Overview
At PNNL, our core capabilities are divided among major departments that we refer to as Directorates within the Lab, focused on a specific area of scientific research or other function, with its own leadership team and dedicated budget.
Our Science & Technology directorates include National Security, Earth and Biological Sciences, Physical and Computational Sciences, and Energy and Environment. In addition, we have an Environmental Molecular Sciences Laboratory, a Department of Energy, Office of Science user facility housed on the PNNL campus.
The National Security Directorate (NSD) drives science-based, mission-focused solutions to take on complex real-world threats to our nation and the world.
The Nuclear, Chemical, and Biological Technologies Division, within the National Security Directorate, works across fundamental science, research and development, and operations to counter emerging national security threats. We focus on discovering signatures and understanding threats by creating materials, methods, and technologies to detect and analyze them. Our researchers deliver the solutions necessary for addressing complex mission challenges, such as explosives detection, biological threat detection, chemical and nuclear forensics, and special nuclear materials.
Responsibilities- Key responsibility is to work with internal stakeholders and external sponsors to serve as a subject matter expert (SME) to create concepts and execute strategies to develop advanced space nuclear reactor technologies as well as counter national security threats related to space and nuclear technologies.
- Key responsibility is to lead project teams to execute project work related to space nuclear reactor technologies.
- Work on complex engineering topics where analysis of unique situations and data requires an in-depth evaluation and assessment of a variety of dynamic factors. Exercise judgement in selecting strategy approaches, methods, techniques, and criteria that will generate the optimum solution and results.
- Maintain an understanding and knowledge of key project issues and initiatives that will allow for proposing improvements and expanding the project portfolio.
- Provide expertise in core engineering topics with strong analytical thinking and excellent verbal communication skills related to topics such as nuclear material processing; material science; heat transfer; fluid mechanics; radiation transport, detection, and measurement; radiation hardening, reactor design, advanced manufacturing, modeling and simulation, and experimental testing.
- Maintain effective working relationships with other research staff, project managers, and stakeholders. Develop positive influence across project interest groups and external organizations and partners to move engineering concepts forward to viable solutions.
- Recommend innovative designs and strategies that can be applied to meet project goals. Author technical white papers and proposals, technical documentation, invention reports, and analyses describing related technological advances in assigned areas of expertise.
- Maintain interactions with and facilitate collaboration among a diverse set of multi-disciplined PNNL and external teams. Frequent communication with project points of contact is expected and required, with the ability to effectively interface with others to develop solutions and capabilities that will accomplish project missions.
- Support occasional travel to interact with project sponsors and external collaborators.
- Appropriately handle non-sensitive, sensitive, and classified information as required by the assigned project topics.
- The incumbent must demonstrate an ability to manage sensitive information while influencing positive outcomes. The person in this position must recognize and accept that they will be working in technical areas associated with the National Security of the United States.
