5G Telecom Engineer

About the role

LUXUAV is building compact communication platforms for UAV missions and seeks a permanent, hands‑on engineer to lead the design and development of software‑defined 5G NR/LTE nodes on SDR hardware. This technical lead role owns the build from RF front‑end through networking, driving prototypes to field trials.

Key responsibilities

• Design, build, and integrate the software‑defined 5G NR/LTE node on SDR hardware, from the RF front‑end through L1/L2 to an onboard core.
• Own SDR bring‑up and RF integration, including power amplifiers, filtering, antenna chain, TDD timing, and calibration.
• Configure and extend the RAN stack (srsRAN, OpenAirInterface, or commercial equivalent) and integrate the mobile core (5GC/EPC).
• Design and implement networking: IP routing, gateways, backhaul, and mesh‑to‑5G interconnect, ensuring end‑to‑end connectivity and performance.
• Collaborate with the RF/array specialist to integrate phased‑array front‑end at the array‑to‑L1 boundary.
• Stand up bench and hardware‑in‑the‑loop tests, measure and optimise throughput, latency, and coverage, and drive the node from lab to field trials.

Required profile

• Hands‑on industrial experience developing and integrating 4G/5G RAN systems (not research‑only).
• Deep SDR experience with USRP‑class hardware and software‑RAN (srsRAN, OpenAirInterface, or commercial).
• Solid network engineering skills: IP routing, 5GC/EPC, transport and backhaul, with ability to design and debug end‑to‑end.
• Strong C/C++ for real‑time and embedded systems, plus Python for automation and testing.
• Working knowledge of 5G NR/LTE L1/L2 and O‑RAN architecture (Open Fronthaul 7‑2x, O1, FAPI PHY‑MAC API).
• Upper‑intermediate English and a clean criminal record.
• National of a NATO member country or NATO Indo‑Pacific partners (Australia, Japan, South Korea, New Zealand, Ukraine).

Required skills

• SDR hardware (USRP‑class) and software‑RAN (srsRAN, OpenAirInterface)
• RF front‑end integration (PA, filters, antennas, phased‑array)
• IP routing, VPN, SD‑WAN, mesh networking (MANET)
• C/C++ programming, Python scripting
• 5G NR/LTE L1/L2, O‑RAN protocols
• Mobile core integration (5GC/EPC)
