Aerothermal​/Trajectory Analyst

Company Description

Join us and make YOUR mark on the World!

Lawrence Livermore National Laboratory (LLNL) has turned bold ideas into world-changing impact advancing science and technology to strengthen U.S. security and promote global stability.

Our mission spans four critical national security areas nuclear deterrence, threat preparedness, energy security, and multi-domain defense empowering teams to take on the toughest challenges of today and tomorrow. With a culture built on innovation and operational excellence, LLNL is a place where your expertise can make a real impact.

We have an opening for an Aerothermal and Trajectory Analyst in support of hypersonics and reentry systems under the Flight Performance Integration (FPI) program. Activities include modeling and simulation of hypersonic re-entry bodies, early feasibility studies, flight testing, and software development. You will develop engineering solutions for aerodynamics and aerothermal analysis in support of these programs, from systems requirements trade studies through algorithm design and hardware integration, including test data analyses.

This position is in the Computational Engineering Division (CED), within the Engineering Directorate.

Depending on your assignment, this position may offer a Hybrid schedule, blending in-person and virtual presence. You may have the flexibility to work from home one or more days per week.

This position will be filled at either level based on knowledge and related experience as assessed by the hiring team. Additional job responsibilities (outlined below) will be assigned if hired at the higher level.

• Provide aerospace engineering support for the enduring and future weapons stockpile (both conventional and nuclear) assisting with aerodynamic, aerothermal/ablation, mechanical, and/or trajectory analyses; associated post-processing; and presentation/documentation of results, while adhering to defined practices and procedures.
• Participate, collaborate, and contribute to the development of computational models, and provide support to teams performing analyses and research and development activities in advanced simulation capabilities that utilize state of the art computational techniques and leverage high performance supercomputers.
• Utilize comprehensive engineering knowledge and defined practices and procedures to contribute to the development of models of weapon systems and assist teams with geometry and mesh creation, application of appropriate material models and properties, and evaluation of relevant flight conditions. Participate in the reporting of technical approaches and publishing activities as appropriate.
• Contribute to analyses that support or guide design, testing, modification, and optimization of mechanical components and systems. Participate in formal design reviews and informal peer reviews as required. Support integration and data flow between analysis tools.
• Work closely with a team of analysts, code developers, statisticians, engineers, and subject matter experts to solve problems of limited complexity, evaluating readily identifiable factors and using standard techniques and methodologies.
• Contribute to the fulfillment of technical projects and organizational objectives, collaborate with team members to provide input on deliverables, and regularly communicate the status and projected delivery date to ensure quality results are provided in accordance with established deadlines.
• Support programmatic deliverables with occasional travel, as necessary.
• Perform other duties as assigned.

• Utilize advanced engineering knowledge and broad technical concepts and techniques to contribute to the development of models of weapon systems through geometry and mesh creation, selection or development of appropriate material models and properties, and determination of relevant flight conditions. Collaborate with teams to prepare reports on technical approaches and publish as appropriate.
• Work independently, as well as in conjunction with team members, to participate in the development and implementation of analysis workflow and quality…
