Job summary

UK Atomic Energy Authority is seeking a Senior Systems Engineer to own delivery across complex, multidisciplinary projects. You will translate stakeholder needs into requirements, architectures, interfaces, and verification plans, ensuring traceability and robust technical decisions.

You will work with a wide engineering team across systems and disciplines, mentoring colleagues and applying MBSE practices to drive safe, reliable fusion energy development.

Qualifications

• Strong knowledge and practical application of systems engineering methods across requirements, architecture, interfaces, lifecycle, integration, verification and validation.
• Experience owning or coordinating systems engineering outputs for a system, subsystem, demonstrator, test rig or comparable technical scope.
• Ability to apply systems thinking to complex and multidisciplinary engineering challenges.
• Experience using modelling, analysis and structured trade studies to support technical decision-making.
• Confidence working independently and exercising professional engineering judgement.
• Strong communication skills, with the ability to build alignment across engineering disciplines and stakeholders.
• Structured, evidence-based approach to problem-solving, technical risk and decision-making.
• Experience in complex, regulated, research or experimental environments with MBSE/digital engineering toolsets would be beneficial.

Responsibilities

• Own systems engineering delivery for an assigned technical scope, maintaining coherence across requirements, architecture, interfaces, integration and verification.
• Develop and manage requirements, traceability and systems engineering artefacts throughout the engineering lifecycle.
• Define system and subsystem architectures and contribute to technical trade-offs across performance, safety, cost, schedule and lifecycle requirements.
• Manage technical interfaces and support configuration and change-impact analysis.
• Plan and coordinate integration, verification and validation activities, ensuring evidence is complete and traceable.
• Apply modelling and analysis techniques to support design decisions, trade studies and verification activities.
• Identify and manage technical risks, assumptions and dependencies with clearly documented rationale.
• Communicate complex systems engineering issues to stakeholders to enable evidence-based decisions.
• Mentor less experienced engineers and contribute to the continued development of systems engineering practice.
