This is an on-site position. Our offices, lab, and shop are located in Portland, Oregon.
Key Responsibilities
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. If you are an excellent engineer, regardless of your background, we want you to apply.
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
Collaborate with staff and senior engineers to refine system architecture and integration strategies
Participate in design reviews and contribute to technical decision-making
Work closely with internal teams and external vendors to ensure high-quality fabrication and assembly
Produce clear engineering documentation, including drawings and GD&T
Partner with testing teams to validate performance and iterate based on test and field data
Troubleshoot and resolve issues in development, test, and deployment environments
Mentor junior engineers and contribute to a culture of technical excellence
Requirements
Degree in mechanical engineering, aerospace engineering, naval architecture, marine engineering, or a related field
5+ years designing components and subsystems for fluid systems across a range of applications
5+ years of 3D CAD modeling experience
Experience with complex, safety-critical, or high-performance fluid systems
Strong engineering fundamentals, including hand calculations and simulation tools
Strong written and verbal communication skills
Ability to collaborate effectively with engineers, technicians, and external partners
Experience contributing to multiple design-build-test cycles for complex systems
Advanced degree in a relevant engineering field or equivalent additional experience
Proficiency with NX/Teamcenter or similar CAD/PLM tools
Familiarity with marine or offshore systems (e.g., hydraulics, welded structures, mechanical assemblies)
Experience with programming tools such as Python, Julia, or Mathematica
Knowledge of engineering standards such as ASME Y14.5
Strong organizational and problem-solving skills
Ability to operate effectively in a fast-paced, iterative environment
Travel to vendors and test sites as needed.
Intermittently able to work longer hours and weekends to support critical needs. While we expect a lot of each other, we also offer a high degree of autonomy and work-life balance.
Benefits & Perks
If hired for this full-time role, you will receive:
Cash compensation of $155,000 – $205,000.
Equity in the company. We’re all owners and if we’re successful, this equity should be far and away the most valuable component of your compensation.
A benefits package that helps you take care of yourself and your family, including:
Relocation assistance to facilitate your move to Portland (if needed).
