Principal Fire Engineer

Are you excited by the idea of shaping fire safety solutions for next generation nuclear and energy facilities across the UK?

Have you experience developing fire safety strategies aligned to UK Building Regulations and recognised fire safety legislation?

Have you previously undertaken fire modelling using empirical calculations or tools such as CFAST or CFD?

The Opportunity

This opportunity has arisen due to significant growth within a major UK energy and nuclear engineering organisation, which is entering an exciting phase of opportunity by supporting our key client's UK nuclear fleet through a business transformation, and by supporting new small modular reactor developers. You'll join a highly skilled fire engineering team working across new build, generation, life extension, and defueling projects. The environment is supportive, flexible, and people-centred, with strong benefits including free single medical cover, enhanced parental leave, and reimbursement towards relevant professional development and memberships. This role is ideal for someone who enjoys technical depth, autonomy, and the chance to influence safety strategy across nationally significant infrastructure.

Your duties and responsibilities will be:

• Developing fire safety strategies to ensure compliance with Building Regulations and relevant fire safety legislation, including solutions for escape, detection and alarm, structural fire protection, suppression, and firefighting access/facilities. This is completed using both prescriptive guidance and fire engineering principles.
• Undertaking conventional fire assessments and fire risk assessments to support compliance and demonstrate ALARP where non-compliances exist.
• Carrying out fire modelling using empirical hand calculations and software such as CFAST and/or Computational Fluid Dynamics to support performance-based fire strategies.

Qualifications & experience

• Fire safety engineering experience covering most of the responsibilities listed above.
• Experience applying relevant prescriptive codes (e.g., ADB, BS 9999).

Additional desirable qualifications

• STEM degree (desirable, not essential).
• Membership with a recognised institution (e.g., Institution of Fire Engineers).
• Experience undertaking fire modelling to support performance-based engineered solutions.

The setting for the role

You’ll be based at one of several UK energy offices — including Newcastle, Glasgow, Warrington, Gloucester, Bristol or Knutsford — within a flexible hybrid working environment. The organisation places people at the heart of its culture, valuing safety, integrity, inclusion and diversity and fostering a strong sense of belonging and support for all employees.
