About the Role

We’re looking for a versatile Embedded Systems Engineer to lead the electrical and firmware development of a next-generation air management system — from concept through production in Nashville, TN. In this role, you’ll design and implement the embedded hardware and firmware that control key product functions, ensuring reliability, manufacturability, and long-term supportability. You’ll be responsible for creating schematics, PCB layouts, and embedded control firmware, while also supporting system integration, validation, and manufacturing readiness. A significant part of your work will involve collaborating with cross-functional teams to bring up new hardware, validate firmware developed by other engineers, and ensure seamless communication between electrical, mechanical, and software subsystems. This role blends hands-on design, embedded programming, and practical problem-solving, making it ideal for an engineer who enjoys working from the bench to the production floor and seeing their designs come to life.

What You’ll Do

• · Design and develop electrical schematics and PCB layouts for embedded control systems, selecting components and ensuring manufacturability.
• · Validate and test firmware from motor controller OEMs.
• · Architect and implement embedded firmware for microcontrollers (e.g., STM32, ESP32, or similar), handling I/O, sensors, and communications.
• · Design and document wire harnesses, specifying wire gauge, connector types, and routing for robustness and EMI mitigation.
• · Develop and debug low-level firmware in C/C++ for control loops, timing-critical tasks, and interface drivers.
• · Implement and tune communication protocols such as I²C, SPI, UART, CAN, and RS-485.
• · Integrate and manage user interface components including buttons, LEDs, potentiometers, and displays.
• · Support system bring-up and validation, performing hardware-in-the-loop testing and troubleshooting at both board and system levels.
• · Collaborate with mechanical engineers to ensure PCBs and harnesses align with mechanical constraints and assembly requirements.
• · Work with suppliers and contract manufacturers to validate part selection, optimize DFM/DFT, and support production readiness.
• · Generate and maintain comprehensive design documentation: schematics, firmware source, BOMs, harness drawings, and test procedures.

Basic Qualifications

• · Bachelor’s degree in Electrical Engineering or a related field.
• · 5+ years of experience in electrical engineering roles, with experience in embedded
• · Proficiency in electrical CAD tools (e.g., Altium Designer, Eagle, or similar).
• · Experience working with embedded systems and microcontrollers.
• · Experience designing PCBs with user interface elements such as LEDs, buttons, and potentiometers.
• · Strong understanding of wire harness design, including electrical and mechanical considerations.
• · Hands-on experience working with manufacturers to source components and implement DFM (Design for Manufacturability).
• · Knowledge of EMI/EMC design considerations and best practices.
• · Ability to work independently and collaboratively in a fast-paced environment.
• · Excellent problem-solving skills and attention to detail.

Bonus Qualifications

• · Experience designing products for outdoor or rugged environments.
• · Familiarity with battery-powered systems and low-power design techniques.
• · Experience with regulatory compliance (e.g., UL, CE, FCC).
• · Strong project management skills and experience leading electrical design projects.
• · Experience with mechanical CAD tools and rapid prototyping.
