How to get traction and become productive fast at a start-up, when it's a new domain and sw stack & goals are obscure ?
A few things first
This is my first startup gig . Sr SDE. I have 10YOE @ big companies, so still getting used to the usual differences like lack of documentation, process , some infrastructure (in terms of automation , CI , etc ).
To add to the challenges, I'm working in a completely new domain , new software stack and potentially new languages (Java vs Cpp before). I'm closing in on one month and feel the pressure to show productivity and gain confidence from manager and the team.
The goals set for me are very obscure , like "don't restrict yourself to one area, we believe you can add more value across the stack ,etc. "
Any suggestions from people who have done it before on how to navigate this ? It's not easy finding a mentor at a start-up as opposed to a bigger company .
What questions to ask the manager to get the expectations clearer ?
How to get a good command of the same stack with almost no documentation and a vast code base ?
