• Testing, debugging, and troubleshooting these systems
• Working alongside other developers, hardware engineers, and mechanical engineers on integration of the systems into the product
• Maintaining, supporting, and improving systems after initial delivery

Qualifications

• Experience developing low-level software (basic software, drivers, bootloaders) for embedded systems
• Extensive knowledge of C and Python
• Familiarity with integrating code from multiple sources (e.g. Simulink generated code) into a single project
• Experience with low-level microcontroller development (STM32, ESP32), RTOS (FreeRTOS), and hardware abstraction layer usage
• Experience with peripherals and communication protocols such as SPI, CAN, I2C, RS-485, and Ethernet
• Experience with hands-on testing and debugging code on a bench setup using oscilloscopes, logic analyzers, JTAG probes, etc.
• Familiarity with reading datasheets, schematics, and other technical documentation
• Experience managing source code with Git and GitLab
• Strong documentation and communication skills
• Experience providing post-production technical support
