Lead firmware development and ownership for legacy and new electromechanical products. Develop bare-metal C/C++ firmware for STM32H7 microcontrollers, bring up boards, build peripheral drivers, debug hardware, and maintain a Windows-based C++ GUI. Support Ethernet, CAN, serial, and scripting interfaces; document requirements, architectures, protocols, testing, and releases. Provide customer and sales support, train users, manage Git traceability, and prioritize work independently across multiple projects.
Main Objectives
- Lead the development and support of all firmware in the Electrical Engineering group, becoming the group's firmware owner within approximately six months.
- Act as the technical bridge between sales, customers, and engineering: provide pre and post sales support, and train customers to interface with our equipment.
- Implement firmware changes on legacy products still in production, including analysis of older designs where documentation is limited.
- Support the development of new electronic boards, from pin definition through firmware delivery.
Essential Functions/Major Responsibilities:
- Develop bare metal C/C++ firmware for STM32H7 microcontrollers, from pin assignment and board bring up with hardware engineers through peripheral drivers and debugging (JTAG, oscilloscopes, logic analyzers, etc.)
- Develop and improve our advanced PC based C++ graphical user interface, which supports multiple communication interfaces (Ethernet, CAN, serial), command and scripting operation, and real time graphing.
- Create and maintain documentation: initial design requirements, firmware architecture and design documents, interface specifications (command sets and protocols), test plans and results, release notes, and customer interface guides.
- Write clean, well structured, well commented code, managed in Git with full traceability of changes to requirements and releases.
Essential Quality Expectations
- Strong analytical skills and sound engineering judgment under ambiguity.
- Ability to quickly learn and take ownership of existing code bases, including those with limited documentation.
- Self directed, able to work as the group's sole firmware engineer and set priorities across multiple projects.
- Clear communication with customers and internal teams, including teaching customer engineers to use our interfaces.
- Commitment to technical excellence, documentation, and knowledge transfer.
- Customer oriented thinking and ability to represent the company in technical discussions
Qualifications & Requirements:
- Education/Training: Bachelor's degree in electrical engineering, computer engineering, or a related field (MS desired).
- Experience: Minimum of 8 years of experience in firmware development and application support for complex electromechanical systems / control systems.
- Skills/Technical Requirements:
- Strong proficiency in C and C++, including Windows application development.
- Experience with bare metal firmware on STM32 or similar ARM Cortex M microcontrollers, understanding of microcontroller architecture and digital circuit design, experience bringing up boards from schematics
- Experience with communication protocols such as UART, SPI, I2C, CAN, and Ethernet. EtherCAT is a plus.
- Experience in bootloader development and Git.
- FPGA experience is a plus.
- Experience with motion control and/or control systems. Thermal systems experience is a plus.
- Willingness to travel as required for projects and customer support.
- Excellent English communication skills. German and/or French is a plus.
