Lead Space Power Systems Engineer

AST SpaceMobile; Lanham (MD); On-site; USD 120,000 - 170,000; Full time

Job summary

AST SpaceMobile is seeking an Electrical and Power System Engineer to help develop next‑generation satellite power systems. You will join a cross‑functional team responsible for requirements, architecture, schematics, and integration of power subsystems for on‑orbit assets.

The role emphasizes design leadership, performance analysis, PDN validation, and on‑orbit data reviews, with a focus on space mission requirements and rigorous testing. Strong collaboration and communication are essential.

Qualifications

• Bachelor’s degree in electrical engineering with strong academic performance.
• Familiarity with electrical power system components such as batteries, solar panels, harness, and power control and distribution units.
• Legally authorized to work in the US without employer sponsorship.
• Excellent communication abilities, both written and verbal.
• Strong analytical and problem-solving skills.
• Familiarity with satellite power systems and space mission requirements.
• Familiarity with PDN simulation tools (Keysight PIPro, Cadence Sigrity, Ansys SIwave, SPICE).
• 2+ years of experience leading a team or technical project.

Responsibilities

• Develop and maintain unit- and subsystem-level technical requirements.
• Lead trade studies, architecture development, and interface definition at unit and subsystem levels.
• Support detailed design activities, including schematics, layouts, drawings, and BOMs.
• Perform electrical and power analyses including power integrity, transient analysis, derating, voltage drop, and grounding analyses.
• Perform DC, AC, and transient power integrity analysis (IR drop, impedance targets, load steps, resonances).
• Optimize decoupling strategies across frequency domains.
• Define and execute PDN validation plans (impedance measurement, load-step testing, noise analysis).
• Plan and lead unit- and subsystem-level acceptance and qualification testing (test plans, EGSE, test reports).
• Lead failure investigations and support root-cause analysis during testing and operations.
• Conduct on-orbit data reviews and support anomaly resolution.
