Senior Structural Engineer

Our offices, lab, and shop are located in Portland, Oregon.

• 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 Senior Structural Engineer, you will spearhead the structural analysis of numerous mechanical systems and help develop innovative methods and tools to select the best designs across a design space of millions of possibilities.
• You will be a key part of the team responsible for the development of algorithms, pipelines, and other software to drive efficient structural analysis and cost estimation. You will also play a critical role in developing best practices and approaches for structural analysis as well as performing detailed stress and fatigue analysis of point designs. We expect you to be especially strong in structural analysis and coding, and to gravitate toward first-principles/fundamental-physics when solving problems.
• 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.
• Develop algorithms/software that support the structural sizing of an entire design space in an automated way, allowing millions of end points to be accurately evaluated.
• Work with Nastran input and output files for FEA analyses and scripts.
• Generate and evaluate load spectra from test and simulation results.
• Perform stress hand‑calculations and fatigue/damage tolerance analyses for various designs.
• Serve as the stress analyst for core technology subsystems, which could include device primary structure, pressure- and seawater‑tolerant electronics packaging, drive trains, deployment features, lab‑based testing apparatuses, piping/cable routing and layout, and ground‑support equipment.
• Drive the structural design of various systems to ensure an efficient end‑product that is sufficiently robust and supports an optimal manufacturing process.
• Utilize Femap, NX‑Simcenter, and internal FEA tools to perform linear, non‑linear, and dynamic analyses of large assemblies.
• Use a CAD software design package (NX) and PDM tool (Teamcenter) to facilitate design changes and stress evaluation.
• Lead and participate in design reviews with the internal team and interface with external fabricators and vendors.

• An undergraduate degree in Mechanical Engineering or equivalent.
• Wide‑ranging experience and advanced knowledge in structural analyses techniques including classical hand analyses and computer analysis tools.
• Proven experience evaluating numerous parts and assemblies that have undergone structural testing and seen service.
• Working knowledge of FEA codes and pre‑ & post‑processing (Nastran preferred).
• Solid coding abilities, with experience using Python, Julia, Mathematica, or another similar programming language for data review and analysis.
• Strong written and verbal communication skills.
• Proven ability to work in a team environment.
• Confidence working independently to drive a project forward.
• A work history encompassing at least five design, build, test, and deploy cycles for different projects.
• Ability to work in a fast‑paced, self‑starting, and demanding atmosphere.
• Advanced degree in mechanical engineering, structural engineering, aerospace engineering, naval architecture, or a related field, or 5 years additional experience in lieu of an advanced degree.
• At least 5 years in a similar role.
• Experience evaluating large, welded steel structures in dynamic environments.
• Intimate familiarity with Nastran input decks.
• Direct involvement in structural verification testing.
• Excellent coding abilities.
• Extensive experience with Femap.
• Experience with NX/Teamcenter.
• Hands‑on hardware experience performing design, fabrication, assembly and testing.
• Curiosity to learn and a passion for continuous improvement.
• Solid understanding of technical projects from the details to the big picture.
• Strong interpersonal, organizational, and presentation skills.
• The above qualifications are desired, not required. We encourage you to apply if you are a strong candidate with only…
