At Slalom _build[1], we have People Managers and Team Leads.
Your people manager stays with you as you transition from project to project. They never have more than six direct reports. They are the person that handles all the bureaucracy for you and helping you through the org.
Your team lead is sometimes a people manager but probably not yours. They change based on the project you are on and are responsible for it's success. Their focus is on delivery not your career.
I'm interested in seeing where this goes as it breaks the responsibility up without breaking the career progression. There isn't a "technical path" ... yet.
