This position will allow occasional flexibility for a hybrid schedule, but with the expectation that most work will be onsite as a leader of a well-integrated team.

The ideal Mechanical Engineer candidate for this role would be detail oriented and able to help identify design issues during the development phase of a program. They should possess a solid background in electro-mechanical integrated systems, preferably with experience in material science, spacecraft systems, mechanisms, and mechanical design. Experience in manufacturing environment would also be desirable for this position. This candidate should be a proactive problem solver who doesn’t wait to be assigned tasks but instead actively identifies and solves them, proposing solutions as opposed to simply identifying problems. This position will also be supervisory, with an expectation to lead and mentor junior engineers.

Primary Responsibilities

  • Mechanical design, from overall system level to individual piece parts, as well as tolerance stack-ups and various types of analysis.
  • Technical leadership of a fast-paced design effort, including tasking of more junior engineers
  • Lead design reviews, run analysis, and define hardware test plans.
  • Build prototypes, analyze failures, and transition successful projects into production.
  • Breaking down large, complex assemblies into a logical part flow of subassemblies and sub-processes.

Basic Qualifications

  • Bachelor’s degree plus twelve or more years of relevant work experience.
    • Additional experience and technical training may substitute for degree requirement.
  • Demonstrated ability to creatively integrate and deliver hardware in a resource-constrained environment.
  • Demonstrated in-kind or direct team leadership skills, with backing examples.
  • Must possess the ability to understand new concepts quickly; apply them accurately; organize, schedule, and coordinate work phases and determine the appropriate approach at the task level or, with assistance, at the project level to provide solutions to a range of complex problems.
  • Must have strong communication (written and verbal) and interpersonal skills.
  • Ability to work independently and as part of a multi-disciplined team; able to perform complex tasks applying engineering first principles.
  • Experience and high proficiency with GD&T and performing tolerance stack up analysis.
  • Demonstrated proficiency with CAD based software such as SolidWorks.
  • U.S. Citizenship
  • Candidate must reside in the San Diego, CA area or be willing to relocate to the area.
  • Current Secret clearance and eligibility for a Top Secret/SCI clearance is required.

Preferred Qualifications

  • Current TS/SCI clearance is preferred
  • Five years of experience in space product (space vehicle or payload) design, manufacturing, or support that includes broad demonstrated experience in electrical, mechanical, software, and manufacturing engineering including product design, validation, test, troubleshooting, repair, and support.
  • Experience with optical-mechanical systems.
  • Experience with designing for manufacturing
  • Experience working in a fast paced, dynamic environment on projects that are both R&D and low volume production.
  • Experience with developing tests for component level qualification.
  • A material science proficiency in selecting material for strength, thermal expansion, and other properties.
  • Experience with performing thermal and structural analysis.
  • Experience with validating system requirements.
  • Personal experience physically manufacturing and assembling hardware.
  • Experience working in a clean room environment.
