About the Company
We are a renewable energy and ocean technology company committed to rapidly developing and deploying technologies that will ensure a sustainable future for Earth by unlocking the vast energy potential of its oceans. Our focus is on capturing civilizational levels of ultra-low-cost renewable energy for applications including computing and affordable renewable fuels delivered to shore.
The company is a public benefit corporation headquartered in Portland, Oregon and backed by leading venture capitalists, philanthropic investors, university endowments, and private investment offices. We operate as an idea meritocracy in which the best ideas change the company’s direction on a regular basis.
Our staff have worked at organizations such as SpaceX, Blue Origin, Boeing, Tesla, Apple, Virgin Orbit, Astra, Google, Amazon, Microsoft, New Relic, Bridgewater, Raytheon, Disney Imagineering, and the US Army and Air Force, as well as research universities, startups, and small companies across a range of industries.
About the Job
As a Fluid Dynamicist, you will help develop, validate, and apply the fast-running physics-based tools that drive Panthalassa’s design, optimization, and fleet deployment decisions. You will work with our Principal Fluid Dynamicist and collaborate closely with computational fluid dynamics (CFD), controls, optimization, mechanical engineering, metocean, and fleet performance teams.
This role focuses on reduced-order and mid-fidelity marine hydrodynamics tools, including boundary element method (BEM) models, fleet deployment simulators, OrcaFlex models, metocean-driven performance analyses, and external-function links to our time-domain device simulators. You will write production-quality engineering code, run analyses, process results, communicate findings, debug model behavior, and identify opportunities to improve our fast-running simulation stack.
The ideal candidate has strong fundamentals in marine hydrodynamics, understands BEM concepts, is highly capable in Python, and can move fluidly between theory, code, simulation results, and engineering decisions. This person will independently own major modeling and simulation workstreams.
Candidates should have strong interpersonal skills and be able to thrive in a creative, scrappy, and collaborative environment in which the best ideas change the company’s direction on a regular basis. You will own your designs cradle-to-grave, from first concept through fabrication and deployment at sea. If you are an excellent engineer, regardless of your background, we want you to apply.
Responsibilities
- Develop, maintain, validate, and apply fast-running hydrodynamics models used for design, optimization, controls, and fleet deployment analysis.
