Job Description

The Senior Mechanical Engineer will lead the design, development, and testing of mechanical systems for ocean-based energy devices, ensuring durability and reliability in harsh marine environments while collaborating with multidisciplinary teams to deliver innovative hardware solutions.

Key Responsibilities

Own the mechanical integration of electronics throughout the product lifecycle, including concept generation, detailed design, prototyping, testing, and production release.
Design and optimize mechanical systems for PCBs and electronic subassemblies, including enclosures, chassis, brackets, and mounting systems for marine conditions.
Create and manage detailed 3D CAD models, 2D drawings, GD&T, tolerances, and BOMs for internal and vendor fabrication.
Engineer for complex constraints such as airflow, EMI shielding, shock, and vibration, ensuring manufacturability and reliability.
Prototype and test designs, including hands-on building and iteration to validate form, fit, and function.
Select appropriate materials and manufacturing processes like sheet metal, injection molding, CNC, and casting based on performance, reliability, and cost.
Collaborate with electrical, firmware, product, and industrial design teams to develop integrated systems.
Identify risks early and solve problems proactively through testing, feedback, and iteration.

Requirements

A degree in mechanical engineering, aerospace engineering, or a related discipline.
5 years of experience designing and packaging electronic systems for production, with a proven record of fielded products in your portfolio.
Expertise in 3D CAD, ideally Siemens NX, with strong modeling, surfacing, and drawing creation skills.
Proficient in GD T and experienced in tolerance stack-ups for mechanical-electrical integration.
A track record of delivering real hardware through multiple design-build-test-release cycles.
Ability to work independently and drive projects forward in a fast-paced, interdisciplinary environment.
Deep understanding of materials, manufacturing methods, and environmental durability.
Exceptional attention to detail and a strong commitment to getting the hard things right.
Travel to vendors and test sites as needed.
Intermittently able to work longer hours and weekends to support critical needs.
