Job Description

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.

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.

  • 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.
