5G System Integration Engineer

Responsibilities

• System Integration Ownership: Plan and execute integration across core, RAN (O?RAN), PHY/MAC (L1/L2), RF front-end, timing/GNSS, and management/telemetry.
• Test Automation & Tooling: Build CI driven integration test harnesses (E2E attach, bearer setup, handover, throughput/latency, BLER, KPI trending), log analysis pipelines, and reproducible lab scenarios.
• Lab-to-Field Readiness: Drive configuration baselines, soak testing, and pre-flight checklists; support OTA demos and field trials; ensure smooth handoff to customer ops.
• Issue Triage & Root Cause: Lead cross-functional triage (firmware, RF, core, networking), isolate defects, and implement fixes with regression safeguards.
• Performance Optimization: Tune parameters for scheduling, HARQ, beamforming, and RF chains to meet contractual KPIs.
• Compliance & Interop: Validate against relevant specs (e.g., 3GPP call flows for SA, NTN-specific scenarios) and partner equipment interoperability.
• Develop and maintain C++ utilities and Python scripts for automation, log parsing, test harnesses, and debugging workflows.
• Documentation & Repeatability: Maintain integration runbooks, configuration guides, and acceptance test procedures for reuse across customers.
• Participate in Agile ceremonies and demonstrate test results.
