The Ultimate Guide to Onboarding Software Engineers

The article says onboarding software engineers is hard because it involves many unknowns, emotional pressure, and mismatched expectations about how quickly a new hire should contribute. It treats onboarding as a shared responsibility that starts before day one and needs support from the manager, the buddy, and the wider organization.

It also separates onboarding into team, organization, and culture, then recommends practical help such as a buddy, regular feedback, checklists, and a single welcome document. The framework then uses 30, 60, 90, and 150 day milestones to check understanding of role, tools, team goals, business context, success measures, and level expectations.
