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

  • Support process simulation
  • Simulation verification
  • Scenario assumption management
  • Training model documentation

Build proof, not just a list

Simulate a fictional civilian maintenance queue using synthetic demand and staffing data. Compare scenarios and explain which real-world decisions the simplified model cannot support.

How to price this work as a freelancer

Bound nonoperational scenarios, synthetic inputs, verification cases, compute needs, and excluded sensitive or operational uses before contracting. 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 support simulation engineer work. Your personal taxes, location, contract terms, and workload still affect the comparison.

Employee or freelancer?

Working as an employee

Employment may provide approved information systems, specialist supervision, defined program responsibilities, and access to authorized unclassified work. Compare the actual role scope, supervision, benefits, working hours, and access to tools with the cited occupation reference.

Running a freelance business

Independent work can focus on public-source research, documentation, analysis, civilian training, or defined support deliverables when access, review, and contracting boundaries are explicit. For this specialty: Bound nonoperational scenarios, synthetic inputs, verification cases, compute needs, and excluded sensitive or operational uses before contracting.
