I read The Work of a Senior Engineering Leader.
This book speaks to leaders who have stepped up from hands-on engineering into a role that shapes teams and organizations. It addresses the challenges you meet when you shift from delivering as an individual to delivering through others.
It lays out the areas that technical skill alone cannot carry you through: how you delegate decisions, how you set priorities, and how you face stakeholders. Anyone who wavers at the boundary between management and technical leadership will find a signpost here.
The book pushed me to face, ahead of time, the questions I run into as my role widens.
