My client are a high frequency trading firm based in London.
They're looking for a back-end Java engineer who will contribute to both sides of the stack.
This isn't a typical full-stack role, your time isn't split between backend and frontend work.
They have a frontend team in place. You will not be designing UI.
Instead, you will build high-performance Java services that power the trading UI. So yes you need frontend awareness, but your focus is on backend engineering that makes the UI fast and reliable.
What you will do:
* Design and build Java services that feed real-time data to the frontend.
* Work with the UI team on transport choices, batching, back-pressure, and error handling.
* Improve end-to-end latency by looking across the stack.
What you'll bring:
* Strong knowledge of computer science fundamentals (data structures, algorithms).
* Java engineering experience in trading, betting, gaming, or streaming.
* Hands-on work with real-time or data-heavy systems.
* Comfortable across server and browser.
Not essential (but nice-to-have):
* Experience with frontend languages.
* Experience with trading systems.
Interview process:
* Microsoft Teams: 45min - 1hr chat.
* On-site interview: Technical interview and coding test.
* Meeting with CTO.
Why join?
The hiring manager started as a grad 10 years ago. Here's how he describes it:
"We have fundamental control about basically every part of the entire technology stack, from widgets in the UI all the way down to kernel level/bypass drivers. We're doing things with FPGAs. There's a place for every level of interest. We've got some things in compiler, compiler-adjacent technologies as well. It energises people who are interested in applying theoretical computer science to practical software engineering tasks."
