About Us STARK is a new kind of defence technology company revolutionizing the way autonomous systems are deployed across multiple domains. We design, develop and manufacture high-performance unmanned systems that are software-defined, mass-scalable, and cost-effective. This provides our operators with a decisive edge in highly contested environments. We’re focused on delivering deployable, high-performance systems - not future promises. In a time of rising threats, STARK is bolstering the technological edge of NATO Allies and their Partners to deter aggression and defend Europe - today. Your mission Engineer, build, secure, and maintain mission-critical network connections between autonomous aerial, waterborne, and ground systems and NATO-grade command centers, ensuring reliable, low-latency, and secure transmission of telemetry and high-bandwidth video with zero compromise on operational safety. Responsibilities Integrate and optimize resilient data links to ensure high availability across ground control station (GCS) environments. Harden network infrastructures by implementing and optimizing security features across network devices and Linux-based workstations, including OS and port hardening and ACL management. Lead network performance optimization efforts to minimize latency and maximize throughput for real-time visualizations and sensor streams. Act as the escalation point for network performance issues, conducting advanced diagnostics using tools such as iperf, Wireshark, tcpdump, and other CLI-based analysis tools to resolve jitter, packet loss, and throughput constraints. Support the completion and integration of ground control stations in line with Bundeswehr (Bw) requirements. Collaborate with UAV development teams on radio data links between drones and ground control stations across different platforms and operational scenarios. Contribute to defining network engineering standards, documentation, and review processes to establish best-in-class practices. Qualifications 7 years of professional experience in network engineering Proven hands-on experience implementing and optimizing IPv4 and IPv6 in production network environments. Experience integrating 4G/5G connectivity into enterprise or tactical architectures, including APNs and cellular signal optimization. Strong background in securing and hardening network infrastructures, including ACLs, OS hardening (Cisco IOS-XE, Juniper Junos, Arista EOS), port hardening, and Linux-based systems. Expert-level proficiency with Wireshark (stream analysis, protocol decoding), iperf (throughput testing), and related network diagnostic tools. Ability to obtain EU/NATO security clearance. Strong hands-on mentality with a practical problem-solving mindset. Ability to work effectively within a small, highly collaborative team and communicate clearly across technical disciplines. Nice to have: Experience in high-stakes environments such as defense or telecommunications. Knowledge of radio systems and antenna setups. Familiarity with tactical data links (e.g., Link 16), MANET, or SATCOM integration. Relevant certifications such as CCNA (Routing & Switching or Security) If you´re intersted in building the future of European Defence with us, and you see yourself reflected on the description above, please send us your CV in English. We´re looking forward to meeting you.
