About the Role Fermilab is seeking a Senior Mechanical Thermal‑Fluids Engineer to lead the Thermal‑Fluids Engineering Group. The lead is a collaborator by nature and seeks out the latest technology and tools to design, fabricate, test, install and operate components and systems for our particle accelerators. We use the latest technology such as ANSYS, NASTRAN, Siemens NX, and additive manufacturing (3D printing) to model, simulate, prototype, and test our designs. We work with vendors who stretch their technical abilities to fabricate the next generation of components and systems. We expand our engineering skills and, sometimes, write the textbooks to operate the existing accelerators. We work with collaborators throughout the lab and the world to plan future accelerators for projects such as the Long Baseline Neutrino Facility (LBNF) and Proton Improvement Plan II (PIP‑II). Day‑to‑Day Responsibilities Serve as the Thermal‑Fluids Engineering Group leader. Serve as the Level 4 Technical Manager for the LBNF RAW Water Systems. Utilize fundamental mechanical engineering concepts and principles to complete assignments and develop familiarity with the laboratory’s method of project engineering, from the design stage through review, procurement, fabrication, installation, test, and operation. Be involved in the mechanical design, analysis, specification, and construction of fluid cooling piping systems that support the operation of the accelerator complex, including the temperature control of beamline components (such as magnets, collimators, RF cavities, beam instrumentation, high‑powered targets, kickers, and associated beam components). Participate in and lead efforts involving general mechanical‑system design, thermal‑fluid system design, piping system fluid flow analysis, and heat transfer analysis. Learn the operations of existing accelerator fluids systems and provide operations engineering support by troubleshooting system issues and designing upgrades to existing systems to improve their reliability. Participate in the design of compressible and incompressible thermal fluids systems to support the accelerator. Fabricate systems using different types of welding, brazing, bonding, and soldering techniques with materials such as aluminum, stainless steel, copper, brass, PVC, CPVC, PVDF, etc. Work in a team environment. Be responsible for directing the activities of drafters, designers, technicians, and skilled trades on their projects. Communicate with outside vendors, contractors, and fabricators through written specifications and engineering drawings. Direct the activities of co‑op engineering students and interns on their projects. Abide by and be responsible for performing all duties in accordance with all environmental, health and safety regulations and practices pertinent to this position.
