Core Responsibilities

Primary Functions

Prepare instrument surfaces for coating by interpreting engineering drawings and job orders, performing thorough inspection, and planning the sequence of operations to ensure adherence to specifications and finish standards.
Perform surface cleaning and degreasing using approved solvents and aqueous cleaners, remove contamination, and document compliance with MSDS and hazardous material handling procedures.
Execute mechanical surface preparation techniques including sanding, abrasive blasting, chemical etching and hand finishing to achieve required surface profile and adhesion for primers and topcoats.
Mask and protect sensitive areas, connectors, labels and optical features using tape, plugs and custom fixtures to prevent overspray and maintain component functionality.
Mix, thin and prepare primers, sealers, topcoats and specialty finishes using manufacturer specifications, color formulas and digital tinting systems to achieve consistent color match and coating properties.
Apply coatings using spray equipment (HVLP, conventional, electrostatic, airless) following process control parameters — gun setup, nozzle selection, fan pattern, fluid pressure and distance — to meet film build and appearance requirements.
Operate and maintain paint booth equipment including filtration systems, downdraft/ crossflow booths, bake ovens and curing systems; monitor booth environmental controls (temperature, humidity, airflow) for process stability.
Apply powder coatings including pretreatment, masking, powder spray application and oven curing, and verify cure schedules with temperature monitoring and part sampling.
Conduct touch-up and hand-finishing operations using small spray guns, brushes and pens to repair chips, run-outs and assembly damage, ensuring visual and functional integrity with minimal rework.
Perform adhesion, dry film thickness (DFT), gloss, color and hardness tests, document results, and escalate nonconforming conditions to Quality/Engineering for disposition.
Maintain traceability and process records: job cards, batch tickets, lot numbers, curing times and inspection stamps to support audits, traceability and regulatory compliance.
Interpret and comply with coating specifications, customer special process requirements, and regulatory standards (FAA, EASA, ISO 9001, NADCAP where applicable) and participate in internal/external audits.
Troubleshoot coating defects such as orange peel, runs, fish eyes, blushing, delamination and poor adhesion by investigating root causes and implementing corrective actions to prevent recurrence.
Calibrate and maintain spray equipment, gauges and testing tools; perform routine preventive maintenance and coordinate repairs with maintenance teams to minimize downtime.
Collaborate with Manufacturing Engineering and Materials teams to qualify new coatings, revise processes, optimize cure cycles, and ensure cost-effective application methods while maintaining quality.
Train and mentor apprentices, new hires and cross-functional staff on best practices for surface preparation, application techniques, safety and finishing standards.
Ensure strict adherence to PPE, respiratory protection programs, hazardous waste disposal, and facility safety rules; participate in safety meetings and support 5S/lean continuous improvement efforts.
Coordinate with assembly, electro-mechanical and inspection teams to sequence work and support on-time delivery for kits and assemblies, including quick-turn and prototype builds.
Use computerized color matching tools, spectrophotometers and reference standards to ensure consistency on production runs and variant part numbers.
Prepare finished instruments for shipment by performing final inspection, packing to specification, and completing shipping documentation to preserve quality during transit.
Maintain clean, organized work areas and properly store paints, solvents and consumables to meet environmental and housekeeping standards.

Secondary Functions

Support process improvement projects by collecting data on cycle times, first-pass yield and rework rates and proposing process adjustments backed by metrics.
Assist Quality and Engineering teams with sample preparation for root cause analysis and participate in multi-disciplinary problem solving (8D, PDCA).
Provide input to procurement for preferred coating suppliers, masking materials and consumables based on shop experience to optimize cost and performance.
Participate in cross-training across finishing, assembly and maintenance areas to provide operational coverage and flexibility during peak demand.
Support rapid prototype and R&D painting needs for product development teams, including small-batch specialty finishes and experimental coatings.
