Job description

Location: LaVergne, TN (southeast of Nashville)

Job Type: Full-Time, onsite

At Coats, we design, build, and support the technologies and machines that keep automotive shops running. Our portfolio includes tire changers, wheel balancers, aligners, lifts, inspection systems, and compressed air solutions, all engineered for safety, durability, and real-world productivity.

The Role

We’re hiring a mid-level Software Engineer to develop the embedded software that runs our automotive service equipment. This is hands-on work: your code will control motors, read sensors, and communicate with hardware on machines you can walk up to and test. You’ll work closely with our hardware, electrical, and manufacturing teams across the full development lifecycle, from requirements and design through coding, testing, debugging, and field support. This is not a web or cloud-only role. We’re looking for engineers who have shipped software that runs on, and talks to, physical machines.

Key Responsibilities

• Design, develop, debug, and test embedded firmware and software for automotive service machines such as tire changers and wheel balancers
• Interface software with machine hardware, including sensors, actuators, motor controllers, and other control systems
• Test and troubleshoot directly on machines, on the shop floor and in the lab
• Collaborate with electrical, hardware, and manufacturing engineers to define requirements and resolve system-level issues
• Participate in code reviews, test planning, and deployment of new features
• Ensure software meets performance, reliability, and safety standards

Required Qualifications

• Bachelor’s degree in Electrical Engineering or Computer Engineering from an accredited university
• 2-6 years of professional experience developing embedded software for machines, instruments, or other hardware-based systems
• Hands-on experience interfacing software with hardware, such as sensors, motor control, or communication protocols (e.g., serial, CAN, SPI, I²C, Modbus, USB)
• Proficiency in C# / .NET and Visual Studio
• Strong object-oriented programming and software design skills
• Experience with Git and bug-tracking tools (Atlassian/Jira a plus)
• Ability to work independently and own features through the full software lifecycle
• Comfort with hands-on debugging using lab tools (oscilloscope, logic analyzer, multimeter, etc.)

Preferred Qualifications

• C / C++ proficiency
• Linux or Android experience
• Experience in a manufacturing or industrial equipment environment
• .NET MAUI / Xamarin Forms and MVVM
• Customer-facing UI/UX experience for machine interfaces
• Azure or AWS experience for connected-equipment features

Work Authorization

Candidates must be legally authorized to work in the United States without the need for current or future employer-sponsored work authorization. We are unable to provide visa sponsorship for this role.

Note to Recruiters and Staffing Firms

This is a direct-hire position, filled in-house by The Coats Company. We are not working with recruiters, staffing agencies, or third-party firms on this role. Resumes or talent submitted by third parties will be treated as direct applications, and no fees will be owed.
