This isn’t a typical backend role. It sits at the intersection of high-performance backend engineering and data platform architecture, focused on building distributed systems that process and stream huge volumes of trading data in real time. ⚡ When markets become volatile, trade and order volumes can surge instantly, so the platform needs to remain extremely fast, resilient, and fault-tolerant under significant load.

It’s the kind of environment where you’re solving real engineering problems at scale, rather than just building standard application features. 💻 Tech Stack Key technologies include: • C# / .NET (currently .NET 8 / .NET 10) • Kafka or similar event-streaming technologies (RabbitMQ, Kinesis, Azure Service Bus etc.) • PostgreSQL and large relational data systems • Real-time data pipelines and distributed systems 🧠 What You’ll Be Doing • Designing and scaling real-time data ingestion pipelines • Building and improving event-driven platform services • Handling large volumes of streaming market data • Working with product owners to translate requirements into production-ready systems 💰 Package 💰 Salary: £95K 📍 Location: London (Hybrid – 3 days per week)
