Scaling Your Engineering Team: From 2 to 20 Engineers

Scaling an engineering team is about more than hiring. It is about creating systems and culture that enable people to do their best work.

At 2-5 engineers: Focus on establishing coding standards, CI/CD, and a strong review culture. At 5-10: Introduce team structures, on-call rotations, and technical documentation. At 10-20: Consider platform teams, architecture review boards, and engineering managers.

The biggest risk is losing velocity during growth. Invest in onboarding, documentation, and developer experience tooling early.
