Lead and own the outdoor/field test activities of the team: plan, schedule and execute drive tests, walk tests and field trials of Parallel Wireless 4G/5G ORAN products (radio units, DU/CU and core) in real-world outdoor deployments.
Define the outdoor test strategy, test plans, test cases and acceptance criteria covering coverage, capacity, throughput, latency, mobility (handover/cell reselection), interference and KPI benchmarking against 3GPP and customer requirements.
Design and build outdoor end-to-end test setups: site survey and selection, antenna and RF path, backhaul, power, GPS/timing, UE fleet and measurement tools.
Execute field measurement campaigns with drive-test tools and scanners, and analyze RF and performance KPIs (RSRP, RSRQ, SINR, throughput, BLER, latency, call/session drops, handover success rate).
Analyze and debug UE, RAN and core logs collected in the field and resolve issues in outdoor setups (For Ex: UE/mobile issues, RF/antenna/fiber connectivity, backhaul, power and timing, etc.); isolate RF, baseband, configuration and software issues and drive them to root cause together with R&D.
Analyze, reproduce and validate customer field-found defects and take part in customer trials and field acceptance tests.
Produce clear field test reports and KPI summaries and present findings to R&D, product management and customers.
Mentor and guide junior test engineers; review their test plans, setups and results.
Suggest improvements and changes to the product in order to improve customer experience.
Automation
Define requirements for automating field data collection, KPI post-processing and reporting
Work with the Automation Infra engineers to integrate outdoor test results into the test framework
- Review and consolidate future automation requirements and enhancements for outdoor testing
- Job Requirements:
- 5+ years of hands-on experience in cellular (LTE / 5G NR) outdoor and field testing – drive testing, field trials or RF network optimization.
Proven experience leading field test campaigns and coordinating cross-functional teams (R&D, field technicians, customers).
Strong RF fundamentals: link budget, propagation, antennas, interference, coverage and capacity planning.
Hands-on experience with drive-test tools and scanners (Ex: TEMS, Nemo, XCAL, Rohde & Schwarz ROMES/TSMx, PCTEL) and post-processing tools.
Experience analyzing UE and eNB/gNB logs (Ex: QXDM/QCAT, Wireshark, vendor trace tools) and understanding of architecture and call flows.
Understanding of 3GPP standards covering PHY, MAC, RLC, PDCP, RRC, NAS, S1AP/NGAP and X2AP/XnAP protocols, including mobility procedures.
Experience with RF test equipment (spectrum/network analyzers, power meters, attenuators) and lab tools (Ex: Azimuth, TM500, Amarisoft).
Python and Shell scripting for log parsing and KPI analysis.
Knowledge of handling and troubleshooting User Equipment (Mobiles), SIM installation, etc.
Ability to work outdoors at remote sites, a valid driver's license and willingness to travel locally and abroad as needed.
- Experience in using test management and bug-tracking tools (Ex: JIRA).
- Nice to have:
- Familiarity with ORAN architecture (O-RU, O-DU, O-CU) and multi-vendor interoperability testing.
Experience with network planning and GIS tools (Ex: Atoll, Planet, Google Earth, QGIS).
Experience working with mobile operators on field acceptance and Tier 1 trials.
Experience with LAN/WAN, Routing protocols – L2 and L3, TCP/IP, QoS.
Knowledge of Linux/UNIX-based platforms, Docker and Kubernetes.
- Knowledge of automation frameworks, preferably Pytest
- Education:
- Bachelor degree in Electrical, Electronic Communications/Computer Science Engineering
