AST SpaceMobile is building the first global cellular broadband network in space, operating directly with standard unmodified mobile devices. Our satellites serve both commercial and government applications.
What you will do
You will be part of a cross-functional team that owns the full development and operations cycle of satellite electrical and power systems. You will work from requirements specification and architecture development through post-launch data reviews and anomaly investigations.
- Develop and maintain unit- and subsystem-level technical requirements.
- Lead trade studies, architecture development, and interface definition at the unit and subsystem level.
- Support detailed design activities, including creation and review of schematics, layouts, drawings, and bills of materials.
- Perform electrical and power analyses including power integrity (PI), transient analysis, worst-case circuit, derating, voltage drop, and grounding analyses.
- Perform DC, AC, and transient power integrity analysis (IR drop, impedance targets, load steps, resonances).
- Plan and lead unit- and subsystem-level acceptance and qualification testing, including test plan development, EGSE definition, test execution oversight, and test report generation.
- Lead failure investigations and support root-cause analysis during testing and operations.
- Conduct on-orbit data reviews and support anomaly investigation and resolution.
