Design, integrate and validate radio and IP network solutions for state-of-the-art air defence systems – from system architecture and test planning through to first deployment in the field.
Your Role & Responsibilities
-
Develop, integrate and optimise systems and components with radio communication, including their integration into tactical IP networks
-
Create concepts, architectures (HLD/LLD), specifications and test plans for systems and components, with a focus on VHF/UHF data links
-
Act as subject matter expert for radio and network configurations, covering IP switching and routing, virtualisation and secure communications
-
Analyse, model and simulate radio and antenna systems, and develop antenna concepts for platforms such as vehicles, shelters or containers
-
Plan and perform system tests, performance analyses and validations in the lab and in the field (e.g. EMC, antenna characteristics, RF performance, interference)
-
Develop test tools, define KPIs and prepare factory and site acceptance tests (FAT/SAT)
-
Perform advanced troubleshooting of complex communication systems
-
Engage with customers, suppliers and external partners to define new technical features and evaluate equipment
-
Carry out requirements engineering with full traceability (e.g. IBM DOORS NG)
-
Support on-site first deployments, commissioning and troubleshooting
-
Collaborate with interdisciplinary teams across the customer, suppliers and internal departments
-
Create and maintain technical documentation (specifications, test reports, operation manuals)
Required Technical & Professional Expertise
-
Degree in Electrical Engineering, Telecommunications, Communications Engineering, Computer Science or a comparable field
-
At least 5 years of professional experience in radio communications, RF/antenna technology and/or network engineering, ideally in defence, rail or other mission-critical environments
-
Solid knowledge of RF design, antenna theory and radio protocols (e.g. VHF/UHF, Wi-Fi, 4G/5G)
-
Strong IP networking skills: routing and switching (e.g. OSPF, BGP, MPLS), VLANs, QoS and network virtualisation
-
Good understanding of cybersecurity in communication networks (firewalls, RADIUS/NAC, secure network architectures)
-
Experience with simulation tools such as CST, HFSS, MATLAB or comparable environments
-
Confident handling of RF measurement equipment (VNA, spectrum analyser, field strength measurement) and network analysis tools (e.g. Wireshark, iPerf)
-
Experience with military signals or tactical communication systems is a strong advantage
-
Analytical, structured way of working, strong problem-solving skills and a hands-on attitude in the lab and in the field
-
Team player with strong communication skills and willingness to travel to test and deployment sites
-
Very good English skills (written and spoken); German is a strong advantage
-
Eligibility to work in Switzerland (Swiss or EU citizenship required) and willingness to undergo a Swiss personnel security screening
