Senior Process Engineer

Play an integral role in Worley’s Process Engineering team, helping deliver the critical infrastructure and processing facilities that support energy, chemicals, resources, and emerging energy markets throughout North America. As energy systems continue to evolve, you will contribute to projects that improve reliability, operational efficiency, process safety, emissions performance, and asset productivity across refining, pipeline, gas processing, terminal, midstream, carbon capture, and related energy infrastructure facilities.

Based in Denver, you will join a multidisciplinary engineering team that supports some of North America’s most complex energy projects. Working alongside pipeline, mechanical, civil, structural, electrical, instrumentation, and project professionals, you will develop process solutions that enable customers to optimize operations, increase capacity, improve safety performance, and support the transition to a more sustainable energy future. Through technical excellence, innovation, and collaboration, you will help customers solve critical challenges across the energy value chain.

As a Senior Process Engineer, you will provide process engineering services to Worley and its customers while serving as a technical leader within the Process Engineering team. You will perform process engineering activities across refining, pipeline, gas processing, terminal, midstream, petrochemical, and related energy infrastructure projects while mentoring junior engineers and supporting multidisciplinary project execution.

You will develop, evaluate, and optimize process systems that support the safe, reliable, and efficient transportation, processing, storage, and handling of hydrocarbons and other energy products. Working closely with project teams and customers, you will translate operational objectives into practical engineering solutions that improve performance, maintain regulatory compliance, and deliver long‑term business value.

In this role, you will work with experienced multidisciplinary engineers to deliver safe, efficient, and sustainable solutions for energy transportation, processing, and delivery projects.

You will contribute across the full project lifecycle, from early concept studies through detailed design, procurement, construction, commissioning, and startup, while supporting customers in both traditional and emerging energy sectors.
