Core Responsibilities

Primary Functions

Operate, monitor and control bulk blending systems and equipment (batch and continuous blenders, ribbon mixers, pugmills, hoppers, conveyors, augers and pneumatic transfer systems) to produce consistent, specification-compliant product batches according to formulas and production schedules.
Accurately weigh, measure and load raw materials and additives using scales, load cells and feeders; verify material identity against bills of materials, labels and MSDS before each loading operation.
Execute production orders and batching instructions from the Manufacturing Execution System (MES) or PLC/HMI, selecting correct formulas, verifying batch sizes, and initiating automated/semiautomated blend cycles.
Prepare and maintain complete batch records, lot traceability logs and production documentation to meet internal SOPs and regulatory/audit requirements; ensure all readings, adjustments and out-of-spec events are fully documented.
Perform in-process quality checks, collect and label representative samples, follow sampling protocols, and coordinate with the laboratory for timely analysis (particle size, moisture, nutrient concentrations, pH, bulk density).
Calibrate and verify scales, flow meters and feed devices on a scheduled basis; report and escalate calibration discrepancies and ensure measurement accuracy for product consistency.
Adjust feed rates, agitator speeds, flow control valves and feeder settings to maintain blend homogeneity and meet target specifications while minimizing waste and rework.
Conduct pre-startup inspections, check safety interlocks, emergency stop systems, guards and sensors, and confirm materials and work areas are safe and ready prior to production.
Follow written SOPs, hazard communication (HAZCOM) and MSDS instructions for handling, storage and transfer of hazardous or regulated materials; use appropriate PPE and apply confined space and lockout/tagout (LOTO) procedures when required.
Load and unload bulk materials using forklifts or front-end loaders, coordinate with receiving and warehouse teams to reconcile delivered materials, inspect incoming materials for quality and shortages, and report discrepancies.
Monitor product flow and equipment performance to detect abnormal noise, vibration, temperature or material behavior; perform first-line troubleshooting and minor mechanical adjustments to maintain uptime.
Perform routine preventative maintenance tasks (cleaning screens, replacing seals, greasing bearings, clearing chutes and augers) and document work; coordinate with maintenance for complex repairs or parts replacement.
Manage packaging and bulk loading operations for outbound product (super-sacks, tote bags, pneumatic load-out, railcars/truck bulk loading), ensuring correct labeling, shipping documentation and lot integrity.
Implement and maintain good housekeeping practices in the blending area, including dust control, spill prevention, and proper disposal of waste materials to reduce contamination and maintain a safe work environment.
Respond to production deviations and non-conformances by quarantining affected product, initiating containment procedures, and communicating with quality and supervision to determine corrective actions.
Participate in continuous improvement initiatives, including kaizen events, 5S, root cause analysis and waste reduction projects to increase efficiency, yield and product quality.
Train new operators and cross-train within blending and adjacent production processes; develop and follow training checklists and competency assessments.
Support environmental and safety reporting by documenting emissions controls, spill incidents, and corrective actions; assist in regulatory inspections and internal audits as requested.
Operate PLCs, HMIs and basic computerized control systems to start/stop processes, change recipes, monitor alarms and generate production reports; escalate complex control issues to automation specialists.
Ensure compliance with site-specific policies, OSHA standards, DOT and local environmental regulations related to dust management, chemical handling and transportation of hazardous materials.
Coordinate with procurement and inventory teams on material shortages, reorder levels, lot rotations and cycle counting to avoid production interruptions and ensure FIFO practices.
Maintain strong communication with shift handoffs, preparing accurate shift logs, highlighting unresolved issues and ensuring continuity of operations across teams and shifts.

Secondary Functions

Support continuous improvement and data collection activities by logging process parameters and production KPIs for trending and analysis.
Assist the quality lab in method validation, sample scheduling and stability testing when requested.
Participate in safety committees, risk assessments and incident investigations to help develop preventative action plans.
Provide input for SOP revisions, work instructions and process change requests based on frontline observations and process data.
Help coordinate contractor access and oversight for third-party maintenance or calibration services.
Assist logistics with scheduling bulk load-outs, coordinating truck/rail access and verifying shipping documentation as needed.
Support seasonal or campaign production planning by recommending optimal blend sequencing to minimize cross-contamination and changeover time.
