Job Description

Job Summary

Kairos Power is seeking a highly motivated Nuclear Engineer to join our Nuclear Design and Methods team and assist in choosing, designing, and testing radiation detection instrumentation for Kairos’ Hermes test reactor and FHRs. We are seeking a candidate with a solid technical background in radiation transport, detection, instrumentation, and dosimetry. The ideal candidate will have experience in modeling, setting up, and testing radiation detectors through working in nuclear facilities (preferably test and research reactors), collecting and analyzing radioactive samples following appropriate ANS/ANSI/HPS standards, and performing worker dose calculations.

Responsibilities

• Support the development and deployment of radiation detection instrumentation for various projects through iterative design loops (design, build, and test).
• Develop and maintain the area, effluent, and environmental monitoring programs, including scope and specification of instrumentation, and work closely with the relevant stakeholders across the company (Licensing, Ops, etc.) to incorporate design needs into the monitoring programs.
• Work with relevant stakeholders in support of Hermes’ Final Safety Analysis application.
• Perform calculations of worker dose across the plant to ensure maintaining ALARA.
• Engage with external vendors and testing labs as necessary.
• Other duties as assigned.

Qualifications

• MS or PhD in Nuclear Engineering with a focus on radiation detection or health physics.
• Experience after graduation in research reactor facilities or similar research environments is preferred.
• Experience with designing and setting up detector characterization tests.
• Experience with semiconductor detectors (HPGe and CZT).
• Experience with digital signal processing techniques and instrumentation.
• Experience with gamma spectroscopy.
• Experience with detector response modeling software such as GADRAS-DRF.
• Experience with variance reduction techniques (weight windows, source biasing, etc.) and software (Attila4MC and/or ADVANTG).
• Familiarity with CAD design software (SolidWorks and/or SpaceClaim).
• Experience with applying ML/AI in radiation detection applications.

Physical Conditions

• Remaining in a stationary position, often standing or sitting for prolonged periods.
• Ability to carry up to 50 pounds.

Travel

• Up to 30% of domestic travel may be required.

Safety and PPE

• Reading and interpreting hazardous warning signs.
• Reporting issues with equipment or unsafe conditions.
• Wearing proper PPE, including face masks, face shields, gloves, and safety shoes.
• Occasionally work with lead sheets/bricks.

Additional Requirements

• Occasionally requires schedule flexibility.
• Occasionally requires extended hours to support launch and critical project timelines.
