Transitioning to Engineering Manager
The Hardest Shift
As a Software Engineer, your dopamine comes from solving puzzles and merging code. At the end of the day, you have a tangible feature you built. As an Engineering Manager (EM), your dopamine sources vanish. Your calendar fills with 1-on-1s, alignment meetings, and unblocking team members. At the end of the day, you will feel like you "did nothing," even if you were incredibly productive.
Your Output is the Team
You must realize that your code no longer matters. Your output is now the efficiency and health of your team. If you spend 5 hours coding a feature, you failed. If you spend 5 hours mentoring a junior developer so they can build that feature (and all future features) twice as fast, you succeeded.
Don't Micromanage the "How"
The fastest way to ruin your relationship with your senior engineers is to tell them exactly how to architect a solution. As an EM, your job is to define the "What" and the "Why" (the business context and the requirements). You must trust your team to figure out the "How."
