In our ‘always on’ world, we believe it’s essential to have a genuine connection with the work you do.
We are seeking a Senior Embedded Firmware Engineer to join our cable access engineering team, co-developing directly with our US-based systems architects, software and hardware teams.
In this specialized role, you will design and maintain firmware for next-generation Full Duplex (FDX) Cable Amplifiers and smart RF nodes. Rather than Ethernet switching, your focus will be at the intersection of embedded Linux, Broadcom broadband So C platforms, agile RF control loops (AGC, tilt, gain), and modern cable plant telemetry via g NMI, Protobuf, and MQTT.
How will you help us connect the world:
● Broadcom Cable So C Integration: Develop low-level firmware using Broadcom SDKs tailored for Broadband/Cable Access So Cs to initialize, configure, and monitor digital/analog RF processing hardware.
● RF Control & Signal Processing: Implement embedded control loops for Automatic Gain Control (AGC), Automatic Level Control (ALC), tilt adjustment, energetic power management,



and echo cancellation in Full Duplex RF amplification stages.● Hardware Interfacing & Bus Management: Control on-board peripherals, RF attenuators, equalizers, power amplifiers, and environmental sensors over I2 C, SPI, and GPIO interfaces.
● Linux Kernel & Low-Level Driver Development: Write and maintain custom Linux kernel drivers, character devices, and user-space daemons interacting directly with hardware registers and memory-mapped I/O.
● Streaming Telemetry & Remote Management: Architect contemporary out-of-band management and monitoring agents using g NMI (g RPC Network Management Interface), Protobuf (Protocol Buffers), JSON, and MQTT for real-time health and RF performance metrics.
● US Co-Development & Technical Collaboration: Actively participate in joint design reviews, code reviews, and architectural planning with US-based firmware, RF hardware, and systems engineering teams.
● Hardware Bring-Up & Validat
