UV Printing Technical Engineer — Production

SB eCommerce Solutions Pvt Ltd; New Delhi; On-site; INR 1,500,000 - 2,400,000; Full time

Job summary

SB eCommerce Solutions Pvt Ltd is seeking an experienced service/maintenance engineer for UV inkjet equipment. You will oversee daily operation of UV flatbed and cylindrical printers, optimize print parameters, and ensure repeatable part registration with jigs and fixtures.

A strong PM discipline and deep printhead know-how are essential. You will work on ink systems, curing energy, substrate adhesion, and collaborate with a color specialist to keep output consistent.

Qualifications

• 4+ years hands-on with UV inkjet printing equipment (flatbed/cylindrical).
• Real printhead-level competence: maintenance, alignment, clog diagnosis & recovery.
• Working knowledge of UV LED curing, ink chemistry and adhesion on varied substrates.
• Demonstrated preventive maintenance discipline with a reproducible PM regime.
• Systematic fault diagnosis across machine, ink, substrate, environment and file.
• RIP software familiarity: ONYX, Wasatch, Fiery, Caldera, ErgoSoft or OEM RIPs.
• Comfortable with mechanical and electrical maintenance at component level.
• Able to train operators and write documentation in actionable language.

Responsibilities

• Day-to-day running of UV printing equipment; optimize print parameters for throughput and quality.
• Design jig/fixtures to hold parts flat and ensure repeatable registration.
• Manage printhead health, calibration, and cleaning; monitor curing and adhesion outcomes.
• Maintain ink systems, including white ink handling and degassing as needed.
• Create and update SOPs; train operators across shifts; document processes clearly.
• Build a critical spares list; manage vendor relationships and service escalations.
• Log downtime with cause codes and report actionable improvements.

Job description

• Day-to-day running of UV flatbed and cylindrical/rotary printing equipment
• Print parameter optimisation — resolution, pass count, print speed, head height, curing settings — balanced against throughput and quality
• Jig and fixture design for holding parts flat, square and repeatable; part-to-print registration
• Cylindrical printing specifically: chuck setup and alignment, rotation synchronisation, handling tapered and non-uniform bottle profiles, maintaining head gap over a curved surface
• White ink and varnish layer management, including build strategy and cure between layers

Maintenance and uptime

• Own daily, weekly and monthly preventive maintenance and make it stick — nozzle checks, capping station and wiper condition, purging routines, encoder strip and rail cleaning, filter and damper changes, waste ink management
• Printhead health as a first-order priority: nozzle deviation, clog prevention and recovery, alignment and calibration, and knowing when a head is genuinely finished versus recoverable
• Ink system management — circulation, white ink settling, ink lines, degassing, filtration
• UV LED lamp condition and curing energy verification; identifying intensity degradation before it shows up as adhesion failure
• Diagnose and correct print defects — banding, nozzle dropout, misregistration, orange peel, incomplete cure, colour variation
• Root-cause recurring failures rather than repeatedly fixing them. A defect that comes back monthly hasn't been solved

Substrate, adhesion and curing

• Qualify new substrates: adhesion testing, primer selection, surface preparation and treatment
• Establish and document validated print recipes per substrate and per product
• Control environmental factors that quietly destroy quality — dust, temperature, humidity, static

Colour and RIP interface

• Manage RIP-side settings for the UV equipment and keep our machines in a calibrated state
• Work alongside our colour management specialist, who owns profile creation. You own machine condition; they own colour standards. Both of you are needed for output to be right, and the boundary should be treated as a collaboration rather than a handover

Spares, vendors and continuity

• Build and maintain a critical spares list with realistic lead times, and hold what needs holding. Printheads and long-lead items are where a small stock decision prevents weeks of stoppage
• Manage OEM and dealer relationships, AMC contracts and service escalation; hold vendors to response commitments
• Maintain a downtime log with cause codes, and report honestly on what's actually costing us hours

People and documentation

• Write SOPs an operator can follow without you present
• Train operators across shifts and verify they can actually do it, not just that they attended
• Deliberately transfer knowledge rather than accumulate it

What we're looking for

Must have

• 4+ years hands-on with UV inkjet printing equipment — flatbed, cylindrical, or both
• Real printhead-level competence: maintenance, alignment, clog diagnosis and recovery. This is the single most important technical requirement
• Working knowledge of UV LED curing, ink chemistry behaviour, and adhesion on varied substrates
• Demonstrated preventive maintenance discipline — you can describe a PM regime you built and sustained, not just one you were handed
• Systematic fault diagnosis. You isolate cause across machine, ink, substrate, environment and file rather than guessing
• RIP software familiarity — any of ONYX, Wasatch, Fiery, Caldera, ErgoSoft, or OEM RIPs such as RasterLink or VersaWorks
• Comfortable with mechanical and electrical maintenance at component level
• Able to train operators and write documentation in language they'll actually use

Good to have

• Specific experience on Mimaki UJF or JFX, Roland LEF or VersaUV, Mutoh, Epson, or comparable Chinese-built UV flatbeds
• Rotary and cylindrical printing — bottles, tumblers, mugs, drinkware
• Experience as a service engineer with an OEM or machine dealer — see the note below, we rate this highly
• Printing on plastics, coated substrates and metals; primer and surface treatment experience
• Colour management fundamentals — linearisation, ink limiting, profile behaviour
• Jig and fixture design; basic CAD
• Screen printing, pad printing or sublimation exposure

A note on background: engineers who have worked for a UV machine OEM or dealer are strongly encouraged to apply. Servicing many machines across many customers builds a diagnostic range that's hard to acquire running one or two machines in one plant, and it's exactly the experience that prevents stoppages here.
