I was confused by why "use of AI" was a top-level requirement of this, but I see now that weave is AI-driven "engineering output measurement" company, down to the individual contributor level.
I can understand why you would have better luck hiring eager new-grads than seasoned engineers. I'm sure some IC find the weave stats useful, but it also sounds like a toxic manager's dream. I can understand why more senior engineers would steer clear.
