Embedded Systems Developer (Networking)

Our areas of activity are Aerospace, Defense & Security, Big Science, Biotechnology and Fintech. We are looking for an Embedded Systems Developer to join our networking team. You will start by developing the firmware/software of a Layer-2/Layer-3 switch and then contribute to other embedded systems across space and defense programs. 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.
