About The Position

We are seeking an experienced Embedded Firmware Engineer Contractor to develop firmware for a high-performance multichannel thermal control system based on an STM32H7 microcontroller. The controller performs fast simultaneous temperature acquisition, executes multiple independent PID control loops, and communicates system data through a 100 Mbps Ethernet interface. The ideal candidate is a hands-on engineer who is equally comfortable developing embedded firmware and troubleshooting hardware in the laboratory.

Requirements

• BS degree in electrical engineering, computer engineering or closely related field and 7+ years of embedded firmware development experience OR MS degree in electrical engineering, computer engineering, or closely related field and 4+ years of embedded firmware development experience.
• Experience developing and tuning temperature control systems, power control systems, or other real-time feedback control applications.
• Strong C programming skills.
• Extensive experience with development on STM32H7 devices.
• Experience implementing PID or other closed-loop control algorithms.
• Experience with hardware bring-up, prototype validation, and schematic review.
• Proficiency using oscilloscopes, logic analyzers, and digital multimeters to troubleshoot firmware and hardware integration issues.

Responsibilities

• Develop bare-metal firmware for an STM32H7-based thermal control platform.
• Implement simultaneous temperature acquisition from I2C and RTDs
• Develop, implement, and tune multiple independent PID-based control loops.
• Support hardware bring-up, integration, and validation activities.
• Debug peripherals and interfaces like ADCs, I2C, PWM, Ethernet, and GPIOs.
• Work closely with hardware engineers to diagnose and resolve board-level and system-level issues.
• Participate in system testing, performance characterization, and firmware optimization.
