Process Technician

Process Technician About Us Queens Carbon is pioneering breakthrough technology to efficiently produce carbon-neutral cementitious materials — without the green premium. Our patented manufacturing process, known as “The Instant Pot of Cement Manufacturing,” uses water to lower production temperatures, dramatically improving energy efficiency and cutting emissions. Backed by Breakthrough Energy Fellows, ARPA-E, world-class climate investors, and strategic partners, we’re proving that sustainability can be both economically viable and globally competitive. Position Overview   As a Process Technician at Queens Carbon, you will maintain, operate, and improve pilot-scale equipment and processes related to the development of novel cement and supplementary cementitious materials. In this role, you will primarily work with the Product Evaluation and Demonstration team to plan and execute scale-up campaigns, ensure and improve process reliability, and contribute to process optimization efforts. You will also work with the Engineering team to fabricate components, modify process equipment, conduct preventative maintenance, and support facility improvement projects. This role will support operation of both mini-pilot systems and an in-house pilot-scale demonstration system to validate scalable, repeatable operation. Roles  and Responsibilities Safely operate and monitor pilot- and demonstration-scale process equipment in accordance with standard operating procedures (SOPs), commissioning plans, and experimental protocols. Prepare equipment and materials for experimental and scale-up runs, including system setup, calibration, inspection, and post-run cleaning. Monitor key process variables, review trends, record operating data, and respond appropriately to alarms, deviations, or abnormal conditions. Execute defined sampling and material handling plans, ensuring accurate labeling, traceability, documentation, and timely delivery of samples to the laboratory for characterization and quality assurance testing. Perform routine preventative maintenance and basic troubleshooting of mechanical, electrical, and instrumentation components to support safe, reliable operation. Support the installation, shakedown, commissioning, and startup of new pilot and demonstration-scale equipment, including first-of-a-kind systems. Maintain clear and accurate records of equipment performance, maintenance activities, system modifications, and operational observations to support data integrity and scale-up learning. Identify and communicate opportunities for process optimization, reliability improvements, and equipment or procedural enhancements, with particular attention to safety, operability, and repeatability. Interface with process controls systems (PLC/HMI) to monitor operating conditions, respond to alarms, and provide operational feedback to engineering teams to improve system reliability and usability. Collaborate closely with R&D scientists, engineers,…
