Manufacturing Jobs in Rockville, MD (Now Hiring) — 88 open

Quantum Space is redefining mobility and maneuverability in space. Our high-mobility spacecraft platforms support national security, civil, and commercial missions with unmatched flexibility and propulsion capability. We build fast and iterate quickly.

Who We're Looking For

We are seeking an experienced and technically driven Electrical Engineer III – Spacecraft Programs (RF Communications) to lead RF communications subsystem development for next-generation Ranger spacecraft. In this role, you will drive RF communications architecture, subsystem requirements, interface definition, hardware integration, and end-to-end communications system development across complex spacecraft programs.

You will work closely with avionics, power, payload, flight software, guidance, navigation and control (GNC), thermal, mechanical, and systems engineering teams to develop highly reliable communications architectures supporting long-duration, high-mobility missions for national security, civil, and commercial space applications. This position is ideal for an engineer who combines deep RF communications expertise with strong systems thinking and enjoys leading multidisciplinary engineering efforts from concept through flight.

You'll Make an Impact

• Lead RF communications subsystem development across Ranger spacecraft programs from architecture definition through integration, qualification, and flight readiness

• Derive RF communications subsystem requirements from spacecraft- and mission-level requirements while maintaining complete requirements traceability throughout development

• Define and manage RF subsystem electrical and operational interfaces across avionics, payload, GNC, power, and flight software systems

• Author and maintain RF communications Interface Control Documents (ICDs) while supporting spacecraft-level Electrical Interface Control Document (EICD) coordination

• Resolve complex RF integration challenges involving signal integrity, interface compatibility, EMI/EMC, redundancy, and operational performance

• Lead communications architecture trade studies involving radios, amplifiers, antennas, RF routing, frequency planning, and link performance optimization

• Perform make-versus-buy trade studies supporting RF hardware architecture, component selection, and procurement strategies

• Coordinate RF hardware vendors, suppliers, and schedule-critical hardware deliveries throughout subsystem development

• Develop and maintain RF link budgets, communications performance models, and operational analyses throughout the spacecraft lifecycle

• Author RF subsystem integration and test (I&T) plans supporting subsystem verification, vehicle integration, environmental qualification, and mission readiness

• Support spacecraft assembly, integration, environmental testing, launch campaign activities, and on-orbit anomaly resolution

• Collaborate across multidisciplinary engineering teams to ensure communications architectures support mission reliability, manufacturability, operational flexibility, and long-duration mission objectives

• Participate in major engineering reviews including System Requirements Review (SRR), Preliminary Design Review (PDR), Critical Design Review (CDR), Test Readiness Review (TRR), and Flight Readiness Review (FRR)

• Contribute to continuous improvement initiatives that strengthen RF communications architecture, integration processes, and technical standards
