Northrop Grumman Northrop Grumman · Aerospace · Roy, UT +2 · Software

Northrop Grumman is seeking a Staff Software Integration Engineer to join their team. This role involves designing, implementing, and testing drivers and APIs for embedded systems, integrating software with hardware interfaces, and managing firmware updates. The position requires proficiency in Python, experience with embedded hardware interfaces, real-time operating systems, hardware validation tools, firmware build systems, version control, and CI/CD for embedded systems. Responsibilities include unit/component testing, hardware-in-the-loop testing, system-level testing, automated measurement, and DevOps practices like containerization and artifact management. The role also involves Agile methodologies and strong analytical debugging skills.

What you'd actually do

  1. Designing and implementing drivers/APIs that expose hardware functionality to Python
  2. Using communication protocols (Modbus, MQTT, OPC?UA) to bridge software services and devices
  3. Managing bootloaders, firmware upgrades, and configuration flashing
  4. Hardware-in-the-loop (HIL) testing – automated scripts that program devices, run stimulus, capture response, and assert results
  5. System-level testing – Robot Framework, TestStand, or custom Python harnesses that coordinate multiple subsystems
