How hiring works
- OSCE secondment: national nomination first
Most OSCE field and secretariat security posts are seconded — your capital nominates before Vienna or a mission does.
- INTERPOL NCB endorsement
Lyon General Secretariat posts often need a National Central Bureau letter before the vacancy even counts.
- Applying via USAJOBS for US national-security posts
USAJOBS as the front door for DoD, DHS, and intel-community civil posts — series, clearance, and public vs status.
Reading a vacancy
- Security clearance in Europe
National vetting, NATO COSMIC, EU SECRET, and why a badge from one capital rarely travels unchanged.
- Language requirements for defence and security posts
English as the working floor; French, German, and operational languages as filters, not decoration.
- Cross-system grades: NATO, EU, UN, and national scales
A rough map of A/L/G, AD/AST, P/FS, and civil-service bands so a vacancy grade is readable at a glance.
