Lead Process Engineer

Overview

Lead Process Engineer – Advanced Sludge Treatment – Water Sector

Are you ready to lead the next generation of low-carbon wastewater and resource recovery projects?

What You’ll Do

• Lead end-to-end process design for sludge lines, including thickening, digestion (conventional and advanced), dewatering, thermal hydrolysis, and sidestream treatments.
• Deliver thermal conversion projects, integrating pyrolysis and gasification with energy recovery systems (CHP, boilers, heat recovery) and evaluating biochar/syngas quality.
• Develop mass and energy balances, build and calibrate dynamic models (BioWin, SUMO, or equivalent), and optimise biogas yield and energy performance.
• Evaluate multiple technology options, considering CAPEX/OPEX, operability, carbon impact, and risk, to define the most sustainable solutions.
• Produce process flow diagrams (PFDs), P&IDs, equipment specifications, and control narratives, collaborating closely with multidisciplinary teams, clients, and regulatory bodies.
• Support commissioning, troubleshooting, and performance optimisation to ensure projects meet or exceed design targets.

What You Bring

• Degree in Chemical, Process, or Environmental Engineering (Master’s preferred); CEng or near-chartered.
• 10-20 years’ experience in wastewater/sludge treatment, including AD, thermal hydrolysis, dewatering, and sidestream optimisation.
• Proven experience in thermal conversion technologies (pyrolysis, gasification) and integration with energy systems.
• Strong leadership in FEED and EPC projects, managing teams and delivering complex designs on time and within budget.
• Proficiency in process simulation and modelling (BioWin, SUMO, Aspen HYSYS, Thermoflex, MATLAB/MATHCAD) to underpin design and operational decisions.
• Excellent communicator and stakeholder manager, capable of presenting technical solutions to clients and guiding project teams.

Why This Role?

• Lead projects at the forefront of low-carbon water and energy innovation.
• Work with cutting-edge technologies and sustainable resource recovery solutions.
• Shape the future of wastewater treatment while making a real environmental impact.
• Competitive package with skilled visa sponsorship available; eligible to apply for settled status next year.
