CAD Designer

About the Company Panthalassa is a renewable energy and ocean technology company operating as a public benefit corporation. We are 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. About the Role We are seeking a CAD Designer to bridge the gap between initial structural concepts and production-ready engineering releases. In this role, you will focus heavily on CAD execution, assembly management, and technical documentation for our core technology, the “Node” —a device designed to generate energy and survive for decades in the world's harshest offshore environments. You will own the “last-mile” engineering definition that turns structural concepts into NX models, drawings, and releases that the shop can build without guessing. You’ll work at the intersection of design, analysis, and fabrication—making clean assemblies, clear drawings, and a PLM structure that matches how we actually build and service hardware. Our staff have worked at organizations such as SpaceX, Blue Origin, Stoke, Boeing, Virgin Orbit, Virgin Galactic, 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. We are backed by leading venture capital firms, private investors, philanthropic investors, and endowments. We strive to be the best engineering team on the planet. If you are an excellent engineer and technical leader, regardless of your background, we want you to apply. Key Responsibilities NX Modeling & Assembly: Develop and maintain expert-level 3D CAD component models and large-scale mechanical assemblies within Siemens NX. Drawing & Detailing: Lead the creation of complex fabrication and assembly drawings, ensuring absolute clarity, accuracy, and technical rigor. Structural Documentation: Personally own the detailed documentation and drafting for large-scale, safety-critical welded steel structures and subassemblies. PLM & Lifecycle Management: Integrate all design data tightly within Siemens Teamcenter PLM to support manufacturing accuracy and streamlined engineering release processes. Cross-Functional Collaboration: Partner closely with structural analysts, manufacturing teams, and shop floor technicians to optimize designs for manufacturability and marine service. Release Ownership: Drive clean engineering releases (ECR/ECO or equivalent), maintain configuration discipline, and keep definition aligned with what’s being built. Standards & Libraries: Help establish and maintain drawing/modeling standards, templates, and common details so the next release is faster and more consistent than the last. Required Qualifications Education/Experience: Associates Degree, Bachelor’s Degree, or 5+ years relevant professional CAD experience in a similarly complex industry CAD Expertise: Strong professional experience in 3D CAD modeling and drafting Technical Standards: Knowledge of relevant engineering standards such as ASME Y14.100. Structural Experience: Proven track record in the design detailing and documentation of metallic structures, load paths, and large-scale welded assemblies. Professional Mindset: High attention to detail with a meticulous approach to technical documentation, alongside the ability to thrive in a fast-paced, collaborative startup environment. Desired Attributes Bachelor’s degree in Mechanical Engineering, Aerospace Engineering, Naval Architecture, or a related technical field. Extensive CAD experience on Siemens NX and Teamcenter PLM. Ability to apply understanding of Geometric Dimensioning and Tolerancing (GD&T) and tolerance stack-up analysis to ensure components are practical and buildable. Familiarity wit
