1. Why Is Hiring Aerospace and Defense Engineers So Difficult?

Aerospace and defense recruitment is fundamentally different from generalist hiring. Employers often need professionals who combine advanced engineering knowledge with experience in complex, mission-critical systems.

A systems engineer with satellite integration experience, an RF engineer familiar with space-qualified hardware or an embedded software developer experienced in safety-critical applications cannot always be replaced by someone with a similar job title.

Five challenges facing aerospace startups and SMEs

  1. Small specialist talent pools. Relevant expertise is concentrated in particular companies, programmes and engineering clusters.
  2. Competition from established employers. Large aerospace manufacturers and defense contractors compete for many of the same skills.
  3. Limited internal recruitment capacity. A startup may have no dedicated recruiter or technical talent acquisition team.
  4. Complex technical requirements. Engineering standards, verification experience, system architecture and programme heritage can be essential selection criteria.
  5. Security and eligibility restrictions. Certain defense roles require additional checks, clearances or export-control assessments.

For growing businesses, an unsuccessful recruitment process can affect product development, customer delivery and engineering capacity.

What should a CEO or CTO do first?

Before launching a search, distinguish between the skills that are genuinely essential and those that can be learned after joining. This single decision can significantly expand the relevant candidate market.
