Implement C/C++ control services for LED, USB, FAN, and system state displays for cable modems/routers.




Develop RTOS modules/drivers, SNMP interfaces, SSH/Telnet support, and voice/audio features.
Build data control modules for Wi‑Fi 7 routers including cellular backup orchestration.
Design TR‑369 (USP) based data collection/telemetry modules and define robust data models.
Own system architecture, performance tuning (CPU/memory/latency), and reliability (watchdogs, crash dumps).
Collaborate with hardware, QA, and cloud/DevOps teams for manufacturing tests, CI/CD, and field telemetry.
Write high-quality design docs, test plans, and release notes; participate in code reviews and certification prep.
Troubleshoot field escalations and drive root cause analysis across firmware, drivers, and network stack layers.
