About the role
Posted: 2026-10-22
Parallel Wireless is transforming its Feature-Validation & Stability organization into a single Prod-Dev team — in the AI era there is no longer a separate "development" vs "validation" team. We are building a group of strong System Engineers who own a problem end to end: understand the complete product behavior, find the actual root cause, and contribute directly to the fix — accelerated by Claude / AI-assisted engineering. This is a pro-development, system-level problem-solving role. You will take a field or test issue and drive it the whole way: Issue → Reproduction → Cross-layer analysis → RCA → Code investigation → Fix → Validation You will not stop at "which component failed." You will name the root cause, prove it, and fix it.
What you would do
- Deep, cross-layer 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 (Friendly-Operator) setups. - Investigate code and deliver bug fixes — own the fix through to validation, not just the analysis note. - Field-issue investigation with direct customer / field involvement; feed learnings back into design, regression and stability. - Feature development driven by design/framework gaps and customer-driven requirements. - Use AI tools (Claude / AI-assisted engineering) to accelerate code understanding, log analysis, debugging, correlation and RCA — especially on multi-module problems. - Identify scenarios, improve monitoring/validation coverage, and raise the quality bar before issues reach the field.
What they are looking for
- Strong software engineering in C / C++ (and Python for tooling/automation) with the ability to read and fix production RAN stack code.
- 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.
- 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.
