An excellent opportunity for an experienced Field Service Engineer – Mobile Welfare Units to join a well-established company.
Job Type: Full-Time, Permanent
Salary: Competitive Salary, Depending on Experience.
Location: Watford – Home Based – Working in the Field.
About The Company:
They are a market leader in the repair and maintenance of towable and static cabins that keep site teams warm, fed and safe on construction, civils and events sites nationwide.
About The Role:
To attend, diagnose and repair mobile welfare cabins in the field — restoring generators, power, heating, water and waste systems to full working order, first-time wherever possible, while working safely and unsupervised at customer sites.
The role is van-based and mobile, covering breakdowns and warranty/service work across customer and hire-fleet sites. A large share of faults are diagnosed remotely (via unit telemetry) before attending, so the engineer must be comfortable interpreting remote data and arriving prepared.
What the Role Actually Deals With:
Generators / diesel engines - Oil pressure & oil-change faults, fuel systems, exhaust/DPF, alternator, AVR, governor, glow, E-stop, servicing. Engines: HATZ, Kubota, Lombardini, Perkins, Stephill (Boss L48/L70/L100 units). Plumbing, water & waste - Frozen/burst pipes, tanks, UV filters, water pumps, toilets, waste-level sensors, leaks. Electrical & power - 12/24V DC systems, Victron kit (inverters, Cerbo, MPPT/solar), fuses, relays, wiring looms, sockets, PIR lighting, "no power" / dead-console faults, electrical-test compliance. Diesel heaters - Parking/diesel heaters — glow-pin and fuel-pump failure, re-priming, rewiring, thermostats, frost-related no-heat. Batteries - Lithium battery diagnosis (100/200Ah), BMS behaviour, Victron charge settings, deep-discharge recovery, charge/hold faults. Telemetry / comms - Units not updating/communicating — SIM/modem, Cerbo, remote-monitoring diagnosis and SIM replacement. Towing & chassis - Lifting rams/pins, wheels-down locking, coupling, brakes, tyres — getting units mobile. Hydraulics - Power packs, rams, solenoids for raising/lowering units. Fabrication - Doors, door closers, hoods, structural repair. Solar - Panels and MPPT charge faults.
Roughly 1 in 5 reported faults turn out to be user error
- so customer education, clear on-site communication and honest reporting matter as much as the wrench work.
