Sr Specialist Embedded Firmware Engineer – Residential Gateways (prplOS & Wireless)Role Overview
We are looking for an Embedded Firmware Developer with 8+ years of experience to drive the design direction, optimization, and scaling of our next-generation Residential Gateway products. Our software architecture leverages prplOS, making our platform inherently SoC-independent across diverse silicon, including Broadcom and MaxLinear SoCs.
In this role, you will serve as the technical authority for our embedded firmware and wireless stack. You will own the Linux wireless architecture, scaling our platform to support cutting-edge Wi-Fi 6E and Wi-Fi 7 capabilities, while ensuring carrier-grade stability through deep system-level profiling and optimization using tools like perf and Valgrind. Additionally, you will champion automation by using Python scripting to build robust testing and unit testing framework methodologies that ensure code quality across the entire lifecyle.
Key Responsibilities
Test Automation & Scripting:
Architect and implement automated testing and unit testing frameworks using Python to validate system components, APIs, and overall firmware reliability.
Performance Profiling & Optimization: Use perf, Valgrind (Memcheck, Massif, Helgrind), and kernel utilities to profile OS memory and CPU management, eliminate memory leaks, resolve race conditions, and minimize CPU bottlenecks.
Wireless Stack & Driver Integration: Design, configure, and optimize Wi-Fi 6E and Wi-Fi 7 features using hostapd, wpa_supplicant, and iw sub-systems.
Firmware Development: Architect, develop, and maintain high-performance firmware in C and C++ across various gateway hardware platforms.
SoC Abstraction: Leverage prpl APIs to maintain hardware-agnostic implementations across multiple carrier-grade SoCs.
Inter-process Communication (IPC): Develop and maintain scalable services utilizing ubus and/or iMTP to ensure reliable internal bus communication.
Network Stack Management: Design
