I’m recruiting for a Senior Service & Maintenance Engineer to support a well-established, high-quality electronic security integrator operating across commercial and construction environments in London.
This role is ideal for an experienced engineer who enjoys complex fault finding, taking ownership of live systems, and being trusted as the senior technical point on site. You’ll be responsible for keeping critical fire and security systems operational, compliant and reliable, while acting as a calm, professional presence with clients.
This is a hands-on senior role with no people management — focused on technical excellence, autonomy and long-term system performance.
The Role
As a Senior Service & Maintenance Engineer, you’ll take ownership of both planned preventative maintenance and complex reactive faults across a varied client portfolio.
You’ll be trusted to investigate issues thoroughly, identify root causes, carry out effective repairs and recommend sensible remedial or upgrade solutions where required.
Your day-to-day will include:
Planned preventative maintenance across fire & security systems
Diagnosing and resolving complex or recurring faults
Servicing live systems including CCTV, Access Control, Intruder and Fire Alarms
Root-cause analysis to reduce repeat call-outs and downtime
Repair, replacement and recommissioning of equipment
Producing accurate, audit-ready service documentation
Acting as a senior, client-facing technical representative
Advising clients on system condition, risks and next steps
Supporting installation and commissioning teams where servicing expertise is required
Participating in an on-call rota as an escalation-level engineer
This role plays a key part in maintaining system integrity, client confidence and long-term service relationships.
Technical Scope
CCTV, Access Control, Intruder and Fire Detection systems
Preventative maintenance, diagnostics, repair and recommissioning
Legacy and modern platforms
IP-based environments including networking fundamentals
Live, operational sites where accuracy and reliability are critical
Location & Travel

Role designed around public transport travel
Monthly travel costs covered (Zones 1–2)
No company vehicle required
What They’re Looking For
Minimum 5 years’ experience servicing electronic security systems
Strong fault-finding and diagnostic capability
Solid knowledge of CCTV, Access Control, Intruder and Fire systems
Familiarity with BS5839, BS7671 and industry codes of practice
Confident, professional client-facing communication
Ability to manage workload and priorities independently
Strong commitment to health & safety
Ability to pass background vetting / BPSS or SC clearance
Desirable but not essential:
IP networking knowledge
Level 3 (or higher) electrical/electronic qualification
ECS / CSCS card
FIA modules or fire systems training
Manufacturer training (e.g. Paxton, Avigilon, Gallagher, Salto, Texecom, Hikvision)
Salary & Package
£46,000 – £50,000 basic salary
Paid on-call rota
Monthly travel costs covered
Company phone, tools, uniform and PPE
Fully funded, role-relevant training and certifications
Employee ownership scheme (after qualifying period)
20 days holiday plus bank holidays
Why This Role?
