About the Job
We are seeking a Senior Mechanical Engineer, Fluid Systems to play a critical role in the design and development of the fluid systems that power our core technology, the “Node.” The Node will operate in the worst conditions the world’s oceans have to offer for years at a time without human maintenance or intervention, and fluid systems are central to its performance and reliability.
In this role, you will own the design and delivery of critical fluid subsystems and components, working within the broader system architecture to ensure performance, reliability, and manufacturability. You will contribute deep technical expertise across design, analysis, testing, and deployment, partnering closely with mechanical design, manufacturing, and test teams.
This role is ideal for a highly capable engineer who thrives in hands-on technical work, enjoys solving complex problems, and is motivated to build robust, real-world systems. You will have significant ownership over your work while collaborating closely with senior technical leaders to refine system-level design decisions.
Candidates should have strong interpersonal skills and be able to thrive in a creative, scrappy, and collaborative environment in which the best ideas change the company’s direction on a regular basis. You will own your designs cradle-to-grave, from first concept through fabrication and deployment at sea. If you are an excellent engineer, regardless of your background, we want you to apply.
Responsibilities
- Own the design and development of critical fluid subsystems and components across all phases (concept through deployment)
- Perform detailed design and analysis, including material selection, sizing, and system integration
