Wi-Fi/DOCSIS Network Engineer

Responsibilities

• Design, develop, and port RDK/RDK‑B or vendor SDK modules on routers/modems across different OEMs.
• 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.

Additional Responsibilities

Nice-to-Have / Preferred:

• Wi‑Fi 7 expertise: MLO, 320 MHz channels, multi‑RU scheduling, AFC (where applicable).
• Experience with cellular modems (LTE/5G), failover and bonding, multipath.
• RDK telemetry adapters, USP controllers/agents, vendor data model mapping.
• Rust for systems modules (safety-critical or performance-sensitive components).
• Exposure to OpenWrt, prplOS/prplMesh, EasyMesh, and board bring‑up.
• Manufacturing line support: factory calibration, RF tests, firmware provisioning.
• Security: secure boot, trusted execution, key management, certificate provisioning.
• Compliance/certification: Docsis, Wi‑Fi Alliance, FCC/CE, operator acceptance test processes.

• Frameworks/Stacks: RDK/RDK‑B, Docsis (preferably 3.1/4.0), SNMP, TR‑369 (USP), TR‑069 (nice to have).
• Networking: Wi‑Fi (802.11ac/ax/be), TCP/IP, VLAN, QoS, NAT, firewall, routing, policy-based failover.
• Drivers/Middleware: GPIO/I2C/SPI/USB, LED/FAN control, audio subsystems, diagnostics, logging.
• Toolchains & Build: GCC/Clang, CMake/Make, cross-compilers, JTAG/UART, bootloader (U‑Boot), BSP/HAL.
• Version Control & CI: Git, GitLab/GitHub CI, artifact management, automated unit/integration tests.
• Quality & Reliability: Profiling, memory/performance optimization, watchdogs, crash analysis, core dumps.
• System Architecture: Module boundaries, IPC, threading/concurrency, resource management.
