Process Engineer - Water​/Wastewater Engineering

Overview

We have an opening for Process Engineers to support projects across the Process Industries and Water/Wastewater markets. You will be part of a team that develops practical, constructible process engineering solutions for customers across North America. The role covers evaluation, selection, design, optimization, and implementation of process systems for Kiewit’s EPC projects and pursuits. Projects may include data centers, gasification facilities, biofuels, renewable fuels, industrial process facilities, industrial water treatment, wastewater treatment, water reuse, and related process infrastructure.

The candidate will develop process engineering deliverables, collaborate with multi-disciplinary teams, evaluate vendor data, support process simulations, and contribute to technical decisions throughout the project lifecycle. Strong communication, technical curiosity, and the ability to work within project budgets and schedules are essential.

The Kiewit Water Engineering team includes process, mechanical, piping, electrical, instrumentation and control, structural, and civil disciplines. We focus on collaborative Design-Build (progressive and/or fixed price) and EPC delivery models for complex water projects across North America.

This role is based in Lenexa, Kansas or Lone Tree, Colorado. Relocation is offered. Consideration may be given for candidates with senior experience in Municipal and Industrial Wastewater and water treatment design with EPC project experience to be in other Kiewit hub locations.

• Provide process engineering support for process industries and water/wastewater projects, including evaluation, selection, design development, optimization, and lifecycle cost considerations.
• Develop, prepare, and review process engineering deliverables such as block and process flow diagrams, P&IDs, process simulations, design basis documents, line lists, calculations, equipment sizing, datasheets, technical specifications, reports, drawings, and applicable design standards.
• Perform process design activities related to hydraulics, material balances, utility requirements, equipment sizing, process controls, interdisciplinary coordination, and vendor data / supplier documentation evaluation.
• Collaborate with multi-disciplinary project teams (mechanical, piping, electrical, instrumentation and controls, civil, structural, estimating, construction, and commissioning) to support technical deliverables and maintain quality and consistency.
• Communicate progress, deadlines, deliverable status, and technical issues through project meetings, design reviews, and status updates.
• Provide technical support for design, construction, equipment, commissioning, and operations within established project scope, schedule, and budget.
• Contribute to the improvement of company resources, tools, workflows, and design standards while developing process engineering knowledge through active project work.

• Bachelor’s degree or higher in Chemical, Mechanical, Civil/Environmental, or related Engineering discipline.
• 3 to 8 years of experience in process development, conceptual/detailed design, process engineering, or similar technical functions within process industries, industrial facilities, water/wastewater, or related markets.
• Experience developing or supporting engineering deliverables such as block/flow diagrams, P&IDs, design basis documents, equipment datasheets, specifications, line lists, calculations, and technical reports.
• Experience with process simulation, hydraulic modeling, equipment sizing, process controls coordination, and interdisciplinary engineering coordination is preferred.
• Experience performing vendor data reviews and technical evaluations of equipment or process systems is preferred.
• Professional Engineer registration preferred, or ability and intent to pursue PE registration within the next few years.
• Understanding of applicable regulations, codes, standards, and permitting related to process systems, industrial facilities, water treatment, wastewater treatment or discharge requirements is preferred.
• Willingness and ability to travel intermittently, with up to 20% to 30% travel expected.
