Core Responsibilities

Primary Functions

Operate, set up, and shut down high-pressure metering and mixing systems (metering pumps, proportioners, impingement mixers, and static mixers) according to production schedules and written work orders to ensure accurate blend ratios and finished-product consistency.
Accurately weigh, measure and prepare raw materials, additives, catalysts and blowing agents following specified formulations and batch records, ensuring all materials are within required specifications before mixing.
Monitor and adjust temperature, pressure, flow rate and other critical process parameters during mixing and dispensing to maintain product quality and prevent off-spec batches.
Perform in-line and lab sampling of mixed foam batches and perform routine QC checks (density, viscosity, gel time, tack-free time, cell structure inspection) to verify conformance to product specifications.
Record batch information, process parameters, material lot numbers and deviations in production logs, batch records and electronic systems to maintain full traceability and regulatory compliance.
Troubleshoot mixing equipment and process issues in real time (e.g., flow imbalances, pump calibration drift, nozzle/line blockages) and coordinate with maintenance to effect swift repairs and minimize downtime.
Execute clean-in-place (CIP), disassembly and cleaning of mixers, hoses and guns according to standard operating procedures and safety protocols to prevent cross-contamination and ensure equipment readiness.
Follow Safety Data Sheets (SDS), hazardous materials handling procedures, and company safety policies when receiving, storing, and using raw chemical components, including proper use of PPE and spill response.
Participate in start-up and shutdown procedures for foam production lines, including pre-start inspections, calibration checks and verification of formulation settings for each production run.
Set up and perform line changeovers between products, including purging lines, changing hoses/nozzles, updating recipes in control systems and documenting changeover steps for quality assurance.
Maintain inventory of raw materials and consumables used in mixing operations, report low stocks, and assist with FIFO rotation to ensure proper material usage and prevent expired or degraded inputs.
Work with R&D, quality, and production engineers to validate new formulations, scale pilot recipes to production, and implement process improvements that improve yield, reduce waste and optimize cycle time.
Ensure compliance with environmental regulations and internal policies related to emissions, waste disposal and chemical storage, including proper labeling, bunding and secondary containment where required.
Train and mentor junior mixers and temporary staff on mixing procedures, equipment operation, safety protocols and quality expectations to build a reliable, cross-trained production team.
Maintain housekeeping standards in the mixing area, ensuring workspaces are clean, organized and free of slip/trip hazards to support a safe production environment.
Execute preventative maintenance tasks and basic mechanical adjustments on pumps, valves and mixers as directed by maintenance schedules to reduce unplanned downtime.
Interface with downstream production and packaging teams to coordinate throughput, resolve handoff issues, and ensure continuous product flow and on-time delivery.
Respond to quality events by containing suspect product, quarantining affected materials, documenting incident details and supporting root cause analysis efforts.
Maintain and update standard operating procedures (SOPs), batch records and work instructions to reflect current best practices and regulatory requirements.
Operate forklifts and chemical transfer equipment safely to move drums, totes and pallets of raw materials into position for mixing operations where certifications permit.
Participate in continuous improvement initiatives, such as kaizen events and 5S projects, to increase operational efficiency, reduce waste and improve workplace organization.

Secondary Functions

Support ad-hoc lab testing requests and collaborate with quality labs to expedite root-cause testing for off-spec materials.
Assist with material receiving and raw material inspection, including verifying documentation, conducting visual inspections and entering receipts into inventory systems.
Contribute to shift handover reports and communicate open issues, work-in-progress batches and priority tasks to incoming shift personnel to maintain production continuity.
Help develop operator training materials, visual aids and competency checklists to accelerate onboarding and reduce variability in mixing operations.
Participate in safety committees and incident investigations by providing firsthand process knowledge and recommending corrective actions.
Collect, log and report production metrics (yield, scrap, downtime, cycle time) to supervisors and continuous improvement teams to support data-driven decision making.
