Wi-Fi/DOCSIS Network Engineer

Job DescriptionWe 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.
Roles 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.
Technical Requirement

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.
Additional ResponsibilityNice-to-Have / Preferred:

Wi-Fi 7 expertise: MLO, 320MHz 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.
