Embedded Microcontroller Engineer Jobs in Wisconsin

Job Title: Experienced Embedded Software Engineer

Job Description

This role focuses on designing and delivering robust, efficient, and scalable embedded software for microcontroller-based control systems used in residential and power products. The Embedded Software Engineer works closely with hardware, software, and product teams to develop embedded solutions running on real-time and embedded operating systems, contributing throughout the full development lifecycle from architecture and implementation to testing and sustaining engineering. This position combines hands-on embedded development, technical leadership, and mentorship within a cloud-connected IoT environment.

Responsibilities

• Design, develop, and maintain embedded software for microcontroller-based systems using C and C++ on platforms such as QNX, RTX, ZephyrOS, and similar operating systems.
• Collaborate with cross-functional teams, including hardware, software, and product stakeholders, to define software requirements and system architecture.
• Own and develop elements of embedded software using layered architectures and embedded operating systems, ensuring scalability and maintainability.
• Plan and oversee unit testing, integration testing, regression testing, and system validation to ensure software reliability, performance, and testability.
• Develop networking implementations and application code for wireless processors supporting Wi-Fi, Bluetooth, and ISM bands within embedded systems.
• Implement and support industry-standard communication protocols such as RS-485 (Modbus), SAE J1939 CAN, Ethernet, and USB within embedded applications.
• Conduct code reviews, follow release processes, and contribute to continuous improvement of development workflows and engineering practices.
• Support hardware troubleshooting and board bring-up during product development and testing, working closely with hardware and circuit design teams.
• Document software design, architecture, interfaces, and implementation details to ensure clarity, traceability, and ease of maintenance.
• Use industry-standard software diagnostic tools, including emulators, debuggers, and oscilloscopes, to debug and verify controller software at the unit level.
• Develop custom diagnostic software when needed to validate specialized features or functions in embedded controllers.
• Technically lead the breakdown of software scopes of work, and help develop project timelines and budgets for embedded software deliverables.
• Mentor less experienced team members in core embedded software development practices, coding standards, and debugging techniques.
• Participate in and support release processes, including walking through workflow and process steps to ensure high-quality software delivery.
• Contribute to both sustaining engineering activities and new product development initiatives within an IoT and cloud-connected environment.

Essential Skills

• Bachelor of Science degree in Electrical and Computer Engineering or Computer Engineering required.
• 6+ years of work experience in embedded software development.
• Strong embedded systems knowledge and experience working closely with hardware and circuits in a co-design environment.
• Experience developing embedded software using layered architectures and embedded operating systems, including RTOS platforms.
• Proficiency in C and C++ programming languages, including syntax, generally accepted code structure, and object-oriented programming.
• Hands-on experience with industry-standard communication protocols such as RS-485 (Modbus), SAE J1939 CAN, Ethernet, and USB.
• Experience designing software for test, including unit testing, regression testing, board bring-up, and end-of-line production testing.
• Experience with embedded C and C++ for microcontroller-based systems, including CAN-based communication.
• Ability to design, implement, and maintain embedded software for QNX, RTX, ZephyrOS, or similar operating systems.
• Familiarity with release processes, code reviews, and structured development workflows.

Additional Skills & Qualifications

• Master’s degree in Electrical and Computer Engineering, Computer Engineering, or a related field is preferred.
• Familiarity with CAN analysis tools such as Vector CANalyzer, CANape, and CANoe.
• Familiarity with debuggers and emulators for ARM-based processors.
• Familiarity with wireless certification requirements for Wi-Fi, Bluetooth, and ISM bands, and experience navigating the certification process.
• Experience with wireless and networking features in embedded systems is a plus.
• Familiarity with MATLAB/Simulink model-based code development and integration.
• Experience working with cloud-connected and IoT systems.
• Strong communication skills with the ability to convey complex technical concepts to diverse audiences.
• High level of motivation with the ability to collaborate effectively in a team environment and work independently to achieve results.
• Preference for candidates with primary programming experience in C, with C++ as an additional strength.
