Senior Software Engineer

Overview of the role

• This role sits in the Banking and FX tribe, which owns payment processing, FX pricing and trading, the ledger, reconciliation, bank integrations, FIX engine connectivity, payment compliance and the client portal. Between them, that covers the movement of client money end to end and everything clients see while it happens.
• You will be building services in .NET 10 on Azure, mostly asynchronous flows that have to stay correct when a banking partner times out halfway through or when the same message arrives twice. It's an end-to-end banking platform, so the work spans all of it rather than one corner: payments, FX, the ledger, reconciliation, integrations, compliance and the portal. Wherever it lands, getting it right beats getting it out.
• You make the design calls on your domain and argue them out with the tribe. You build it, you run it, you own it. Services stay with the engineers who wrote them, which means you're trusted to build them your way.
• The role is hybrid, with 2 to 3 days a week in our London office.
