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
- London-based client sites
- 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?
- Senior, respected servicing position
- Complex, technically interesting systems
- Autonomy and trust on site
- Strong training and standards
- Long-term stability within a quality-driven environment
