OVERVIEW: McKim & Creed is seeking a Senior Landfill Leachate Treatment Process Engineer to join our successful and growing team and help expand our presence in the solid waste market. This is an opportunity for an experienced treatment professional to step directly into multiple active landfill leachate treatment projects while helping build the next phase of our solid waste and environmental treatment practice.

The successful candidate will have an immediate opportunity to contribute to ongoing projects involving landfill leachate treatment, PFAS and emerging contaminants, biological treatment, membrane systems, reverse osmosis, activated carbon, advanced treatment processes, residuals management, and treatment system integration
. The role will work closely with our process, mechanical, electrical, instrumentation and controls, civil, and environmental professionals to deliver practical, implementable solutions for our clients.

Our work in the solid waste market is growing rapidly, with landfill owners and operators increasingly looking to McKim & Creed for solutions to complex leachate treatment and water quality challenges. We are looking for a senior engineer who brings strong process engineering experience, enjoys solving difficult treatment problems, and can work collaboratively with multidisciplinary teams to move projects from evaluation and treatability through design, implementation, startup, and optimization.

This position is well suited for a senior engineer who wants more than a single-project technical role. You will have the opportunity to jump immediately into meaningful active projects, influence how solutions are developed and delivered, and help shape a growing solid waste practice within an established multidisciplinary engineering firm.

WHAT YOU’LL DO:

• Serve as a senior technical resource for landfill leachate treatment projects ranging from process evaluations and treatability studies through detailed design, construction, startup, and optimization.
• Immediately contribute to multiple active leachate treatment projects for landfill and solid waste clients.
• Develop and evaluate treatment process alternatives based on leachate characteristics, discharge requirements, operational objectives, lifecycle cost, and site constraints.
• Lead or support process design activities including basis-of-design development, process calculations, mass balances, process flow diagrams, P&IDs, equipment sizing and selection, specifications, control narratives, and system layouts.
• Evaluate and integrate treatment technologies such as biological treatment, membrane systems, reverse osmosis, activated carbon, advanced oxidation, and other physical/chemical treatment processes.
• Address challenging constituents including PFAS, metals, ammonia, organics, dissolved solids, and other conventional and…
