• Your primary responsibility will be supporting efforts to improve timing onboard spacecraft or surface landers for cislunar, lunar and interplanetary missions for both civilian and DoD applications.
• Help to develop analyses, software, and hardware that can be used provide traceability of time in the region and surface of the moon; to establish a Coordinated Lunar Time (LTC) to be referenced back to Coordinated Universal Time (UTC). Exposure to timing analysis based on a relativistic framework is a plus.
• You will provide intellectual leadership to emerging mission concepts and methods of analysis.
• You will hold a vital role on projects while working across teams composed of experts in other engineering disciplines, scientists, and program managers.
• You will be expected to contribute to cutting edge time transfer and navigation methodologies through independent and directly funded research and development.
• You will be expected to leverage and garner relationships across industry and academia to tackle our most critical challenges.
• You will be required to stay abreast of recent advances in academia and industry and apply these concepts to problems of interest.

• Possess a MS in Aerospace Engineering, Computer Science or related field.
• Have significant coursework in the astrodynamics, optimization and estimation, relativistic timing, mathematics, navigation techniques, and/or computer science.
• Have at least 4 years of experience in spacecraft timing, navigation, or another rigorous technical field.
• Possess or are willing to acquire knowledge of GPS, relativistic, weak signal GNSS, and time transfer techniques.
• Are skilled in analytical and numerical computing, such as C++, Fortran, MATLAB, Python, and/or Java.
• Are willing and able to obtain a TS/SCI security clearance. If selected, you will be subject to a government security clearance investigation and must meet the requirements for access to classified information. Eligibility requirements include U.S. citizenship.

• Possess a PhD in Aerospace Engineering, Computer Science or related field.
• Have at least 10 years of experience in spacecraft timekeeping, navigation, or another rigorous technical field.
• Have direct experience with coordinated timekeeping for distributed spacecraft constellations or missions beyond GEO.
• Have experience participating in agile software development projects involving many stake holders.
• Have experience in common astrodynamics software environments such as Monte, STK, ODTK, FreeFlyer, or GMAT.
• Possess an active Top Secret clearance (or above).
• Have possessed and are familiar with network access to DoD related systems.
