Senior Engineer – Data Platform Team | C#/.NET, Kafka, Event-Driven / Streaming | Up to £130,000 + Bonus + Benefits | Hybrid | FX Trading Firm | London
I'm currently working with a leading London-based FX trading technology team that is looking to hire a Senior Engineer to join its Data Platform team and help scale a mission-critical, real-time platform powering high-volume electronic trading systems.
This isn't a typical backend development role. It sits at the intersection of high-performance engineering and modern data platform architecture, focused on designing and building distributed systems capable of processing and streaming vast volumes of trading data in real time.
⚡ When market volatility increases, trade and order volumes can surge dramatically within seconds. The platform must remain exceptionally fast, resilient, and fault-tolerant under extreme load. The team is looking for engineers who enjoy solving complex engineering challenges where scalability, concurrency, low latency, and performance are fundamental.
This is an opportunity to work on genuinely large-scale distributed systems where you'll tackle difficult technical problems, influence platform architecture, and build technology that sits at the heart of a front-office trading environment.
💻 Tech Stack
Key technologies include:
- C# / .NET (currently .NET 8 with ongoing investment in the latest .NET versions)
- Kafka or similar event-streaming technologies (RabbitMQ, Kinesis, Azure Service Bus, etc.)
- PostgreSQL and large-scale relational databases
- Real-time data pipelines and distributed systems
- Event-driven microservices architecture
🧠 What You'll Be Doing
- Designing and scaling high-throughput real-time data ingestion pipelines
- Building and enhancing event-driven platform services
- Processing and distributing large volumes of live market and trading data
- Designing resilient, scalable, low-latency backend services
- Collaborating with product owners and engineering teams to deliver production-ready solutions
- Contributing to the technical direction of a highly scalable data platform
