Chief Engineer

The role

As Chief Engineer, you will be responsible for the technical vision, engineering governance and solution integrity of the FJCAST programme.

The FJCAST Chief Engineer is the senior technical authority responsible for assuring the delivery of a secure, interoperable, and data‑driven Joint Collective Training capability.

The role is accountable for integrating simulation, synthetic environments, operational systems, communications, and data services into a coherent training ecosystem that delivers measurable training outcomes, enhances operational readiness, and enables seamless interoperability across UK Defence, NATO, and coalition partners.

Key Responsibilities

• Provide engineering leadership and act as the Technical Authority across the FJCAST programme, ensuring alignment with programme objectives, technical strategy, operational outcomes, and customer mission requirements.
• Own the programme's technical architecture, engineering strategy, and roadmap, leading the development of open, modular, scalable, resilient, and secure architectures that enable integration across Defence, NATO, coalition, and partner training systems.
• Lead the engineering strategy for modelling, simulation, synthetic environments, and collective training capabilities, ensuring effective federation and integration of Live, Virtual and Constructive (LVC) training systems to support realistic and operationally relevant exercise delivery.
• Ensure technical solutions enable effective planning, design, delivery, execution, and evaluation of Tier 3 and Tier 4 collective training exercises across UK Defence, NATO, coalition partners, and multi‑domain operational environments.
• Serve as the primary technical decision‑maker across the partner ecosystem and stakeholder community, providing technical assurance, solution oversight, and engineering direction throughout the programme lifecycle.
• Establish and maintain robust engineering governance, assurance, risk management, compliance, configuration management, and technical review processes, ensuring adherence to Defence, NATO, security, and industry standards and regulatory requirements.
• Develop and sustain strong collaborative relationships with MOD, NATO, coalition partners, industry stakeholders, and senior technical leaders, supporting programme delivery and collaborative working principles across a multi‑organisational environment.
• Lead systems integration across simulation platforms, exercise management systems, command and control (C2) systems, communications networks, federated compute platforms, edge compute stacks, data services, operational CIS, and digital infrastructure, ensuring a coherent end‑to‑end training ecosystem.
• Govern simulation interoperability and information exchange standards, including HLA, DIS, and related Defence and NATO integration frameworks, ensuring seamless interoperability across joint, coalition, and multi‑domain environments.
• Lead the development and evolution of the programme's data architecture, ensuring training, exercise, operational, and simulation data are exploited as strategic assets to support readiness assessment, lessons identification, experimentation, performance evaluation, and future capability development.
• Champion the exploitation of training analytics, operational insights, and After‑Action Review (AAR) capabilities, enabling evidence‑based decision‑making, continuous improvement, force preparedness, and operational readiness.
• Ensure technical decisions support service continuity, resilience, availability, and operational readiness, maintaining effective service delivery throughout mobilisation, transition, steady‑state operations, and capability evolution.
• Drive innovation and continuous improvement across engineering practices, tools, and methodologies, exploiting emerging technologies including AI‑enabled training support, advanced analytics, digital engineering, synthetic environments, cloud technologies, and automation.
• Collaborate closely with Programme Director, customer representatives, and external partners to ensure coherent delivery, integration, assurance, and evolution of services, systems, processes, and technologies.
• Build engineering capability across the programme by mentoring technical teams, promoting knowledge transfer, and fostering a culture of engineering excellence, innovation, systems thinking, and professional development.
• Represent engineering interests at programme boards, design authorities, technical reviews, customer engagements, operational working groups, and senior stakeholder forums, acting as the senior engineering advocate for the FJCAST solution.

Essential Skills and Experience

• Demonstrable experience in a Chief Engineer, Technical Authority, Chief Architect, or senior engineering leadership role within complex, multi-disciplinary programmes.
• Strong systems engineering and systems integration background, with proven experience leading engineering activities across the full programme lifecycle from concept, assessment and design through delivery, transition, operation, and sustainment.
• Experience delivering complex, multi‑supplier programmes, ideally within Defence, government, or highly regulated environments, involving multiple stakeholders, subcontractors, and partner organisations.
• Deep understanding of Defence collective training, Synthetic Environments, Modelling & Simulation (M&S), and Live, Virtual and Constructive (LVC) training systems.
• Proven ability to develop and govern complex technical architectures supporting systems integration, modelling and simulation, distributed computing, data exploitation, operational CIS, and federated training environments.

Knowledge of microservices, containerisation, orchestration platforms, and modern software deployment architectures.

• Knowledge of IT infrastructure, data centre technologies, server and virtualisation platforms, distributed edge‑compute environments, networking, communications systems, cyber security, and secure operational environments.
• Strong understanding of engineering governance, technical assurance, quality management, configuration management, technology management, safety, security, and risk management frameworks.
• Experience with modern engineering and delivery methodologies, including SAFe, Agile, Dev Sec Ops, ITIL4, digital engineering, model‑based systems engineering (MBSE), or hybrid delivery approaches.
• Experience developing or governing data‑centric architectures, including data integration platforms, analytics environments, data lakes/lakehouses, and the exploitation of training and simulation data to support operational readiness and exercise outcomes.
• Demonstrable experience working with synthetic training environments, simulation platforms, exercise management systems, operational CIS, controlled compute environments, and data‑driven training ecosystems.
• Experience designing, delivering or governing distributed simulation infrastructures, federated training environments, server‑based platforms, and edge‑compute capabilities supporting collective training, experimentation, or operational rehearsal activities
• Experience integrating modelling and simulation systems, operational CIS, communications services, exercise management systems, and training support capabilities into coherent collective training solutions
