Job description

Step into a pivotal scientific leadership role where your expertise in external dosimetry drives Canada’s radiation health research forward. Can you see yourself leading a growing team, shaping cutting‑edge work in radiation metrology, and developing advanced irradiation facilities that enable real scientific impact? In this role, you’ll guide high‑impact computational and experimental R&D while collaborating with top universities, government partners, and industry to solve real‑world challenges in radiation science. If you’re ready to make a measurable difference in understanding biological responses to ionizing radiation and supporting critical national dosimetry services, this is where your work will matter most. Apply today.

What will you be doing!

• Providing scientific Leadership of research initiatives and generating new research project proposals with appropriate resourcing and budgeting.
• Collaborating with CNL colleagues to provide and characterize the irradiation facilities required for biological studies and other variations of research projects.
• Providing expert scientific advice within the company and to external clients.
• Identifying emerging market opportunities and supporting project execution.
• Ensuring the legislative and legal requirements of the Biology Research and Development Facility (BRDF) irradiation facilities are met by providing support when identified.
• Planning and conducting research in areas relevant to radiation effects, dosimetry and risk assessment, and novel detection metrology.
• Proactively working with business development to identify opportunities and lead R&D activities for new applications.
• Identifying and liaising with researchers and the BRDF branch manager to address gaps in capability (personnel and equipment).
• Evaluating and quantifying exposure (inanimate objects) and dose (for biological samples) using dose calculation software for research projects, where necessary, as a subject Matter Expert.
• Collaborating with colleagues in Canadian Universities to develop and undertake dosimetry and instrument‑related research projects funded by the Federal S&T program, the CANDU Owners Group and other organizations.
• Developing the skills necessary to provide an extra resource for dose assessments in support of CRL Dosimetry Services.
• Assisting the BRDF branch manager and team on the development and implementation of a multi‑user program for all BRDF facilities, allowing use of these CNL assets by university collaborators and other requestors.
• Assisting the Facility Authority (FA) and the BRDF branch manager in the development of the HPNG as a secondary standard laboratory.
• Providing input to the Isotopes, Radiobiology, and Environmental (IRED) directorate on strategic equipment capabilities and personnel skill sets.
• Acting as a resource and Subject matter expert (in the field of radiation dosimetry) for CNL.
• Other duties as assigned by your manager.

What we are looking for:

• Education
  • A PhD in Physics, or relevant discipline (i.e., radiation physics, applied nuclear physics, health physics or medical biophysics) from a university of recognized standing.
• Experience
  • Minimum of 8 years of relevant experience in radiation physics, health physics, modelling, or radiation sciences.
  • Experience with modelling techniques, including MCNP (desirable).
  • Experience managing or utilizing multi‑user radiation facilities.
  • Experience developing and evaluating radiation‑detection instrumentation, including demonstrated use of Monte Carlo codes for neutron transport and neutron‑scattering problem solving.
  • Experience with experimental measurement techniques involving radiation sources and radiation measurement instruments.
• Knowledge, Skills & Abilities
  • Demonstrated ability to publish scientific research as lead or senior author in peer‑reviewed journals.
  • Proven ability to produce research outputs suitable for peer‑reviewed publication.
  • Strong oral and written communication skills, with the ability to convey complex scientific concepts to multidisciplinary teams and non‑expert stakeholders.
  • Ability to effectively interact with staff at all levels—technical, management, and clients—to meet operational objectives.
  • In‑depth understanding of particle physics, including neutrons, protons, and heavy ions, and their quantification.
  • Strong understanding of ionizing radiation interactions (low‑ and high‑LET) with living matter and dose deposition (asset).
  • Proficiency with radiation‑measurement instrumentation and experimental techniques.
  • In‑depth knowledge of statistics and mathematics, and the ability to create, write, and read computer programs for data production, analysis, and interpretation, as well as for computational dosimetry model development.
  • Knowledge of radiation principles and the concept of dose for external exposures.
  • Knowledge of secondary standards laboratories and irradiation facilities, including relevant regulatory responsibilities.
  • Ability to lead and grow a research team, provide expert scientific advice, identify emerging market opportunities, and support commercial project execution.
  • Understanding of neutron detection instrumentation, including the ability to evaluate or develop detection systems.
  • Ability to use or learn dose‑calculation software to support and expand the organization’s dosimetry capabilities.
  • Familiarity with multi‑user facility frameworks (asset).
• Security Clearance Eligibility Required
  • Reliability Status with Site Access Security Clearance (SASC), which has a minimum requirement of 3‑5 years of verifiable history in Canada, Australia, New Zealand, the United States and/or the United Kingdom. CNL implements security screening in accordance with the Treasury Board of Canada Secretariat's “Standard on Security Screening” and the “Policy on Government Security.”

Working Conditions:

• Office and laboratory setting, involving radiological materials and devices and licensed nuclear facilities, thus some other areas where the position will work are Controlled.
• It is not expected, but if required, the position will be required to conform to dosimetry bioassay procedures for radionuclide intakes.
