Summary

Gemini AMPM is adding an experienced AOV specialist to its smoke control team: someone with real site time installing automatic opening vent and smoke ventilation systems, who can design a system as well as fit one, and who can help lead the engineers working alongside them.

The work is varied: new installs, upgrades, replacements of failed systems, commissioning and service, in residential blocks and commercial buildings across London and the South East.

The work:

- Installation of AOV and smoke ventilation systems: stair and lobby vents, smoke shafts, roof vents and louvres, actuators, control panels, manual control points and firefighter override switches

- Residential blocks and commercial buildings: common corridors, stair cores and lobbies in occupied buildings, alongside new-build and refurbishment projects

- Design: survey the building, specify the system and produce the layout for new installs, upgrades and like-for-like replacements, working to BS EN 12101, BS 9991, BS 9999 and Approved Document B

- Help lead the team on site: plan the work, set the standard, and bring on the fire alarm and ventilation engineers we are training into the discipline

- Commissioning and handover, with cause and effect to the fire alarm agreed in-house with our own fire alarm engineers

- Service, fault-finding and remedials on existing systems to BS 7346-8, with plain-English reports for the Responsible Person

What we offer: basic salary £38,000 to £50,000 depending on experience and tickets, plus paid overtime, a company van, the standard workplace pension and employee ownership. Gemini AMPM has installed and maintained fire and security systems across London and the South East since 1997, and has been owned by an Employee Ownership Trust since 2024. Training is paid, including manufacturer courses, and progression runs on the AMPM Academy ladder.
