Senior Heat Exchanger Design Engineer

53 Stations; Los Angeles (CA); On-site; USD 140,000 - 185,000; Full time

Job summary

Antares is seeking a Senior Thermo-Mechanical Design Engineer to develop and qualify heat exchanger systems for advanced energy applications. You will work with Responsible Engineers and multi-disciplinary teams from concept through production to deliver high-performance, reliable hardware.

The role requires strong fundamentals in thermal and mechanical design, experience with CAD and analysis tools, and a track record in heat exchanger and piping design for high-temperature environments.

Qualifications

• Bachelor's degree in Mechanical Engineering, Aerospace Engineering, Nuclear Engineering, or a related physics-based field.
• 5+ years of experience in mechanical or thermal engineering, preferably involving heat exchangers, pressure-containing equipment, or high-temperature systems.
• Demonstrated experience with mechanical CAD design and engineering analysis tools (e.g., SolidWorks, NX, ANSYS, COMSOL).
• Understanding of heat transfer fundamentals, fluid mechanics, thermal stresses, and structural mechanics.
• Understanding of piping and pressure-containing component design, including pressure loads, thermal expansion, and mechanical interfaces.
• Knowledge of materials science as it applies to material selection, thermal properties, and structural performance.

Responsibilities

• Perform mechanical design, modeling, and analysis of heat exchanger systems, ensuring thermal performance, structural integrity, and compatibility with system interfaces.
• Design and analyze heat exchanger inlet/outlet piping, manifolds, and associated mechanical interfaces, ensuring compatibility with system performance and installation requirements.
• Evaluate thermal stresses, differential thermal expansion, pressure loads, piping flexibility, and mechanical loads transmitted between heat exchangers, piping and supporting structures.
• Support development of manufacturing methods, including material selection, fabrication processes, joining techniques, and assembly of heat exchanger and piping components.
• Design and support development of test articles, test stands, and procedures to validate thermal performance, structural integrity, and operational life.
• Coordinate with internal teams and external stakeholders to translate system requirements into manufacturable and reliable hardware products.
• Support the design and integration of piping connections, flanges, weld joints, supports, and other fluid-system components, considering manufacturability, assembly, inspection, and maintenance.
• Define operating limits and performance envelopes for heat exchanger systems.
• Investigate hardware failures, identify root causes, and rapidly implement design improvements to enhance performance and reliability.
