This is a full-time, on-site role for a Senior Electrical Engineer based in Coppell, TX. This role is hands-on and spans the full product lifecycle, from concept through production.

The Sr Electrical Engineer will design, develop, and validate embedded hardware systems, including mixed-signal circuits, power architectures, and sensor interfaces. Responsibilities include schematic capture, PCB design oversight, firmware-hardware integration, and system-level debugging.

The role works closely with firmware, mechanical, manufacturing, and test engineering teams to deliver robust, production-ready designs. Additional responsibilities include troubleshooting field issues, driving design improvements, and supporting new product introductions (NPI).

• Strong background in electrical engineering with hands-on design experience in embedded systems
• Experience with analog and digital circuit design, including sensor signal conditioning and power management
• Proven ability to analyze, debug, and resolve complex hardware issues from prototype through production

Wireless / BLE Experience

• Practical experience designing and integrating Bluetooth Low Energy (BLE) or similar wireless systems
• Understanding of advertising, scan response, GATT services, and low-power communication strategies
• Experience optimizing wireless performance for battery-powered devices, including duty cycling, power budgets, and RF considerations
• Familiarity with BLE security concepts such as pairing, encryption, and firmware update (FOTA) mechanisms

PCB Design Experience

• Hands-on experience with schematic capture and multi-layer PCB design
• Strong understanding of layout best practices, including signal integrity, grounding, impedance control, and EMI/EMC considerations
• Experience reviewing layouts for manufacturability (DFM) and assembly (DFA), including collaboration with PCB vendors
• Ability to debug hardware issues using lab equipment (oscilloscope, logic analyzer, spectrum analyzer, etc.)
• Experience with power distribution and embedded power systems
• Strong problem-solving skills with the ability to work across hardware and firmware boundaries
• Excellent communication skills and ability to collaborate across cross-functional teams
• Bachelor’s degree in Electrical Engineering or related field
