Wi-Fi/DOCSIS Network Engineer

We are seeking a hands-on Senior Embedded Software Engineer to build and evolve next‑generation customer premises equipment (CPE) including DOCSIS 4.0 cable modems and Wi‑Fi 7 routers. You will design and develop firmware across multiple OEM platforms leveraging RDK/RDK‑B, vendor SDKs, and RTOS—owning modules from HAL to application services. The role spans system architecture, driver and middleware development, data models/telemetry (TR‑369), cellular backup integration, and performance/reliability engineering for production-grade devices. Technical Requirements: • Languages: C (expert), C++ (proficient); Python for tooling/automation; Shell scripting. • Platforms: Linux (Yocto/OpenWrt-like build systems), RTOS (FreeRTOS/ThreadX or equivalent). • 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. 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.
