Job description

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 NR, 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.

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.

Required Experience

• 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 (5GNR/LTE), and 3GPP 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

Preferred Skills and Experience

• 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
