Principal Systems Engineer (E2E Technical Coordination)
Location: Portsmouth or Stevenage (minimum 3 days onsite)
Type: Permanent / Contract
Security Clearance: Eligible for UK Security Clearance
About the Role
KDC Projects is seeking an experienced Principal Systems Engineer to provide End-to-End (E2E) Technical Coordination across a complex system development programme. Working closely with the E2E Chief Engineer, you will be responsible for ensuring technical coherence across multiple subsystems, disciplines, and stakeholders, supporting the successful delivery of system engineering, validation, verification, and qualification activities.
This is a technically focused leadership role requiring strong systems engineering expertise, stakeholder management skills, and the ability to coordinate activities across the full system lifecycle. You will work within an established programme, maintaining and evolving existing system engineering artefacts rather than developing them from first principles.
Key Responsibilities
Systems Engineering
- Lead and coordinate end-to-end system engineering activities across multiple subsystems and work packages.
- Develop, maintain, and mature Concept of Operations (CONOPS) documentation.
- Manage user and mission requirements, including requirements derivation and flow-down.
- Maintain system engineering documentation and engineering management artefacts.
- Support the development and maturation of system and subsystem functional architectures.
- Coordinate performance, functional, and security requirement analysis.
- Ensure consistency across operational, functional, and non-functional requirements.
- Coordinate technical activities across internal teams, customers, and partner organisations.
