Panthalassa Tech Stack

Open-ocean energy nodes powering offshore compute and renewable fuels

Renewable Energy Power Generation Portland, Oregon 51–200 employees Privately Held
panthalassa.com LinkedIn

Panthalassa is building ocean-based energy nodes that capture open-ocean power to run compute at sea and produce renewable fuels for shore delivery. Its stack pairs heavy simulation tooling (Nastran, OrcaFlex, STAR-CCM+, OpenFOAM, Fluent) with manufacturing quality frameworks (APQP, PPAP, 8D, MES), showing a hardware company moving from prototype engineering into factory ramp. Hiring is senior-weighted and engineering-heavy, though velocity is decelerating.
