Senior Thermal-Fluids Analyst - CFD & System Modeling

Antares; Los Angeles (CA); On-site; USD 120,000 - 180,000; Full time

Job summary

Antares, located in Torrance, CA, is seeking an Analyst to build and run thermal-fluid models of reactor components and subsystems to ensure designs meet thermal, mechanical, operational, and performance requirements in the extreme environments of the R1 micro-reactor. You will work with design engineers, support test campaigns, and develop internal tools while mentoring other engineers.

Strong CFD (Fluent/CFX/Star-CCM+) and CAD (NX) experience, plus scripting (Python, Matlab, VBA), are

Qualifications

• Bachelor's in Mechanical or Aerospace Engineering or similar technical discipline.
• 5+ years' experience performing thermal-fluid analysis.
• Experience building and running CFD models using Fluent, CFX, and Star-CCM+, including conjugate heat transfer models and compressible equations of state.
• Experience using CAD software for design modification and model defeaturing (Siemens NX or similar).
• Experience in Python, MatLab, VBA, or other scripting language to build and maintain tools and calculators.
• Master's in Mechanical or Aerospace Engineering or similar technical discipline (preferred).
• Familiarity with 1-D fluid network tools such as Flownex, Sinda-Fluint, or RELAP5.
• Participation in regulatory qualification or certification programs for safety-critical systems in the aerospace or nuclear industry.
• Understanding and experience implementing numerical methods to solve fluid-dynamic and thermodynamic systems.
• Experience working with multiphase fluid & heat transport systems (Heat Pipes, Rankine Cycle Engines, Saturated Cryogenic Storage).
• Familiar with ASME BPVC Section III Div 5.
• Experience building and running Finite Element Analysis (FEA) models.
• Comfortable in a fast-paced environment with rapid design iteration loops.

Responsibilities

• Assess subcomponent designs for pressure drop, heat transfer capabilities, and other performance characteristics using hand-calcs, in-house tools, and CFD.
• Collaborate with designers and responsible engineers to provide guidance on initial sizing, material selection, and design feedback based on analytical results.
• Compile detailed documentation of analytical results and communicate key results, assumptions, and limitations to stakeholders throughout the company and external customers.
• Provide support to test engineers in the form of collaborative test design, instrumentation selection, and data review to ensure test campaigns provide the necessary data to validate our models.
• Develop internal tools and calculators to enable other engineers to quickly and independently perform analytical assessments of their designs without the need for detailed finite element models.
• Provide technical mentorship and guidance to other engineers and across teams.
