As the company grows, this role has a path to grow into a technical leadership position for the embedded discipline.

Responsibilities

• Design, implement, and maintain bare-metal and RTOS-based firmware (STM32 / FreeRTOS) for engine controllers, supervisory/system controllers, power electronics, and monitoring systems.


• Develop and support embedded Linux platforms, including system services, networking, and device integration.


• Own productization aspects of firmware: bootloaders, over-the-air / field firmware updates, secure boot, flash and file systems, watchdogs, and low-power operation.


• Integrate and support communication interfaces: fieldbus protocols (e.g., Modbus RTU/TCP, CAN, RS-485), remote connectivity (e.g., cellular/LTE), and cloud telemetry (e.g., MQTT, HTTP) feeding the Qnergy Dashboard.


• Debug complex cross-domain issues using lab equipment (oscilloscope, logic analyzer, debuggers) and contribute to hardware design reviews and board bring-up.


• Collaborate with electrical, mechanical, and cloud/software teams on architecture, interfaces, and design tradeoffs.


• Establish and improve engineering practices for embedded development: version control, code reviews, automated builds, CI/CD for firmware, hardware-in-the-loop testing, and effective use of modern development and AI-assisted tooling.


• Support manufacturing, field service, and customer-facing teams in diagnosing and resolving issues from returned or deployed units.


• Document designs, interfaces, and test procedures to a standard appropriate for safety and reliability-critical products.

Requirements

• Education & Experience:
  
  
  
  • 7+ years of professional experience in embedded systems, firmware, or embedded software development.
  
  
  • Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field – or equivalent practical experience.
  
  
  • Experience shipping embedded products that operate in the field (industrial, IoT, energy, automotive, aerospace, or similar).
  
  
  • Experience taking products from development through certification, manufacturing, and field deployment is a strong plus.
  
  
  
  

Must-have

• Skills & Abilities:
  
  
  
  • Strong proficiency in C (and/or C++) for resource-constrained, bare-metal and RTOS environments.
  
  
  • Hands-on experience with STM32 (or similar ARM Cortex-M) microcontrollers and FreeRTOS (or a comparable RTOS).
  
  
  • Working experience with embedded Linux (e.g., OpenWrt, Yocto, or Buildroot-based systems), including device configuration, networking, and cross-compilation.
  
  
  • Experience with bootloaders, OTA/firmware update mechanisms, secure boot, and flash/file system design.
  
  
  • Proficiency with common communication buses and protocols: UART, SPI, I2C, CAN, Ethernet.
  
  
  • Able to read and interpret schematics and datasheets.
  
  
  • Comfortable debugging with lab equipment: oscilloscope, logic analyzer, JTAG/SWD debuggers, and multimeters.
  
  
  • Solid understanding of embedded system fundamentals: interrupts, DMA, timers, ADCs, power management, and memory-constrained design.
  
  
  • Disciplined engineering habits: version control (Git), code reviews, and structured testing of embedded code.
  
  
  
  

Nice-to-have

• Ability to contribute to hardware design: schematic review, component selection, and board bring-up.


• Experience with PCB design tools (e.g., Altium, KiCad).


• Experience with industrial fieldbus protocols (Modbus RTU/TCP, CANopen) and RS-485 networks.
