Senior Software Engineer

Job Title Senior Software Engineer Job Description Senior Software Engineer — Java Order Management System (OMS) — Trading Platform

IG Group is a FTSE 100 fintech operating across five continents, serving over 1.4m customers and handling billions of dollars in transactions – built on scale, trust, and proof. We didn't pivot to innovation; it's how we've always operated. What that means for the people who work here is real: genuinely complex problems to solve, the technology and resources to tackle them properly, and the kind of scope that's rare in established businesses.

The bar is high – bring a curious and forward-thinking mindset and we'll give you the platform to define what comes next.

We are a small, cross-functional team that owns its services end to end, in production. We work closely with product and the business — close enough that “what should this order do next?” is a conversation, not a ticket.

Much of the interesting work lives at the OMS boundary. Because the order flow runs through this service, the OMS describes the business process directly — and that is exactly what makes the role a demanding one, and an unusually influential one.

Your role in the team’s success:

This team owns the Order Management System (OMS), a central part of our trading platform. The OMS controls the order flow for incoming orders: it is where an order’s path through the platform is decided, tracked and recorded. You will join as a senior engineer on that service: designing and building Java services where correctness is not negotiable and latency is measured rather than guessed. When something goes wrong here, the teams who trade and support our clients feel it straight away. We are looking for an engineer who wants the domain as much as the engineering. You do not need to arrive as a trading expert, but you do need to want to become one.
