Job summary

Antares is seeking a Senior Firmware Engineer to build embedded software for our first-of-a-kind microreactor hardware. You will translate sensor signals, device commands, timing, diagnostics, and fault responses into reliable hardware-level behavior.

You will develop firmware for embedded controllers, data acquisition, and test hardware, defining initialization, monitoring, and control across development stages.

Qualifications

• Bachelor’s degree or higher in a technical field.
• 5+ years of production software experience for hardware-integrated or mission-critical systems.
• Experience with multi-threaded or multi-process software and IPC, networking, or message passing.
• Experience integrating software with sensors, controllers, and hardware interfaces.
• Strong debugging across software, hardware, and system boundaries.

Responsibilities

• Design, develop, test, and maintain firmware for reactor instrumentation, control, monitoring, and electrical support systems.
• Develop embedded software in C/C++ for microcontrollers and real-time hardware platforms.
• Bring up new hardware, debug board-level issues, and validate firmware with lab equipment.
• Implement communication interfaces (SPI, I2C, UART, CAN, Ethernet, RS-485).
• Develop firmware for sensor acquisition, actuator control, telemetry, diagnostics, and fault detection.
• Collaborate with electrical engineers on schematics, board design reviews, and signal integrity concerns.
• Ensure firmware supports safety, reliability, and regulatory requirements.
• Participate in design reviews to ensure traceable, testable firmware designs.
• Support hardware-in-the-loop testing and automated test frameworks.
• Develop firmware test plans and documentation for releases.
• Analyze failure modes and define safe states with fault-handling logic.
• Drive root-cause investigations through bench testing and system-level debugging.
