SOFTWARE ENGINEER FRONTEND
This is a hybrid role that requires 3 days/week in our London (Fitzrovia) office
ABOUT LORUM
The structural conflict at the centre of correspondent banking is not technological. It is economic. Banks earn revenue from their balance sheets: they lend deposits, capture FX spreads, and hold funds as long as it is rational to do so. Clearing, the act of releasing funds quickly and predictably, competes directly with those economics. An institution designed to lend has a structural incentive to hold deposits; an institution designed to clear has an incentive to release them. When one institution does both, clearing loses. The result is unpredictable settlement, trapped capital, and a correspondent network shrinking by design.
WHY LORUM
Lorum was founded on a different premise: clearing as the business, not a byproduct. The model has been operational since 2023 and grew 55x in 2025, with USD clearing now the majority of volumes alongside a growing treasury offering. We have applied for a U.S. national trust bank charter. The people we hire now will build the clearing and treasury infrastructure it unlocks.
THE ROLE
We’re looking for a Frontend Engineer to join our web team in London. We’re building new features and teams around Treasury Services and Clearing & Custody, and this role will build the UIs for those products alongside our existing Ops Portal the internal tool that lets the business scale (fee setup and more). This is a backfill on an existing team, so you’ll be able to move quickly and have real impact from day one.
