Senior Embedded Engineer

New Hampshire (Onsite)

Must Have: C++ Linux, Embedded, Networking, Wifi

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.
