• Check and monitor gauges, controls, and HMI/touch screen control systems to ensure proper equipment operation.
• Follow all standard operating procedures (SOPs) and production guidelines during batch preparation and processing.
• Keep detailed and accurate records of batch formulations, process parameters, and production outcomes.
• Work with batch sizes up to 4,000 gallons, ensuring consistency and quality throughout the mixing process.
• Monitor running machinery such as pumps, mixers, and milling machines, and respond promptly to any irregularities.
• Notify maintenance immediately if any equipment or process issues arise, and support safe resolution of problems.
• Perform housekeeping duties while machines are running or when batches are completed, including sweeping, cleaning, and maintaining a tidy work area.
• Communicate batch records, production status, and any issues to the next shift and supervisors to ensure smooth handoffs.
• Work side by side with a helper, providing guidance on basic job duties, safety practices, and proper procedures.
• Start in a labor-focused capacity to learn the operation and progressively move into full formulating and batch mixing responsibilities.
• Assist with packaging, staging, and preparing orders as needed to support overall production requirements.
• Collaborate closely with supervisors and team members to meet production goals and maintain quality standards.

Why Work Here?

You will join a modern, safety-focused organization that invests in clean, well-maintained facilities and structured processes. The company offers strong benefits and emphasizes employee well-being, with temperature-controlled environments and clear operating procedures. You will receive thorough training, opportunities to expand your skills in chemical manufacturing, and the chance to work in facilities that balance organized operations with robust production activity.

Work Environment

The work takes place in temperature-controlled chemical manufacturing facilities that include production floors and warehouse areas. One site features a modern, very clean, and recently remodeled environment with a smaller workforce, highly organized inventory, and fewer lines, kettles, fillers, and blenders. The other site is larger, with more production lines and a higher volume of work, creating a more fast-paced and sometimes chaotic environment, but it remains in good condition and is also temperature controlled. Both locations place a strong emphasis on safety, with security checkpoints at the larger facility and multiple break rooms available for employees. Operations at both sites involve manufacturing chemical products, bottling, staging, and shipping, with chemicals that are described as not harmful. You will work on structured shifts, with opportunities on first, second, and third shifts, following a Monday–Friday schedule for first and second shifts and a Sunday–Thursday night schedule for third shift.
