Join us on our mission to make clean energy available to all

As the Mechanical Engineer, Marine Operations, you will drive the development of essential mechanical assets from cradle to grave. You will conduct trade studies to identify optimal system architectures, perform engineering analyses, create detailed designs, and bring these designs to operational readiness. Additionally, you will support offshore operators utilizing these tools through initial commissioning and sustaining engineering.

As the Mechanical Engineer – Concepts & Structural Configuration, you will play a critical role in developing our core technology—the Node—which is designed to operate for years in the harshest ocean conditions without human maintenance or intervention. You will bring deep expertise in conceptual layout, system configuration, and structural design to ensure our Nodes are simple, robust, and manufacturable, working alongside senior structural engineers, analysts, and mechanical designers to evaluate early-stage system architectures, create layout models in NX, perform structural sizing and analysis, and translate scale model test results into resilient real-world systems.

As the Lead Mechanical Engineer, Turbomachinery, you will lead the technical vision, execution, and continuous improvement of the rotating machinery that turns fluid power into electrons. This is a roll-up-your-sleeves leadership role in which you'll prototype, build, and troubleshoot alongside world-class engineers and technicians.

As a Senior Mechanical Engineer focused on Core Electronics and Systems Integration, you will own the complete mechanical lifecycle of our core electronic systems- from whiteboard to waves. This is a hands-on, high-impact role where you will lead the design, prototyping, integration, and deployment of enclosures and mechanical assemblies critical to our power generation and conversion units.

We are developing a core technology that will operate in the worst conditions the world’s oceans have to offer for years at a time without human maintenance or intervention. As a Senior Mechanical Engineer, you will spearhead the design of numerous mechanical components and assemblies that must withstand extreme loads and a harsh ocean environment.

As a Senior Software Engineer, you will contribute to the design, development, and optimization of high-performance telemetry and command systems that drive cutting-edge marine autonomy solutions. This role combines technical expertise with strategic thinking, requiring you to help build scalable APIs and data storage systems, rapidly iterate on operational UIs, and integrate with diverse external systems. Your work will directly impact operational efficiency, innovation, and the delivery of state-of-the-art maritime technologies. This team’s responsibilities include both the backend (Elixir) and frontend (Phoenix LiveView) of shore systems.

As a Senior Computational Fluid Dynamicist, you will execute critical components of our CFD modeling and simulation strategy. You will take ownership of the full simulation workflow and play a central role in shaping simulation and process automation methodologies, evaluating and validating the performance of novel marine systems, and mentoring junior engineers. You’ll help us push the boundaries of marine CFD in a highly dynamic, mission-driven environment. 

As the Shipping & Receiving Manager, you will lead the day-to-day logistics operations at our Portland, OR facility. You will be responsible for ensuring the accurate and timely flow of materials into and out of the organization, maintaining clean and reliable inventory records, and building the physical and digital infrastructure to support future scale.

As our Director of Accounting & Corporate Controller, you will lead financial operations during a critical growth phase as we scale from R&D to mass production and commercial deployment. You’ll build scalable systems and controls, establish reporting processes that support rapid decision-making, and provide financial insights that help leadership execute on ambitious goals. This is a hands-on role ideal for a builder ready to architect and own our accounting infrastructure from the ground up.

As Office Manager, you will own, execute and optimize the day-to-day operations of our workplace. You’ll lead vendor relationships, manage office systems, oversee safety and access control, and continuously improve how we use and care for our shared space. You will also serve as the face of our headquarters for visitors and staff alike, creating a clean, functional, and welcoming environment.

As a Senior Technical Recruiter, you will help build the teams that enable Panthalassa’s mission. You will manage full-cycle recruiting for technical, engineering, and scientific roles while working closely with a recruiting program manager and other teammates. This role is designed for someone who thrives as a thought partner—bringing expertise, ideas, and execution.

Please get in touch even if you don’t see a position. We’re always on the lookout for excellent talent.
