Job Description

This is an on-site position. Our offices, lab, and shop are located in Portland, Oregon . Expect periodic travel to deployment sites and time on the shop floor and on the water.

Key Responsibilities

We are developing a core technology, the “Node”, 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 Mechanical Engineer, Structures you will own the design, development, and analysis of Node structures and subsystems from concept through deployment at sea, ensuring their designs are simple, manufacturable, and reliable in demanding offshore environments.
This position requires a highly motivated, hands-on engineer who thrives in ambiguity, can execute with autonomy, and is eager to take on end-to-end ownership from early architecture and trade studies to prototype testing to final build at our factory. You will make fast decisions, solve tough problems in the moment, and own projects from start to finish. The job requires you to build deep knowledge in load paths, design for manufacturability, welded structures, subassembly design, and fabrication. We expect you to be especially strong in analysis and to gravitate toward first-principles, fundamental-physics approaches to problem solving.
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.
Own the design, analysis, and development of Node structures, secondary structures, and subassemblies
Perform structural and dynamic analysis (FEA, hand calcs, margins, etc.) to validate designs including fatigue analysis
Create and maintain component and assembly CAD models
Create detailed component and assembly drawings with a strong grasp of geometric dimensioning and tolerancing (GD&T) and tolerance stack-ups
Drive design trade studies and engineering reviews, helping document decisions and technical findings
Drive material selection and corrosion-conscious detailing for long-duration seawater service
Plan and support structural validation testing, from coupon/component tests through prototype and at-sea trials
Collaborate with offshore operations, technicians, and manufacturing teams to ensure designs are practical and buildable

Requirements

Bachelor’s or Master’s degree in Mechanical Engineering, Aerospace Engineering, Naval Architecture, or a related technical field
3+ years of experience in mechanical or structural design engineering, including internships, research, or project work
Demonstrated 3D CAD modeling experience
Strong structural analysis fundamentals (load paths, hand calculations, FEA)
Exposure to metallic structural design, GD&T, drawing creation, integration, and testing
Strong communication skills and the ability to work collaboratively across multidisciplinary teams in a fast-paced environment
Master’s degree in Mechanical Engineering, Aerospace Engineering, Naval Architecture, or a related technical field
3+ years of professional experience designing and analyzing primary or secondary structures
Proficiency with NX/Teamcenter
Proficiency with NASTRAN/Simcenter
Experience in a startup or agile development environment
Familiarity with marine/offshore engineering fundamentals
Exposure to relevant codes/standards (e.g., DNV, ABS, AWS D1.1, BPVC)
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 $105,000 - $145,000.
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).
