Job Summary

The Mechanical Engineer Principal will support gas, coal, and renewable plant retrofit and new-generation self-build projects by defining mechanical design-basis expectations and supporting technical specifications, engineering, and procurement of rotating and static equipment, piping, structures, and balance-of-plant systems. A required focus of this role is advanced knowledge of natural gas simple cycle and combined cycle equipment, systems, and power plant configurations (combustion turbines, HRSG, steam turbines, balance-of-plant integration, heat recovery systems, and auxiliaries).
This role collaborates with Architect & Engineering (AE) and Engineer, Procure and Construct (EPC) firms and coordinates with internal and external stakeholders to ensure mechanical designs meet performance, reliability, constructability, safety, and regulatory requirements. The engineer will participate in RFx/OEM engagements, support self-build proposals, and provide construction, commissioning, and lifecycle support.

Job Description

What you’ll do:

Key Responsibilities

• Develop and document mechanical design basis and requirements for plant equipment, including turbines, generators, HRSGs/boilers, heat exchangers, pumps, compressors, cooling systems, piping, and structures.
• Apply advanced knowledge of simple and combined cycle gas turbine plants to equipment selection, system integration, and performance evaluations.
• Work with AE and EPC teams to review, comment on, and approve mechanical designs, drawings, and engineering calculations.
• Prepare and review technical and procurement specifications, scope documents for self-build proposals, and RFx deliverables.
• Interface with OEMs during RFx and procurement to confirm technical compliance, lead times, warranties, and vendor submittals.
• Support vendor evaluation and bid reviews, focusing on turbine/HRSG interfaces and steam cycle integration.
• Provide construction, commissioning, and startup support: site inspections, punch list resolution, and troubleshooting.
• Perform or review analyses as required (stress, vibration/rotor dynamics, thermal, piping flexibility, fatigue) to validate designs.
• Ensure compliance with applicable codes and standards (ASME, API, ANSI, NFPA, IEEE, local codes) and lead reliability/FMEA/RCM and obsolescence mitigation activities.
• Coordinate with electrical, I&C, civil, and operations stakeholders and support development of O&M documentation, spare parts lists, and lifecycle cost assessments.
• Promote safe design practices and ensure adherence to site-specific safety requirements.

Knowledge & Skills

• Deep understanding of turbomachinery performance, rotor dynamics, vibration analysis, alignment, and balancing.
• Competence with piping stress analysis, pipe supports, and expansion management in high-temperature HRSG/steam systems.
