Thermofluids & Thermal Hydraulics Engineer, Equipment Technologies

Hatch•West Mifflin, PA

About The Position

Hatch is seeking a Thermofluids & Thermal Hydraulics Engineer to join its Technologies team in the Pittsburgh area. The team commercializes and delivers technologies across the Metals, Energy, and Infrastructure sectors, providing custom engineering and specialized solutions. This role plans, executes, and delivers mechanical and process engineering work involving fluid flow, heat transfer, and mass transfer for heavy industrial projects, meeting scope, budget, schedule, and quality objectives. The engineer applies first-principles analysis, calculation tools, and numerical methods—including Computational Fluid Dynamics (CFD)—to assess transport phenomena and solve practical industrial problems. Work includes producing calculations, process-related deliverables, technical reports, and scopes of work; communicating findings to clients and engineering teams; and contributing to project decisions and business development. The role may also involve site visits and measurement campaigns, developing in-house numerical tools and models, and presenting technical papers at industry conferences. The successful candidate must be a U.S. Person or otherwise eligible to work on projects subject to 10 CFR 810.

Requirements

Bachelor’s degree in Mechanical, Process, Chemical, or a closely related engineering discipline from a recognized university.
Completed core coursework in fluid mechanics, heat transfer, and numerical methods with high standing.
Professional Engineer (PE/P.Eng.) licence or demonstrated progress toward licensure.
At least 3 years of progressive experience in mechanical, process, or chemical engineering.
Strong interest and capability in first-principles analysis and design, with demonstrated application of theory to practical problems through education or work experience.
Proficiency in scientific programming, such as Matlab, C++, Fortran, or Python.
Strong understanding of numerical methods such as finite-volume and finite-difference methods.
Critical thinking and ability to develop effective solutions to complex problems.
Ability to manage assigned work independently, collaborate effectively, and meet quality, cost, and schedule commitments.
Strong written and verbal communication skills, including the ability to explain complex technical concepts clearly to colleagues and clients.
Must be a U.S. Person (U.S. citizen, U.S. lawful permanent resident, refugee, or asylee) or otherwise eligible to work on projects subject to 10 CFR 810.

Nice To Haves

Experience in heavy industry.
Coursework in transport phenomena, finite-volume methods (CFD), combustion, multiphase flows, aerodynamics or hydrodynamics, compressible flows, or thermodynamics.
Proficiency and experience with commercial CFD software such as Ansys Fluent, Siemens STAR-CCM+, or equivalent.
Proficiency with commercial 1-D flow network software such as Flownex or Arrow.
Working knowledge of relevant codes and standards; experience with NFPA, ventilation standards such as ASHRAE, and/or nuclear-industry-related codes such as NQA-1 is highly desirable.
Interest in client engagement and business development, with the ability to contribute to proposals and project pursuits.

Responsibilities

Plan, execute, and deliver mechanical and process engineering work involving fluid flow, heat and mass transfer for heavy industrial projects, meeting scope, budget, schedule, and quality objectives.
Apply first-principles approaches, calculation tools, and numerical methods including CFD to solve fluid-flow and heat-transfer problems.
Assess transport phenomena, including multiphase flows, porous-media flows, conjugate, convective, and radiative heat transfer, phase-change heat transfer, chemical reactions, and mass transfer.
Prepare calculations, process-related deliverables such as contributions to mass and energy balances and process flow diagrams, technical reports, and scopes of work.
Collaborate with multidisciplinary teams across regions and offices to develop and deliver solutions for clients.
Communicate analysis and assessment results to engineering teams and clients, participate in design decisions, and guide project-team decision-making.
Engage with clients to understand technical needs, communicate findings, and build working relationships.
Support business development through proposal preparation, client meetings, project pursuits, and contributions to technology-development initiatives.
Perform site visits and measurement campaigns on some occasions.
Develop in-house numerical tools and models.
Write and present technical papers at industry conferences.
