What people at ServiceTitan say
Reviews originally posted on Glassdoor.
Work and life balance. I really mean it, especially with the opportunity to work from remote(from anywhere you want) you can spend your time as you want to.
Challenging tasks, solid product, good people, culture, many opportunities to learn something new. Work/life balance is mostly fine.
Collaborative environment, really smart people that I continue to learn from every day and directors who respect your output and do not micromanage. I get a lot of ownership of my day-to-day and have the opportunity to be hands-on with new product dev.
Plenty of perks. They just keep coming, with the company’a growth the founders like to give and share with the rest of us.
