Title: Manager, Development Engineering
Treaty Oak Clean Energy, LLC (Treaty Oak) is a clean energy platform focused on developing, commercializing, building and operating utility-scale solar plus battery storage projects in targeted US energy markets. Our mission is to create a sustainable future by providing clean, low-cost energy solutions to the grid benefiting energy consumers, communities, and generations to come. Treaty Oak is a wholly-owned portfolio company of Macquarie Asset Management (Macquarie), pairing Treaty Oak’s renewables development expertise with Macquarie’s capital backing.
Headquartered in Austin, Texas, Treaty Oak’s portfolio consists of 20 GW+ of in development and in construction utility scale renewable projects across the United States. Treaty Oak features an experienced management team with a track record of developing and commercializing 9 GW+ of utility-scale power projects and a collective 100+ years’ experience across critical competencies, including power markets, offtake structuring, design, engineering and real estate.
The Manager, Development Engineering is responsible for leading and managing technical engineering activities during the development, engineering, procurement, and pre-construction phases of utility-scale renewable energy projects, including solar photovoltaic (PV), battery energy storage systems (BESS), substations, transmission interconnections, and associated balance-of-plant infrastructure.
This position serves as the primary technical representative for assigned projects and is responsible for coordinating multidisciplinary engineering efforts with internal stakeholders, engineering consultants, EPC contractors, utilities, Independent Engineers (IE), Owner's Engineers (OE), equipment manufacturers, permitting agencies, and regulatory authorities. The role requires advanced engineering judgment, technical leadership, and extensive knowledge of power systems, renewable energy project development, and utility interconnection requirements.
The Manager, Development Engineering reports directly to the Senior Manager, Engineering and plays a critical role in ensuring projects progress from early development through construction with technically sound, commercially optimized, and schedule-driven engineering solutions.
Lead the engineering development of utility-scale solar PV, battery energy storage (BESS), substation, transmission line, and interconnection facilities.
Provide technical leadership throughout project development, detailed engineering, procurement, construction support, commissioning, and project closeout.
Evaluate engineering alternatives to optimize project cost, constructability, reliability, operability, maintainability, and long-term asset performance.
Manage multiple engineering consultants including Electrical Engineers of Record (EOR), Civil Engineers, Geotechnical Engineers, Surveyors, Environmental Consultants, Transmission Engineers, and Owner's Engineers.
Direct engineering deliverables through all project milestones including conceptual design, 10%, 30%, 60%, 90%, Issued for Construction (IFC), and Record Drawing phases.
Review engineering calculations, design reports, technical specifications, construction drawings, studies, and engineering documentation for technical accuracy and compliance.
Coordinate multidisciplinary engineering reviews across civil, structural, electrical, mechanical, controls, telecommunications, and SCADA disciplines.
Interconnection & Utility Coordination
Lead technical coordination with electric utilities, Independent System Operators (ISO), Regional Transmission Organizations (RTO), transmission owners, balancing authorities, and reliability coordinators.
Review interconnection studies including load flow, short circuit, transient stability, PSCAD, EMT, protection coordination, grounding, harmonic, reactive power, and dynamic model studies.
Coordinate utility witness testing, energization planning, commissioning activities, and commercial operation readiness.
Project Development Support
Evaluate site constraints including topography, hydrology, geotechnical conditions, environmental permitting, constructability, access, grading, drainage, and utility infrastructure.
Engineering Procurement Support
Lead engineering reviews for project documentation including:
Site layouts, Single-line diagrams, Electrical studies, Civil grading plans, Stormwater management, Hydrologic and hydraulic analyses, Structural calculations
Construction & Commissioning Support
Review Requests for Information (RFIs), Engineering Change Requests (ECRs), Field Change Notices (FCNs), and non-conformance reports.
Support commissioning, testing, energization, substantial completion, and commercial operation activities.
Regulatory & Technical Compliance
Ensure engineering compliance with applicable industry standards including but not limited to:
IEEE, ANSI, NEC, NESC, NFPA, ASCE, AISC, ASTM, NERC, FERC, State and Local Regulatory Requirements
Education and Qualifications
Minimum 6 years of progressively responsible engineering experience in utility-scale renewable energy, electric utilities, consulting engineering, EPC contracting, or power delivery.
Strong understanding of utility interconnection requirements, substation engineering, collector systems, transmission systems, power system studies, and renewable energy technologies.
Experience supporting projects within MISO, ERCOT, PJM, SPP, CAISO, NYISO, ISO-NE, or other North American transmission markets.
