Sr Specialist Embedded Firmware Developer

• 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 and troubleshoot robust Layer 2 and Layer 3 network stacks to ensure optimal routing, bridging, and packet forwarding.
• Service Management & Provisioning: Implement and maintain device management and service models, including TR-181 data models and USP (User Services Platform / TR-369).
• Containerization & Lifecycle Management: Configure and manage containerized microservices and virtual execution environments using Docker and prpl LCM (Lifecycle Management).
• Version Control: Manage source code, branching strategies, and firmware release pipelines using Git.

• Experience: 10+ years of hands-on embedded firmware development experience in the telecom, networking, or residential gateway industries.
• Languages: High proficiency in C and modern C++ programming within resource-constrained embedded systems.
• Platform Expertise: Strong working knowledge of Embedded Linux development within OpenWrt or prplOS ecosystems.
• Device Management: Deep, production-level expertise with broadband management standards, explicitly TR-181 data models and USP (TR-369).
• Containerization: Demonstrated experience deploying, isolating, and configuring containerized microservices using Docker and lifecycle tools like prpl LCM.
• Advanced Linux Wireless: Deep knowledge of the Linux Wireless stack, including hostapd, wpa_supplicant, iw, and Linux wireless drivers.
• Networking Protocols: Deep understanding of Layer 2/3 networking and core routing/bridging concepts.
• Profiling & Debugging: Hands-on experience with Linux profiling and debugging tools, specifically perf and Valgrind.
• Version Control: Strong expertise managing source code and branching strategies via Git.

• Next-Gen Wi-Fi: Experience implementing, configuring, or debugging next-generation wireless features like Wi-Fi 6E and Wi-Fi 7.
• Scripting & Automation: Proficiency in Python for creating automated test scripts, hardware validation, or test execution.
• Testing Frameworks: Experience building or maintaining unit testing frameworks (e.g., CUnit, Unity, PyTest) in an embedded context.
• IPC Frameworks: Deep familiarity with OpenWrt ubus and message bus architectures like iMTP.
• Hardware Abstraction: Hands-on experience developing abstraction layers on Broadcom or MaxLinear residential gateway SoCs.
