Field Service Engineer - Tactical Communications
Confirmed on the employer's own hiring board on Oct 12, 2026. First seen by Alion on Sep 24, 2026.
About Us
Kägwerks, a Codan company, develops advanced tactical communications and networking technology for defence, government and national security customers.
We specialise in mobile ad hoc networking (MANET), edge computing and integrated C5ISR solutions designed to operate in disconnected, degraded, intermittent and bandwidth-limited environments.
Kägwerks is growing rapidly within the MANET market, creating opportunities to work on a wide variety of specialist projects with military teams, government customers and technology partners.
About The Role
The Field Service Representative (FSR) is a key member of the Kagwerks Rest of World organisation and is responsible for providing highly capable technical, operational, and customer-facing support for the deployment, integration, demonstration, and sustainment of advanced Kagwerks systems.
The role requires a strong understanding of tactical communications, Mobile Ad Hoc Networks (MANET), IP networking, edge computing, and AI/ML-enabled technologies. Working directly with military, government, and specialist end users, the FSR will support systems throughout the customer lifecycle, from initial capability demonstrations and trials through to deployment, training, operational support, and ongoing system optimisation.
The successful candidate will be comfortable operating independently in challenging and potentially austere environments and will be capable of translating complex technical capabilities into practical operational solutions.
You Will
- Integrate tactical radios, Software Defined Radios (SDRs), edge compute platforms, sensors, applications, and other C5ISR components.
- Support the integration and deployment of AI/ML-enabled products operating at the tactical edge.
- Conduct technical demonstrations, customer evaluations, field trials, and Proof of Concept activities.
- Deliver operator and technical training to military, government, partner, and reseller personnel.
- Diagnose and resolve hardware, software, network, and system integration issues in field environments.
- Conduct network planning, system configuration, fault finding, and performance optimisation.
- Support tactical data distribution across RF and IP networks.
- Work closely with Systems Engineering and Product teams to identify, investigate, and resolve technical issues.
- Capture end-user feedback and translate operational requirements into practical technical recommendations.
- Produce technical reports, configuration documentation, test reports, and After-Action Reviews (AARs).
- Provide technical support to Business Development and Sales teams during customer engagements, exhibitions, demonstrations, and trials.
- Maintain an excellent understanding of company products, competitor capabilities, and emerging C5ISR technologies.
- Provide deployed technical support internationally as required.
What We Are Looking For
The most important requirement is practical experience of MANET technology and tactical radio systems. You may currently work for a MANET, tactical communications or defence technology company, or have gained directly relevant experience within the Armed Forces.
You Should Also Have
- Proven experience in tactical communications, C5ISR, military communications, field service engineering, or systems integration.
- Strong practical experience with MANET, mesh networking, tactical radios, SDRs, and RF communications.
- Strong knowledge of IP networking, including IPv4/IPv6, subnetting, routing, switching, VLANs, multicast, DHCP, DNS, and QoS.
- Experience integrating radios, edge compute platforms, sensors, applications, and other C5ISR systems.
- Experience supporting tactical edge computing and AI/ML-enabled technologies.
- Experience supporting military, government, or specialist end users in field, training, trial, or operational environments.
- Familiarity with TAK/ATAK or similar tactical situational-awareness systems.
- Understanding of cybersecurity principles relevant to deployed networks.
- Experience with SATCOM, LTE/5G, Wi-Fi, ISR sensors, video, or telemetry is desirable.
- Previous military experience within Signals, Communications, C5ISR, Intelligence, Special Operations, or a related technical discipline is highly desirable.
Technical Competencies
- MANET, tactical radio, SDR, mesh networking, and RF communications.
- TCP/IP networking, IPv4/IPv6, routing, switching, VLANs, multicast, DHCP, DNS, and QoS.
- Network planning, configuration, fault finding, diagnostics, and performance optimisation.
- Linux and/or Windows operating environments.
- Integration of radios, compute, sensors, applications, and tactical data systems.
- Tactical edge computing and AI/ML deployment in bandwidth- and resource-constrained environments.
- TAK/ATAK or equivalent tactical situational-awareness systems.
- Cybersecurity principles for deployed and tactical networks.
- Ability to translate complex technical capabilities into practical operational solutions.
- Technical documentation, system configuration, testing, and reporting.
Why Join Kägwerks?
This is an opportunity to join a rapidly growing business operating at the forefront of tactical networking and edge technology.
You will work on varied and technically challenging projects rather than supporting a single fixed product or programme. The role offers exposure to emerging communications technology, specialist military users and complex integration challenges where the quality of the solution has a genuine operational impact.
You will also have the opportunity to work across Kägwerks, DTC and the wider Codan group, collaborating with specialists in MANET communications, RF, embedded systems, edge computing and C5ISR.
Additional Requirements
- You must be willing and able to undergo UK Security Clearance
- You must be able to undertake regular UK and international travel, including occasional travel at short notice
- You must be able to meet relevant customer, security and international travel requirements
