Administrateur système resume: template, ATS keywords, mistakes to avoid

The complete guide to building a Administrateur système resume that passes ATS filters and holds recruiters' attention.

The essential point: La frontière avec le DevOps est de plus en plus fine : l'admin système qui automatise (infrastructure as code) et scripte ses tâches répétitives prend une longueur d'avance et accède aux postes les mieux payés. Celui qui clique encore manuellement plafonne.

Recommended resume structure

Recruiters scan a Administrateur système resume in 7 seconds on average. The top third must carry 80% of the signal. Here is the order that works best for this job:

  1. 1

    Header

    First name + last name, Administrateur système title (or equivalent: Administrateur systèmes et réseaux, SysAdmin), email, phone, LinkedIn, city.In France: no mandatory photo, no age, no family status.

  2. 2

    Professional summary (3-4 lines)

    The hook — what you do, for whom, with what standout result. Avoid empty adjectives ("passionate", "dynamic"). Place 2-3 priority ATS keywords here.

  3. 3

    Professional experience

    The most-read section. Each experience follows the STAR structure: Situation / Task / Action / Result. Prioritize the responsibilities tied to the target job posting.

    • 3-5 bullets per role maximum
    • Each bullet: action verb + object + quantified result
    • Typical responsibilities for a Administrateur système: Administrer les serveurs Linux ; Automatiser le déploiement, la ; Gérer les sauvegardes et...
  4. 4

    Education

    Prioritize the most recent and most recognized degree. For a Administrateur système, the most valued credentials are: BUT Réseaux et Télécommunications, École d'ingénieur (spécialité système/réseau).

  5. 5

    Technical skills

    A precise, categorized list (technical / tools / languages). Avoid percentage charts: ATS don't read them.

  6. 6

    Certifications & projects (optional)

    Recognized certifications, published personal projects (GitHub, portfolio, blog). For a Administrateur système, this is often what sets two equivalent junior profiles apart.

Caution: don't copy the whole list. Only include keywords for which you have real experience — a recruiter who reads "SAP" expects you to be able to discuss it.
