Key Responsibilities:
Architecture & Design
• Own and manage the end-to-end systems engineering process for assigned projects.
• Lead requirements capture, analysis, allocation, and management across subsystems.
• Drive the system through formal design gates including SRR, PDR, CDR, FAT, SAT
• Ensure traceability of requirements throughout the lifecycle and compliance with project and customer standards.
System Development & Integration
• Develop system-level architectures and interface definitions for satellite communications networks, ground systems, and mission-critical infrastructures.
• Perform system modelling, trade studies, and design analyses to inform architecture choices.
• Support integration, verification, validation, and transition-to-operations activities.
• Act as a technical authority, mentoring junior engineers and contributing to technical review boards.
Technical Leadership
• Work with multidisciplinary teams (network engineers, software developers, mission operators) to ensure cohesive technical delivery.
• Engage with commercial and defence customers to capture needs, present solutions, and gain buy-in at formal reviews.
• Contribute to bids and proposals by defining engineering approaches, resource estimates, and technical content.
Security & Compliance
• Support role-based access control (RBAC), secure file handling, and communication into the system architecture.
• Ensure compliance with aerospace security frameworks and OneWeb/CGI enterprise security policies.
Project & Stakeholder Management
• Work with multidisciplinary teams (network engineers, software developers, mission operators) to ensure cohesive technical delivery.
• Engage with commercial and defence customers to capture needs, present solutions, and gain buy-in at formal reviews.

Required qualifications to be successful in this role:
Essential:
• Bachelor’s degree in Systems Engineering, Aerospace Engineering, Electrical Engineering, or a related discipline.
• Minimum 5 years of experience in the space, SATCOM, or defence sector.
• Demonstrated expertise in systems engineering across the full lifecycle, including:
• Strong knowledge of satellite communications systems (space and ground segments), architectures, and operations.
• Excellent communication skills with the ability to interact confidently with stakeholders at all levels.
• Requirements management (DOORS, Jama, or equivalent).
• Design reviews (SRR, PDR, CDR).
• Verification and validation (FAT, SAT, integration testing).
Desirable:
• Master’s degree in Systems Engineering, Aerospace, or Defence-related discipline.
• Chartered Engineer (CEng) status or working towards it.
• Familiarity with model-based systems engineering (MBSE) tools and approaches (SysML, Cameo, Capella).
• Experience working on both commercial satellite programmes and MoD/defence projects.
• Knowledge of mission assurance, safety, and reliability engineering in aerospace.
