Headquartered in the San Francisco Bay Area, Energy Recovery has manufacturing, research and development facilities across California and Texas with sales and on-site technical support available globally. For more information, please visit www.energyrecovery.com. What You Can Look Forward To: What You Will Do: Support R&D projects (New Technology and New Product) involving fluid machines such as pressure exchangers, centrifugal and reciprocating pumps, turbines, turbochargers etc. Develop analytical and CFD models to analyze turbomachinery and fluid machinery designs, suggest ways to optimize designs and predict performance over the full operating envelope. Leverage commercial CFD tools such as ANSYS CFX/Fluent and/or STAR-CCM+ to generate computational meshes, perform CFD analyses and postprocess results. Build 1-D steady-state and transient fluid system models using tools such as Simscape, GT-SUITE, Simcenter Flomaster or equivalent to analyze and optimize machine and system performance. Help develop validation test plans and work closely with testing teams to confirm and validate model predictions. Use commercial and open-source software to process test data and draw physics-based insights and inputs for models. Help develop validated semi-empirical performance models of ERI products for use by engineering, sales, and customers. Participate in the development cycle of a fluid machine including 1-D hydraulic sizing, engineering analyses, design reviews, experimental validation, RCAs & release to manufacturing. Collaborate with multi-national, cross-functional teams across time zones. Follow ERI’s structured, phase-gated development process, contributing to design reviews and documentation at each phase. Contribute to the development of validated design tools and design practices. Other duties and projects as assigned. What You Bring to the Table: Bachelor's degree in Mechanical or Aerospace Engineering (or related discipline) with 2+ years of relevant industry experience, or a Master's degree with 1+ years of relevant industry experience, required. Concentration in mechanics of fluids highly desirable. Strong background in fluid mechanics and fluid machinery required. Hands-on experience in commercial CFD solvers such as ANSYS CFX/Fluent or STAR-CCM+ required. Experience with 1-D fluid flow / system modeling tools such as Simscape, GT-SUITE or equivalent is highly desirable. Experience modeling turbomachinery such as pumps, turbines, compressors or fans required. Experience with product development of fluid machines a plus. Familiarity with CAD packages such as SolidWorks/Onshape/Creo/NX/CATIA and programming/scripting (Python, MATLAB) desirable. Proficiency in using AI tools to accelerate engineering work (e.g. research, scripting/automation, data analysis, documentation), with sound engineering judgment to verify AI-generated results, is a plus. Graduate-level coursework in fluid mechanics, CFD and turbomachinery highly desirable. Must possess a demonstrated ability to work in a team environment, manage multiple tasks, and be goal oriented. Excellent written and verbal communication skills. Must be willing to work from ERI's India office once it is established; the role will be remote until then. Regular overlap with US Pacific time, typically 2-4 hours in the IST evening, in-office workday adjusted accordingly. Position may require up to 5% travel, including international travel.
