Principal Fire Engineer in City of London

Harmony is on a mission to be the best life safety partner to work with and for. Rated an ‘Outstanding Employer’ by Best Companies in 2025, we are only getting bigger and stronger — and we’re looking for A-players to help us get there. We are passionate about making a difference and obsessed with quality. Our goal is to build a world where every resident can sleep safely at night, knowing their home is 100% safe. Our Consultancy division is growing rapidly across London, and we are looking for a Principal Fire Engineer to serve as our technical authority — leading the most complex commissions, setting the standard for quality and methodology across the team, and playing a central role in shaping how Harmony’s fire engineering consultancy develops. This is a senior leadership role as much as a technical one. You will lead from the front on FRAEW and fire engineering commissions, mentor and develop junior and senior engineers, and work closely with the Head of Consultancy to drive business development and build the capability of the London team. If you are a highly experienced fire engineer who is ready to take on a role with real influence — this is it.

Key Responsibilities

• Serve as the technical authority for Harmony’s London Consultancy team — providing expert oversight, peer review, and sign-off on complex fire engineering assessments and FRAEW reports.
• Lead and deliver the most complex fire engineering commissions, including FRAEW assessments in accordance with PAS 9980, fire strategies, and specialist fire safety consultancy.
• Set and maintain the technical quality standard across the consultancy team — establishing methodology, reviewing outputs, and ensuring every report leaving the team is defensible and client-ready.
• Mentor, coach, and develop Senior and Junior Fire Engineers, supporting their technical progression and building a high-performing consultancy team.
• Act as a senior client-facing representative for Harmony — building and maintaining relationships at the highest level with housing associations, local authorities, developers, and managing agents.
• Support the Head of Consultancy with business development activity — identifying opportunities, contributing to bids and proposals, and attending client meetings and industry events.
• Monitor legislative and technical developments — including the Building Safety Act, PAS 9980, and related guidance — and ensure the team’s methodology evolves accordingly.
• Contribute to the development of Harmony’s consultancy processes, templates, and quality assurance frameworks.
• Represent Harmony externally at industry bodies, working groups, and professional forums as required.

Skills, Knowledge & Expertise

• An A-player mindset — high standards, extreme ownership and the drive to do things properly, the first time.
• Extensive experience in fire engineering consultancy, with a strong track record of leading complex commissions and producing defensible, high-quality outputs.
• Recognised technical authority in FRAEW assessments and PAS 9980, with substantial experience delivering these at scale across residential portfolios.
• Degree-level qualification in fire engineering, building surveying, or a related discipline.
• Chartered membership of a relevant professional body (IFE, RICS, CIOB or equivalent) — with a credible and respected profile in the industry.
• Proven experience leading, mentoring, and developing a team of fire engineers.
• Excellent technical writing and communication skills — able to produce and review complex outputs to the highest standard.
• Commercially aware — comfortable contributing to business development and representing Harmony at a senior client level.
• Deep working knowledge of the Building Safety Act, Fire Safety Act, PAS 9980, and wider fire safety legislation and guidance.
• EWS1 signatory status (or working towards it).

Nice to Have

• Experience working across large-scale social housing or residential high-rise portfolios.
• Knowledge of BS 9997 and wider fire risk management frameworks.
• RICS Level 6 EWS Diploma or equivalent advanced qualification.
