About the Role

We’re looking for a Senior Billing Specialist to join Swap’s Finance team in Poland. This is an operations role at heart: you’ll own the processes behind our Shipping billing and customer onboarding, make them run accurately every day, and then make them better.

Swap is scaling quickly, and our billing volumes and complexity are growing with us. We need someone exceptionally sharp and process-driven who sees a manual workflow and immediately starts thinking about how to map it, fix it and automate it. You’ll sit within the Billing team, working on the live billing cycle while leading the projects that will transform how it works: implementing new billing tools, consolidating data sources and bringing automation and AI into Finance operations.

This suits someone from a finance operations, operations analyst, business operations or founder’s associate background who is analytical, systems-minded and comfortable getting into the detail. There’s no fixed ceiling on scope here, and the role will evolve with your skills as Swap grows.

Key responsibilities
Own and improve billing operations

• Own the end-to-end Finance onboarding process for new customers, including billing setup, Direct Debit mandates and customer data, and identify where it can be simplified or automated

• Prepare and review Shipping billing calculations, resolving customer and internal queries and tracing root causes rather than only fixing symptoms

• Perform billing reconciliations and exception investigations, maintaining accurate records and clear documentation

• Run first-invoice reviews for newly onboarded customers and feed learnings back into the onboarding process

• Support customer termination and churn processes, including termination fee calculations and coordination with Credit Control

Build and implement

• Lead the implementation and testing of new billing tools that consolidate data and replace manual processes

• Map, document and redesign billing workflows, defining requirements, tracking issues and driving changes through to completion

• Drive the adoption of automation and AI-enabled workflows across billing, reconciliations and exception identification

• Build reporting and data checks that improve visibility, controls and data quality across the billing process

Support the wider team

• Provide general Billing and Credit Control support as needed, working closely with Finance, Operations and Product colleagues

What we’re looking for

• A background in finance operations, business or operations analysis, systems or process improvement, or a founder’s associate / chief-of-staff style role. Direct billing experience is helpful but not essential

• Exceptional analytical ability and a track record of quickly understanding complex processes and data

• Strong process thinking: you naturally map workflows, spot inefficiencies and design cleaner, more scalable ways of working

• Strong Excel/Google Sheets skills and confidence with large datasets; SQL, BI tools or scripting experience is a real plus

• Hands-on experience implementing, configuring or testing business systems (billing platforms, ERPs, CRMs or workflow tools)

• Genuine curiosity about automation and AI, ideally with examples of where you’ve applied them to improve how work gets done

• Experience with transactional or usage-based billing is beneficial

• High attention to detail and a rigorous approach to accuracy and controls

• Clear written and verbal communication, with the ability to work with stakeholders across Finance, Operations and Product

• Ownership mindset: you take initiative, work with minimal supervision, and are comfortable with ambiguity in a fast-changing scale-up environment

• You’re as comfortable resolving a single billing exception as you are redesigning the process that caused it
