Job description

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.

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.

Candidate Requirements

Essential:

• Proven multi-skilled field service / plant / mobile-mechanic background (welfare units, generators, plant, HGV, marine, motorhome/leisure, or similar).
• Diesel engine fault-finding and servicing (small industrial engines — HATZ, Kubota, Lombardini, Perkins or equivalent).
• 12V / 24V DC electrical competence — fault-finding wiring, fuses, relays, inverters, charging systems using a multimeter.
• Confident reading fault data / telemetry and working from remote diagnostics.
• Practical plumbing / water-system repair skills.
• Strong problem-solving and first-time-fix mindset; comfortable working alone and unsupervised.
• Full UK driving licence; B+E (trailer/towing) entitlement or willingness to obtain.
• Good customer-facing manner and clear written job reporting.

Highly Desirable:

• Electrical qualification — City & Guilds 2391 (Inspection & Testing) and/or 18th Edition (BS 7671); PAT competence.
• Experience with Victron energy systems (Cerbo GX, MultiPlus inverters, MPPT, VRM) and lithium/BMS battery systems.
• Diesel parking/air heater experience (Webasto/Eberspächer-type).
• Hydraulics (power packs, rams, solenoids).
• Fabrication repairs.
• Solar PV, and basic IT/comms (SIM, modem, routers) familiarity.
• Relevant safety tickets (CSCS Card, first aid, working at height, manual handling).

Personal Attributes

• Self-motivated and reliable — the customer's day-rate is stopped until the unit works again.
• Methodical and safety-first, especially around live electrics, fuel and lifting operations.
• Resilient and adaptable — outdoor, all-weather, sometimes remote sites.
• Honest reporter — records what was found and done, including when a fault is user error or unresolved.

Working Conditions

• Field-based, mobile role with company van and tools.
• Regional travel to customer and hire sites; some early starts / site-hours working.
• Breakdown-response element — may include on-call / out-of-hours cover (to be confirmed).
• Physical role: lifting, working outdoors, in confined welfare-unit plant spaces and all weathers.

What they offer

• Competitive salary (depending on experience).
• Company pension.
• Company van, tools and PPE.
• Manufacturer and in-house training across generators, power, heating and telemetry.
• Varied, hands-on work with a UK manufacturer that builds what you fix.
