About The Position

The Mechanical Engineer is the Owner's technical lead for mechanical and balance-of-plant (BOP) scope on gas-fired power projects. This Owner-side role protects Pacifico's interests in performance, reliability, cost, and schedule while working alongside the Owner's Engineer, EPC contractor, turbine OEMs, and lenders' engineers. The engineer reviews and challenges EPC and OEM engineering, manages mechanical equipment procurement and interfaces, and carries the design through construction, commissioning, and handover. The role covers mechanical design review and BOP systems, including fuel gas conditioning and compression, cooling systems, ORC waste heat recovery, compressed air, fire protection, water and wastewater, and HVAC. It also includes performance and heat-rate evaluation; equipment procurement and vendor management; field oversight of installation and testing; commissioning and turnover; and commercial and project support, including assessment of EPC change orders, RFIs, and technical deviations. The position is based in Dallas, with travel to Texas project sites of up to 30–40% during construction peaks.

Requirements

B.S. in Mechanical Engineering from an ABET-accredited program.
At least 8 years of mechanical engineering experience on thermal power plants (simple cycle, combined cycle, or cogeneration), with an EPC contractor, Owner, OEM, or Owner's Engineer.
Hands-on knowledge of gas turbine auxiliaries and BOP systems, including fuel gas, cooling, compressed air, fire protection, and water treatment.
Working command of ASME B31.1/B31.3 and NFPA 850.
Ability to read and mark up P&IDs, isometrics, and vendor drawings.
At least one project carried through construction and commissioning in the field.
Clear written and verbal communication skills, and ability to hold a technical position with contractors and OEMs.
Willingness to be based in Dallas and travel to Texas sites up to 30–40% during construction peaks.

Nice To Haves

Professional Engineer (PE) license in Texas, or EIT.
Experience with industrial or aeroderivative gas turbines (e.g., Siemens Energy, GE Vernova, Baker Hughes, Ansaldo) and their OEM interfaces.
Exposure to waste heat recovery (ORC or HRSG), fuel gas compression, or behind-the-meter/islanded generation.
Owner's representative experience on lump-sum or EPC contracts, including change order and claims review.
Experience in Texas/ERCOT, or on data center or large industrial power supply projects.
Familiarity with AFT Fathom/Arrow, Thermoflow (GT PRO/PEACE), Navisworks, or AVEVA model review tools.

Responsibilities

Review EPC and OEM engineering deliverables, including PFDs, P&IDs, heat and mass balances, equipment datasheets, specifications, plot plans, and 3D models.
Own mechanical BOP scope, including fuel gas conditioning and compression, cooling systems, ORC waste heat recovery, compressed air, fire protection, water and wastewater, and HVAC.
Lead or support plant performance and heat-rate evaluations, degradation analysis, and ambient-correction analysis.
Check designs against applicable codes and standards, including ASME B31.1/B31.3, ASME BPVC, API, NFPA, and ERCOT/TCEQ-driven requirements affecting mechanical scope.
Run or participate in HAZOP, constructability, and design reviews, and track comments to closure.
Write technical specifications and evaluate bids for mechanical equipment such as gas compressors, pumps, heat exchangers, fin-fan coolers, tanks, valves, and piping.
Support gas turbine and long-lead equipment procurement, including technical clarifications, scope splits, and interface lists with OEMs.
Witness factory acceptance tests and expedite vendor data and quality documentation.
Provide Owner oversight in the field for mechanical installation, piping, hydrotests, flushing, and QA/QC records.
Review and approve commissioning procedures and support start-up, performance, and reliability testing.
Ensure turnover packages, O&M manuals, and as-builts are complete before handover to operations.
Assess EPC change orders, RFIs, and technical deviations for cost, schedule, and performance impact.
Contribute to technical due diligence for new sites and reporting for investors, lenders, and the Independent Engineer.
Support early-stage concept and configuration studies for pipeline projects.
