Senior Embedded Software Engineer (Wireless Networking)

About the Role

Key Responsibilities

• Full Communications Stack Network Debugging & Optimization: Diagnose and resolve complex network connectivity, throughput, latency, and reliability issues across the entire networking stack, from the wireless radio (PHY/MAC layers) through TCP/IP and up to the application layer on embedded IoT devices.
• Protocol Implementation & Tuning: Implement, port, and optimize low power wireless (802.11, HaLow, Thread) and TCP/IP protocols to meet specific performance, power, and memory constraints of embedded systems.
• Performance Analysis: Conduct in-depth performance analysis of wireless and networking stacks, identifying bottlenecks and proposing innovative solutions for optimization (e.g., retransmission strategies, buffer management, concurrency, power management, scheduling).
• Root Cause Analysis: Perform detailed root cause analysis of intermittent and hard-to-reproduce networking issues using advanced debugging techniques and tools.
• Cross-Functional Collaboration: Work closely with hardware engineers to characterize RF performance, integrate drivers, and troubleshoot hardware-firmware interactions. Collaborate with application software developers to ensure seamless integration and optimal use of network services.
• Testing & Validation: Define and help develop comprehensive test plans for wireless, including unit, integration, and system-level tests with QA and Automation teams.
• Stay Current: Keep abreast of the latest advancements in wireless technologies, networking protocols, and embedded systems.

Requirements

• Bachelor's or Master's degree in Electrical Engineering, Computer Engineering, Computer Science, or a related field.
• 5+ years of experience in embedded firmware development with a strong focus on wireless networking.
• Expert-level proficiency in C/C++ for embedded systems.
• Deep understanding of the entire TCP/IP networking stack (Layers 2-7), including Ethernet, IP, TCP, UDP, DNS, DHCP, Thread, etc.
• Extensive experience with WiFi (802.11) protocols, including MAC layer operations, roaming, power saving modes, and coexistence.
• Hands-on experience with embedded operating systems including FreeRTOS and Linux.
• Experience with various microcontrollers (e.g., ARM Cortex-M/R) and their peripherals.
• Proven ability to optimize embedded networking stacks for throughput, latency, power consumption, and memory footprint.
• Strong understanding of network security concepts, protocols, certificates/keys, firewalls, packet inspection and filtering.
• Familiarity with tools such as Wireshark, Communications Analyzer, Traffic/Load generators, Network throttling, Wireless impairment test setups.
