Job summary

Nano Nuclear Energy, Inc. seeks a Fuel Ceramic Engineer in Oak Ridge to lead ceramic body and pellet fabrication process development for advanced nuclear fuel.

You will own processes, work with materials and equipment, and collaborate with coating, qualification, and characterization teams to scale methods from lab to production. The role emphasizes hands-on experimentation, scale-up, and cross-functional collaboration to ensure material properties, TRISO integrity, and process reliability as

Qualifications

• Experience in advanced ceramics, ceramic composites, nuclear fuel, powder processing, high-temperature materials, or comparable manufacturing.
• Hands-on experience preparing ceramic materials, operating fabrication or thermal-processing equipment, and troubleshooting experimental processes.
• Strong knowledge of ceramic processing, densification, microstructure, dimensional control, and defect mechanisms.
• Ability to connect process parameters with material properties and translate laboratory methods into controlled pilot or production-intent processes.
• Strong technical writing, experimental planning, problem-solving, and cross-functional communication skills.

Responsibilities

• Develop and optimize ceramic feedstocks, powders, binders, forming methods, thermal processing, densification, and finishing.
• Establish process parameters and controls to achieve target material properties, dimensions, and TRISO particle distribution while minimizing defects.
• Execute fabrication campaigns, operate equipment, troubleshoot processes, and evaluate material performance.
• Investigate manufacturing defects and implement improvements to process consistency, quality, and yield.
• Develop scale-up strategies for progressing from laboratory fabrication to pilot and production-representative manufacturing.
• Maintain technical records, process traceability, and characterization data to support fuel qualification.
• Coordinate with multidisciplinary teams to align fabrication processes with downstream coating and qualification requirements.
