Contract Senior Unity Developer Jobs (NOW HIRING)

We are not accepting submissions from third-party staffing vendors and cannot consider C2C arrangements.

Our client is an innovative technology company developing advanced portable and wearable monitoring systems. Its multidisciplinary engineering and scientific teams work together to create compact, battery-powered products that combine embedded electronics, sensing technologies, and data-driven capabilities.

We are seeking a hands-on Senior Electrical Engineer to support the development and refinement of embedded hardware across a growing product portfolio. This contract position will focus heavily on new PCB bring-up, laboratory troubleshooting, circuit development, and hardware integration for compact, battery-operated devices.

The ideal candidate has successfully taken multiple embedded products from initial board power-up through functional hardware. This individual should be comfortable diagnosing complex issues involving power, analog, digital, and mixed-signal circuitry and collaborating closely with firmware, mechanical, software, and scientific team members.

• Perform first-power-on activities and bring up newly developed prototype PCBs.
• Diagnose and resolve electrical issues in battery-powered embedded systems.
• Use laboratory equipment to isolate faults across power, analog, digital, and mixed-signal circuits.
• Develop new circuits and electronic subsystems from initial concept through functional hardware.
• Evaluate development kits and create breakout or test boards to validate new components before full product integration.
• Review and update schematics, component selections, and PCB layouts.
• Support the design and integration of miniaturized electronics for portable and wearable products.
• Work with firmware and software engineers to troubleshoot hardware and embedded software interactions.
• Measure, characterize, and improve power consumption and battery performance.
• Contribute to battery-management and low-power design decisions.
• Coordinate technical activities with PCB fabrication partners and contract manufacturers.
• Document test results, design changes, technical findings, and recommended solutions.
• Clearly communicate progress, risks, and unresolved issues to the engineering team.
• Report to the manager responsible for electrical engineering research and development.

• Bachelor’s degree in Electrical Engineering or a related technical field.
• At least five years of hands-on electrical engineering experience.
• Significant experience developing battery-powered embedded, portable, or wearable systems.
• Demonstrated success bringing new PCB designs from initial power-on through a fully functioning system.
• Strong laboratory debugging and root-cause analysis skills.
• Experience designing and integrating compact or miniaturized electronics.
• Practical knowledge of mixed-signal circuit design.
• Proficiency with Altium Designer for schematic capture and PCB development.
• Ability to interpret technical data, document findings, and communicate solutions clearly.
• Strong collaboration skills and experience working within cross-functional product-development teams.

• Experience designing original circuits and subsystems from concept through working hardware.
• Experience assessing development kits and creating test or breakout boards for new integrated circuits.
• Ability to read and modify embedded C code when troubleshooting hardware and firmware integration.
• Experience with rigid, flex, and rigid-flex PCB designs.
• Familiarity with Bluetooth Low Energy microcontrollers, including the Nordic nRF family or similar platforms.
• Knowledge of battery-management systems, charging circuitry, and low-power design techniques.
• Experience working directly with PCB fabricators and electronics contract manufacturers.
• Background developing electronics for wearable, medical, sensing, or other highly compact products.

• Location: Morrisville, NC—on-site
• Schedule: Contract engagement
• Compensation: Engagement rate will be based on the selected candidate’s experience and qualifications
• Engagement type: Direct applicants only; no third-party vendors or C2C arrangements
