Simplify Jobs

Simplify's Take

What believers are saying

  • September 2026 job boards show 21 open roles, signaling active contract demand.
  • Roles pay $180,000 to $200,000, attracting scarce TS/SCI-cleared engineers.
  • New 2026 contract awards suggest ongoing recompete wins and pipeline momentum.

What critics are saying

  • Revenue depends on Defense Intelligence Agency and National Geospatial-Intelligence Agency budgets.
  • A single lost SITE III task order can cut headcount quickly in Annapolis Junction.
  • No public diversification into commercial markets creates existential concentration risk.

What makes Red Arch Solutions unique

  • SITE III and OASIS+ position Red Arch inside DIA, NGA, and federal buying channels.
  • Red Arch still markets data modernization, cybersecurity, and cloud for intelligence customers.
  • Its 2004 founding and 51-200 employee scale support niche, cleared-delivery specialization.
