Embedded Systems Developer (Networking)

The role spans the full software lifecycle-specification, design, implementation, verification, and validation-on embedded Linux, RTOS, and, when needed, bare-metal microcontrollers. Responsibilities include C / C++ development, driver / BSP integration, control-plane protocol implementations, security hardening, test automation, and comprehensive documentation. Tasks to be performed :

• Develop in C / C++ on embedded Linux / RTOS for ARM / x86-or on bare-metal microcontrollers when needed.
• Integrate and maintain device drivers and BSPs (Ethernet MAC / PHY, switch ASICs, DMA, UART / SPI / I²C).
• Implement and optimize L2 / L3 control-plane functions : VLAN (802.1Q), ARP, STP, VRRP, QoS and contribute to SNMP agents and telemetry.
• Improve system robustness and security : watchdogs, OTA / firmware updates, secure boot, access control, memory protection (scrubbing / ECC), and hardening against potential attacks.
• Automate unit / integration / HIL testing and set up CI / CD pipelines.
• Create and maintain comprehensive documentation : APIs, design descriptions, procedures, manuals; support validation / lab work and production.
• Design test plans and prepare test procedures with a focus on automation.

• University degree and / or PhD in Engineering, Telecommunications, Computer Science or Physics.
• 5+ years of experience in embedded systems with hands-on networking.
• Strong C / C++ skills, concurrency, and debugging (user space and kernel / userland interaction).
• Practical experience with networking equipment and protocols-SNMP, VRRP, STP / RSTP, ARP-on real devices.
• Embedded Linux (Yocto / Buildroot, init / systemd / udev) or RTOS (FreeRTOS / ThreadX).
• Networking fundamentals : Ethernet / 802.3, L2 switching, basic L3 routing, VLANs, 802.1X, QoS.
• Tooling : Git, CMake, Jenkins / GitLab CI, Wireshark, tcpdump.
• Work eligibility : eligible to work in the EU and able to travel to the US-or, at minimum, comfortable with time-zone overlap with US-based teammates.

Preferred skills :

• Familiarity with MIL / ECSS standards for software development.
• Knowledge of DO-178B.
• Experience preparing specifications (e.g., SSS) and supporting SRR; architecture design and functional allocation between software and FPGAs.
• Ability to lead a small team when needed.
