Also a former Cap1 employee here, the 3 people managing a team of 3 engineers is quite common.
My last team before leaving had 3 engineers: tech lead, me, and a junior dev. It had 4 non-engineers managing us: a product owner, a head Agile Delivery Lead, a more junior agile Delivery Lead, and our manager.
