開発者には複数のキャリアパスがある。特に個人貢献者(IC)トラック(技術的に成長)とマネジメントトラック(人材育成)が挙げられ、専門化、アーキテクチャなど他の選択肢もある。キャリアパスを理解することで、成長を意図的に方向付けることができる。
2つの主要なトラック
INDIVIDUAL CONTRIBUTOR (IC) → grow as a technical expert (without managing people):
junior → mid → senior → staff → principal → distinguished engineer
→ deeper technical expertise, larger scope/impact, technical leadership, architecture,
influencing across teams (a real senior path — not everyone must manage)
MANAGEMENT → lead and grow PEOPLE/teams:
→ team lead → engineering manager → director → VP → CTO
→ focus shifts to people, process, strategy, delivery (less hands-on coding)
→ both are valid, valued senior paths → choose based on what you enjoy/are good at.
