Job Description Your mission: As Systems Engineering Manager, you will lead the systems engineering capability for the STEP programme, ensuring the integration of plant-wide systems and delivery of a robust, cohesive design. You’ll drive the application of Model-Based Systems Engineering (MBSE) in a pioneering context, shaping how fusion powerplants are designed and delivered. Key Responsibilities As Systems Engineering Manager, you will play a pivotal role in delivering an integrated design for the STEP prototype fusion plant. You’ll lead the systems engineering capability within UKIFS, applying Model-Based Systems Engineering (MBSE) in a ground breaking context and ensuring robust, cohesive solutions across the programme. Lead System Design and Integration: Define and oversee the plant-level system architecture, ensuring seamless integration across all major systems and Integrated Product Teams (IPTs). Lead the decomposition and traceability of requirements from plant-level down to subsystem level, ensuring alignment with programme objectives. Manage interface definitions and resolve technical conflicts between subsystems to maintain design integrity. Facilitate and participate in technical design reviews and trade-off studies to evaluate alternative solutions and optimise system performance. Serve as the technical authority for system-level decisions, guiding integration and design resolution across the programme. Champion MBSE Strategy and Implementation: Develop and articulate a clear vision for MBSE application within the STEP programme, recognising the unique challenges of fusion plant design. Lead the development of system models and associated engineering deliverables for the whole plant and major systems. Drive organisational and technical change to embed MBSE across the engineering lifecycle. Promote MBSE adoption across all engineering teams, enabling consistent modelling practices and improved collaboration. Continuously improve MBSE capabilities, tools, and workflows to enhance engineering efficiency and quality. Manage the Systems Engineering Team: Provide line management and leadership for the Design Authority’s systems engineering team. Build and sustain a high-performing team with the skills and mindset needed to deliver complex systems integration. Support professional development through coaching, mentoring, and training. Ensure the team delivers high-quality system models and engineering outputs aligned with programme needs. Lead Systems Engineering Across STEP: Develop and implement a consistent systems engineering strategy across the entire STEP programme. Collaborate with the Head of Engineering Governance to align systems engineering practices with broader engineering standards. Lead the development of tools, processes, and procedures to support systems engineering delivery across all IPTs. Define and deliver a systems engineering training and development strategy to build capability across the organisation. Embody a Leadership Mindset: Demonstrate curiosity, creativity, and resilience in solving complex engineering challenges. Foster a positive, inclusive, and collaborative team culture aligned with UKIFS values. Act as a cultural ambassador, promoting professionalism, integrity, and ethical behaviour. Uphold the Seven Principles of Public Life in all aspects of your work. Make informed decisions that balance technical rigour with strategic programme goals. The above is not intended to be an exhaustive list of activities and you may be required to undertake other reasonable tasks or duties requested.
