Wastewater Manager

Location: Plant-based position located at the Carbon Cycle North Carolina facility in Warsaw, North Carolina

Job: Wastewater Manager

Carbon Cycle North Carolina LLC is seeking an experienced, hands‑on Wastewater Manager to lead the operation, performance, and continued improvement of its industrial wastewater treatment facility. This position has primary ownership of wastewater operations and directly supports a team of Wastewater Technicians in support of safe, reliable, and compliant plant operations.

As global industries face increasing pressure to decarbonize, renewable natural gas (RNG) is emerging as a practical and scalable solution. C2NC is building the infrastructure to support that transition - turning overlooked resources into clean energy while prioritizing transparency, environmental integrity, and operational precision. Here’s how we’re moving forward.

C2NC develops and operates industrial-scale anaerobic digestion facilities that transform organic byproducts into pipeline‑grade renewable natural gas. These facilities not only reduce methane emissions but also offer a sustainable, circular alternative to traditional energy sourcing. Our flagship site in Warsaw, NC is one of the largest of its kind in the Southeast - and it’s just the beginning.

The Warsaw facility receives agricultural and organic feed stocks, produces pipeline‑quality renewable natural gas, manages digestate, and treats process wastewater through an on‑site membrane bioreactor system.

Determine when additional sampling or diagnostic testing is needed and translate results into operating decisions.

Manage sludge handling and screw‑press dewatering, including polymer optimization, cake solids, capture efficiency, and equipment performance.

Lead wastewater‑related capital and improvement projects, including equipment selection, vendor coordination, engineering, construction, commissioning, and startup.

Work with the EHS Manager to support environmental compliance, sampling, reporting, and record‑keeping.

Develop SOPs, operating targets, troubleshooting procedures, and process‑control strategies.

Coordinate effectively with engineers, consultants, equipment manufacturers, chemical suppliers, laboratories, and contractors.
