Lead Software Engineer (Golang) – Real Time Data Platform

This is a hands‑on Lead role focused on designing and building distributed backend systems that ingest, process and serve high‑throughput data, for a well established FinTech.

The platform is already live, but there’s a clear need to evolve parts of the architecture to improve scalability, performance and reliability. This is where the role comes in.

The Role

You’ll join a small, experienced engineering group and take ownership of critical backend services, with a particular focus on Golang.

You’ll work on:

  • Processing and distributing high volumes of real‑time data
  • Improving performance and reducing latency across services
  • Evolving existing architecture toward more efficient patterns

What They’re Looking For

  • Strong experience building backend systems in Golang
  • Solid understanding of distributed systems and event‑driven architectures
  • Experience working with high‑throughput / low‑latency systems
  • Comfortable owning services end‑to‑end, from design through to production
  • Ability to identify problems in existing systems and drive improvements

Tech Environment

  • Legacy backend stack is mainly in Node, which they are transitioning to Go
  • Event‑driven architecture, messaging systems and cloud‑based infrastructure, currently migrating to GCP
  • A pragmatic engineering culture focused on delivery and ownership

Additional Info

  • This is an in‑office role (London)
  • You’ll be working closely with senior engineers and leadership on critical platform components
  • Strong compensation package including base, bonus and meaningful equity that is liquid
