Salary at this grade

Basic monthly salary at AST4 runs from €5,438 (step 1) to €6,153 (top step), giving an annual range of roughly €65,256 to €73,836 before tax and allowances. Steps increase automatically every two years; the figures here are taken from the salary grid in the EU Staff Regulations.

Eligible staff posted away from their country of nationality also receive an expatriation allowance worth 16% of basic salary (around €870 per month at step 1 of AST4) together with household, dependent-child, and education allowances where applicable. Take-home pay is then adjusted by the country correction coefficient for Luxembourg. For a worked example see our correction coefficients guide and the EU salaries overview.

Application timeline

This vacancy was first listed on 16 July 2026, 6 days ago.

The application deadline is 17 August 2026, 24 days from today. Late applications are not accepted, so submit through the official EU Careers portal well in advance.

Last verified against the EU Careers feed on 23 July 2026.

Net pay at this grade

At step 1 of AST4, gross monthly basic salary on the Assistants grid is €5,438. Eligible expatriate staff add a 16% expatriation allowance on top (roughly €870 per month) before two automatic deductions reduce the taxable base: the joint sickness insurance scheme (JSIS, ~3.6%, €227) and the EU pension contribution (~10.3%, €650). EU community tax (Council Reg. 260/68) is then applied progressively; for the AD7-equivalent band the effective rate sits in the 11 to 13% range, which works out to about €652 per month here.

Luxembourg carries a correction coefficient of 100.0% (Article 64 of the Staff Regulations), so the net is multiplied by 1.00 to reflect the local cost of living. On those assumptions take-home pay is approximately €4,779 per month, or about €57,353 per year, before household and dependent-child allowances, which can add several hundred euros monthly for staff with families. For the exact bracket-by-bracket computation see our net-pay methodology, and our correction coefficients guide for the full duty-station table.

Comparable recent roles

Pattern recognition matters here: recruiters at the same Directorate-General often re-advertise nearly identical profiles every six to nine months, so candidates who miss one window can typically position for the next one.

Career trajectory

Career progression for AST4 staff is governed by Articles 44 to 46 of the Staff Regulations (consolidated text on EUR-Lex) and Annex IB on the promotion procedure. Step increases are automatic every two years (Art. 44); grade promotion is competitive, based on the appraisal exercise (Art. 45) and the Career Development Review. For roles at European Commission, AST grades progress one level every three to five years on merit; AD reclassification via a CAST or internal competition is the longer-term route. Article 46 governs the classification at recruitment, which sets the starting step within the grade (usually step 1 for external recruits without prior EU service, step 2 or 3 where relevant professional experience is recognised).

Mobility within the institutions is encouraged via the inter-institutional and intra-institutional vacancy publication system: temporary agents who pass the probation period and reservists from EPSO laureate lists can typically apply to internal vacancies after one year of service. Lateral moves between Directorates-General reset the seniority clock for promotion only if the new post carries a different grade.

Language profile

Beyond the formal language requirements stated in the vacancy notice, the day-to-day working languages at this employer are English and French in roughly equal measure, with German appearing in some technical files. Internal meetings and most policy drafting in Brussels run in English; French remains the preferred internal language in Luxembourg-based services and parts of DG TRADE.

Application cadence

Only one comparable AST4 role at European Commission has been advertised in the past twenty-four months. Roles at this signature reopen rarely on the EU Careers feed; do not bank on a near-term repeat opening if this competition is missed.
