CFS SOFTWARE DEVELOPER

JOB SUMMARY: The cFS Software Developer (Mid-Level) will support the NASA Goddard Space Flight Center (GSFC) Flight Software Systems Branch on the Early Career Initiative (ECI) Lunar Precision Clock Project. The ECI is a competitive NASA research and development program that advances innovative technologies while developing the next generation of NASA engineers.

This project supports NASA's Artemis Program and future lunar exploration by developing a precision clock instrument capable of accurately measuring and maintaining time on the lunar surface. The technology addresses critical positioning, navigation, communications, and autonomous operations requirements while contributing to the establishment of a future Coordinated Lunar Time (LTC) standard.

The Software Developer will support the development, integration, testing, and sustainment of reusable NASA core Flight System (cFS) applications, software libraries, and interfaces. Working under the guidance of senior engineers, the successful candidate will participate in software requirements analysis, software design, coding, testing, integration, and documentation supporting embedded flight software systems.

The position will collaborate with software, systems, hardware, and algorithm engineers to integrate advanced timing algorithms, develop OpenC3 COSMOS command and telemetry capabilities, support embedded hardware integration on Xilinx PicoZed platforms, and participate in laboratory demonstrations and hardware-in-the-loop testing. Location: Goddard Space Flight Center (GSFC), Greenbelt, MD. This position is a hybrid role requiring on-site attendance every Wednesday, with additional on-site support as required.
