How to Apply for Software Developer

at Terrestrial Energy

🏢 About Terrestrial Energy

Terrestrial Energy is at the forefront of clean energy innovation, developing revolutionary nuclear technology that provides zero-emission power and hydrogen. Their mission to combat climate change with advanced reactor designs offers a unique opportunity to contribute to a sustainable future.

About This Role

As a Software Developer, you'll build full-stack internal applications that directly impact the efficiency and scalability of nuclear engineering processes. Your work on integrations, dashboards, and simulation tools will enable data-driven decisions and accelerate the deployment of clean energy solutions.

💡 A Day in the Life

Your day might start with a standup discussing progress on a new integration between the PLM and simulation tools. You'll then code a Python API endpoint, collaborate with a data scientist to refine a model's output format, and end the day by deploying a frontend update to a dashboard used by engineers.

🎯 Who Terrestrial Energy Is Looking For

  • Has 2+ years of experience building and maintaining production-quality internal tools, with a focus on reliability and user adoption.
  • Proficient in Python and TypeScript, with hands-on experience in React or Vue for frontend development.
  • Comfortable owning features end-to-end, from schema design to deployment and post-release support.
  • Enjoys collaborating with data scientists to productionize models and integrate commercial engineering tools via APIs.

📝 Tips for Applying to Terrestrial Energy

1

Highlight specific internal tools you've built or maintained, emphasizing their impact on engineering workflows.

2

Showcase experience with PLM, MBSE, or SPDM integrations, or mention familiarity with engineering data formats like STEP, XML, or JSON schemas.

3

Provide a code sample or link to a GitHub repo demonstrating full-stack work, especially with Python and React.

4

Mention any experience with simulation orchestration, forecasting, or dashboard development in your resume.

5

Tailor your cover letter to discuss how your work contributes to clean energy goals, not just technical skills.

✉️ What to Emphasize in Your Cover Letter

['Your passion for clean energy and how nuclear technology fits into the broader sustainability landscape.', 'Specific examples of building internal tools that improved efficiency or collaboration between teams.', 'Your experience with API integrations and data pipelines, especially with engineering or scientific software.', 'Your ability to own features end-to-end and collaborate with cross-functional teams like data science.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • Understand Terrestrial Energy's IMSR technology and how it differs from traditional nuclear reactors.
  • Read about their recent partnerships or funding rounds to gauge company growth and stability.
  • Familiarize yourself with typical engineering software in nuclear (e.g., PLM, MBSE tools) and common data exchange formats.
  • Review any public case studies or white papers on their simulation or modeling approaches.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a time you built an internal tool from scratch. What was the architecture, and how did you ensure adoption?
2 How would you design an API to integrate a PLM system with a simulation orchestration tool?
3 Explain your approach to testing and monitoring a productionized model in collaboration with data scientists.
4 Given a requirement for a real-time dashboard, how would you choose between React and Vue, and what data flow would you implement?
5 How do you prioritize features when building internal tools with multiple stakeholders?
