The Design-Build Estimator / Process Engineer operates within an ESCO environment, leading pre-construction efforts for water, wastewater, and industrial process projects from early opportunity assessment through development of complete design packages and cost estimates. This role focuses on scoping, designing, and pricing infrastructure improvements, working alongside Project Development teams responsible for energy performance contracting and ECM strategy. The position requires strong technical, estimating, and client-facing capabilities, with the opportunity to transition into project leadership through construction and commissioning phases.

• Lead full-cycle pre-construction for ESCO pursuits, owning all water, wastewater, and industrial process scopes from early opportunity evaluation through development of a complete, defensible design-build estimate, ensuring technical accuracy and commercial viability.
• Partner strategically with Project Development teams, aligning with energy performance contract objectives while independently scoping, designing, and pricing all water/wastewater and industrial infrastructure improvements.
• Drive client engagement during pre-construction, including leading site walks, technical workshops, and presentations, translating real-world field conditions into design assumptions, risk identification, and cost drivers.
• Perform in-depth facility condition assessments and due diligence, evaluating municipal and industrial treatment systems to identify deficiencies, upgrade opportunities, regulatory gaps, and execution risks.
• Develop basis-of-design (BOD) documentation and conceptual engineering packages, including process flow diagrams and preliminary designs that support go/no-go decisions, proposal development, and client approvals.
• Lead design-build estimating efforts across all phases, producing conceptual to definitive cost estimates, detailed scope narratives, equipment lists, and subcontractor bid packages aligned with project requirements and market conditions.
• Execute equipment selection, sizing, and pricing, coordinating directly with vendors and subcontractors to validate specifications, pricing accuracy, availability, and lead times.
• Conduct thorough RFP and technical document reviews, analyzing client specifications, drawings, and requirements to define scope, identify risks, and establish clear assumptions, exclusions, and clarifications.
• Provide advanced process engineering expertise, developing treatment system designs (biological, filtration, disinfection, membrane, solids handling), including hydraulic profiles, mass balances, and treatment train alternatives, while ensuring cross-discipline integration and regulatory compliance.
• Support or lead project execution post-award, transitioning estimates into delivery by managing design-build coordination, subcontractors, schedules, budgets, documentation, and client communication through construction and commissioning.

• Bachelor’s degree in Civil, Environmental, Chemical, Mechanical Engineering, or related field, with 5–8 years of experience in design-build estimating and/or process engineering for water and wastewater treatment…
