We're looking for a skilled Core Ledger Specialist to join our platform team. Our team does not develop the core ledger systems ourselves - they are built and delivered by external suppliers. Your role is to understand the business and financial logic deeply, define and write clear requirements, verify and regression test what our suppliers deliver, and support internal configuration of the platform. A significant part of this role is providing hands-on internal support to colleagues across the business who rely on the core ledger day-to-day - this is something all specialists in the team spend a lot of time on. This role calls for strong analytical and technical skills combined with a good understanding of how financial ledgers work.
You will join a small, close-knit team: today the Core Ledger team consists of a Head of Core Ledger IT, a Product Manager, and two Core Ledger Specialists (one of whom also carries delivery management responsibilities). This is a great opportunity to make a direct impact early on and help shape the team as it grows.
