Day 1 on the Space Systems Engineer path.

What a Space Systems Engineer does

Plans and connects spacecraft parts so teams build a space system that meets mission needs and passes testing.

  • Define mission needs and turn them into clear system requirements
  • Manage interfaces between subsystems like power, thermal, avionics, and structures
  • Build system budgets for mass, power, data rate, and performance margins
  • Run trade studies to compare design options and choose a balanced solution
  • Plan verification and validation tests to prove requirements are met
  • Coordinate reviews, track risks, and resolve cross-team technical issues
  • Maintain system documentation, change control, and configuration baselines

A day in the life

  1. Review open risks, requirement changes, and interface questions from teams
  2. Join subsystem standups to unblock issues and align on next tests
  3. Update requirement traces and verification plans after design decisions
  4. Prepare for design reviews by checking budgets, margins, and open actions
