product designer with 2 years experience and an inflated title needs advice

Went to RISD, dropped out to avoid student loan debt. Moved to SF, took a short course from General Assembly and did contract ui/ux work for a few start ups. One of the contract employers wanted to hire me full time. I was working under their one design director. Company was small but had been operating for 10 years, had a mission I loved, and fully remote which gives me a lot of freedom. 2 months in the design director that hired me left and they asked me to take over. I took the challenge.

I’ve now been working for them for almost 2 full years without a solid design mentor, and the cofounder who I work with directly is a major micro manager (ex: he asks me to change the size and color of headers in prototypes 3x until he thinks it’s just right). I feel like I’m no longer growing in the company but also feel like there’s so much I don’t know about this discipline and want to learn/ need to learn before I move elsewhere.

Bonus is that it’s fully remote and I have a lot of flexibility. Current salary is 120k. I’m now living in Los Angeles if anyone knows of good design mentors or companies with great design culture in this city. Or has general advice on how to proceed in my career with an inflated title and impostor syndrome.
