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:

Bourne, Lincolnshire  Depot Based.

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 (100/200

Ah), 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.
