Radiation Transport and Detector Scientist 2​/3

** What You Will Do*
* ** This position will be filled at either the 2 or 3 level, depending on the skills of the selected candidate. Additional skills are required if the candidate is hired at a higher level.*
* The X-ray and Particle Sensing (XAPS) project, and the Space Nuclear Sensing Group (ISR-8), are seeking a scientist to plan and execute sensor simulation, constellation level simulation, and/or monitoring tasks for spaced based radiation sensors. As part of USNDS, we design space-based sensors for detecting nuclear detonations in earth's atmosphere and outer space. Our team has diverse skillsets, allowing us to participate in each step of the space hardware lifecycle.

This includes design and production, as well as providing subject matter expertise to sponsors after our hardware is delivered and operational. This results in a highly collaborative team of engineers, scientists, and technicians that work together to solve unique problems at each step of the process.

The team performs outstanding research in the field of space hardware design on problems related to x-ray and particle sensing in space. As part of the team, you should be able to work effectively on both independent tasks and as part of a larger group to develop simulation models to inform sensor design and performance, as well as interpret on-orbit data from our sensors.

Your work will include leading small to medium-size research activities and using state-of-the-art modeling techniques to understand detector response as well as the space environment. In this position you will help develop the next generation of space-based radiation sensors through collaboration with this team as well as external partners.  You will be expected to creatively apply scientific and engineering principles to address sponsor and stakeholder needs while maintaining conduct of operations in a secure workplace.

** Scientist 2 ($106,400 - $176,000):*
* Common tasks for this job could include:

+ Support scientific or technical research and development on projects as an independent contributor under the supervision of senior scientists

+ Develop radiation transport simulations for informing sensor design

+ Perform data analysis of operational data to ensure health of sensors

+ Develop algorithms to interpret data produced by operational sensors

+ Contribute to, or lead, the development of technical outputs such as presentations and reports to be delivered to an external sponsor

+ Collaborate with our engineers, scientists, and technicians to understand system design and requirements as well as provide information to support their work

This position is intended to be an entry level position for recent PhD graduates, preferably with some post-graduate experience.

** Scientist 3 ($128,000 - $215,900):*
* In addition to what was outlined at the lower level, at this level

+ Lead research projects with little to no supervision and report results to stakeholders both internal and external to the Laboratory.

+ Develop and/or contribute ideas for new proposals and business development opportunities. Leads development of technical section of small to medium-sized proposals. Develop new technical capabilities and create opportunities to extend R&D efforts through the expansion of existing capabilities within the Team.

+ Actively participate in professional societies, National Nuclear Security Administration/Department of Energy Complex interactions, special assignments, and/or external collaborations. Participate in external working groups and/or assist in organizing meetings and colloquia.

+ Substantially mentor junior staff, postdoctoral associates, or students on research or manufacturing projects.

The higher level is intended for a scientist who can develop concepts, techniques, and standards for specialized radiation sensing technologies. You should be able to contribute as a technical leader, provide mentorship to other workers, and manage projects of moderate complexity and scope.  You must have a demonstrated record of technical excellence in relating processing and properties in radiation sensor research.

** What You Need*
* ** Minimum

Job Requirements:

*
* + Expertise in at least one of the following topics:

+ Radiation transport using either MCNP or GEANT4

+ Simulations of systems of many detectors

+ Algorithm development for interpreting data from systems of many detectors

+ Demonstrated experience producing technical results from fundamental sciences or supporting operational sensors or development projects.

+ Demonstrated experience leading teams to realize research goals with broad technical impact. Proven ability to reach milestones and produce deliverables.

+ Experience working with experimental data from semiconductors or scintillator-based radiation sensors

+ Demonstrated verbal and written communication skills, especially contributing to technical reports and archival publications.

+ Ability to obtain a DOE "Q" security clearance, which usually requires US citizenship
