Trading Systems Engineers

About the role

Trading Systems runs the infrastructure Flow Traders trades on: the global Linux fleet — trading servers, workstations and VDIs — and the multi-cloud and distributed-systems estate that sits alongside it. We also build and run the self-service infrastructure platform the rest of Technology depends on.

We are hiring two engineers into this team. This is a hands-on engineering role: most of your time goes on writing Terraform, building CI workflows and guardrails, automating toil out of the Linux fleet, and operating what you build. A lot of the shared tooling does not exist yet, and building it is the job rather than a side effect of it. The environment is trading-critical and runs across both on-premise infrastructure and public cloud, and you will work on both sides of that line rather than specialising in one.

To be clear about the shape of the seat: this is build-and-operate rather than architecture, strategy or management. There is architecture in it, but the bulk of the work is hands-on and there are no direct reports. A solid Linux foundation is essential across the whole role — it underpins both sides of the estate, and the cloud, container and Kubernetes work rests on it just as much as the on-premise fleet does.

What you will do

• Write, debug and publish reusable Terraform modules
