About the role

The role will involve collaborating closely with other members of the Systems team in addition to Turbomachinery, Supply Chain, Manufacturing, Field Ops, and others.
The title of this role may be adjusted based on the candidate's qualifications and experience.

Develop and maintain system-level architecture for mechanical and fluid subsystems
Perform trade studies to evaluate mechanical configurations, flow architectures, and their impact on system performance and cost
Integrate components such as pumps, piping networks, valves, heat exchangers, and rotating machinery into the overall system design
Design structural support hardware for multiple components and sub-systems
Perform hand calculations using first principles to size components, determine flow rates, estimate stresses, etc.
Perform finite element analysis (FEA) to evaluate structural integrity of components and subsystems
Identify opportunities to optimize plant layout to increase construction efficiency, minimize cost, and improve maintainability
Assist in the development of test plans and instrumentation strategies to validate mechanical and fluid performance
Analyze experimental data to refine and improve system design
Generate technical documentation including system specifications, modeling reports, design trade studies, test analysis reports

Bachelor's degree in mechanical engineering or related field, or equivalent experience
5+ years of proven experience in systems engineering or highly related role, with a strong portfolio of projects involving diverse and integrated machinery
A solid understanding of and the ability to apply first principles of core mechanical engineering principles, including structural and fluid mechanics, thermodynamics, and material science
Experience with a modern CAD package and a willingness to immediately self-teach proficiency in Siemens NX
Experience with components and sub-systems common to power generation or process plants, like heat exchangers, pumps, turbines, valves, piping, fittings, sensors, and fluid management systems
Experience generating 3D models and managing assemblies in CAD while ensuring proper fit and function
Experience with FEA using commercial software (e.g., ANSYS Mechanical, NASTRAN, Catia)
You are effective and respectful in communicating with other engineers even when it is controversial or regarding errors that you have observed or have been observed in your work
Identify, outline, design, and support component-level and sub-system testing required for risk mitigation

Proven expertise in Siemens NX / Teamcenter environment
Experience with computational fluid dynamics (CFD) using commercial software (e.g., ANSYS CFX, ANSYS Fluent)
Hands-on experience with product development, such as resolving manufacturing issues and analyzing test data to inform design modifications

Experience specifically with power generation or process plant systems is not a requirement but is a significant bonus.
