    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
