Job Schedule: 9/80: Employees work 9 out of every 14 days – totaling 80 hours worked, and have every other Friday off

Job Description:

We are seeking a motivated and detail-oriented Electro-Mechanical Engineer to support the design, integration, testing, and production of complex electro-mechanical systems involving electronics packaging, sensor integration, optical systems packaging, and electro-optical mechanism design. This is an excellent opportunity for an early-career engineer to develop broad technical skills across mechanical, electrical, and optical disciplines while contributing to high-reliability hardware in a fast-paced, collaborative engineering environment.

The ideal candidate will work alongside experienced engineers across mechanical, electrical, optical, software, firmware, systems engineering and manufacturing teams to deliver tightly integrated solutions for advanced products and systems. Responsibilities include electro-mechanical design and analysis, electronics and sensor packaging, opto-mechanical systems packaging, electro-optical mechanism design, CAD modeling, tolerance analysis, thermal and structural analysis, hardware bring-up support, test fixture development, and design-for-manufacture-and-assembly (DFMA).

Key Responsibilities

Support the design and integration of electro-mechanical assemblies, including gear-trains, motors, adjustable mounts, flexures, and precision mechanisms for demanding environments
Contribute to electronics packaging designs that account for thermal management, shock and vibration, EMI/EMC constraints, manufacturability, and reliability
Support sensor packaging and integration efforts, including physical layout, interface definition, keep-in/keep-out volume management, and interface coordination with electrical and optical teams
Assist in the design and integration of optical systems packaging, including opto-mechanical mounts, lens assemblies, detector housings, and alignment features for electro-optical systems
Develop and support electro-optical mechanism designs, including gimballed systems, scanning mechanisms, focus assemblies, and precision positioning hardware
Perform structural, modal, thermal, and fluid flow analyses using FEA and CFD tools to validate designs and support hardware decisions
