Director, Anaerobic Wastewater Treatment

At Mobius Renewables , we’re helping lead the global energy transition by transforming waste into renewable energy and measurable decarbonization. We’re a fast-growing team of expert innovators, engineers, and problem-solvers committed to advancing global sustainability, fueling a circular economy, and creating a cleaner future for all. Join us and help shape the future of renewable energy.

Mobius Renewables operates a growing fleet of plants across the USA, currently 13, that convert

biogas derived from the anaerobic digestion of wastewater in covered lagoons into renewable

The Director of Anaerobic Wastewater Treatment anaerobic digestion will serve as the company’s

primary technical authority and point person for wastewater feedstock management, covered-

lagoon anaerobic digestion, and biogas generation across the anaerobic digestion portfolio. The

role will combine deep technical expertise with engagement with wastewater-generating

counter parties.

This role serves as the organization’s subject matter expert for industrial wastewater treatment,

with particular emphasis on high-strength organic waste streams, biological treatment, anaerobic

processes, and the integration of wastewater treatment with anaerobic digestion and renewable

The Director will work across Development, Engineering, Operations, Commercial, and Project

Execution to evaluate new opportunities, troubleshoot operating facilities, and drive continuous

improvement across the portfolio.

• Serve as Mobius Renewables’ primary technical authority for industrial wastewater treatment within the anaerobic digestion business.
• Evaluate wastewater characteristics including COD/BOD, TSS, FOG, nutrients, pH, alkalinity, toxicity/inhibition, temperature, and other factors affecting biological treatment and anaerobic digestion performance.
• Provide technical guidance related to aerobic and anaerobic biological treatment, clarification, solids handling, DAF, nutrient management, pretreatment, polishing, and related wastewater technologies.
• Maintain knowledge of emerging wastewater and resource-recovery technologies and assess their applicability to Mobius projects.
• Candidate should have strong technical background covering both the biology and physical operation of these systems, including: (i) Covered anaerobic lagoons and high-strength industrial wastewater; (ii) hydraulic short-circuiting, dead zones, retention time, and inlet/outlet configuration; (iii) sludge accumulation, lagoon capacity loss, dredging, and solids management; (iv) FOG accumulation, floating crusts, and fat-cap prevention or removal; (v) mixing, recirculation, heating, pH, alkalinity, nutrients, and organic loading;
  
  (vi) process upsets, inhibition, foaming, odor, and declining gas yield; (vii) cover condition, gas collection, condensate, pressure, and methane recovery; (viii) field diagnostics and practical corrective-action planning.
• Partner with Development and Commercial teams during evaluation of new wastewater and anaerobic digestion opportunities.
• Conduct or oversee technical due diligence of wastewater streams, existing treatment infrastructure, and proposed projects.
• Assess the treatability and variability of prospective feed stocks and wastewater streams and identify potential process risks.
• Identify opportunities to improve project economics through process optimization, resource recovery, reduced chemical or energy consumption, and improved biogas production.

• Partner closely with Operations to optimize wastewater treatment and anaerobic process performance across operating facilities.
• Diagnose process upsets and…
