You could help eliminate them at Skylo.\nSkylo has pioneered a standards-based approach to satellite connectivity. We connect smartphones and IoT devices directly to satellites. No special hardware, no entirely new networks. Just billions of existing devices, suddenly reachable anywhere on Earth. We're not building toward this future. We're already in it.\nOur direct-to-device service is live on millions of activated devices across five continents, covering more than 72 million square kilometers, in partnership with leading satellite operators, mobile network operators, Tier-1 chipset makers, and OEMs worldwide. And we're just getting started.\nAt the heart of it all is Skylo's commercial NTN vRAN: a 3GPP standards-based, cloud-native platform that seamlessly bridges terrestrial and satellite networks. It's the infrastructure that makes true anywhere, anytime connectivity possible.\nWhen you join Skylo, you'll work at the intersection of three markets reshaping how the world stays connected: mass-market consumer devices, automotive, and industrial IoT. Enabling people outdoors and critical workflows in the world's most remote places.\nThis is a rare chance to work on technology that matters, at a company that's already proving it works\nSUMMARY: HOW YOU WILL IMPACT SKYLO\nAs a Staff Network Reliability Engineer, Core Operations, in the Global Product Support & Customer Success organization, you are the 5G Core domain authority within Skylo’s production NTN network. Where the Incident Manager coordinates the bridge, you own the technical outcome. You are the escalation target for every Core-domain Sev 1-2 event - the engineer who diagnoses AMF registration failures, SMF session establishment drops, UPF forwarding anomalies, IMS SIP/Diameter failures, and IMSI provisioning breakdowns at a protocol level, and delivers a resolution or a definitive root cause.\nOn a network where every subscriber is roaming over satellite, Core NF health is the difference between a connected device and a dark one. You own that health - 24×7. You define the KPIs, write and own the runbooks, set the diagnostic standards the entire team operates against, and continuously surface toil and failure patterns as engineering requirements. You are not a first responder; you are the last technical stop before a Core problem becomes an engineering escalation.\nAt Staff NRE level you are also a force multiplier: mentoring Senior NREs in Core domain depth, contributing to the automation backlog with operational requirements, and partnering with Product Engineering to ensure new Core releases meet operational readiness standards before they reach production.\nKEY RESPONSIBILITIES\nCore Network Operations & Health Ownership\nOwn 24×7 5G Core health across Skylo’s production NTN stack: AMF/SMF/UPF/AUSF pod status, NAS/NG-AP signaling success rates, session establishment and tear-down metrics, subscriber registration KPIs, IMS registration state, and Core-layer SLA compliance.\n\nMonitor and triage Core NF alarms using OSS dashboards, Grafana/other inhouse telemetry, and Loki log correlation - distinguish transient anomalies from systemic degradation before escalating or acting.\n\nExecute and own Core-domain runbooks for P2-P4 fault categories: pod restarts, persistent storage recovery, certificate rotation, IMSI state reconciliation, and BSS-IIS cluster incident response - without requiring engineering team involvement for covered fault classes.\n\nMaintain DMP certificate management procedures and own escalation to BOSS (BSS & OSS) for DMP outages, certificate rotation failures, and EMS alarm integration issues.\n\nOwn IMSI lifecycle operations: activation, deactivation, KML file management, subscriber state reconciliation, and exception handling for provisioning failures through the OSS platform.\n\n5G Core Incident Diagnosis & Escalation Authority\nServe as the L3 escalation authority for all Core-domain incidents: take ownership from the Incident Manager, diagnose at the protocol level using NAS traces, NG-AP message flows, Diameter/SIP signaling captures, and NF-specific log analysis, and deliver a resolution or a decision-grade root cause.\n\nLead Core-domain troubleshooting bridges: command the technical investigation, direct vendor and engineering participants, correlate signals across AMF, SMF, UPF, AUSF, PCF, and IMS NFs, and drive the bridge to a documented resolution or a clear engineering handoff.\n\nDiagnose and resolve Core failure modes: UE registration failures, PDU session establishment drops, handover interruptions, IMS registration and call setup failures, SEPP interconnect errors, subscriber provisioning mismatches, and signaling loop conditions.\n\nEngage vendors with technical specificity: reproduce failures with log evidence, own the vendor ticket lifecycle, enforce SLA response commitments, and escalate vendor delays with full impact context.\n\nParticipate in the global 24×7 on-call rotation as the Core domain escalation tier - reachable within defined SLA windows for Sev 1 events; function as the technical decision-maker, not the first responder.\n\nRoot Cause Analysis & Post-Incident Ownership\nOwn Core-domain RCA end-to-end: lead the post-incident investigation, document the complete causal chain from triggering condition through downstream NF impact, and deliver systemic action items with owners, timelines, and measurable success criteria.\n\nDeliver Initial RCA documentation within defined SLA windows post-incident closure; own the final RCA through engineering review and sign-off.\n\nIdentify systemic failure patterns - configuration drift, missing alarm coverage, stale thresholds, vendor software defects - and translate them into engineering requirements with clear impact, scope, and acceptance criteria.\n\nContribute to the weekly and monthly Network Performance Report: Core NF availability, session success rates, MTTR by fault category, top recurring issues, and SLA deviation analysis.\n\nKPI Ownership & Performance Assurance\nDefine, baseline, and continuously refine Core KPIs: NAS registration success rates, PDU session establishment ratios, NG-AP failure rates, IMS registration and session success, UPF throughput and latency, and subscriber provisioning success - calibrated to Skylo’s NTN subscriber population, not vendor defaults.\n\nProactively track Core availability metrics against MNO SLA commitments - flag degradation trends before they breach thresholds and initiate preventive action before a subscriber impact occurs.\n\nEstablish and maintain Core NF performance baselines; detect and investigate deviations that indicate emerging failures, capacity constraints, or configuration regressions.\n\nDrive proactive network issue detection through OSS alarm tuning, alert threshold calibration, and correlation rule improvements - reduce noise, increase signal fidelity, and eliminate alarm storms that mask real events.\n\nRunbook Authorship & Operational Standards\nAuthor, own, and maintain all Core-domain runbooks and SOPs - every procedure must be tested before it is relied upon in production; runbooks are living documents, not static artifacts.\n\nDefine the diagnostic decision tree for each known Core fault class: entry condition, triage steps, isolation method, resolution action, and escalation criteria - written at the level where a Senior NRE can execute independently.\n\nReview and accept runbook contributions from Senior NREs; maintain the Core runbook library as the authoritative operational reference for the team.\n\nIdentify runbook gaps from incident post-mortems and operational observations; prioritize gap closure based on incident frequency and MTTR impact.\n\nCross-Functional Collaboration & Team Development\nPartner with Product Engineering on Core software release readiness: define observability and operational acceptance criteria for new NF versions before they reach production; flag missing alarm coverage, changed default configurations, and new failure modes.\n\nPartner with BOSS (BSS & OSS) on OSS platform stability, IMSI management interface SLAs, and EMS alarm integration - provide operational requirements as input to OSS roadmap planning.\n\nCollaborate with Cloud Infrastructure NRE on Kubernetes-layer issues affecting Core NFs: PVC availability, pod scheduling failures, network policy changes, and GKE upgrade impacts.\n\nSurface toil and automation opportunities to the Service Assurance & Automation team - document the procedure, frequency, and MTTR cost as structured input to the automation backlog; contribute to closed-loop automation requirements for P3/P4 Core events.\n\nMentor Senior NREs in Core domain depth: KPI interpretation, NAS/SIP/Diameter trace reading, log correlation patterns, and escalation judgment.\n\nVendor Management & Engineering Interface\nWork closely with Core NF vendors for incident resolution and RCA - manage vendor ticket lifecycle from opening through closure, ensure reproducible evidence is provided, and escalate responsiveness failures.\n\nEngage Skylo’s Core engineering team with full operational context when issues exceed operational resolution authority - deliver a structured problem statement, timeline, NF log bundle, and a clear question rather than a vague escalation.\n\nSupport MNO partner technical discussions on Core-layer SLA definitions, IMSI provisioning workflows, and subscriber management API behavior - provide operational evidence and data to support partner conversations.\n\nQUALIFICATIONS\nREQUIRED\n8-10+ years of experience in 5G/4G Core operations or Core engineering in a production 24×7 environment - carrier or vendor side, with direct ownership of live Core NF infrastructure.\n\nDeep 3GPP Core expertise: working knowledge of TS 23.501/23.502, NAS protocol, NG-AP/S1AP, IMS architecture (SIP, Diameter, CSCF/TAS), IMSI lifecycle procedures, and subscriber provisioning flows.\n\nProduction 5G Core NF troubleshooting: demonstrated ability to diagnose AMF registration failures, SMF session drops, UPF forwarding anomalies, AUSF authentication failures, IMS SIP/Diameter errors, and SEPP interconnect issues using NF logs and signaling traces.\n\nPacket capture and call flow analysis: proficiency with Wireshark or equivalent for NAS, SIP, Diameter, and HTTP/2 (SBI) protocol-level analysis.\n\nKubernetes-native Core operations: pod health monitoring, rolling restart procedures, PVC and persistent storage management, log aggregation (Loki, ELK, or equivalent), and kubectl proficiency.\n\nProduction observability: Prometheus/Grafana/other inhouse tools for Core NF KPI dashboarding; ability to build queries, set alert thresholds, and interpret metric-level degradation signals.\n\nRunbook authorship: ability to write diagnostic procedures at the level where a less-experienced engineer can execute them independently under incident pressure.\n\nITSM proficiency (Jira, ServiceNow, or equivalent): incident lifecycle management, RCA documentation, and vendor ticket tracking.\n\nStrong written and verbal communication: capable of delivering RCA documents, engineering escalations with structured problem statements, and MNO-facing technical summaries.\n\nPREFERRED\nExperience with NTN or satellite connectivity Core operations: IMSI provisioning for NTN devices, DMP integration, BSS/IIS platform familiarity.\n\nIMS operational experience: SIP registration and session troubleshooting, Diameter routing, CSCF and TAS log analysis.\n\nExperience with OSS/BSS platforms: FCAPS alarm management, EMS integration, SNMP trap handling, and provisioning system diagnostics.\n\nFamiliarity with Core NF vendors: Druid, Nokia (Core), Mavenir, Samsung, or Oracle Core - including vendor CLI tools, log formats, and support escalation processes.\n\nScripting ability in Python or Bash - sufficient to automate log parsing, build diagnostic queries, or create operational data exports.\n\nExperience contributing to closed-loop automation requirements or service assurance platform development.\n\nITIL certificat...","description_format":"text","description_chars":13771,"description_truncated":true,"requirements":{"experience_years_min":8,"management_years_min":null,"team_size_min":null,"manages_managers":false,"education":null,"security_clearance":false,"languages":[]},"benefits":["Equity"],"hiring_locations":[{"name":"India","iso":"IN","kind":"country"}],"hiring_excludes":[],"relocation_offered":false,"industries":["Satellite Communications","IoT Connectivity"],"lifecycle":[{"event":"open","at":"2026-10-08T14:36:09Z"}],"visa":[],"liveness":{"score":90,"band":"hot","label":"Hiring now","p_open":1,"p_active":0.903,"p_room":1,"age_days":1,"expected_fill_days":48,"reasons":["conf:0","velocity","win:early"],"computed_at":"2026-10-10T05:45:15Z"},"pay":null,"html_url":"https://alion.io/job/skylo-technologies-staff-network-reliability-engineer","json_url":"https://alion.io/job/skylo-technologies-staff-network-reliability-engineer.json","meta":{"generated_at":"2026-10-12T03:48:03Z","cache_seconds":300,"methodology":"https://alion.io/methodology","terms":"https://alion.io/terms","contact":"https://alion.io/contact","api":"https://alion.io/developers","about":"Alion is a live layer of people, companies and AI agents: who they are, whether they are real and active right now, what they do and how to work with them, readable by people and by agents and paid per call.","catalog":"https://alion.io/catalog.json","usage":{"tier":"crawler_verified","counted_by":"address","units_charged":1,"used_today":6003,"day_limit":null,"remaining_today":null,"minute_limit":300,"resets_at":"2026-10-13T00:00:00Z"}},"offers":[{"id":"company.slices","title":"One company in depth, by slice","status":"live","price":{"credits":0.02,"usd":0.002,"plus_per_slice":{"credits":0.05,"usd":0.005}},"unit":"per company, plus each slice with data","note":"the employer in depth","call":{"mcp_tool":"get_company","arguments":{"id":5519},"rest":"https://alion.io/mcp/rest/get_company?id=5519"},"human":"https://alion.io/catalog?offer=company.slices&for=job%2Fskylo-technologies-staff-network-reliability-engineer"},{"id":"market.stats","title":"A market slice: pay, demand and time to fill","status":"live","price":{"credits":1,"usd":0.1},"unit":"per slice","note":"pay, demand and time to fill for this role and place","call":{"mcp_tool":"market_stats"},"human":"https://alion.io/catalog?offer=market.stats&for=job%2Fskylo-technologies-staff-network-reliability-engineer"},{"id":"job.search","title":"Open jobs by role, technology, place, pay and visa","status":"live","price":{"credits":0.02,"usd":0.002},"unit":"per posting in a list","note":"similar open postings","call":{"mcp_tool":"search_jobs"},"human":"https://alion.io/catalog?offer=job.search&for=job%2Fskylo-technologies-staff-network-reliability-engineer"},{"id":"company.verify","title":"Is this company real and active right now","status":"pilot","price":null,"unit":"per company","request":{"url":"https://alion.io/catalog/request","method":"POST","body":"{\"offer\": \"company.verify\", \"for\": \"job/skylo-technologies-staff-network-reliability-engineer\", \"note\": \"what you need it for\"}"},"human":"https://alion.io/catalog?offer=company.verify&for=job%2Fskylo-technologies-staff-network-reliability-engineer"}]}
