Senior Payroll Specialist

Frontline work keeps the world running. Restaurants, hospitals, schools, nurseries, airlines, stores, emergency services. Together they employ 80% of the global workforce, over 3 billion people, and they're among the hardest businesses anywhere to run. By-the-minute scheduling, HR and payroll make them far more operationally complex than the average office, yet just 1% of venture funding has ever gone to software built for them.

Rising costs, wage increases, labour shortages and tighter regulation have made fixing that urgent. Sona is the AI-native workforce management platform for frontline organisations, with agents that match staffing to real demand and take the admin load off managers. That's a $500bn+ market the software industry has mostly walked past.

We've raised over $100M from N47, Felicis, Gradient and Northzone, signed more than 100 enterprise customers across the UK and US, and opened offices in London, New York, Austin and Lisbon. More on working at Sona here.

About the Role

We're growing our payroll bureau fast, and hiring Senior Payroll Specialists to own payroll processing and the customer relationship end-to-end for a portfolio of Sona's frontline customers.

This isn't a conventional bureau role. We're a fast-moving startup where everyone has a hand in building our processes, tools, and ways of working, and we're already more AI-forward in how we run payroll than any other bureau we know. You'll help push that further, not just keep up with it.

If you want a highly structured environment with the playbook already written, this likely isn't the fit. If you're energised by building, and by figuring out where AI genuinely helps rather than just following a process, you'll have real ownership and real opportunity as the bureau scales.
