Senior Engineer – Data Platform Team | C#/.NET, Kafka, Event Driven / Streaming | Up to £95,000 + Bonus + Benefits | Hybrid | FX Trading Firm | London

I’m currently working with a London-based trading technology team that’s looking to bring in a Senior Engineer within their Data Platform team to help scale a real-time platform powering high-volume trading systems.

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.

The team is looking for engineers who enjoy working on complex systems where scalability, concurrency, and performance really matter, particularly within event-driven and streaming architectures.

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
