Parsons is hiring an experienced mechanical engineer to work on infrastructure projects in the oil and gas, wastewater, and chemical industries. The role involves applying standard mechanical engineering techniques and analyses, potentially using CAE/CAD applications, in a flexible, team-oriented environment. It may be performed virtually but may require regular travel to customer facilities in the Houston, Texas area, as well as travel to supplier, client, or construction sites. The engineer designs and evaluates natural gas pipeline systems, stations, terminals, metering facilities, pressure regulation systems, and related equipment. The position supports permitting, procurement, construction, and project delivery, including coordination with customers, vendors, contractors, permitting entities, and multidisciplinary engineering teams. The role also provides technical guidance to designers and lower-level engineers and contributes to risk assessment activities such as PHAs and HAZOPs. This position is part of Parsons’ Critical Infrastructure team, which plans, designs, builds, and modernizes infrastructure intended to connect and protect communities and support economic growth, mobility, sustainability, and resiliency. The role requires work in office, industrial, construction, and wastewater treatment environments, with occasional exposure to outdoor weather, noise, industrial equipment, confined spaces, chemicals, and uneven terrain. Required personal protective equipment may include a hard hat, safety glasses, hearing protection, gloves, flame-resistant clothing, and respiratory protection when necessary.
