What Impact You Will Have

We are seeking a highly skilled Embedded Systems Engineer to play a critical role in the development of our advanced cooling system. The ideal candidate will have a strong background in STM32 microcontrollers firmware and expertise in designing and implementing embedded solutions for complex control systems. Your work will directly impact the efficiency and reliability of our cutting-edge cooling technology.

What You’ll Do

Firmware Development:

• Design, develop, and maintain embedded firmware for our cooling system using STM32 microcontrollers.
• Implement control algorithms for managing the cooling process, including temperature regulation, fan control, and fluid management.
• Develop and integrate communication protocols for interaction with sensors, actuators, and other system components.
• Manage the full firmware lifecycle: development, testing, release, deployment, and updates.
  
  

Hardware Integration

• Interface with various digital and analog sensors (e.g., temperature, pressure, flow) and actuators (e.g., fans, pumps, valves) used in the cooling system.
• Collaborate with hardware engineers on PCB design, providing input and feedback from a firmware perspective.
• Collaborate with hardware engineers on PCB design, understanding at high level and giving feedback.
• Coordinate with PCB manufacturers to ensure designs meet firmware requirements and specifications.
  
  

System Optimization

• Analyze system performance data and optimize control algorithms to maximize cooling efficiency and energy savings in coordination of HW engineering teammates.
• Implement fault detection and diagnostics mechanisms to ensure system reliability.
  
  

Testing And Debugging

• Develop and execute comprehensive test plans for firmware and hardware integration.
• Troubleshoot and resolve issues related to system performance, reliability, and communication.
  
  

Documentation
