Job description

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.

Facility Overview

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 feedstocks, produces pipeline‑quality renewable natural gas, manages digestate, and treats process wastewater through an on‑site membrane bioreactor system.

Position Summary

Reporting to the Plant Manager, the Wastewater Manager leads day‑to‑day wastewater treatment performance, reliability, optimization, and continued improvement. The position maintains a strong hands‑on presence in the plant; helps develop Wastewater Technicians; and works closely with the Operations Manager, Plant Engineer, Lab Manager, Maintenance Manager, wastewater consultants, third‑party engineers, vendors, and contractors. The operation treats high‑strength wastewater with influent ammonia concentrations averaging approximately 4,000 mg/L and dewaters approximately 250,000 gallons per day of sludge using screw presses. Strong practical expertise in biological nitrogen removal and solids handling is essential.

Key Responsibilities

Own day‑to‑day wastewater treatment performance, reliability, and optimization.

Maintain a strong hands‑on presence in the plant, including troubleshooting, sampling, testing, process adjustments, and equipment evaluation.

Manage and optimize nitrification and denitrification under high‑ammonia loading conditions.

Understand and interpret process‑control testing including NH3, NO2/NO3, COD, alkalinity, MLSS/MLVSS, DO, ORP, OUR/SOUR, and related analyses.

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.

Provide management‑level response to significant wastewater process or equipment issues outside normal working hours when necessary.

Qualifications

5-7+ years of meaningful wastewater treatment experience, including significant hands‑on biological treatment experience.

Strong practical knowledge of activated sludge, nitrification/denitrification, process control, laboratory analysis, solids management, and mechanical dewatering.

Demonstrated ability to diagnose biological process problems using laboratory data and operating trends.

Strong leadership, communication, decision‑making, and project‑management skills.

A specific college degree is not required. Relevant technical expertise and demonstrated experience are valued over formal education.

Required Skills and Competencies

Ability to troubleshoot treatment performance, equipment, instrumentation, and operating issues in a hands‑on plant environment.

Sound judgment in using sampling results, operating trends, and process data to prioritize actions and make timely operating decisions.

Clear written and verbal communication skills for documenting operating conditions, reporting results, coordinating corrective actions, and working effectively across plant, technical, compliance, vendor, and laboratory teams.

Strong organization and follow‑through, including the ability to manage priorities, maintain accurate records, support SOP development, and drive corrective actions through completion.

Proficiency with Microsoft Excel and basic data tracking, reporting, and trend‑analysis tools.
