FAQ
Do PMs need to be engineers to build devtools?
Not strictly required, but you must be able to read code, use the product yourself, and ship a working integration in under an hour. If you can't dogfood your own product, you cannot PM it well. Engineer-PMs have an edge but are not the only profile that works.
