Title : Embedded Firmware Software Engineer
Location : Eagan, MN
Duration : 6 Months
Rate : Open
Relevant Experience: 5 Years
Top Skills:
- C/C pure embedded environment
- Firmware Free RTOS ModBus Sensors
- Custom board bring up - stand up diagnose firmware from the ground up BLE-Bluetooth
Job Description
This role focuses on developing embedded firmware and software for new sensor products used in laundry systems that monitor water and energy usage. You will work 100% onsite in Eagan, MN, collaborating closely with hardware and electrical engineers to design, build, and validate custom embedded solutions from the ground up. The position offers high autonomy, exposure to advanced technologies, and the opportunity to own the full firmware development lifecycle for net-new products rather than sustaining legacy systems.
Responsibilities
- Design, develop, and maintain embedded firmware in C and C for microcontroller-based systems used in laundry applications.
- Own the end-to-end firmware development lifecycle from concept and architecture through build, test, debug, and deployment.
- Develop and implement connectivity between sensors and systems to monitor heat and temperature, water usage, and energy usage cycles.
- Work extensively with communication protocols such as Modbus and CANBus, and support Bluetooth Low Energy (BLE) connectivity where applicable.
- Collaborate closely with hardware and electrical engineers to perform custom board bring-up on new hardware platforms.
- Diagnose, troubleshoot, and resolve firmware issues at the board and system level, including low-level device drivers and RTOS-related problems.
- Build embedded systems from scratch, including setting up FreeRTOS (or similar RTOS) environments and integrating sensors and communication stacks.
- Participate in the design and implementation of communication-focused sensor solutions that measure differential pressure and other key parameters.
- Contribute to the development of automated checks to detect when filters and related components require maintenance or replacement.
- Use Agile development practices and tools such as JIRA and DevOps-based testing workflows to plan, track, and validate work.
- Collaborate cross-functionally with a small team of firmware, software, and hardware engineers while maintaining a high level of independence.
- Take ownership of assigned deliverables, ensuring high quality, reliability, and performance of the embedded firmware.
- Support testing and debugging activities in a lab environment, including working with sensors, boards, and related hardware.
- Document firmware designs, interfaces, and testing procedures to support ongoing development and future enhancements.
Essential Skills
- Proven experience in embedded firmware development for microcontroller-based systems.
- Strong proficiency in C and C programming in a pure embedded environment.
- Hands-on experience with RTOS platforms such as FreeRTOS or similar real-time operating systems.
- Demonstrated ability to perform custom board bring-up, including initializing hardware and validating low-level functionality.
- Strong debugging and troubleshooting skills at the firmware and hardware interface level.
- Experience working with communication protocols such as Modbus and CANBus for sensor and system connectivity.
- Background in developing communication-focused sensor solutions, including integration and data handling.
- Ability to work independently and in a small team, taking ownership of deliverables and collaborating cross-functionally.
- 5 15 years of experience working with sensors and communication protocols in embedded systems.
- Comfort working in a fast-paced environment and partnering closely with hardware engineers on new product development.
Additional Skills & Qualifications
- Experience with Bluetooth or Bluetooth Low Energy (BLE) for wireless communication.
- Familiarity with Agile development workflows and tools such as JIRA and DevOps-based testing frameworks.
- Experience with sensor-related development, including integration, calibration, and data processing.
- Exposure to Simulink, Python, or other tools used in embedded system modeling, testing, or automation.
- Background in developing firmware for measuring differential pressure, water flow, or similar sensor applications.
- Experience working with device drivers, low-level hardware interfaces, and firmware diagnostics.
- Prior involvement in full lifecycle ownership of embedded products, from initial concept through deployment and support.
- Interest in high-technology environments and net-new product development for connected systems.
