Senior Vibe Coder", how do I improve?

Title is not a joke. I'm only 2 YoE but got a new job as a "Senior Software Engineer" at a tiny <40 people company (I took the job because this company has much more room for growth and the TC was higher + fully remote). The IT Director that hired me knows very little about actual code and just uses apps like Replit/Lovable to develop on and asks me to develop on them as well. Looking at the apps, many of them are a mess. I am basically the only person here who knows anything about software development. Because of this, I have no mentor and I'm not sure how I can really "improve" as an engineer. Day-to-day, I just put prompts into the prompt window until I get the feature or new app working like how I wanted. I genuinely feel my coding abilities atrophying and I'm forgetting information about different frameworks and coding practices, it's all just become: "Put it into the prompt -> View response -> repeat until it looks good". Anyone ever been in a similar situation? If so, how do you improve?
