Principal Software Engineer, Networking (24180)

Cambridge, Cambridgeshire
to £60k + benefits DoE

C++, networking, high performance, low latency, Cambridge

A top Cambridge company is seeking a skilled C++ software engineer, to principal level, to work on low latency predictive networking applications with high volumes of concurrent users.

The application area is video game technology, for situations where many thousands of simultaneous users are sharing one virtual space. Game state must be replicated across these thousands of agents based on one authoritative source, whilst simultaneously each client is updating the source with its own state.

Your skillset will include extensive practical C++ coding and low latency transport-level networking, particularly with UDP datagrams. An understanding of the implementation (and pitfalls) of connection-oriented protocols such as TCP is important. You’ll have a good degree in computer science or a related subject from a top university and full permission to live and work in the UK without time limit, restriction or sponsorship.

In terms of C++ experience, C is also beneficial and a fundamental understanding of the machine is more critical than (say) awareness of specifics of C++ 17 syntax. OO is used for collaboration and modularity, but performance is critical.

Additional experience of the following would be beneficial: cloud computing (Azure, AWS, or Google Cloud), modern scripting languages, Linux. Games experience is not required.

Interested? Send your CV to ECM Selection; whilst we can only put forward the top few candidates, we do read every CV and try to respond to everyone. Or recommend a friend for £250, details at
