Job description

Pacifico Energy develops, finances, builds, and operates energy infrastructure that powers businesses and communities. In the U.S., we are tackling one of the biggest challenges facing AI and large-scale data centers: access to reliable power. Our private grids bring dedicated generation and energy storage directly to customers, helping projects move forward without waiting for traditional utility connections. We draw on Pacifico Energy Group’s experience across the U.S., Japan, South Korea, and Vietnam, spanning solar, wind, battery storage, and natural gas. Joining Pacifico means helping turn ambitious energy projects into operating infrastructure, with work that connects directly to the people and businesses building the future of AI.

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.

What you get to do:

Owner’s Engineering Leadership – OCGT Projects

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:
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
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

Project Development & Technology Selection

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.

Technology Innovation & Efficiency Optimization

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 augmentation (fogging, wet compression, intercooling, absorption chillers, organic rankine cycle (ORC) and other concepts)
Advanced auxiliary integration for high reliability and extreme climate operation
Lead emissions control and compliance technology evaluations, including:
Selective Catalytic Reduction (SCR) for NOx reduction
Oxidation catalysts (OCR/CO catalysts) for CO/VOC control
Comparative evaluation of OCR vs Inlet Chilling
Combined cycle efficiency optimization versus post‑combustion carbon capture (CCUS) integration
Impacts of capture systems on turbine performance, backpressure, auxiliary load, and permitting
Provide technical input to business case development, including CAPEX/OPEX estimation and lifecycle valuation.

Procurement, Contracting & OEM Management

Lead technical development of RFQs, bid specifications, and contractual performance requirements for major equipment and EPC contracts.
Conduct technical bid evaluations and support commercial negotiations with OEMs and EPC partners.
Review and manage vendor deviations, change orders, warranty provisions, and long‑term service agreement interfaces.
Ensure equipment supply aligns with project schedules, risk posture, and owner investment objectives.

Compliance & Risk Management

Lead and participate in formal risk review activities including:
HAZOP (Hazard and Operability) studies
HAZID (Hazard Identification) workshops
Identify technical, operational, and safety risks associated with gas turbine packages and auxiliary systems, and develop practical mitigation strategies in coordination with EPCs, OEMs, and internal stakeholders.
Ensure compliance with applicable safety, environmental, and regulatory requirements across project phases, including:
Air permitting and emissions modeling support
Applicable codes, standards, and owner safety requirements
Support integration of risk mitigation and compliance requirements into design, procurement, construction, and commissioning activities.

Regulatory Compliance & Air Permitting Support

Provide owner‑level engineering support for all gas turbine generation related environmental and regulatory requirements.
Support preparation of air permit applications and compliance documentation, including emissions modeling inputs and control technology justification.
