Customer Success Manager

Job description

Running a frontline business is an operational puzzle most software has never touched. Shift-by-shift labour costs, compliance that changes by region and by role, and margins thin enough that a badly built rota can sink a quarter. It's a harder problem than most white-collar SaaS, and yet frontline sectors employ 80% of the global workforce and have received about 1% of the last decade's software investment. We think AI is what makes the problem solvable; better software alone wasn't enough. Frontline organisations sit on enormous amounts of operational data. Used properly, that data lets agents take on real parts of running the business rather than just reporting on it. That's what we're building at Sona, and it's early enough that the systems you build now will still be foundational in three years.

Everyone holds an important seat and is expected to perform at an elite level. We have each other's backs, we assume good intent, and we have zero space for internal politics. If that's your default, you'll thrive here. This is an on-site role. Four days a week you'll be in our London office or out with customers, with one day working from home. Regular travel to customers across the UK is part of the job.
