In this position, you’ll work closely with internal engineers, architects, product and business development managers, and external suppliers leading the development of system components. You will write technical requirements, perform system trade studies, define the concept of operations, and maintain the technical baseline, including all the interface definitions. You will work closely with the program and the Integration & Test team to ensure that the system is developed and is fit for purpose.  This is a unique opportunity to make a significant impact within an organization that values growth, teamwork, and professional development.

Who You Are:

• You’re a system engineer who’s architected and followed the deployment and refinement of at least one large multi-user, bi-directional wireless communications system. This doesn’t have to be a satellite-based system.

• You have a deep understanding and experience in the system development, integration, verification, and validation process.  
• Possess 10-15 years of industry work experience

What You’ll Do:

• Define the functional composition of the whole communications system – which subsystem are going to perform various tasks and processes.
• Define and implement processes for making and tracking key architectural decisions and changes.
• Own the system level requirements and work with subsystem leads to ensure their requirements reflect the system needs.
• Maintain the technical baseline and lead the Integrated Product Team initiatives
• Perform system trade-studies
• Define CONOPS to ensure that the system functional flows are clearly defined
• Maintain the key sub-system level interface documentation and associated schema
• Work with subsystem suppliers to ensure their designs meet the system level needs.

What You’ll Need:

As well as systems engineering experience, you should have deep expertise and prior experience working in at least one of the following specific areas:

• 3GPP (5G) end to end system architecture
• Radio Access Network design/customization and implementation/deployment
• Air Interface implementation/modelling/customization
• Satellite User Terminal design and architecture

You also should have experience of using various systems engineering software tools for requirements management and model-based systems engineering.
