Performance Engineer: Solar & BESS

CIG Energy

Location: Windermere, FL (or as otherwise approved)

Reports To: SVP of Operations 

Role Overview

CIG Energy is seeking a Performance Engineer: Solar & BESS to directly support the

execution of its multi-gigawatt utility-scale solar and battery energy storage portfolio.

This role is a core operational support function for the SVP of Operations, responsible

for ensuring that energy models, system designs, EPC assumptions, and financial

outputs are technically aligned, bankable, and executable in the field.

This position sits at the intersection of development, EPC execution, and capital

markets, and carries real responsibility for protecting project performance, revenue

assumptions, and long-term asset value. The Performance Engineer will serve as CIG

Energy’s technical authority on energy production, degradation, and system

optimization from greenfield development through operations.

Primary Responsibilities

· Act as the technical performance lead supporting Operations, responsible for

protecting energy yield, availability, and long-term performance assumptions across

CIG’s solar and BESS projects.

· Provide technical due diligence throughout the project lifecycle, from early-stage

development through construction and operations.

· Own weather resource assessment, energy production modeling, and loss analysis for

utility-scale solar PV and BESS projects.

· Serve as CIG Energy’s primary subject matter expert for solar production methodology

and energy modeling best practices.

· Lead system configuration, assumptions, and alignment for PVsyst, ensuring layouts,

losses, degradation, and operating assumptions are technically sound and execution-

ready.

· Review EPC technical exhibits, performance guarantees, and design assumptions to

ensure consistency with approved energy models and contractual obligations.

·      Work directly with the SVP of Operations to:

·      Identify performance risks early

·      Validate EPC and supplier assumptions

·      Support decision-making on layouts, equipment selection, and execution tradeoffs

Execution, Design & Optimization

· Support Project Execution teams in the development and coordination of optimized

layouts, incorporating constructability, access, topography, interconnection, and

construction sequencing constraints.

· Perform layout optimization, shading analysis, energy yield simulations, and detailed

loss assessments.

· Conduct site assessments, review topographical and geotechnical data, and analyze

meteorological datasets.

· Design and optimize BESS system layouts, including:

·      Degradation modeling

·      Augmentation strategies

·      Long-term capacity and performance planning

·      Collaborate closely with EPC partners, project managers, and internal stakeholders

to ensure design quality, constructability, and execution alignment.

Financial & Commercial Alignment

· Partner with Capital Markets and Financial Modeling teams to ensure energy model

inputs, production profiles, and degradation assumptions are fully aligned with financial

models and investment materials.

· Support lender, tax equity, and investor technical diligence by providing clear,

defensible performance assumptions and documentation.

· Assist in resolving technical questions related to performance guarantees, availability,

and long-term asset value.

Standards, Compliance & Continuous Improvement

· Maintain current knowledge of applicable codes and standards, including NEC, UL,

IEEE, IEC, and relevant industry guidance.

· Support performance monitoring, analytics, and reliability tracking across operating

assets.

·Identify opportunities to improve modeling accuracy, design standards, and execution

outcomes across the platform.

· Perform additional responsibilities as required to support operational execution and

business needs.

Minimum Qualifications

Minimum three (3) years of experience as a Performance Engineer or in a closely

related technical role within the renewable energy industry.Demonstrated hands-on

experience with:

o   PVsyst

o   Solar and BESS energy modeling software

o   Utility-scale project development and execution

o   Solar PV system design and performance modeling

o   Degradation analysis and long-term reliability tracking

o   Data analytics and performance monitoring

o   Advanced Excel modeling

· Strong understanding of renewable energy suppliers, EPC execution, markets, and

technology trends.

· Ability to operate independently, manage multiple priorities, and deliver high-quality

technical work in a fast-paced execution environment.
