Questions fréquentes data engineer senior

Quelle différence entre senior et staff engineer ?

Senior : expertise technique, projets complexes. Staff : impact organisationnel, architecture, mentoring. Staff = senior + leadership technique + influence cross-team. Saut salarial significatif (+30-40%).

Faut-il maîtriser tous les outils du marché ?

Non, spécialisation T-shaped recommandée. Maîtrise profonde 2-3 domaines (ex: streaming + cloud). Connaissance générale autres outils. Adaptabilité plus importante que exhaustivité.

Cloud vs on-premise, que privilégier ?

Cloud dominant (90%+ nouvelles architectures). On-premise legacy, réglementaire. Multi-cloud croissant. Focus AWS/GCP/Azure. Kubernetes abstraction portable entre clouds.

Comment évoluer vers staff/principal ?

Impact beyond code : architecture, mentoring, standards. Projets cross-team, influence technique. Communication stakeholders. Publications, conférences. Résolution problèmes complexes organisation.

Real-time vs batch, quelle spécialisation ?

Real-time forte demande, mieux payé (+20-30%). Batch toujours nécessaire, moins différenciant. Idéal : maîtrise des deux, Lambda/Kappa architecture. Streaming-first tendance dominante.

Startup vs Big Tech pour un senior ?

Startup : impact, equity, polyvalence, risque. Big Tech : salaires élevés, ressources, spécialisation, stabilité. Choix selon profil risque, phase carrière. Mobilité possible entre deux.

L'IA va-t-elle automatiser le data engineering ?

Automatisation tâches répétitives (SQL generation). Complexité architecture, business logic restent humaines. Évolution vers higher-level problems. Augmentation capacités, pas remplacement.

Comment négocier un package senior ?

Benchmark marché précis. Multiple offres idéal. Négocier equity, sign-on bonus. Valoriser impact business. Timing budgets annuels. Compétences rares (streaming, ML) premium.

Remote vs présentiel impact salaire ?

Remote souvent équivalent voir supérieur. Accès talent pool global. Économies bureau redistribuées. Quelques entreprises discount remote (-10-15%). Tendance égalisation.

Reconversion vers management ou rester IC ?

Individual Contributor (IC) track viable jusqu'à Distinguished. Management : people, budget, strategy. IC : technical depth, architecture. Choix selon appétence. Réversibilité possible.
