Pre-NTP Mechanical Engineer

About the role

AES Indiana is developing and building several generation projects to meet increasing demand driven by data center growth. The immediate focus is the technical development of at least one CCGT power plant (~650 MW), with a second CCGT likely. Additional generation projects will bridge demand until the first CCGT comes online in 2033/2034. The Pre-NTP Mechanical Engineer will manage the mechanical design of these projects, working within the Generation Development Team to develop Technical Specifications and EPC Contracts, leveraging Owner’s Engineers and consultants. This role may evolve into a Mechanical Engineering or Project Engineering Manager position during project execution.

Responsibilities

• Provide safety leadership for all aspects of the project.
• Develop the mechanical design for the projects, including:
  • Review and selection of major equipment (gas turbines, steam turbines, rotating equipment).
  • Review of process flow diagrams and piping design.
  • Review of all mechanical interfaces (e.g., gas and water interconnection requirements).
  • Review of steam, water, and chemical storage and delivery systems.
  • Review of internal water treatment and disposal systems.
  • Ensure overall project performance aligns with AES Indiana’s commercial expectations.
• Develop, review, and collaborate with Owner’s Engineers and SMEs on mechanical design details in Technical Specifications.
• Review mechanical design for operational consistency and adherence to AES Indiana standards.

Requirements

• BS or equivalent degree in mechanical engineering or a relevant technical field.
• 5–10 years of experience in technical design (operational experience preferred), including large CCGT and other generation projects.
• Ideal candidate has construction and commissioning experience for conventional (fossil fuel) generation projects.
• Experience reading and understanding project schedules and principles.
• Minimum of 5 years’ electrical design and/or construction experience.
• Exceptional written and oral communication skills.
• Proficiency in applicable electrical codes and standards for large power generation projects.
