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 SoC platforms, dynamic RF control loops
(AGC, tilt, gain), and modern cable plant telemetry via gNMI,
Protobuf, and
MQTT.

How
will you help us connect the world:
●
Broadcom Cable SoC Integration: Develop low-level firmware using
Broadcom SDKs tailored for Broadband/Cable Access SoCs 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 I2C, 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 modern out-of-band
management and monitoring agents using gNMI (gRPC 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 & Validation:
