  • 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 specifications, 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 iterative design improvements.

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.
