AST SpaceMobile is building the first and only global cellular broadband network in space to operate directly with standard, unmodified mobile devices based on our extensive IP and patent portfolio and designed for both commercial and government applications. Our engineers and space scientists are on a mission to eliminate the connectivity gaps faced by today’s five billion mobile subscribers and finally bring broadband to the billions who remain unconnected. Position Overview This role leads spectrum‑cleanliness monitoring and interference analysis across satellite gateway sites and cellular beams, safeguarding spectrum integrity and service quality. You will own continuous RF‑environment assessment—including noise‑floor baselining, interference triage, spectrum‑occupancy evaluation, and field‑of‑view (FoV) availability—to ensure AST SpaceMobile gateways, terminals, and partner networks operate within expected RF conditions. Through continuous scans, automated baselining, and structured FoV assessments, the role provides acceptance and operations teams with clear, actionable visibility into spectrum risks. By developing and publishing dashboards, thresholds, and response playbooks, this function enables proactive mitigation, supports regulatory alignment, and protects persistence, availability, and service‑quality targets across all markets.

Key Responsibilities

Spectrum Monitoring & Noise‑Floor Baselines

• Operate routine spectrum scans on satellite gateways, cells, and test beds.
• Establish and maintain noise‑floor and FoV availability baselines for all markets.
• Detect anomalies, transient interference, and abnormal uplink conditions. Interference Analysis & RCA
• Identify, triage, and characterize interference sources (in‑band, OOB, PIM, passive vs. active).
• Develop Root‑Cause Analysis (RCA) inputs and provide remediation recommendations.
• Support live troubleshooting for NOC, labs, and field/acceptance teams. Spectrum Dashboards & Reporting
• Publish spectrum‑health dashboards, KPIs, and occupancy reports.
• Define RF health thresholds and alerting rules for gateways and service beams.
• Maintain playbooks and interference‑response guides for operational teams. Regulatory Coordination & Market Support
• Collaborate with regulatory teams on spectrum use, licensing compliance, and interference notifications.
• Support cross‑market regulatory engagements, especially for shared bands and cross‑border interference.
• Coordinate with partners, operators, and vendors on RF cleanliness and mitigation requirements. Cross‑Team Technical Support
• Provide RF environment insights to NOC, performance, lab, field engineering, and acceptance teams.
• Feed spectrum data into acceptance testing, gateway commissioning, and network optimization.
• Participate in FoV modelling, coverage planning inputs, and beam‑availability analysis.
