Role Summary The Principal Mechanical Engineer provides senior-level technical leadership for the design, development, and sustainment of complex valve and actuator products. This role may be based at a Flowserve site such as Houston, TX; Cookeville, TN; Vernon, CA; or Lynchburg, VA, and for highly qualified candidates, remote work may also be considered. The position focuses on advanced mechanical design, CAD modeling, casting and forging development, engineering documentation, and manufacturability. It supports engineered‑to‑order programs, product development, sustaining engineering, configuration control, and continuous improvement. The role requires close collaboration with manufacturing, quality, supply chain, project management, purchasing, and field service to resolve technical issues and ensure robust product performance. Success in this role means becoming a trusted technical leader on complex valve engineering challenges while delivering designs that improve performance, manufacturability, and cost effectiveness. It also involves strengthening collaboration across cross‑functional teams, helping standardize best practices, improving engineering execution, mentoring less experienced engineers, and elevating the overall technical capability of the organization. Responsibilities Lead the mechanical design and development of complex valve and actuator assemblies, including engineered-to-order and custom application solutions. Provide technical leadership for 3D CAD modeling, detailed drawings, design layouts, and manufacturing documentation. Develop and review castings, forgings, machined components, and sub-assemblies to meet performance, reliability, and manufacturability requirements. Interpret customer specifications, internal standards, and applicable industry codes to develop practical and robust engineering solutions. Serve as a principal reviewer for design packages, engineering change notices, and product configuration updates. Develop and apply advanced engineering analysis techniques to solve challenging structural and flow problems. Master advanced engineering processes including FEA and CFD. Partner with engineering, manufacturing, purchasing, planning, quality, project management, and field service teams to resolve product-related issues. Drive sustaining engineering efforts to improve product reliability, manufacturability, cost, and compliance. Lead or contribute to continuous improvement initiatives and engineering process improvements. Author or co‑author white papers furthering industry knowledge and solidifying Flowserve’s position as a technical leader in the industry. Submit papers to relevant shows for presentation consideration. Mentor and guide less experienced engineers in design practices, drawing standards, and technical problem‑solving. Communicate effectively with internal and external stakeholders across global teams. Perform additional technical assignments and special projects as needed. Requirements Bachelor of Science in Mechanical Engineering or a related engineering discipline. 10+ years of progressive mechanical design experience, preferably in valve, actuator, or related industrial equipment environments. Advanced SolidWorks expertise, including complex part and assembly modeling. Strong knowledge of drafting practices and dimensioning standards based on ASME Y14.5. Proven ability to create and modify 3D parts using surfacing and advanced modeling techniques. Strong understanding of mechanical design principles, material compatibility, and product configuration control. Demonstrated ability to lead technical problem‑solving efforts in a fast‑paced engineering environment. Excellent verbal and written communication skills. Ability to collaborate effectively with a global team. Self‑starter who can work independently with minimal supervision while influencing cross‑functional teams. Preferred Master’s or Doctorate Engineering degree. Experience with ANSYS tools, including CFD and FEA. Background in casting and other valve manufacturing methods. CSWP certification. Familiarity with applicable ASME, ANSI, and MSS standards. Prior experience with valve products and ASME B16.34. Knowledge of Lean Manufacturing and continuous improvement methods. Experience supporting highly engineered or highly regulated product lines.
