About this role

Antares seeks a Reactor Software Engineer (Level I or II) to develop mission-critical software for operating, testing, and interfacing with next-generation microreactors. You'll build systems that acquire telemetry, execute commands, detect faults, and maintain safe operation across simulation, hardware test stands, and eventual full-scale deployment.

What you'll do

  • Develop data acquisition, telemetry processing, command handling, and fault response software for reactor systems
  • Own features end-to-end from specifications through implementation, integration, testing, and documentation
  • Build software that abstracts real hardware and simulations with consistent interfaces across environments
  • Implement runtime controls including scheduling, event handling, mode transitions, and command validation
  • Design and maintain clear software interfaces for hardware adapters, DAQ systems, sensors, and operator tools
  • Develop fault detection, classification, containment, and recovery logic with comprehensive logging and diagnostics

What they're looking for

  • Python 3 and production software development
  • Hardware integration and embedded systems software
  • Data acquisition, telemetry streaming, and signal processing
  • Fault detection and safety-critical system design
  • State management and command/control architecture
  • Automated testing and hardware-facing test environments
  • Cross-team collaboration on interface definitions and integration
  • Robotics, aerospace, automotive, or mission-critical systems experience
