Requirements
  • An undergraduate degree in Mechanical Engineering or equivalent
  • Wide-ranging experience and advanced knowledge in structural analyses techniques including classical hand analyses and computer analysis tools
  • Proven experience evaluating numerous parts and assemblies that have undergone structural testing and seen service
  • Working knowledge of Finite Element Analysis codes and pre- and post-processing (Nastran preferred)
  • Solid coding abilities with experience using Python, Julia, Mathematica, or another similar programming language for data review and analysis
  • Strong written and verbal communication skills
  • Proven ability to work in a team environment
  • Confidence working independently to drive a project forward
  • A work history encompassing at least five design, build, test, and deploy cycles for different projects
  • Ability to work in a fast-paced, self-starting, and demanding atmosphere
Responsibilities
  • Develop algorithms and software that support the structural sizing of an entire design space in an automated way, allowing millions of end points to be accurately evaluated
  • Work with Nastran input and output files for finite element analyses and scripts
  • Generate and evaluate load spectra from test and simulation results
  • Perform stress hand-calculations and fatigue/damage tolerance analyses for various designs
  • Serve as the stress analyst for core technology subsystems, which could include device primary structure, pressure- and seawater-tolerant electronics packaging, drivetrains, deployment features, lab-based testing apparatuses, piping/cable routing and layout, and ground-support equipment
  • Drive the structural design of various systems to ensure an efficient end-product that is sufficiently robust and supports an optimal manufacturing process
  • Utilize Femap, NX-Simcenter, and internal finite element analysis tools to perform linear, non-linear, and dynamic analyses of large assemblies
  • Use a computer-aided design software package (NX) and product data management tool (Teamcenter) to facilitate design changes and stress evaluation
  • Lead and participate in design reviews with the internal team and interface with external fabricators and vendors
Desired Qualifications
  • Advanced degree in mechanical engineering, structural engineering, aerospace engineering, naval architecture, or a related field, or five years of additional experience in lieu of an advanced degree
  • At least five years in a similar role
  • Experience evaluating large, welded steel structures in dynamic environments
  • Intimate familiarity with Nastran input decks
  • Direct involvement in structural verification testing
  • Excellent coding abilities
  • Extensive experience with Femap
  • Experience with NX/Teamcenter
  • Hands-on hardware experience performing design, fabrication, assembly and testing
  • Curiosity to learn and a passion for continuous improvement
  • Solid understanding of technical projects from the details to the big picture
  • Strong interpersonal, organizational, and presentation skills

Panthalassa designs autonomous, floating energy nodes that harvest power from open-ocean waves. Each node is a solid sphere about 50 meters in diameter with a neck extending 60–70 meters below the surface; wave motion pumps seawater into a pressurized reservoir and drives electricity through a single turbine for onboard use. The system emphasizes a simple, rugged solid‑state design and offshore, autonomous operation, with modular, marine-based energy generation aimed at a high capacity factor (up to 90%). Its goal is reliable, ocean-based power for on-site applications and scalable sea-based energy infrastructure for clean power and fuels, supported by funding from investors like Founders Fund, Gigascale Capital, and Lowercarbon Capital.

Simplify Jobs

Simplify's Take

What believers are saying

  • Onboard compute addresses AI data-center grid and siting constraints.
  • Pilot manufacturing near Portland supports faster prototyping and deployment.
  • Fleet architecture enables modular scaling into a single data-center network.

What critics are saying

  • Satellite backhaul constrains latency, bandwidth, and workload suitability.
  • Hurricanes, salt spray, and constant motion threaten offshore hardware reliability.
  • Commercial systems are planned for 2027, leaving execution risk before revenue.

What makes Panthalassa unique

  • Autonomous ocean nodes generate power onboard, avoiding land transmission losses.
  • Garth Sheldon-Coulson brings AI research experience; Brian Moffat brings ocean-energy expertise.
  • Panthalassa combines renewable power, embedded compute, storage, and satellite connectivity.
