Working in this sector

Portfolio work should remain fictional, public, civilian, and unclassified; do not use restricted technical data, operational military scenarios, weapons instructions, or claims of clearance or official authorization.

Skills that make the work valuable

  • Systems requirements traceability
  • Interface control documentation
  • Verification planning
  • Requirements review facilitation

Build proof, not just a list

Create a fictional civilian training-system specification with interface tables and verification methods. Identify ambiguous requirements and demonstrate how a change affects related tests and documents.

How to price this work as a freelancer

Define unclassified system boundaries, document access, review gates, and verification artifacts; exclude classified or operational design work. Agree the inputs, deliverable, review rounds, and acceptance criteria before quoting. Include preparation, specialist review, equipment or licensing costs, and handover time where relevant. Price ongoing support separately from the initial engagement.

Start with the income you need to replace

Required hourly rate = (target salary + benefits budget + annual business expenses) ÷ (annual billable hours × share of revenue retained after fees).

For illustration, $100/hour × 25 billable hours/week × 48 working weeks = $120,000 revenue. After $20,000 in business expenses, that leaves $100,000 profit before personal taxes. Replacing a $100,000 salary plus $15,000 in benefits under those assumptions takes $112.50/hour, with no percentage fees.

These are editable planning assumptions, not rates surveyed for defense systems requirements engineer work. Your personal taxes, location, contract terms, and workload still affect the comparison.
