Key Responsibilities

Support design development, project engineering, plan reviews, owner’s engineers, and construction of photovoltaic (PV), high voltage (HV), sub‑station, and grid‑scale battery energy storage systems (BESS) in coordination with the AES Business Development, Engineering and Construction teams and other markets. Provide expert technical support across solar PV, substation, HV, and battery storage projects and serve as the team’s subject‑matter expert for structural design.

Project

Development
  • Provide support for early‑stage foundation design options for project estimating purposes.
  • Collaborate with external engineering vendors to develop conceptual design approaches and tools for various foundation systems (e.g., piles, anchor systems, grade beams, helical foundations).
  • Support innovation and standardization of conceptual design methodologies across foundation types.
  • Review and occasionally provide preliminary structural designs for projects in early development.
  • Review of geotechnical reports for structural impacts on projects in development.
Project Execution
  • Support project engineering with external Owner’s Engineer (OE) engagements with SOW, vendor coordination, and reviewing proposals.
  • Support Project Engineers in procuring OE services and/or external services; ensure consistent, high‑quality reviews.
  • Support OE reviews as needed.
  • Provide technical input, design solutions, and reviews for structural deliverables identifying areas for value engineering (e.g., PV Racking, BESS, HV Substation and Gen‑Tie/Overhead line).
  • Review and comment on structural engineering calculations, studies and RFI’s across projects (e.g., design calculations, snow, wind, corrosion studies).
  • Review design packages for conformance with industry codes and standards, prudent industry practices, AES contractual technical specifications and AHJ requirements.
  • Perform site visits to assess structural issues during construction and operations.
  • Support or perform root‑cause analysis for structural issues.
  • Conduct Job Site Assessment (JSA) s and safety walks to identify job‑site hazards.
  • Coordinate with HV and project engineers to assess and provide recommendations to project schedules.
Engineering Support
  • Build and maintain a database of foundation designs (historical and current).
  • Analyze design evolution (e.g., steel tonnage from concept to IFC) to guide cost and design decisions.
  • Provide rapid, data‑backed material impact estimates for design changes.
  • Draft and update structural specifications to current industry practices and trends by incorporating lessons learned from past projects.
  • Verify structural calculations are complete and recommendations are incorporated into construction documents.
  • Support the Project Management and Engineering to troubleshoot issues during construction or operations and maintenance and develop repair/remediation options.
  • Support the Innovation team with product reviews related to structural design.
