Senior Data Scientist

• Own Payload / GW / SAT-RAN data strategy: define key subsystem metrics, data sources, and collection requirements spanning payload, gateway, transport, and RAN/service layers
• Design and maintain SAT-RAN subsystem data models (entities, relationships, identifiers etc) to unify telemetry across domains and support scalable analytics
• Lead data model definition and deployment into production systems: instrumentation requirements, pipeline design, validation, versioning, and data quality monitoring
• Develop performance analytics for overall end-to-end Satellite–RAN performance projected over multiple subsystems, including attribution of impact across payload, GW, transport, core, and RAN layers
• Build failure/anomaly detection and prevention systems using multivariate time-series, correlation/causality-informed approaches, topology/context-aware features, and alert deduplication/triage scoring
• Create qualitative quality scoring models that combine predictive signals with measured KPIs/KQIs, including confidence/uncertainty measures
• Develop fleet service scheduling models, linking orbital state/visibility, predicted SAT-RAN capacity and quality, interference, and spacecraft power/thermal constraints to achievable service performance and demand fulfillment.
• Build decision-support data products: dashboards, health scores, early-warning indicators, incident enrichment, and executive-ready reporting for SAT-RAN performance
• Partner with engineering teams to define success metrics, run backtesting/regression evaluation, and operationalize models into workflows (assurance, release validation, optimization loops)
• Establish best practices for reproducibility and MLOps: model monitoring, drift detection, dataset/version governance, and documentation
דרישות התפקיד
• 5+ years of experience delivering data science / ML solutions in production (monitoring, anomaly detection, forecasting, quality scoring, optimization support)
• Strong proficiency in Python (pandas/NumPy/scikit-learn and time-series tooling) and strong SQL skills
• Demonstrated experience defining and operating data models and analytics pipelines (schemas, identifiers, aggregation logic, data validation, lineage)
• Strong statistical foundations (model evaluation, uncertainty, time-series behavior, bias/variance, backtesting)
• Ability to translate cross-domain system problems into measurable metrics and deployable analytics
• Bachelor’s or Master’s degree in CS/EE/Statistics/Math/Physics or related technical field (or equivalent experience)

Preferred Qualifications
• Multivariate anomaly detection at scale (change-point detection, sequence models where justified, graph/topology-aware features)
• Telecom/systems experience: LTE/5G KPIs/KQIs, OSS counters/alarms, QoE/QoS metrics, RAN performance indicators
• Familiarity with scheduling/capacity modeling concepts (resource allocation, interference-aware capacity, constraint modeling, power/thermal-limited regimes)
• MLOps experience (deployment, monitoring, drift, CI/CD for data + models) and cloud/big-data tooling (Spark or equivalent)
