Overview

ExxonMobil is seeking a Senior Water Treatment Engineer (Environmental Engineer III) to join the water team within Environmental Engineering at ExxonMobil Technology and Engineering (EMTEC). The team is the corporate technical hub for water and wastewater treatment, supporting upstream, low carbon, and downstream operations worldwide, with most work centered on downstream refining and chemical complexes. Driven by country programs and a need for deep domain expertise, this critical role spends about 70% of its time troubleshooting and solving day-to-day problems at operating facilities, with the rest supporting early-phase project decisions on technology selection and design basis. The role is based at the Houston campus, and candidates located in Baton Rouge or Beaumont, close to ExxonMobil complexes, are also welcome with regular visits to Houston. This is a 12-month contract with strong potential for extension.

Responsibilities

• Troubleshoot and resolve day-to-day operational issues in raw water, utilities water, wastewater, and produced water systems at ExxonMobil sites worldwide.
• Serve as the go-to technical resource for site operations teams that escalate water treatment problems they cannot solve locally.
• Lead technical investigations, root cause analyses, treatment chemistry evaluations, and corrective actions to improve system performance and reliability.
• Solve problems through chemical treatment programs, equipment and process changes, or both, depending on the facility and water stream.
• Optimize biological wastewater treatment, ion exchange, membrane, and oil-water separation systems at operating brownfield facilities.
• Support boiler feed water production and water chemistry programs that are critical to site utilities and steam systems.
• Guide early-phase (Stage 2 and Stage 3) capital projects on treatment technology selection and development of the design basis.
• Provide technical oversight through design, startup, and performance optimization for existing and greenfield facilities.
• Evaluate and deploy established, emerging, and proprietary water treatment technologies in line with engineering standards and best practices.
• Advise management on the technical, operational, business, and sustainability risks of water treatment, reduction, and reuse solutions.
• Mentor and coach early- and mid-career engineers, including the Kuala Lumpur technology center team, to build technical capability.
• Support on-site assessments at Gulf Coast and other North American complexes, such as Baytown, Beaumont, and Baton Rouge, when critical issues arise.

Qualifications

Required Qualifications

• 10+ years of experience in industrial water, wastewater, and/or produced water treatment, water reuse, or process engineering.
• Hands-on troubleshooting of operating water or wastewater systems within the last 5 years, as the main focus of recent experience rather than project or design work.
• Deep expertise in at least one of the following: biological wastewater treatment, water chemistry (boiler feed or produced water), ion exchange and membrane processes, or oil-water separation and produced water treatment.
• Track record of diagnosing and fixing treatment upsets through chemical treatment programs, equipment and process changes, or both.
• Proven ability to lead multidisciplinary teams and influence technical decisions across organizations.
• Strong analytical, problem-solving, and communication skills, with close attention to detail in technical documentation.
• Proficiency in Excel and Word, as the team's design practices and tools are largely Excel-based.
• Based in, or able to relocate to, the Houston, Baton Rouge, or Beaumont area, with the ability to be on the Houston campus regularly.
• Ability to flex working hours for occasional early morning and evening calls with global teams.
• Ability to work effectively both independently and as part of a collaborative team.

Preferred Qualifications

• Industrial background in oil and gas, refining, petrochemicals, chemicals, power generation, mining, or manufacturing.
• Municipal operations experience with strong hands-on troubleshooting is also considered.
• Working experience across more than one water stream (raw water, utilities water, industrial wastewater, and produced water).
• Experience with boiler feed water treatment and steam system chemistry.
• Startup and performance troubleshooting experience on new units, as a complement to ongoing operations support.
• Early-phase project experience in technology selection and design basis development.
• Proficiency with water chemistry modeling software such as OLI, or with wastewater process modeling tools.
• Experience mentoring or developing junior engineers.
