Ground Segment System Architect

**Who we are**:
Welcome to one of Europe’s most exciting New Space companies, creating the world's first fully connected mesh network in the sky. We are an international team of experts and engineers who have spent their careers expanding the boundaries and potential of space, now united in pursuit of a single vision. We value trust, open communication and collaboration to achieve the best results together.

Now we are looking for the best talents for our locations in Munich and Berlin to help us make our vision come true.

**Your mission**:
As **Ground Segment System Architect**, you will support the Ground Segment Lead Architect in designing, developing, and implementing the Ground Segment system for Rivada Space Networks. The Ground Segment is a core component of our satellite network, enabling seamless communication between the satellite constellation, user terminals, and network control systems.

In this role, you will contribute to the architecture and integration of various Ground Segment components, including network operations, RF resource management, SDN solutions, and OSS/BSS interfaces. You will be involved in the Model-Based System Engineering (**MBSE**) activities working regularly with the MBSE team and being responsible for the segment-level modelling activity aimed at capturing the Ground Segment functional design in the MBSE System Model.

You will be working closely with internal teams, external suppliers, and the Lead Architect, you will ensure the Ground Segment meets performance, reliability, and scalability requirements. You will also take ownership of managing system requirements, defining use cases, and overseeing interface development across all Ground Segment components.

**This includes**:

- Supporting the definition of Ground Segment system requirements, Interface Requirements and architecture in alignment with overall system specifications
- Managing system requirements, ensuring traceability, consistency, and compliance with technical and operational needs
- Defining and maintaining **use cases** to drive the development, validation, and optimization of Ground Segment functionality
- Overseeing the definition and management of **interfaces** between Ground Segment subsystems, including Network Control, RF resource management, user terminal interfaces, SDN solutions, OSS/BSS, and payload control systems
- Development of Model-Based System Engineering (**MBSE**) models with a focus on the ground segment design, functional analysis, functional allocation, interfaces and data modelling
- Contributing to the design and optimization of key Ground Segment components, ensuring seamless integration with the satellite constellation and user terminals
- Collaborating with the Lead Architect to ensure the interoperability of Ground Segment hardware and software components
- Working closely with suppliers to manage the development and delivery of Ground Segment components, ensuring they meet technical, quality, and timeline requirements
- Providing support to Ground Segment operations, enabling smooth transition from development to operational readiness
- Ensuring scalability and flexibility of the Ground Segment to meet evolving system needs and future technological advancements
- Collaborating with cross-functional teams, including RF, system engineering, and software development teams, to deliver an integrated, high-performance Ground Segment solution

**What you bring on the table**:

- University degree in Engineering, Telecommunications, Systems Engineering, or a related technical field
- ** Minimum 5 years** of experience in Ground Segment system design and architecture for satellite communication systems
- Proven experience in defining and managing **system requirements**, use cases, and technical interfaces
- Good understanding of satellite communications, including RF resource management, payload operation
- Proven experience in Model-based Systems Engineering methodologies and tools
- Preferably, practical experience with ARCADIA methodology and Capella tool
- Experience in the design and implementation of complex Ground Segment architectures, including network control, RF systems, and user terminal interfaces
- Familiarity with **SDN** (Software Defined Networking), network routing (e.g., MPLS, OSPF), and integration with OSS/BSS systems
- Knowledge of RF standards (e.g., DVB-S2X, beam hopping) and dynamic resource allocation concepts.
- Familiarity with systems engineering processes, methods, tools and standards
- Strong analytical and problem-solving skills, with the ability to perform trade-off analysis and feasibility assessments
- Excellent communication and teamwork skills, with the ability to collaborate effectively in cross-functional, international teams
- Fluency in written and spoken English
- A proactive mindset, with the ability to take ownership of technical challenges and deliver results in a fast-paced environment
