Edmonton, Alberta, Canada
Summary
👤
Senior🎓
Top SchoolForrest Zeisler is a seasoned software leader and co-founder serving as CTO of Jobber, where over 14+ years he’s scaled a product that helps small mobile service businesses manage quoting, scheduling, invoicing and payments for billions in annual services. He blends strategic product leadership with hands-on engineering—aligning PM, design and BizOps to turn customer insights into measurable growth while deliberately avoiding being the smartest person in the room. A University of Alberta software engineering graduate, Forrest contributes to the Ruby ecosystem (notably fixes and features in gems like ice_cube and acts_as_list) and has full-stack experience building recurring-event selectors and integrations. He’s equally focused on culture and hiring, having shaped Jobber’s playbook from the ground up, and still spends time solving thorny technical problems or hiring people smarter than himself.
