Day 1 on the Systems Integration Engineer path.

What a Systems Integration Engineer does

Brings hardware and software parts together, tests how they work as one system, and fixes interface issues so products run reliably.

  • Plan how subsystems connect, including signals, data, power, and physical interfaces
  • Write and review interface requirements, assumptions, and acceptance criteria
  • Build integration plans, test setups, and step-by-step bring-up procedures
  • Diagnose failures across teams using logs, measurements, and controlled experiments
  • Coordinate changes across hardware, firmware, and software to resolve conflicts
  • Run system-level tests and track defects to closure with clear evidence
  • Document configurations, wiring, versions, and known issues for repeatable builds

A day in the life

  1. Review test results, failures, and open issues, then set priorities for the day
  2. Meet with hardware and software teams to align on interfaces and change impacts
  3. Integrate a new build, run bring-up checks, and capture logs and measurements
  4. Reproduce a bug, narrow the cause, and propose a fix with a verification plan
