That's basically how things are where I am. We have a group of ~20-25 developers and everyone reports to one of 4 managers (who are also technical, but that's neither here nor there).
Every project in the group has a tech lead, who may be one of those 4 manager or it might be someone else that's relatively senior. That tech lead is in charge of the folks under them for the purposes of that project.
Any given developer might be working on a single project or sharing time between a few, so they'll have their manager and 1 or more tech leads.
