Overview
Expleo is standing up a new Algorithms & Infrastructure Engineering team to support Underwater Systems (UWS) in Cheadle. This is a collective capability build rather than isolated placements — the team will operate collaboratively across containerisation, networking, and virtualised computing domains to deliver secure, high-performance environments for advanced sonar and mission systems.
Responsibilities
* Architect and manage secure network infrastructures supporting containerised and virtualised workloads.
* Lead on the integration of Kubernetes, Docker/Podman deployments into air-gapped defence networks.
* Configure and optimise Linux systems for high-throughput, low-latency environments.
* Design and maintain network segregation, VLANs, routing, and multicast configurations for constrained military environments.
* Support virtualisation platforms (KVM, QEMU, hypervisors) and their interaction with networking layers.
* Collaborate closely with software and algorithm engineers to ensure seamless system interoperability.
Essential Skills
* Expert Linux networking and system internals knowledge.
* Deep understanding of TCP/IP, UDP, multicast, VLANs, routing, and network namespaces.
* Proven experience integrating containerised workloads into secure, distributed environments.
* Familiarity with defence-grade or air-gapped systems and corresponding security practices.
Experience
* Exposure to naval/sonar mission systems or similar real-time data environments.
* Experience with firewalling, ACLs, and encryption technologies.
* Network performance monitoring and optimisation within virtualised or containerised systems.
