Senior Embedded Engineer

Job Description
6+ years of experience in network access devices architecture, with a specialized focus on Wi-Fi technologies.
Strong proficiency in C++, Linux userspace, and Linux kernel-level development.
Deep expertise in Linux-based system architecture, bootloaders with secure boot features (especially U-Boot), drivers, device tree handling, IPC, D-Bus, and software update mechanisms.
Proven experience in handling and debugging serial communication interfaces and peripherals (UART, USB, I2C).
Expert-level knowledge of Wi-Fi standards (802.11a/b/g/n/ac/ax), Wi-Fi Direct, and Bluetooth protocols (Classic & BLE).
Solid background in wireless security protocols (WPA2, WPA3, TLS, ECC, AES), threat/attack mitigation, Linux security hardening, and SELinux.
Practical experience working with RF hardware, antennas, and wireless interference mitigation strategies.
Solid understanding of the TCP/IP networking stack alongside hands-on experience with embedded Linux build systems (Buildroot, Yocto)
Self-organized personality with strong verbal/written communication skills for both technical and non-technical audiences.

Job Responsibilities
Define the end-to-end system architecture for Wi-Fi and Bluetooth communication, including device management over APIs.
Handle, configure, and debug low-level serial communication interfaces (UART, USB, I2C) to ensure stable communication between modules and peripherals.
Define bridging modes for specific Wi-Fi chips and Ethernet interfaces to ensure seamless data routing.
Define and implement wireless protocols for Wi-Fi (802.11) to achieve robust connectivity and low-latency transmission.
Work closely with hardware engineers and embedded developers to guarantee seamless integration between hardware and embedded software.
Address wireless security risks, implementing encryption, authentication, and robust data protection mechanisms across all connectivity layers.
Apply engineering techniques to manage RF interference and ensure signal reliability in complex environments.
Deliver technical guidance to development teams, conduct thorough design reviews, and collaborate directly with regulatory teams.

Department/Project Description
Our client, a leading international hardware and wearable technology manufacturer, is developing an advanced, head-worn situational awareness platform engineered for complex operational and field environments. The system integrates edge computing, multi-sensor video processing, and high-speed wireless connectivity to deliver a seamless, fused real-time data and visual experience for field operators.
The platform architecture centers on a wearable smart power unit anchored by an NXP i.MX 8M Plus System-on-Module (SoM) with integrated Wi-Fi and Bluetooth capabilities, an FPGA for real-time video stream fusion, and dual hot-swappable power modules.
The engineering initiative focuses on optimizing low-level system communication, stabilizing wireless connectivity protocols (Wi-Fi Direct and Bluetooth), resolving USB-OTG switching issues, managing FPGA configuration over I2C, and extracting MIPI CSI-2 stream metadata to ensure a resilient, low-latency system performance.
