  • 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
