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.



Key Responsibilities Define and
document clear, detailed requirements for transaction processing,
balance management, and posting logic, to be delivered by external
suppliers Verify and regression test supplier deliveries to ensure
data integrity, accuracy, and consistency across all ledger
operations Collaborate with the Head of Core Ledger IT and
suppliers on solution design and technical decisions Investigate
and resolve complex ledger-related incidents and data
discrepancies, working with suppliers when needed Maintain clear
documentation, including requirements, data flows, test results,

customer service, operations, and others) on day-to-day ledger
questions and issues — this is a significant and ongoing part of
the role Support integration of new products and financial
