Seeking advice as a new EM

I recently was promoted to an EM from a Senior SDE role. The EM role is in a new org and domain with a new boss so it’s essentially like starting a new job. While I interviewed originally for a small team of 3 engineers it seems like between interviews and re-org strategy the scope has expanded to 6 engineers and almost 8-9 micro services that I ll be owning. Some of my direct reports have overall experience double than mine. I have admittedly gone really quick up the ladder and wasn’t expecting this at all. Will I not get to code at all? Should I even code at all? What should I focus on? How to handle/lead engineers who are domain experts of the area? Will they even consider me a lead ever? I am a little nervous with so many things happening and not sure how to handle all this and already having huge imposter syndrome. Looking for actionable advice and hearing from people who have been in my shoes before. #engineering #management #software #engineeringmanager
