Job Description
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 todayâs five billion mobile subscribers and finally bring broadband to the billions who remain unconnected.
Position Overview
This role leads spectrumâcleanliness monitoring and interference analysis across satellite gateway sites and cellular beams, safeguarding spectrum integrity and service quality. You will own continuous RFâenvironment assessmentâincluding noiseâfloor baselining, interference triage, spectrumâoccupancy evaluation, and fieldâofâview (FoV) availabilityâto 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 serviceâquality targets across all markets.
Key Responsibilities
- Spectrum Monitoring & NoiseâFloor Baselines
- Operate routine spectrum scans on satellite gateways, cells, and test beds.
- Establish and maintain noiseâfloor and FoV availability baselines for all markets.
- Detect anomalies, transient interference, and abnormal uplink conditions.
- Interference Analysis & RCA
- Identify, triage, and characterize interference sources (inâband, OOB, PIM, passive vs. active).
- Develop RootâCause Analysis (RCA) inputs and provide remediation recommendations.
- Support live troubleshooting for NOC, labs, and field/acceptance teams.
- Spectrum Dashboards & Reporting
- Publish spectrumâhealth dashboards, KPIs, and occupancy reports.
- Define RF health thresholds and alerting rules for gateways and service beams.
- Maintain playbooks and interferenceâresponse guides for operational teams.
- Regulatory Coordination & Market Support
- Collaborate with regulatory teams on spectrum use, licensing compliance, and interference notifications.
- Support crossâmarket regulatory engagements, especially for shared bands and crossâborder interference.
- Coordinate with partners, operators, and vendors on RF cleanliness and mitigation requirements.
- CrossâTeam 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 beamâavailability analysis.
Qualifications
- Education
- Bachelorâs degree in Electrical Engineering, Telecommunications, RF Engineering, or related field
- 4+ years in spectrum monitoring, RF analysis, spectrum management, or interference engineering in telecom, satellite, defense, or wireless networks.
- Handsâon experience with spectrum analyzers, scanning receivers, driveâtest tools, or automated RF monitoring systems.
- Experience working with regulatory frameworks (FCC, ITU, regional regulators) preferred.
- Preferred
- Satellite or gateway spectrum management experience.
- Familiarity with 3GPP airâinterface fundamentals (uplink channels, interference impact, RF behavior).
- Experience with interference hunting (TSC, IMD/PIM, rogue emitters, external interference).
- Experience with spectrum automation, RF data visualization, or spectrumâintelligence platforms.
- Skills & Competencies
- Strong knowledge of RF engineering and RF diagnostic skills and understanding of interference mechanisms.
- Ability to analyze spectral data at scale and produce actionable insights.
- Handsâon use of RF scanning, monitoring, and analysis tools.
- Clear communicator across engineering, NOC, labs, and regulatory teams.
- Strong problemâsolving and structured RCA abilities.
- Experience documenting and presenting RF findings clearly and concisely.
- CrossâFunctional Interfaces
- Internal: RF Engineering, NOC/Operations, Satellite Systems, Network Performance, Labs & Test, Regulatory, Market Enablement, Program/Project Management.
- External: Spectrum regulators, telecom operators, equipment vendors, monitoringâtool providers, and partner gateway operators.
- Tools / Standards / Methods
- Spectrum analyzers, scanning receivers, automated RFâmonitoring platforms.
- Noiseâfloor trending, occupancy analysis, FFTâbased diagnostics.
- ITU/FCC/global regulatory guidelines.
- Standard interferenceâhunting methods (drive scans, directional analysis, isolation tests).
- Visualization/analytics tools for spectrum reporting and dashboards.
Performance Metrics
- Success measured by:
- Gateway RF health KPIs and spectrumâcleanliness stability.
- Reduction of interference events and faster RCA/mitigation cycles.
- Accuracy and completeness of spectrum dashboards and reports.
- Regulatory compliance adherence and successful partner coordination.
- Crossâteam satisfaction with spectrum insights and responsiveness.
- Physical Requirements
- Role based in US and can be done remotely
- Ability to work in lab environments and occasional field locations.
- Travel to gateway sites, markets, and partners (~20â30%).
- Flexibility for operational escalations outside normal hours.
