Full job descriptionAssistant Accountant | High Growth Fintech | London/HybridThe ClientHarmonic are excited to be working with a fast-growing, FCA-regulated consumer credit business that has more than doubled its revenue over the past year and expanded its headcount significantly in the same period. It’s a great stage to join, with real investment going into building out the finance team.
