About the role

About the Role

As a Materials Engineer you will aid in the development and qualification of all materials in Antares’ reactor systems. This will consist of developing experiments, processes, and quality control as well as working with vendors and collaborators to identify and rectify critical gaps in material behavior at our operating conditions. This position requires the ability to learn quickly and develop a deep understanding of a wide range of materials – including ceramics and metallic alloys – such that you become the go-to subject matter expert at the company. The ideal candidate will apply fundamental knowledge of materials science to the practical applications of manufacturing in a fast-paced environment while also pushing innovation for the next generation of materials – driving Antares to be a recognized leader in nuclear materials.

Roles & Responsibilities:

  • Partake in the development and qualification for all materials in the reactor, including lifetime testing, cross-institutional collaboration, and property evaluation.
  • Design and conduct physical, thermal, and mechanical testing of materials that replicates the reactor environment.
  • Employ statistical methods to systematically evaluate effects of process variables and environmental effects on materials properties.
  • Materials characterization including root cause investigations of failure modes.
  • Interface with manufacturing, neutronics, mechanical, testing, and quality engineers to integrate materials into the overall system, define limits to operating conditions based on material properties, and optimize processes.

Basic Qualifications:

  • Bachelor’s degree in Mechanical Engineering, Materials Engineering, or a related field.
  • 2+ years of experience in materials engineering.
  • Experience with Metals
  • Proficiency in optical and electron microscopy as well as mechanical property evaluation.

Preferred Skills and Experience:

  • 3+ years demonstrated experience as part of integrated team in a production setting.
  • Knowledge of radiation effects in materials.
  • Knowledge of stainless steel, Ni based superalloys, and ceramics.
  • Coatings experience.

Additional Requirements:

  • Ability to work long hours and weekends as necessary to support critical milestones.
