salary benchmark —
What does a senior IT expert really cost, in France and in Belgium?
The tightest niches — Infrastructure & Cloud, Cybersecurity, Data & AI — read across two markets and two seniority levels. Every figure is dated and tied to a named source.
Where do these figures come from?
Salaries come from dated public sources: recruitment firm salary guides (Robert Half, Factoriel) for France; specialist aggregators (Jobicy, ERI SalaryExpert) for Belgium, flagged with a ~ and to be read with care while we consolidate them. No IT services provider publishes assignment day rates by role and seniority: we estimate them from the fully loaded employment cost multiplied by ~1.7, cross-checked against published freelance day rates (Free-Work, Silkhom).
