This position supports the Demonstration Rocket for Agile Cislunar Operations (DRACO) project, a collaboration between DARPA and NASA aimed at developing and demonstrating nuclear thermal rocket engines (NTRE) in space. The engineer will work both independently at times and in an integrated team performing engine systems and system engineering-related activities to enable the design, test, and operation of the DRACO rocket engine. As a key member of the DRACO team, primary duties will include: + Expertise in Nuclear Core Multiphysics (MP) Modeling: Experience with the physics involved in nuclear core dynamics, including heat transfer, fluid mechanics, structures, and nuclear engineering. Proficiency in at least one of these areas, with a strong focus on nuclear engineering, is essential. + Nuclear Reactor Operations: Familiarity with nuclear reactor startup, shutdown, cooldown, testing, and controls is highly desired. Experience with simulating these operational phases is a plus. + Nuclear Reactor Core Materials: Understanding of the materials and nuclear properties of nuclear reactor cores, particularly those used in nuclear thermal propulsion systems. + Simulation Software Proficiency: Experience with simulation tools such as MCNP and OpenMC is highly desired. Familiarity with MOOSE is also valuable. + Nuclear Fuel Performance: Solid understanding of nuclear fuel performance, including the ability to model the nuclear, chemical, and mechanical effects of fuel under varying operational conditions. + Cross-Disciplinary Collaboration: Proven ability to interface successfully across multiple organizations and disciplines, ideally in a leadership or collaborative capacity. + Software Integration: Strong ability to efficiently integrate disparate software systems and work comfortably in a networked environment, particularly on Linux systems and high-performance computing (HPC) platforms. + Modeling & Simulation Software Development: Experience with M&S software development, including parallel processing and efficient solution algorithms, is highly desirable. + Coordinate, develop, and present technical materials related to engine system performance and testing in support of design milestone reviews and anomaly investigations. + Document and maintain test and data analysis processes in written work instructions. + Participate in relevant trade teams. Identify and pursue resolution of issues. + Identify and document customer objectives and product requirements. + Other duties as assigned. **Qualifications** Typically, educational requirements are the equivalent of a minute of a Masters with at least 3 years of experience, or BS with at least 5 years experience. Qualifications include: + A background in computer science or related fields is highly desired. Additionally, the ability to translate engineering physics concepts into computational models and engage with the engineering community to implement these models is crucial. + Computational Science Engagement: Proven ability to articulate the needs, concerns, and opportunities from a computational science perspective while collaborating with the engineering and physics communities.
