How to Apply for Senior Computational Engineer

at Panthalassa

🏢 About Panthalassa

Panthalassa is at the forefront of sustainable energy, harnessing the immense power of Earth's oceans. Their mission to revolutionize marine energy offers a unique opportunity to work on cutting-edge technology that directly impacts global renewable energy goals. As a remote-first company, they value innovation and collaboration across disciplines.

About This Role

As a Senior Computational Engineer, you will lead high-fidelity CFD simulations to optimize marine system designs, directly influencing the performance and viability of ocean energy technologies. Your work will bridge simulation and real-world performance, accelerating Panthalassa's path to commercial success. This role offers the chance to shape computational workflows from the ground up.

💡 A Day in the Life

A typical day might start with reviewing simulation results from overnight runs, then debugging a convergence issue in an OpenFOAM case. You'll collaborate with the design team to discuss how simulation insights can improve the next prototype, and spend part of the afternoon developing a Python script to automate post-processing. You'll also present findings in a cross-functional meeting, translating technical uncertainties for the broader team.

🎯 Who Panthalassa Is Looking For

  • An expert in CFD with extensive hands-on experience in OpenFOAM, Star-CCM+, or Helyx, specifically applied to marine or hydrodynamic systems.
  • A problem-solver who can diagnose and resolve complex CFD issues, with a strong grasp of verification and validation principles.
  • Comfortable working in a fast-paced startup environment, taking ownership of simulation pipelines and automation.
  • A collaborative communicator who can translate simulation results and uncertainties for non-specialist teams.

📝 Tips for Applying to Panthalassa

1

Highlight specific projects where you used OpenFOAM, Star-CCM+, or Helyx to solve real engineering problems, especially in marine or hydrodynamics contexts.

2

Showcase your experience with automation and workflow development (e.g., Python scripting, pipeline tools) for CFD validation.

3

Quantify your impact: mention how your simulations improved design performance, reduced costs, or accelerated timelines.

4

Tailor your resume to emphasize marine hydrodynamics and physics-based modeling, even if your background is in aerospace or mechanical engineering.

5

In your cover letter, explicitly connect your skills to Panthalassa's mission of ocean energy and mention your enthusiasm for sustainable energy.

✉️ What to Emphasize in Your Cover Letter

["Your passion for sustainable energy and ocean technologies, and why Panthalassa's mission resonates with you.", 'Specific examples of leading CFD validation workflows and improving simulation accuracy for real systems.', 'Your ability to work cross-functionally and communicate technical results to diverse teams.', 'Your experience with automation and how you can help Panthalassa close the loop between predicted and measured performance.']

🔍 Research Before Applying

To stand out, make sure you've researched:

  • → Study Panthalassa's technology: understand their specific ocean energy converters and current development stage.
  • → Read recent publications or news about Panthalassa's pilot projects and partnerships.
  • → Familiarize yourself with common CFD challenges in marine hydrodynamics (e.g., free surface, turbulence, cavitation).
  • → Check their LinkedIn or team page to understand the company culture and key team members.

💬 Prepare for These Interview Topics

Based on this role, you may be asked about:

1 Describe a time you debugged a CFD simulation that was not matching experimental data. What steps did you take?
2 How do you approach verification and validation for a new marine system design?
3 Walk us through your experience with OpenFOAM or Star-CCM+ for hydrodynamic simulations.
4 How would you design an automated CFD validation pipeline for a tidal turbine?
5 What are the key challenges in modeling ocean energy systems, and how have you addressed them?

⚠️ Common Mistakes to Avoid

  • Avoid generic statements about CFD without linking to marine or hydrodynamic applications.
  • Don't overlook the importance of automation and scripting; they want someone who can build pipelines, not just run simulations.
  • Avoid being overly theoretical; emphasize practical, end-to-end simulation experience for real engineering systems.
