Tech Lead Best Practices

These tech lead best practices are for engineers who have been asked to lead the technical work of a team, often without a formal management title and usually while still expected to write code. The jump is harder than it looks. The skills that made you a strong individual contributor, such as deep focus, fast solo delivery and owning the hardest problems yourself, can work against you once your job is to make a whole team effective.

The guide is checked against sources that describe how well-run engineering teams actually operate: Google's public engineering practices on code review, the Google SRE book's chapter on blameless postmortems, Google's re:Work research on what makes teams effective, a widely cited description of design docs at Google, and the Architectural Decision Records community. Where they give specific guidance, such as responding to a review request within one business day or keeping changes to around 100 lines, the guide says so and links the source.

The first chapter covers defining the role itself, because most tech lead trouble starts with unclear expectations. Later chapters cover technical direction and decision records, planning and execution, code review, growing the people around you, incidents and postmortems, and communicating with stakeholders outside the team.

Each chapter ends with a short quiz. The advice applies whether you lead three engineers at a startup in Lahore or a platform team at a large company in London, and whether the role is called tech lead, lead engineer or team lead.
