Associate Director - Fire Safety Engineering

Longer term, this role offers a strong pathway towards Technical Director and broader senior leadership opportunities. You will have the opportunity to build your profile through involvement in nationally significant infrastructure projects, challenging nuclear projects and multidisciplinary engineering environments, while shaping a career aligned to your technical interests and professional ambitions.

Core Capabilities

Fire Safety Engineering Expertise

You will bring extensive experience in fire safety engineering and a passion for solving complex technical challenges. Working across novel designs, high-hazard facilities and safety-critical environments, you will lead the development of fire safety strategies, undertake engineering assessments and provide expert technical guidance throughout project lifecycles.

This role offers the opportunity to apply advanced fire engineering principles, modelling techniques and engineering judgement to projects where innovative thinking is required. Your expertise will help ensure all solutions are practical, compliant, technically robust and aligned with client objectives. A strong understanding of UK fire legislation and guidance, including Approved Document B, BS 9999 and the PD 7974 framework, will be central to your success.

Regulator and Stakeholder Interaction

You will act as a trusted adviser to clients, regulators and project stakeholders, representing Tetra Tech in technical discussions and helping to navigate complex approval processes. Your ability to communicate technical concepts clearly, build strong professional relationships and balance competing priorities will be critical.

Alongside technical leadership, you will contribute to business development by identifying new opportunities, expanding client relationships and supporting the growth of key accounts. You will play an important role in maintaining long-term partnerships and ensuring clients receive a consistently high-quality service.

Technical Report Writing and Quality Assurance

You will lead the production, review and approval of high-quality fire engineering documentation, ensuring technical accuracy, clarity and consistency across all deliverables. This includes fire safety strategies, engineering assessments and specialist technical reports.

Your analytical approach and attention to detail will ensure complex engineering concepts are translated into clear recommendations that support effective decision-making. You will provide quality assurance across project outputs, maintaining the highest standards of technical excellence and regulatory compliance.

Proposals and Project Management

You will take ownership of projects from initial client engagement through to successful delivery, defining scopes of work, preparing fee proposals and providing strategic project direction. Working closely with clients and project teams, you will ensure projects are delivered efficiently, commercially and to the highest technical standards.

Success in this area will come from balancing technical leadership with strong commercial awareness, effective resource management and the ability to deliver multiple projects within agreed budgets, timescales and quality requirements.

Mentoring and Line Management

As a senior member of the team, you will play a key role in developing the next generation of fire engineering professionals. You will provide coaching, technical guidance and constructive feedback, helping colleagues build confidence, capability and expertise.

You will contribute to a collaborative and high-performing culture, supporting professional development, knowledge sharing and continuous improvement across the team. The role also offers the opportunity to take on line management responsibilities and influence the long-term development of the Fire Engineering function.

Training, Qualifications And Experience

You will hold a degree in Fire Engineering, Engineering, Science or a related technical discipline, or be able to demonstrate equivalent professional competence through experience. Significant experience in fire safety engineering is essential, including a proven track record of leading complex projects, managing technical delivery and working within regulated environments.

A strong understanding of fire engineering principles, methodologies, UK regulations and industry guidance is required, together with the ability to provide expert advice on complex engineering challenges.

Experience within the nuclear sector would be advantageous but is not essential. Applications are welcomed from professionals working within other highly regulated, technically complex or high-hazard industries. Chartered status with the Institution of Fire Engineers, or progress towards chartership, would be highly desirable.

Working Environment

This role offers a flexible hybrid working model designed to support both collaboration and individual productivity. Team members typically attend the office two to three days per week, with the remainder of their time worked remotely.

The Fire Engineering team is primarily based in Warrington, with additional office locations in West Cumbria and Basingstoke. Fully remote working would be considered.
