at Canadian Solar (North America)

🏢 About Canadian Solar (North America)

Canadian Solar is a global leader in solar energy, having delivered over 55 GW of modules worldwide. Joining means contributing to a mission-driven company that's at the forefront of the renewable energy transition, with a strong emphasis on innovation and sustainability.

About This Role

As a Senior Control Engineer, you'll lead the development of HIL test environments for cutting-edge PCS and inverter systems, ensuring their reliability and performance. Your work directly impacts product quality and field issue resolution, making you a key player in advancing solar energy technology.

💡 A Day in the Life

A typical day might involve setting up a HIL test to validate a new inverter control algorithm, reviewing automated test results, and collaborating with firmware engineers to debug a field issue. You'd also mentor a junior engineer on test script development and attend a cross-functional meeting to discuss product lifecycle improvements.

🎯 Who Canadian Solar (North America) Is Looking For

  • Expert in HIL platforms like OPAL-RT or Typhoon HIL, with hands-on experience setting up real-time simulations for power electronics.
  • Strong background in MATLAB/Simulink model-based design and automation of test scripts for regression suites.
  • 5+ years in PCS/inverter validation, including firmware testing and protection strategy verification.
  • A mentor who can guide junior engineers and collaborate cross-functionally to resolve field issues.

📝 Tips for Applying to Canadian Solar (North America)

1

Highlight specific HIL platforms you've used (e.g., OPAL-RT, Typhoon) and describe complex test setups you've built.

2

Emphasize experience with automated test script development (e.g., Python, MATLAB) for regression testing.

3

Mention any work with PCS or inverter firmware validation, particularly under abnormal conditions.

4

Tailor your resume to show 5+ years of relevant experience; use metrics to quantify impact (e.g., reduced test time by X%).

5

Include a brief note in your cover letter about your familiarity with Canadian Solar's products or market presence.

✉️ What to Emphasize in Your Cover Letter

['Your deep expertise in HIL testing and real-time simulation for power electronics.', 'Your ability to mentor junior engineers and drive continuous improvement in validation processes.', "Your commitment to renewable energy and alignment with Canadian Solar's mission.", "Specific examples of how you've resolved field issues or improved firmware reliability through HIL testing."]
