5G System Integration Engineer

Job Summary

We are seeking a highly skilled 5G Systems Integration Engineer with a strong background in gNB system architecture, integration, and validation. The ideal candidate has hands‑on experience with 5G , O‑RAN components, and end‑to‑end system bring‑up, as well as practical programming skills (C++ preferred) to support automation, debugging, and custom tooling development.

• 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., 3
  
  GPP 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.

• Bachelor’s degree in Electrical Engineering, Computer Engineering, Computer Science, or related field
• Strong understanding of cellular architecture (5G or 4G LTE): RAN, air interface (5
  
  GNR/LTE), and 3
  
  GPP standards
• Hands‑on wireless systems test experience: performance, interoperability, protocol testing
• Proficiency with test equipment: signal generators, spectrum analyzers, UE simulators, protocol analyzers
• Proficiency in C++ for tooling, integration support, and system‑level development
• Strong cross‑functional triage and documentation skills

• Viav TM500 UE simulator experience
• Customer deployments, field testing, or carrier certification processes
• Ability to write clean, maintainable, production‑grade C++ (C++14/17/20 experience preferred)
• Experience with NTN scenarios, OTA demos, and lab‑to‑field transitions
