Senior Mechanical Engineer

POSITION

Senior Inspector - Incoming Quality Control (IQC)

REPORTING TO

Senior Director, Platform Engineering

LOCATION

Westborough

GENERAL FUNCTION

The Senior Mechanical Engineer is responsible for the design, development, analysis, and production support of mechanical and electromechanical assemblies used in Kopin's microdisplay-based products. This includes compact display modules, optical engine assemblies, head-mounted displays, weapon sights, medical viewers, FPV goggles, and other ruggedized near-eye display systems. This role requires strong mechanical design capability, hands-on product development experience, and the ability to work across optical, electrical, embedded software, manufacturing, and systems engineering disciplines. The Senior Mechanical Engineer leads mechanical design activities from concept through prototype, qualification, and production transition, ensuring that designs meet performance, SWaP, manufacturability, reliability, and cost requirements. The Senior Mechanical Engineer is expected to operate with substantial independence, provide technical guidance to junior engineers, and contribute to system-level trade studies involving packaging, thermal performance, structural integrity, ergonomics, environmental robustness, and manufacturability.

JOB DUTIES AND RESPONSIBILITIES

Lead the mechanical design and development of microdisplay-based products and assemblies from concept through production release. Design compact mechanical and electromechanical assemblies for optical engines, display modules, HMDs, weapon sights, medical viewers, and related embedded display systems. Develop 3D CAD models, detailed 2D drawings, tolerance stack-ups, and production documentation in accordance with company standards. Apply GD&T, tolerance analysis, material selection, and DFM/DFA principles to ensure robust, manufacturable, and cost-effective designs. Perform mechanical analysis including structural, thermal, vibration, shock, and tolerance analysis to validate product performance and guide design decisions. Support opto-mechanical design activities involving precision alignment, optical mounting, display positioning, thermal control, sealing, and mechanical stability. Develop mechanical concepts that balance SWaP, ergonomics, environmental requirements, manufacturability, serviceability, and cost. Design and support mechanical fixtures, tooling, alignment aids, and test equipment used for prototype builds, production, verification, and qualification testing. Support prototype builds, design verification, environmental testing, and root-cause analysis of mechanical and system-level issues. Work closely with electrical, optical, systems, manufacturing, and quality engineering teams to support product development. Support design reviews, risk assessments, FMEAs, and corrective action activities. Create and maintain engineering documentation including drawings, BoMs, ECOs, design reports, test plans, and verification records. Interface with suppliers, machine shops, contract manufacturers, and external design partners to support fabrication, assembly, and production transition. Support manufacturing and production teams with technical guidance, process improvements, fixture development, yield improvement, and troubleshooting. Mentor junior mechanical engineers and provide technical guidance on design methods, documentation, analysis, and product development best practices.
