When accounting for total compensation including base salary, benefits, bonuses, 401k programs, time off, and non-monetary benefits like a clean codebase and positive team, we find our total package exceeds most/all comparable offerings on the market (such as those seen on https://larajobs.com/)
Glassdoor gives $135,000 average for "Senior PHP Developer"
My experience: The lowest I've seen for a Sr. Dev in my area is $120k base salary.
However, this looks like a fullstack engineer since you mention frontend components so that may mean even more.
It's fine to set the pay at whatever you want, but it's objectively low for the role. If you have calculations on what the overall comp would be that would probably help.
“We’re going to pay you less because our code is clean” seems... odd.
Based on your description, this role seems to be more of a Senior Full Stack Engineer, a title with significantly more responsibility than "Laravel Developer."
Until your clean codebase and positive team can pay my mortgage or other bills, I will not factor them into compensation comparisons.
The national average for a senior full stack engineer, according to Glassdoor, is $160k. You could probably argue that Pittsburgh is a lower-cost area than average, but I still think you're 10-20k low in base salary alone, at bare minimum.
