About The Position

Are you interested in hypersonic and reentry system design and prototyping? Do you want to make contributions that accelerate the readiness of our Nation’s defenses to support next generation hypersonic and reentry systems? If so, we're looking for someone like you to join our team at APL. We are seeking an aerothermal engineer to help us perform research, development, design, analysis and prototyping of next generation reentry systems, hypersonic vehicles, and enabling technologies to advance our Nation's premiere strategic weapons systems. As a member of our team, you’ll be making critical contributions to develop these next generation systems, ensuring the enduring effectiveness of our Nation’s strategic deterrent. You will be joining a complementary team of engineers who work together to provide impactful solutions to system level objectives and challenges. We are passionate about innovation and our team is committed to providing engaging challenging work and supporting continued learning and development. As a Reentry System Aerothermal Engineer… Collaborate with cross-discipline teams to develop advanced reentry system designs and prototypes Develop and execute component and/or system-level thermal finite element models to evaluate trajectory-based aerodynamic heating and performance Perform Thermal Protection System (TPS) characterization, selection, and analyses of ablative TPS materials Support aerothermal ground test activities, including test design, test operations, and data analysis. Conduct trade studies on vehicle TPS design concepts As needed, assist in developing software tools for high-speed aerothermal analyses Produce reports and presentations to communicate findings to team members, external organization partners, and government sponsors

Requirements
