Senior Mechanical Project Engineer

About us:

Pacifico Energy is a global energy infrastructure firm supporting complex, large load projects from development through to operations. The company serves as a trusted partner across engineering, financing, construction, and optimization, delivering tailored power solutions for large energy users, including data centers. With a proven international track record and over 15 years as a large-scale developer, Pacifico brings speed and knowledgeable oversight to projects from start to finish.

We are hiring a Senior Mechanical Project Engineer to serve as the owner’s technical authority for all matters related to design, procurement, and construction of multi‑unit simple cycle gas turbine power generation facilities with battery energy storage and associated auxiliary systems. The position supports projects across the company’s power generation development and execution portfolio but may become dedicated to a specific project site during the execution phase.

This role provides engineering leadership late‑stage project development through procurement, EPC execution, commissioning, and long‑term asset operation. The position is responsible for ensuring gas turbine project solutions meet project objectives for performance, efficiency, reliability, environmental compliance, lifecycle cost, and regulatory permitting.

The successful candidate will represent the company as the technical interface with equipment OEMs, Owner’s Engineers, EPC contractors, and other internal and external stakeholders, ensuring best‑in‑class outcomes for owner‑developed and owner‑operated generation assets.

• Act as the company’s subject matter expert and technical lead for power systems typically required for gas turbine power generation facilities.
• Provide oversight and Owner’s side coordination for major equipment definition, design and integration, including:
• Gas turbines
• SCRs
• Heat recovery systems when applicable
• Fuel gas and systems
• Oil lubrication and hydraulic systems
• Inlet air filtration, conditioning, and cooling
• Exhaust systems, silencers, and stack interfaces
• Cooling water systems and heat rejection auxiliaries
• Buildings, enclosures, ventilation, and fire protection
• Black start engines
• Ensure major equipment and plant design solutions align with owner priorities including long‑term operability, maintainability, availability, and lifecycle economics.

• Identify and confirm boundary conditions, performance specifications, and scope of major equipment packages.
• Ensure integration at scope interfaces between suppliers as well as between owner, offtaker, and other external parties.
• Oversee mechanical packaging, piping layouts, and equipment integration for gas turbine and balance‑of‑plant auxiliary systems, including interfaces with advanced augmentation and hybrid configurations.
• Conduct feasibility studies, conceptual design evaluations, and simplified engineering analyses, including:
• Heat and mass balance development
• Thermal performance assessments
• Water/heat balance calculations for plant auxiliary and cooling systems
• Interpret, validate, review, and otherwise perform owner‑level oversight of key engineering deliverables, including:
• Equipment data sheets and contract specifications
• Process Flow Diagrams (PFDs)
• Piping & Instrumentation Diagrams (P&IDs
  )
• Thermal system design documentation and performance inputs

• Support early‑stage project development activities including technology screening, conceptual design, and performance definition.
• Lead evaluation and selection of gas turbine technologies and configurations (simple cycle, combined cycle, CHP, and novel data center primary power solutions).
• Develop owner‑level technical requirements, performance guarantees, and specification frameworks for procurement and EPC contracting.

• Drive the assessment and deployment of advanced technologies to improve plant efficiency, flexibility, and emissions performance, including:
• Inlet air chilling and cooling systems (mechanical chillers, thermal storage)
• Turbine power…
