About the role

Key responsibilities & impact

Own 24×7 NTN RAN health across Skylo's production network: gNodeB/eNodeB status, node availability, attach and access success rates, RRC setup and abnormal release behavior, RF integrity (SINR, RSSI, noise floor stability), and RAN-layer SLA compliance.
Monitor and triage RAN alarms using OSS dashboards, Grafana/inhouse telemetry, and NTN-specific alarm patterns — distinguish transient RF fluctuations from systemic degradation before escalating or acting.
Execute and own RAN-domain runbooks for all fault categories: cell outage recovery, timing resynchronization, parameter rollback, restart procedures, and interference mitigation actions — without requiring engineering team involvement for covered fault classes.
Own timing and synchronization health: GNSS lock status, Octoclock/reference clock drift, PTP/SyncE alignment, and NTN-specific timing compensation — detect and resolve timing anomalies before they cascade into access failures.
Monitor beam-level and cell-level performance across the NTN coverage area; identify underperforming beams and initiate optimization or escalation based on defined criteria.
Serve as the L3 escalation authority for all RAN-domain incidents: take ownership from the Incident Manager, diagnose at the RF and protocol level using eNodeB/gNodeB logs, RF telemetry, PRACH/MSG1–MSG5 analysis, RRC traces, and KPI correlation, and deliver a resolution or a decision-grade root cause.
Lead RAN-domain troubleshooting bridges: command the technical investigation, direct vendor and engineering participants, correlate signals across RU, DU, CU-CP, CU-UP, and timing subsystems, and drive the bridge to a documented resolution or a clear engineering handoff.
Diagnose and resolve RAN failure modes: SINR anomalies, beam coverage gaps, preamble failures (MSG1–MSG5), RRC setup failures, abnormal RRC releases, CW/narrowband/adjacent-carrier interference, cell unavailability, eCPRI link failures, and DU/CU software faults.
Engage RAN vendors with technical specificity: reproduce failures with log evidence and RF traces, own the vendor ticket lifecycle, enforce SLA response commitments, and escalate vendor delays with full impact context.
Participate in the global 24×7 on-call rotation as the RAN domain escalation tier — reachable within defined SLA windows for Sev 1 events; function as the technical decision-maker, not the first responder.
Own RAN-domain RCA end-to-end: lead the post-incident investigation, document the complete causal chain from triggering RF condition or hardware event through downstream subscriber impact, and deliver systemic action items with owners, timelines, and measurable success criteria.
Deliver Initial RCA documentation within defined SLA windows post-incident closure; own the final RCA through engineering review and sign-off.
Identify systemic RAN failure patterns — recurring interference sources, timing drift trends, vendor software regressions, hardware batch faults — and translate them into engineering requirements with clear impact, scope, and acceptance criteria.
Contribute to the weekly and monthly Network Performance Report: RAN availability by beam/cell, attach success rates, MTTR by fault category, top recurring issues, and SLA deviation analysis.

Requirements

What you’ll need

8–10+ years of experience in RAN engineering and operations in a production 24×7 environment — carrier or vendor side, with direct ownership of live LTE/5G RAN infrastructure. NTN or satellite RAN experience strongly preferred.
Deep 3GPP RAN expertise: TS 38.300, NR/LTE-NTN procedures, NB-IoT/LTE-M/5G-NR air interfaces, UE random-access procedures (PRACH/MSG1–MSG5), RRC state machine, and beam management.
Extensive understanding of vRAN/ORAN architecture: 7-2x split functions, RU/DU/CU-CP/CU-UP component roles, eCPRI/CPRI interfaces, and virtualized RAN software systems.
Production RAN troubleshooting: demonstrated ability to diagnose SINR anomalies, beam coverage gaps, preamble failures, timing drift, interference conditions (CW, narrowband, adjacent carrier), and RU/DU/CU hardware and software faults using RF telemetry and gNB logs.
RF and timing domain knowledge: GNSS, PTP, SyncE, Octoclock/reference clock behavior, and NTN-specific timing compensation mechanisms.
Production observability: Prometheus/Grafana/in house tools for RAN KPI dashboarding; OSS alarm integration (SNMP, Pub/Sub, or equivalent).
Packet capture and trace analysis: proficiency with Wireshark or equivalent for L2/L3 call flows, PCAP analysis, and gNB trace decoding.
Kubernetes operational literacy: pod health monitoring for DU/CU workloads, kubectl proficiency, log aggregation and correlation.
Runbook authorship: ability to write RAN diagnostic procedures at the level where a less-experienced engineer can execute them independently.
Strong written and verbal communication: capable of delivering RCA documents, engineering escalations, and MNO-facing technical summaries.
