Job Description

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 individual 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 name spaces. 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.
