Senior Payroll Specialist at Sona
- Company: Sona
- Location: Hybrid - London
- Employment type: Full Time
- Posted: 2026-09-21
- Salary: GBP 45000–55000
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.
Responsibilities
Run end-to-end payrolls for a growing portfolio of enterprise customers with complex requirements, spanning hourly rates, overtime, and weekly, fortnightly or monthly cycles
Own your client relationships as their primary point of contact, giving them confidence in our service
Identify opportunities to improve how we work, including where AI can help, and help put those improvements into practice
Act as a payroll expert in support of sales, helping prospective customers understand how our bureau operates
Collaborate across Sona, from Implementation and Product to Customer Success and Support
Develop a strong working knowledge of our HR and WFM platform and how it connects to payroll
Monitor KPIs, SLAs and compliance to ensure we deliver the highest standard of service
Stay current on the legislation, tools and trends that shape how we run payroll
Requirements
Hands-on bureau payroll experience, processing for multiple clients rather than running a single in-house payroll
Strong working knowledge of UK payroll legislation: PAYE, RTI, pension auto-enrolment, and statutory payments
Comfortable managing multiple concurrent payrolls at volume and across different pay cycles
Assured and expert with clients, operating as a trusted advisor on payroll matters
Genuinely curious and self-sufficient: you research, question inefficiencies, and bring ideas rather than needing a playbook handed to you
Genuinely motivated by a startup environment where you help build the processes, not just follow them
Bonus: CIPP qualified (or working towards it), high-volume or multi-sector bureau experience, and any experience building or improving payroll tools and processes, including with AI. A little Ireland payroll exposure is a nice-to-have, not a requirement.
