About the Company
Our client is a leading European space and aerospace technology group developing advanced satellite systems, ground infrastructure, and mission-critical technologies for institutional, commercial, and defence customers.

The company contributes to major European and international space programs across satellite platforms, communications systems, ground stations, Earth observation, exploration, and secure space infrastructure .

Its engineering teams work on technically demanding missions where RF performance, system reliability, precise integration, and successful in-orbit operations are critical.

The Role
We are looking for a Subsystem Engineer – Satellite Communications Systems to join a specialist communications engineering team in Germany.

In this role, you will take technical responsibility for key elements of the satellite communications subsystem , including Telemetry, Tracking & Command (TT&C;) and Payload Data Downlink .

You will contribute to the definition, design, development, and verification of communication architectures across the full project lifecycle — from early system design and supplier coordination through Assembly, Integration and Test (AIT), satellite testing, Launch and Early Orbit Phase (LEOP), and In-Orbit Testing (IOT) .

Working with internal engineering teams, customers, suppliers, and international partners, you will help ensure that complex satellite communication systems meet demanding technical and operational requirements.

Your Responsibilities

Take technical responsibility for satellite communication subsystems , including TT&C; and Payload Data Downlink

Define, design, and develop communication system architectures according to system, integration, verification, and testing requirements

Perform and coordinate technical analyses, including RF link budgets, performance assessments, and interface analyses





Design and review reflector antenna systems and complex satellite communication architectures

Design, simulate, and support laboratory implementation of complex RF transmit and receive chains

Prepare and maintain system specifications, subsystem requirements, and technical documentation

Coordinate technical activities with project teams, customers, partners, suppliers, and other stakeholders

Provide technical management and oversight of suppliers and subcontractors responsible for subsystem equipment and components

Collaborate with external partners on component selection and new technology developments

Support Assembly, Integration and Test (AIT) activities at subsystem and system level

Participate in commissioning and testing activities at facilities and ground stations worldwide

Support satellite testing, LEOP activities, and In-Orbit Testing

Review system designs related to satellite communications

Support system automation as well as electrical design and commissioning activities together with specialist engineering teams

Contribute technical expertise to proposals, feasibility studies, and technology development activities

Your Profile

Completed degree in Electrical Engineering, Telecommunications Engineering, Communications Engineering, RF Engineering , or a comparable technical discipline

Initial professional engineering experience is required, ideally within the space or aerospace sector

Strong understanding of satellite communications, telecommunications, or RF/high-frequency engineering

Experience with RF measurement equipment and high-frequency measurement techniques





Ability to understand and work with complex communication architectures and technical interfaces

Experience with scripting or engineering tools such as MATLAB and/or Python is desirable

Experience interpreting electrical circuit diagrams and schematics is an advantage

Structured and analytical way of working combined with a practical, hands-on engineering mindset

Ability to independently manage priorities and responsibilities during periods of high workload

Confident and professional approach to technical discussions and conflict situations

Proactive communication style and willingness to take ownership of technical topics

Strong team-working skills and interest in working within a multicultural engineering environment

German language skills are an advantage but not mandatory

Willingness to travel internationally for commissioning activities, satellite testing, and ground-station testing

What’s Offered

Opportunity to work on advanced European and international satellite programs , including both commercial and security-related projects

Technical ownership of critical satellite communication subsystems

Exposure to the complete satellite lifecycle, from system architecture and RF design through integration, testing, launch, and early-orbit operations

Hands-on work with antennas, RF communication chains, satellite test environments, and ground stations

Collaboration with experienced multidisciplinary and multicultural engineering teams

Opportunity to work directly with international customers, partners, suppliers, and subcontractors

International travel typically around 1–2 times per year , depending on project requirements

Hybrid working model with up to approximately 40% home office

Long-term career opportunities within a highly technical European space environment

Please note that due to the nature of certain projects, a security clearance/background screening may be required
