Job Description:

Idaho Power — located in Mountain Home, Idaho — is looking for a Senior Engineer to join our Power Production Engineering and Resource Development team as a Thermal Engineer supporting the design, construction and performance of our gas turbine and/or reciprocating engine generation fleet. It’s an exciting time to work for Idaho Power. Our work plays a critical role in communities we serve across Idaho and Oregon, and we’re working hard to provide our customers with safe, reliable, and affordable energy they depend on.

 

What does a Senior Engineer do for us?

This role plans and leads moderately complex assignments and projects, interfaces with internal departments and external organizations, and receives high-level guidance from leaders and other engineers as needed. With a focus on thermal generation, this engineer monitors, analyzes, and improves the performance, efficiency, and reliability of reciprocating internal combustion engines (RICE), combined-cycle, and simple-cycle gas turbine plants.

 

Key responsibilities include:

• Supporting the design and construction of new RICE and simple-cycle gas turbines.
• Tracking and trending key performance indicators such as heat rate, output, efficiency, availability, vibrations, and emissions for RICE and gas turbines
• Planning and conducting performance testing, including pre- and post-outage testing, to evaluate degradation and validate maintenance and upgrade results
• Analyzing plant historian and control system data to identify performance losses, root causes, and improvement opportunities
• Supporting outage planning, inspections, and condition assessments in coordination with plant operations, maintenance, and original equipment manufacturers (OEMs)
• Providing technical input on capital projects, upgrades, and future thermal generation development

 

In addition to the meaningful work we do, we offer work-life balance, competitive pay and benefits, an employee incentive plan, and both a 401k employer-match and a pension plan, making Idaho Power one of the best employers in the state.

 

A COMPETITIVE CANDIDATE WILL HAVE

Knowledge of:

• Engineering principles
• Moderate degree of specific knowledge related to thermal performance
• Utilities and their business environment
• Reciprocating engine, gas turbine, and combined-cycle operation, performance, and maintenance practices
• Thermodynamics, including Brayton, Otto and combined-cycle (Brayton–Rankine) power cycles and heat rate analysis
• Heat transfer and fluid mechanics as applied to power generation
• Power plant design principles and construction practices

Skills in:

• Interdisciplinary skills
• Effective oral and written communication
• Proficient use of computers and software related to position
• Performance testing, data trending, and use of plant historian and performance monitoring tools
• Heat rate, output, and degradation analysis, including correcting performance results to reference conditions
• Thermal performance modeling and data analysis tools (e.g., PI System, Thermoflow, Excel/Power BI)
• Vibration and dynamics analysis
• Root cause analysis and condition monitoring for thermal power plant equipment
• Cost-benefit analysis to support maintenance, upgrade, and capital project decisions
• Construction inspection

Ability to:

• Manage and coordinate projects of increasing complexity
