Career trajectory

Career progression for this grade 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 SESAR 3 Joint Undertaking (S3JU), progression to the next grade typically takes three to five years on merit, with two-yearly step increases in between. 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

SESAR 3 Joint Undertaking (S3JU) has not advertised another comparable role with the same grade and Transport signature in the past twenty-four months — this opening has rarely been seen on the EU Careers feed and may be the first such posting in our two-year window. Applicants who pass the eligibility checks should not assume the same profile will reopen on a predictable cadence.
