ANSYS, MATLAB/Simulink, OpenFOAM, or Python).

o Basic programming or data analysis (Python, MATLAB, or similar).

o Familiarity with reliability engineering or degradation modeling is a plus

- Strong analytical, problem-solving, and communication skills.

- Interest in digital-twin concepts and predictive-maintenance technologies.

- The successful candidate will possess a high degree of trust and integrity, communicate openly and display respect and a desire to foster teamwork.
