But at the same time "established SV companies" are already paying so much for labor costs that probably they don't want to hire anyone to run a DC for them.
Just task their existing staff to “run the dc”. Way easier to figure this out than grinding leetcodes if you ask me. Also you can rent pretty much everything in that chain these days so your existing “infra engs” can manage soft layer while you outsource all the management of hardware and below.
