Electrical Engineer III Hardware

GENERAL FUNCTION:

The Electrical Engineer III with a focus in hardware design is responsible for designing, implementing, and validating custom electronics used in Kopin's microdisplay-based systems. This includes driver boards, interface modules, imaging subsystem electronics, and system-level hardware for weapon sights, HMDs, medical viewers, FPV goggles, and related embedded platforms.

The Electrical Engineer III performs PCB-level design with substantial independence, executes detailed hardware analysis, and participates in cross-functional integration with systems, firmware, optics, and mechanical engineering. This role requires strong experience with embedded hardware development, power systems, high-speed digital interfaces, and SWaP-optimized electronics.

JOB DUTIES AND RESPONSIBILITIES:

• Architect and design custom PCB assemblies for:
• Microdisplay driver and timing boards
• Sensor/IMU and camera interface boards
• Control and communication modules for integration into weapon, aircraft, or host systems
• Perform schematic capture and component selection (FPGAs, MCUs, power ICs, regulators, ADC/DACs, serializers/deserializers, level translators) with consideration for SWaP, cost, and component availability.
• Design robust power distribution networks for portable and vehicle-powered electronics, including DC-DC converters, sequencing, protection circuitry, and efficiency optimization.
• Implement and validate high-speed and mixed-signal interfaces including LVDS, MIPI, HDMI/DP, SPI/I²C, UART, USB, GPIO, and embedded sensor interfaces.
• Define and document electrical interfaces to optics, mechanics, and firmware teams, including pinouts, timing requirements, EMI/ESD concerns, connector/harness guidelines, and interface constraints.
• Support or execute PCB layout in Altium, including stack-up development, controlled-impedance routing, placement for thermal behavior, and manufacturability considerations.
• Execute board bring-up and debug:
• Power-on sequencing, functional validation, and test-point evaluation
• Signal integrity, timing closure, and digital interface reliability
• Integration with firmware, FPGA logic, optics modules, and sensors
• Conduct environmental and thermal stress testing where applicable
• Build, iterate, and characterize lab prototypes and test fixtures for concept evaluation and verification.
• Generate and maintain engineering documentation such as schematics, BoMs, design reports, ECOs, test procedures, and revision-controlled hardware artifacts.
• Work closely with Systems, Embedded Software, Optics, and Mechanical Engineering to ensure system-level functionality, performance margins, and requirement compliance.
• Participate in DFM/DFT reviews and support NPI activities with manufacturing partners and contract assemblers.

MINIMUM JOB REQUIREMENTS:

Kopin is a defense contractor and is subject to International Traffic in Arms Regulations (ITAR). You must be a US Citizen or Permanent Resident (green card holder) to be considered for this position.

• Bachelor's degree in Electrical Engineering or related field.
• 5–8 years of experience in PCB-level hardware development for embedded systems.
• Proficiency with Altium Designer or comparable schematic/layout tools.
• Demonstrated experience with:
• Power supply design (buck/boost, PMICs, protections)
• High-speed digital interfaces and mixed-signal board design
• FPGA/MCU-based board implementation and bring-up
• Strong hands-on lab experience (oscilloscopes, logic analyzers, power analyzers, JTAG, rework).
• Ability to execute designs independently from concept through prototype validation.
• Strong written and verbal communication skills and ability to participate in technical design reviews

PREFERRED JOB REQUIREMENTS:

• Experience with near-eye displays, AR/VR devices, imaging sensors, or HUD/HMD electronics.
• Experience with:
• FPGA-centric designs (high-speed data paths, display pipelines)
• SI/PI tools and SPICE or behavioral modeling
• EMC/EMI compliance and rugged-environment hardware design
• Flex circuit design experience, including rigid-flex stack-ups, impedance control, bend-radius constraints, and miniature connector selection.
• Basic embedded engineering familiarity, including MCU/SoC architectures, firmware integration considerations, and power/control sequencing.
• Working knowledge of embedded communication protocols, including:
• SPI, I²C, UART
• LVDS and MIPI-DSI/CSI
• HDMI/DisplayPort
• USB, GPIO, and peripheral buses
• Experience in small-to-mid-size R&D environments involving both design and hands-on prototyping.
• Familiarity with IPC standards and basic MIL-STD environmental requirements.

PHYSICAL REQUIREMENTS:

• Able to rotate from sitting to standing, lift up to 20 pounds, and gown according to clean room protocol
