About this role

Antares seeks a Firmware Engineer to develop embedded control software for next-generation microreactor hardware. You'll design and validate real-time firmware for sensors, actuators, and instrumentation across development and deployment phases, collaborating closely with electrical, controls, and safety teams.

What you'll do

  • Design and develop firmware in C/C++ for microcontrollers and embedded processors interfacing with reactor hardware
  • Implement communication protocols (SPI, I2C, UART, CAN, Ethernet, RS-485) and sensor/actuator control logic
  • Perform hardware bring-up, board-level debugging, and validation using oscilloscopes, logic analyzers, and lab equipment
  • Develop fault detection, diagnostics, telemetry, and system health monitoring firmware
  • Collaborate with electrical engineers on board design reviews, signal integrity, and hardware/software requirements
  • Support hardware-in-the-loop testing, automated test frameworks, and configuration-controlled releases

What they're looking for

  • C/C++ firmware development for embedded systems
  • Microcontroller and real-time platform programming
  • Communication protocol implementation (SPI, I2C, UART, CAN, Ethernet)
  • Hardware debugging and lab instrumentation (oscilloscopes, logic analyzers)
  • Multi-threaded/multi-process software design and IPC
  • Sensor acquisition and actuator control
  • Fault analysis and failure mode handling
  • Hardware-software integration and testing
