Network & Comms Systems Engineer

Tritanium Space Defence & Technology are looking for a Systems Engineer (Networking & Communications) to design, build, and support the communication networks that power USV and AUV platforms. This role blends systems thinking, hands-on engineering, and real-world deployment that is perfect for someone who loves making complex systems work reliably in challenging marine environments. What You'll Be Doing You'll be responsible for ensuring secure, high-performance data flow between autonomous vessels, motherships, remote operators, cloud services, and onboard sensors. The role combines:Systems engineering - requirements, architecture, integrationNetwork & communications engineering - routing, RF, radios, protocols, data linksHands-on testing & field work - lab setups, bench testing, sea trials This is a role for someone who enjoys building real systems, configuring hardware, solving problems in the field, and making networks behave exactly as intended., Network & Communications ArchitectureDesign and document end-to-end comms architectures for USVs and AUVs (radio, satellite, cellular, mesh, Wi-Fi, acoustic).Develop routing strategies, link redundancy, failover paths, and network configurations.Define and maintain IP schemes, VLANs, firewall rules, QoS, bandwidth allocation, and encryption. Integration & TestingConfigure and integrate routers, switches, modems, radios, antennas, cloud-hosted routers, and onboard compute.Conduct bench tests, HIL setups, and performance diagnostics (latency, throughput, RF quality).Support sea trials to validate real-world communications performance. ️ Operational SupportDiagnose comms failures, interference, and network bottlenecks during development and deployment.Support live missions with bandwidth management, link tuning, troubleshooting, and system reconfiguration. Systems EngineeringProduce requirements, ICDs, test plans, and verification documentation.Run trade studies on new comms technologies (satcom, mesh, acoustic modems).Collaborate with mechanical, electrical, software, and autonomy teams for seamless integration. Client & Project EngagementProvide technical support to operations and project teams.Help design tailored communication solutions for specific missions and environments.

EssentialDegree in Networking, Telecommunications, Electrical/Systems Engineering, Computer Engineering, or similar.Strong IP networking experience (routing, switching, VLANs, firewalls, QoS, VPNs).Knowledge of RF and wireless comms (antennas, propagation, fundamentals).Hands-on experience configuring network hardware (Cisco, MikroTik, Ubiquiti, Peplink, etc.).Understanding of satellite, 4G/5G, Wi-Fi, or RF mesh systems.Experience with cloud-hosted services.Comfortable building, testing, and troubleshooting real hardware.Familiarity with Linux networking tools. DesirableExperience with Ansible, AWS, OpenWRT, WireGuard, RouterOS.Marine communications experience (AIS, maritime radios, acoustic comms).Networking for autonomous systems (UAVs, robots, mobile platforms).Cybersecurity knowledge (secure comms, certificates, hardening).Familiarity with ROS/ROS2 networking, DDS, or middleware.Experience with field deployments and remote operations.
