Emerging
Entry / Apprentice
  1. Specified amounts of refined or unrefined materials — dump, pour, or load into equipment or containers under direct supervisor guidance on the production floor.
  2. Basic machine startup procedures — follow step-by-step protocols to start agitators, shakers, or pumps with a trainer present in a processing facility.
  3. Temperature and pressure gauges — read and report instrument readings to a supervisor during routine monitoring shifts.
  4. Valves and manual controls — turn or move as directed to admit or drain materials through separation equipment under close oversight.
  5. Machine controls — observe and assist in adjusting settings for material flow and temperature under direct instruction from an experienced operator.
  6. Material samples — collect and visually examine for basic qualities such as clarity or cleanliness following standardized inspection checklists.
  7. Safety and environmental regulations — recognize and apply applicable rules while operating processing machines under supervision in a production environment.
  8. Equipment surfaces and connections — inspect for visible leaks, wear, or obvious malfunctions during pre-shift walkthroughs with a lead operator.
  9. Work instructions and safety data sheets — read and comprehend written operating procedures before performing assigned tasks on the production line.
  10. Personal protective equipment and hazard protocols — identify and use correctly when working around separation, filtration, or clarifying machinery.
Developing
Mid-level / Established
  1. Measured quantities of raw or semi-processed materials — independently load or transfer into designated processing equipment in accordance with batch specifications.
  2. Separation, filtration, and clarifying machines — operate routinely with reduced oversight to meet production targets while complying with safety and environmental standards.
  3. Process instruments including temperature, pressure, and flow meters — monitor continuously during a shift and take corrective action within established parameters.
  4. Valve sequences and control adjustments — execute to separate, filter, mix, or transfer materials efficiently during standard production runs in a manufacturing plant.
  5. Machine control settings — set up and fine-tune for varying material types or batch sizes based on work orders and prior operating experience.
  6. Sample quality attributes such as consistency, dryness, and texture — examine and compare against acceptance criteria, documenting results in shift logs or spreadsheet software.
  7. Centrifuge machines, conveyors, and pumps — start and monitor for abnormal vibration, noise, or output deviations and escalate issues appropriately.
  8. Equipment inspection findings — record in maintenance logs or ERP software and communicate clearly to maintenance personnel or shift supervisors.
  9. Time-sensitive processing tasks — prioritize and manage across multiple machines during a shift to maintain continuous material flow with minimal downtime.
  10. Verbal operating instructions and shift handover communications — listen actively and ask clarifying questions to ensure accurate task transfer between crews.
Proficient
Senior / Expert IC
  1. Full separation and filtration processing sequences — perform autonomously across diverse material types and non-routine batch conditions with consistent quality outcomes.
  2. Process deviations indicated by instrument readings — diagnose root causes using critical thinking and implement corrective adjustments to restore optimal operating conditions.
  3. Complex valve and control configurations — operate with precision to handle simultaneous material transfers, mixing, and filtration steps in a high-throughput production environment.
  4. Non-standard sample results such as unexpected turbidity or off-spec texture — analyze, document findings, and make informed disposition decisions without escalation.
  5. Mechanical malfunctions and efficiency losses — identify through systematic equipment inspection and coordinate timely repairs to minimize production impact.
  6. Process compliance with safety, energy, and environmental regulations — evaluate and verify across all assigned machines during routine and non-routine operations.
  7. Production and processing knowledge — apply to optimize machine parameters for yield, cycle time, or energy efficiency across the full scope of assigned operations.
  8. Shift production data — compile and analyze using spreadsheet software to identify trends, flag process drift, and support continuous improvement initiatives.
  9. Judgment on material quality hold or release decisions — exercise independently based on sample analysis, instrument data, and established quality control criteria.
  10. Peer operators and new hires — guide informally on correct machine operation techniques, safety practices, and sample evaluation methods on the production floor.
Advanced
Lead / Principal / Executive
  1. Departmental operating standards for separation, filtration, and clarifying processes — develop and maintain to ensure consistent quality, safety, and regulatory compliance across all shifts.
  2. Cross-shift production performance — analyze using ERP and spreadsheet data to set improvement targets and drive accountability among operators and leads.
  3. Equipment upgrade or replacement evaluations — lead by assessing mechanical efficiency, wear patterns, and production data to inform capital investment recommendations.
  4. Operator training programs — design and deliver covering machine setup, instrument monitoring, sample evaluation, and hazard recognition for Job Zone 2 production personnel.
  5. Process control strategies — establish for managing temperature, pressure, and material flow across multiple interconnected separation and filtration systems at organizational scale.
  6. Regulatory and environmental compliance programs — oversee and audit to ensure all machine operations meet applicable safety, energy, and environmental requirements facility-wide.
  7. Quality control analysis frameworks — implement and refine to standardize sample examination criteria and acceptance thresholds across production lines and product families.
  8. Cross-functional collaboration with maintenance, quality, and engineering teams — lead to resolve chronic equipment reliability issues and implement sustainable process improvements.
  9. Emergency response and hazard mitigation protocols — author and communicate to ensure all production staff can safely manage equipment failures, leaks, or process upsets.
  10. Organizational production culture — model and promote cautiousness, attention to detail, and integrity as behavioral standards throughout the separation and filtration workforce.
