Embedded Systems Developer (Networking)

ARQUIMEA, we are a technology company operating globally and providing innovate solutions and products in highly demanding sectors.

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.

Required skills, experience and candidate profile:

• 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.
