About the Job

Requirements

  • Four to six years of relevant experience in mechanical design, electro-mechanical systems, electronics packaging, optical systems packaging, or product development; alternatively, a graduate degree with two to four years of prior related experience.
  • Demonstrated hands-on experience with electro-mechanical assembly design, including mechanisms, motors, gear-trains, mounts, and flexures for harsh or precision environments.
  • Experience with electronics packaging design, including thermal, structural, and environmental considerations.
  • Experience with sensor packaging and integration, including interface coordination across mechanical, electrical, and optical disciplines.
  • Proficiency in CAD tools such as Siemens NX, including part modeling, assembly design, drawing creation, and Teamcenter PLM workflows.
  • Experience performing structural, thermal, vibration, or fluid flow analyses using FEA and CFD tools such as Ansys, FEMAP, or SolidWorks Simulation.
  • Ability to work independently on hardware development tasks across the full engineering lifecycle, from concept through production.
  • Experience with prototype fabrication, hardware bring-up, assembly procedures, and manufacturing support.
  • Proficiency in common engineering and business tools such as Excel, Word, and PowerPoint.
  • A bachelor's degree and a minimum of four years of prior relevant experience, or a graduate degree and a minimum of two years of prior related experience. In lieu of a degree, a minimum of eight years of prior related experience.
  • Ability to engage effectively across engineering disciplines, with strong organizational and problem-solving skills.

Responsibilities

  • Lead and execute the design and integration of electro-mechanical assemblies, including gear-trains, motors, adjustable mounts, flexures, and precision mechanisms for operational environments involving temperature extremes, shock, vibration, and contamination.
  • Develop electronics packaging designs accounting for thermal management, shock and vibration, EMI/EMC constraints, signal integrity, manufacturability, and long-term reliability.
  • Lead sensor packaging and integration, including physical layout, interface definition, keep-in/keep-out volume management, connector and harness routing, and coordination with electrical, optical, and systems engineering teams.
  • Design and integrate optical systems packaging, including opto-mechanical mounts, lens assemblies, detector housings, alignment features, and precision positioning hardware for electro-optical systems.
  • Develop electro-optical mechanism designs, including gimballed systems, scanning mechanisms, focus assemblies, and precision positioning hardware, meeting performance, alignment, and environmental requirements.
  • Perform and interpret structural, modal, thermal, and fluid flow analyses using FEA and CFD tools to validate designs, resolve technical issues, and support hardware decisions.
  • Create and maintain CAD models, assemblies, and fabrication drawings in accordance with engineering standards, GD&T practices, and program-specific requirements.
  • Drive prototype fabrication, hardware bring-up, assembly procedures, and manufacturing build support with increasing ownership and accountability.
  • Design and develop test equipment, validation fixtures, and production support tooling.
  • Lead or support hardware testing, data collection and analysis, failure analysis, and root cause investigations, and implement corrective actions.
  • Partner with electrical, optical, systems, software, and manufacturing engineers to manage packaging constraints, interface definitions, and total system integration.
  • Contribute to design reviews, cost and schedule estimation, risk identification, and technical documentation.
  • Provide technical guidance and mentorship to junior engineers.
  • Apply and champion AI-enabled workflow improvements while adhering to responsible and ethical AI practices.

Desired Qualifications

  • Experience with optical systems packaging, opto-mechanical design, or electro-optical mechanism design, including gimballed or scanning systems.
  • Familiarity with electronics packaging for harsh environments, including thermal gradient control, vibration isolation, and environmental sealing strategies.
  • Experience with motion control systems, including motors, gear-trains, encoders, and precision positioning mechanisms, including application-level integration and troubleshooting.
  • Experience with test equipment design and fabrication, hardware verification, and production test support.
  • Demonstrated experience with tolerance analysis, GD&T, interface definition, and engineering drawing interpretation and creation.
  • Familiarity with manufacturing operations, assembly processes, DFMA principles, and production flow.
  • Experience with PLM systems such as Siemens Teamcenter or similar engineering data management platforms.
  • Proficiency in scripting or programming tools such as Python, MATLAB, or VBA for engineering analysis, data reduction, or workflow automation.
  • Experience in robotics, consumer electronics, aerospace, defense, electro-mechanics, opto-mechanics, or high-reliability hardware development.
  • Exposure to cost and schedule estimation, project planning, and participation in formal design reviews.
  • Experience providing technical guidance or informal mentorship to junior engineers or technicians.
  • Familiarity with SAP or similar enterprise resource planning and engineering database systems.
  • Demonstrated use of AI tools to improve engineering workflows, efficiency, and quality.
  • Ongoing AI skill development and experience implementing responsible, ethical AI practices.
  • An active Secret or Top Secret US DoD clearance or the ability to obtain a US DoD clearance.
