Manager, Subsurface Engineering & Operations

Western Midstream is seeking an experienced leader for the role of Manager, Subsurface Engineering & Operations, based in The Woodlands, Texas. This position leads a multidisciplinary team of subsurface engineers, geologists, and tech supporting new and existing infrastructure for Western Midstream's produced water disposal program.

Responsibilities

• Prioritize and allocate team resources across basins and competing project demands
• Own the quality, consistency, and defensibility of subsurface deliverables — including injection interval selection, confining zone evaluation, and disposal capacity assessments
• Review and approve SWD well design, workover procedures, and injection performance recommendations
• Oversee preparation of early project scopes, estimates, and well location planning to support facility and gathering system design
• Serve as the subsurface interface to project management, operations, commercial, permitting, and regulatory affairs; translate technical findings into clear business recommendations
• Contribute to capital forecasting, AFE development, and project prioritization through high-quality early-phase deliverables
• Provide subsurface due diligence support for acquisition and divestiture evaluations
• Ensure work is executed in accordance with regulatory requirements (Texas Railroad Commission, New Mexico OCD, EPA UIC) and company safety and compliance standards
• Champion a strong safety culture within the team and in all field interactions

Qualifications

• Minimum of twelve (12) years' experience in the oil and gas industry; experience with saltwater disposal or injection systems strongly preferred
• Minimum of five (5) years directly supervising technical professionals, including performance management, development planning, and workload prioritization across disciplines
• Minimum of six (6) years' combined experience in drilling, completions, or injection/disposal operations
• Knowledge of industry standards for well design, completions, and workover operations
• Functional knowledge of drilling engineering and drilling operations
• Experience interfacing with state and federal regulatory agencies
• Experience with well location planning and permitting
• Working knowledge of production and reservoir engineering, subsurface characterization, or petrophysics a plus
• Demonstrated ability to lead through others — setting direction and standards rather than performing the analysis personally
• Excellent communication, problem-solving, and organizational skills, with the ability to present technical conclusions to non-technical stakeholders
• Self-motivated with the ability to manage multiple priorities in a dynamic environment
• Bachelor's degree in Petroleum, Civil, Mechanical, Chemical Engineering, or a related technical discipline required
