Job Description

We are looking for an experienced and innovative Environmental Testing & Degradation Mitigation (ETDM) Manager to lead a high-profile environmental qualification and degradation mitigation programme valued at approximately £6 million over three years. This strategic leadership role will play a pivotal part in ensuring that materials, components and systems can withstand the demanding environments encountered within a fusion power plant.

Working closely with the Fusion Partner (UKAEA), universities, research organisations and industrial partners, you will drive the generation of the environmental performance evidence needed to support design substantiation, regulatory compliance, inspection and maintenance strategies, and long-term plant reliability.

The Opportunity

As the recognised subject matter expert for environmental durability and degradation risks, you will sit at the intersection of materials science, reliability engineering, systems engineering and experimental validation.

You will lead multidisciplinary teams to develop environmental testing programmes, identify degradation mechanisms, assess risks to plant performance, and implement mitigation strategies that support the successful delivery of the STEP Prototype Plant and future commercial fusion facilities.

This role focuses on non-irradiated environmental degradation and qualification, working in close partnership with irradiation science and materials modelling teams to ensure a joined-up approach to materials qualification.

Key Responsibilities

Environmental Testing Strategy & Programme Leadership

• Develop and own the environmental testing and degradation qualification strategy for critical STEP systems, materials and components.
• Define testing roadmaps aligned with product development milestones, design maturity and regulatory requirements.
• Lead the planning, prioritisation and execution of component and system-level environmental test campaigns.
• Work closely with the Design Authority to ensure evidence generation supports key engineering and qualification decisions.

Degradation Assessment & Mitigation

• Lead investigations into degradation and failure mechanisms including:
  • Thermal fatigue and ratcheting
  • Creep and creep-fatigue interaction
  • Embrittlement
  • Corrosion, oxidation and stress corrosion cracking
  • Erosion and sputtering
  • Hydrogen and tritium-related effects
  • Electrical insulation ageing and breakdown
  • Seal, coating and joining degradation
• Develop practical mitigation strategies through:
  • Material selection and qualification
  • Surface engineering and coatings
  • Design improvements
  • Environmental controls
  • Inspection, maintenance and replacement planning
• Ensure test findings are translated into design requirements, materials databases and lifecycle models.

Programme Delivery & Resource Management

• Develop and maintain a long-term ETDM strategy aligned with programme objectives, timescales and funding profiles.
• Manage programme budgets and forecasts, ensuring delivery against technical, schedule and cost targets.
• Provide robust justification for future investment and resource requirements.
• Ensure all activities remain focused on supporting STEP materials qualification and design substantiation objectives.

Innovation & Economic Impact

• Foster a culture of technical excellence and innovation.
• Identify opportunities to apply novel qualification approaches beyond the fusion sector.
• Promote effective management of intellectual property, inventions and patents.
• Encourage publication and dissemination of research where appropriate.

Stakeholder Engagement & Reporting

• Build strong communication pathways across the STEP programme and wider stakeholder community.
• Present technical progress and strategic updates to senior leadership and programme boards.
• Contribute to technical reviews, advisory groups, business planning activities and government reporting.
• Represent the programme at conferences, industry forums and technical collaborations.

Leadership

• Create an inclusive, collaborative and high-performing team culture.
• Provide leadership across multidisciplinary technical teams and external partnerships.
• Champion organisational values and act as a role model for professional excellence.
• Make sound, risk-informed decisions that support programme success.
