About the Job

Requirements

  • A bachelor's degree in Naval Architecture, Marine Engineering, Ocean Engineering, or a similar field.
  • At least 2 years of professional experience performing stability, seakeeping, and weights-and-balances analyses in a naval architecture role.
  • Professional experience using GHS or equivalent vessel-stability software, such as Maxsurf or Orca3D.
  • Professional experience using a parametric CAD package, such as NX or SolidWorks, to model parts and assemblies and generate fabrication drawings.
  • Strong written and verbal communication skills.
  • Ability to provide guidance and technical material to engineers, designers, technicians, and suppliers, and to receive and incorporate their guidance and technical information into your approach.
  • Confidence working independently to drive a project forward.

Responsibilities

  • Perform and maintain stability and weights-and-balances analyses using GHS and other internal tools.
  • Develop and release Node structure drawings, driving drawing releases to keep fabrication ungated.
  • Perform detailed design of mechanical, structural, and support subsystems, such as human access and shoreside support.
  • Determine requirements for the Node program relating to stability, seakeeping, mooring, structures, and marine operations.
  • Drive hydrodynamic-load investigations involving multidisciplinary teams.
  • Contribute to OrcaFlex analyses and hydrodynamic studies.
  • Drive Node program strategies for corrosion mitigation and biofouling prevention.
  • Work closely with the Marine Operations Engineering team to develop concepts of operations and ensure Nodes can be safely and reliably deployed and recovered at sea.
  • Contribute to and participate in external communications with regulators, insurance partners, and marine surveyors.
  • Lead and participate in design reviews with the internal team and interface with external fabricators and vendors.
  • Travel to vendors and test sites as needed.
  • Intermittently work longer hours and weekends to support critical needs.

Desired Qualifications

  • Experience working with regulatory and classification organizations on novel projects.
  • Experience with Reynolds-averaged Navier–Stokes (RANS) theory and tools such as Star-CCM+ or OpenFOAM.
  • Shipyard manufacturing or repair experience.
  • Experience using high-end hydrodynamics analysis software to estimate vessel motions, such as Ansys AQWA, Maxsurf Motion, or WAMIT.
  • Proficiency with OrcaFlex.
  • At least 2 years of 3D CAD modeling experience.
  • Experience with NX and Teamcenter.
  • Experience with Rhino3D CAD software.
  • Experience with finite element analysis software packages such as NX NASTRAN or FEMAP.
  • Experience using Python, Julia, MATLAB, or a similar programming language for data review and analysis.
  • Experience using AI tools such as Cursor, Claude, or Copilot for programming and analysis workflows.
  • Prior experience working in a marine environment or with marine vessels.
  • Proficient and frequent use of hand calculations.
  • Ability to work in a fast-paced, self-starting, and demanding atmosphere.
  • Curiosity to learn and passion for continuous improvement.
  • Solid understanding of technical projects from details to the big picture.
  • Strong interpersonal, organizational, and presentation skills.

About the Company

Panthalassa

Autonomous floating wave-energy generators for power

Panthalassa builds autonomous, floating energy nodes that harvest power from open-ocean waves. Each node is a 50-meter-diameter solid sphere with a 60–70 meter downward neck; waves move the node to pump seawater into a pressurized reservoir, which runs through a turbine to generate electricity, aiming for continuous power with a high capacity factor and energy kept on board for off-grid use. The design is simple and rugged, supports offshore operation, and focuses on modular, marine-based energy rather than centralized, onshore plants. Its goal is to provide reliable ocean-based power for on-site needs and to enable scalable sea-based energy infrastructure for clean power and fuels like green hydrogen.
