* Capture, analyse, and manage user, system, and sub‑system requirements
* Translate operational and mission needs into coherent system architectures
* Support mission system design, integration, and verification activities
* Define and manage interfaces between software, hardware, sensors, networks, and platforms
* Produce and maintain systems engineering artefacts (CONOPS, requirements, architectures, ICDs)
* Support integration, test, verification, validation (IV&V) and acceptance activities
* Work closely with software, hardware, safety, security, and operational stakeholders
* Support delivery planning, technical risk management, and trade‑off analysis
* Ensure compliance with security, safety, and regulatory standards
Essential Skills & Experience
* Proven experience as a Systems Engineer on mission systems
* Strong understanding of systems engineering lifecycle (V‑Model or equivalent)
* Experience capturing and managing requirements (system, sub‑system, interface)
* Experience producing system architectures and design artefacts
* Experience supporting system integration and verification
* Ability to work across software, hardware, communications, and operational domains
* Strong analytical, problem‑solving, and stakeholder communication skills
* Experience working in secure or regulated environments
* SC clearance or eligibility to obtain it
Mission Systems Experience (One or More)
* Defence, aerospace, policing, intelligence, or security mission systems
* Command & Control (C2), ISR, situational awareness, or surveillance systems
* Autonomous, semi‑autonomous, or decision‑support systems
* Sensor fusion, data integration, or real‑time operational systems
* Platform‑based systems (air, land, maritime, or space)
* Safety‑ or security‑critical operational systems
Desirable Skills & Experience
* Model‑Based Systems Engineering (MBSE) experience
* SysML, UML, or similar modelling approaches
* Experience with AI‑enabled or data‑driven mission systems
* Understanding of secure architectures and cyber considerations
* Experience with Agile or hybrid delivery models
* Familiarity with standards such as ISO/IEC/IEEE 15288
* Experience supporting bids, technical governance, or assurance activities
* Exposure to cloud, edge, or distributed mission systems
Why Join?
* Permanent role working on long‑term, high‑impact mission systems
* Opportunity to influence system design and operational outcomes
* Work alongside experienced engineers on complex, meaningful programmes
* Clear progression into Senior, Lead, or Chief Systems Engineer roles
* Competitive salary and benefits
* Support for clearance, training, and professional development
