Flight Software Systems Engineer

Position: FLIGHT SOFTWARE SYSTEMS ENGINEER
JOB SUMMARY:

The NASA Software Engineering Services III (SES-III) contract provides engineering expertise supporting the development, integration, testing, deployment, and sustainment of NASA flight software systems. MVS is seeking a Flight Software Systems Engineer (Chief) to provide end-to-end flight software systems engineering leadership supporting the Advanced Limb Infrared Chemistry Experiment (ALICE) instrument for NASA's Stratosphere-Troposphere Research via Innovative Viewing Experiments (STRIVE) mission at NASA Goddard Space Flight Center (GSFC) in Greenbelt, Maryland.

STRIVE is NASA's next-generation Earth Science mission designed to improve understanding of atmospheric processes, including stratosphere-troposphere interactions and their impact on ozone, weather, climate, and air quality. The ALICE instrument provides advanced infrared limb observations of atmospheric temperature, ozone, trace gases, aerosols, and clouds with unprecedented spatial resolution and sensitivity.

The Flight Software Systems Engineer serves as the technical authority responsible for the complete software systems engineering lifecycle supporting the ALICE instrument. This position provides leadership from mission formulation through mission operations, including conceptual design, software requirements engineering, architecture development, interface definition, implementation oversight, integration, verification and validation, launch preparation, and on-orbit sustainment. The successful candidate will collaborate across multidisciplinary engineering teams while remaining technically engaged in software architecture, embedded flight software development, and system integration activities.

Work Schedule:
