Senior Mechanical Engineer - Thermo/Fluid Systems
SI Solutions, LLC, San Jose, California, United States, 95199
Structural Integrity Associates (SIA) is seeking a Senior Mechanical Engineer with expertise in thermo-fluid systems to join our Energy Services Group within the Turbine Generator Services team. This role is a senior individual contributor position, providing technical leadership in advanced engineering analysis, condition assessment, reverse engineering, and lifecycle evaluation of steam and gas turbine systems and associated components.
The position requires deep experience in turbomachinery thermo-fluids engineering and familiarity with major OEM steam and gas turbine platforms. The successful candidate will apply advanced analytical methods, including Digital Twin development, to support performance evaluation, failure mode assessment, remaining life estimation, and inspection planning. The role involves close collaboration with project managers, senior technical staff, and multidisciplinary teams, along with periodic travel to power generation facilities for field support and data collection.
Responsibilities and Qualifications Technical
Perform advanced thermal and structural stress analyses of turbomachinery components, gas and steam turbine rotors, and auxiliary equipment using classical methods and finite element analysis tools such as ANSYS and Abaqus
Develop and apply system and component level thermo-fluid and performance models for steam and gas turbines, including Digital Twin models (AxStream) for predictive analytics and lifecycle management
Conduct ASME Code evaluations and ensure compliance with applicable industry standards and best practices
Utilize thermo-fluid simulation tools (e.g., AxStream, ANSYS Fluent, STAR-CCM+) to evaluate flow behavior, operating conditions, performance characteristics, and generate boundary conditions for subsequent Thermo/Structural analysis and remaining life assessment.
Support nondestructive examinations and condition assessments, including metallurgical replication, hardness testing, ultrasonic inspection, and related techniques
Provide technical input for failure investigations, root cause evaluations, and remaining life assessments
Prepare clear, well-structured technical reports and client-facing presentations summarizing analyses, findings, and engineering recommendations
Contribute to internal research and development initiatives focused on automation, AI-enabled methodologies, and continuous improvement of analysis techniques
Business
Support project managers in the execution of complex, multi-disciplinary engineering projects
Lead or independently manage technical tasks and small-to-moderate scale projects as appropriate
Ensure technical quality through peer review, documentation, and adherence to internal standards
Maintain financial responsibility and comply with company guidelines related to project execution, expenses, and scheduling
Project Management
Support project managers in the execution of complex, multi-disciplinary engineering projects
Lead or independently manage technical tasks and small-to-moderate scale projects as appropriate
Ensure technical quality through peer review, documentation, and adherence to internal standards
Maintain financial responsibility and comply with company guidelines related to project execution, expenses, and scheduling
Travel and Working Conditions
Approximately 25% travel annually, primarily associated with power plant outage seasons (spring and fall), field inspections, and reverse engineering activities at client or SIA facilities
Occasional field work in operating power plant environments, which may include exposure to heat, noise, and confined space
Ability to comply with annual respirator fit testing and drug-free workplace requirements
Education and Experience
Bachelor or Master degree in Mechanical Engineering or a related discipline
7–10 years of progressive experience in turbomachinery engineering, including steam and gas turbine design, analysis, or field engineering
Proficiency in finite element analysis (FEA) tools (e.g., ANSYS, Abaqus) and thermo-fluid simulation software
Strong understanding of turbomachinery operation, thermodynamics, fluid mechanics, fracture mechanics, fatigue, and finite element methods
Advanced computer skills, including Microsoft Excel; experience with Mathcad, SQL, and scripting (VBA or similar) is a plus
Excellent analytical, problem-solving, and written and verbal communication skills
Professional Engineer (PE) license preferred or willingness to pursue licensure
This position could be re-coded for a suitable candidate with more experience and subject matter expertise
Pay Range The expected salary range for this role is $113,670 - $153,800 in San Jose, CA; $96,930 – $130,100 in Denver, CO. Exact pay will be commensurate with experience and location.
