Onsite Embedded Firmware Engineer — Full Lifecycle

Pentangle Tech Services | P5 Group; Saint Paul (MN); In loco; USD 100.000 - 140.000; Tempo pieno

Descrizione del lavoro

Pentangle Tech Services | P5 Group in Eagan, MN, is seeking an Embedded Firmware Software Engineer to design, develop, and validate embedded firmware for new sensor products used in laundry systems.

You will own the full firmware lifecycle from concept to deployment, work closely with hardware engineers, and implement connectivity protocols like Modbus, CANBus, and BLE, using FreeRTOS. The role emphasizes independence and high autonomy in a small team.

Competenze

• 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.

Mansioni

• 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 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.
