I definitely agree with this and want to add that coding _well_ is difficult for people of all experience levels, it's not something developers get nailed down their first couple years of working and then have forever. But producing excellent code that is easy to work with can help with the culture part. I've worked with very knowledgeable and experienced engineers that could crank out plenty of buggy and convoluted code that caused other people headaches. Writing clean and well designed code makes coworkers lives easier.
