Core Responsibilities

Primary Functions

Operate jar filling machines (gravity, piston, auger, or volumetric) to consistently achieve specified fill volumes and target piece rates while minimizing product giveaway.
Set up and changeover filling and capping lines, including tooling, nozzles, starwheels, and guides, to accommodate different jar sizes and product viscosities according to job orders and SOPs.
Calibrate and verify fill weights and volumes using scales and checkweighers, document results, and adjust machine settings to maintain accuracy and compliance with production specifications.
Monitor and control capping equipment (twist, torque, induction sealers) to ensure proper cap placement, torque specification, and seal integrity, rejecting and documenting defective closures.
Conduct in-line quality inspections for fill level, seal integrity, label placement, lid alignment and product appearance; quarantine off-spec product and complete corrective action paperwork.
Load and unload raw materials and packaging components (jars, lids, labels, cartons) and stage them to the line following FIFO and material handling best practices.
Follow GMP, HACCP, allergen control, and sanitation procedures continually, including wearing required PPE and maintaining clean work zones to prevent contamination.
Perform routine machine cleaning (CIP or manual wipe-down), sanitation, and end-of-shift breakdowns in accordance with sanitation schedules and written procedures to meet food safety standards.
Execute preventive maintenance tasks such as lubrication, belt and seal inspection, sensor cleaning, and basic mechanical adjustments to reduce downtime and extend equipment life.
Troubleshoot common mechanical, pneumatic, and electrical issues on filling and packaging equipment and work with maintenance or engineers for complex repairs.
Record production data accurately in logs, electronic systems, or batch records including run times, rejects, downtime reasons, shift handovers, and fill weight checks.
Adhere to all safety rules and plant environmental policies, participate in lockout/tagout procedures for repairs, and report hazards, near misses, and incidents promptly.
Maintain accurate batch and lot traceability by labeling production runs, logging lot codes, and ensuring proper segregation of samples for QC testing when requested.
Load and operate checkweighers, metal detectors, and vision systems; respond to equipment alarms, adjust settings, and coordinate with quality assurance to resolve detection issues.
Collaborate with QA/QC to pull product samples, complete sampling documentation, and support micro and chemical testing requirements when necessary.
Meet productivity targets while minimizing rejects and rework, practicing continuous improvement by suggesting process changes to improve yield, ergonomics, or cycle times.
Train and mentor new operators on standardized work, safety procedures, machine operation, and quality expectations to build team capability.
Execute changeovers quickly and efficiently while following documented checklists to minimize downtime and ensure consistent product output.
Ensure accurate labeling, date coding, and lot sequencing on finished jars and cases to meet customer and regulatory requirements.
Participate in daily production meetings, line audits, and safety stand-downs, providing feedback on line performance and improvement opportunities.
Coordinate with warehouse and logistics to stage finished goods, palletize outputs, and prepare product for shipment while maintaining accurate counts and paperwork.
Maintain housekeeping around the line—remove debris and packaging waste promptly and keep aisles clear to support a safe, organized workplace.

Secondary Functions

Support continuous improvement initiatives (5S, Kaizen) to optimize line flow, reduce waste, and improve ergonomics on the filling line.
Assist in data collection for OEE, downtime tracking, and yield reporting to support production analytics and management decisions.
Cross-train on upstream and downstream packaging stations (labeler, case packer, shrink wrapper) to provide flexible support during high-demand periods.
Help coordinate minor parts ordering and spare parts inventory for frequently serviced components to minimize changeover delays.
Participate in new product trials and scale-up activities, offering operator feedback to engineering and R&D on machineability and process robustness.
Support environmental health and safety audits and corrective action follow-up to ensure regulatory compliance.
Complete batch documentation and electronic entry of production records to support traceability and internal/external audits.
Act as liaison to maintenance and engineering during root cause analyses for repeated equipment failures or quality escapes.
