Qualifications

• Associate degree in Electronics Technology or equivalent military/technical training
• 3+ years hands-on electronics assembly, integration, and testing experience
• Experience with PCB design tools (KiCad preferred) and basic circuit simulation (SPICE)
• Skilled in soldering, wiring, and crimping to industry standards
• Familiarity with Arduino IDE or similar environments for prototyping
• Ability to read/interpret electrical schematics and component datasheets
• Proficiency with test instruments (multimeter, oscilloscope, logic analyzer)
• Ability to work independently, problem-solve, and deliver results with limited supervision

Responsibilities

• Identify, research, and evaluate electronic components using vendor catalogs (e.g., Digi-Key, Mouser)
• Read datasheets to confirm specifications, pinouts, and integration requirements
• Maintain part libraries and BOMs, proposing alternatives when supply constraints occur
• Assist with schematic capture and PCB layout using KiCad and SPICE-based tools
• Prepare fabrication and assembly files for outside PCB manufacturing services, ensuring compliance with engineering standards
• Coordinate orders for bare boards and/or assembled PCBs through contract manufacturers, monitoring quality and delivery timelines
• Assemble, solder, and rework prototype PCBs and subsystems
• Perform unit tests, quality control, and performance benchmarking of custom electronics
• Troubleshoot independently using multimeters, oscilloscopes, and logic analyzers, escalating only when needed
• Wire and integrate PCBs, sensors, and RF modules into SensXR subsystems
• Address ruggedization, EMI/EMC considerations, and field reliability requirements
• Support firmware bring-up and perform basic coding/debugging in Arduino IDE
• Build and adapt prototypes, cable assemblies, and enclosures
• Support lab and field tests of SensXR hardware, capturing logs and diagnostic data
• Provide structured feedback for iterative design improvements and system reliability
• Maintain accurate build/test documentation aligned with ISO 9001 processes
• Contribute to design reviews, documenting revisions and part traceability
• Ensure all assemblies meet workmanship standards (IPC/WHMA-A-620 preferred)
• Experience with PCB designs from schematic through fabrication and validation
• Background with sensor integration (gas, RF, GPS, IMU, etc.)
• Exposure to ruggedized/military electronics or wearable/AR-integrated systems
• IPC/WHMA-A-620, IPC-A-610 certifications
• Creative, R&D-oriented problem solver
