Senior Engineer, Production Dev (QA Automation (AI & Root Cause Analysis)

- Integration/System/E2E Featue Validation of PW products (LTE/NR/GSM)

- Use AI tools (Claude / AI-assisted engineering) to accelerate code understanding, log analysis, debugging, correlation and RCA — especially on multi-module problems.

- Identification of the scenarios, enhance the coverage to make the product robust & stabile

- Analysis of the issue/RCA on field and lab issues that span multiple modules, correlating evidence across the full stack:

- → UE logs · PHY logs · DU / MAC / SCH logs · CU / L3 logs · Core logs · Platform logs · RRH logs · System logs · field issues across EMS / system monitoring.

- Reproduce field/customer issues in the lab on production-like setups.

- Field-issue investigation with direct customer / field involvement; feed learnings back into design, regression and stability.

- Automation of the E2E features

- Solid wireless/telecom system understanding across 2G / 4G LTE / 5G NSA / SA — RRC, S1AP/NGAP, X2/Xn, PDCP/RLC/MAC scheduling, PHY/FAPI, GTP-U, and the core/platform interfaces.

- Handson experience in Python/Pytest for tools/automation scripting

- Proven debugging & RCA skills: coredumps/gdb, log/PCAP analysis, memory/crash triage, KPI/counter reasoning.

- A system mindset — comfortable reasoning across UE ↔ RAN ↔ Core ↔ Platform ↔ EMS rather than a single layer.

- Willingness and aptitude to work with AI tools as a daily engineering accelerator

- O-RAN / disaggregated CU-DU, fronthaul (split 7.2), PTP/timing, IPsec/transport exposure.

- Experience with EMS / OSS, Kibana/KPI monitoring, PM counters.

- Prior field / customer-facing deployment or NPI experience.
