Description des tâches LUXUAV is an innovative technology company headquartered in Luxembourg, shaping next-generation airspace security for defence, civil, firefighting and police missions. We build a fully integrated Unmanned Aerial Vehicles (UAV) ecosystem that connects mission systems across ground, air and stratosphere into one coherent governmental and commercial architecture. Job Title: 5G Telecom Engineer - SDR & RAN Design/Development Reports to: CTO Role overview: We are building compact airborne-based communication platforms. We are looking for a permanent, hands-on engineer to lead the design and development of these nodes: the radio stack on SDR, the RF integration and the networking around it. This is a technical lead role, not a management one. You own the build. Programme, customer and stack shortlist are shared during the interview process. 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: SDR platforms, PA, filtering and antenna chain, TDD timing and calibration. • Configure and extend the RAN stack (srsRAN, OpenAirInterface, or a commercial equivalent) and integrate the mobile core (5GC/EPC). • Design and implement the networking: IP routing, gateways, backhaul and mesh-to-5G interconnect, with end-to-end connectivity and performance. • Collaborate with the RF/array specialist on integrating the RF front-end, including phased-array options, into the node 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. Qualifications & Experience Must have • Hands-on industrial experience developing and integrating 4G/5G RAN systems, not research-only. • Very strong SDR skills: USRP-class or similar hardware and software RAN (srsRAN, OpenAirInterface, or commercial), including RF front-end integration. • Solid network engineering: IP routing, 5GC/EPC, transport and backhaul, and the ability to design and debug end-to-end. • Strong C/C++ skills for real-time and embedded systems, with Python for automation and testing. • Working knowledge of 5G NR/LTE L1/L2 and O-RAN architecture (Open Fronthaul 7-2x, O1 and the FAPI PHY-MAC API), sufficient to integrate and optimise solutions. • English at upper-intermediate level or above, and the ability to work with adjacent engineering teams. • Clean criminal record. Nice to have • RF, antenna and phased-array familiarity. • Mesh networking (MANET) and secure transport (VPN, SD-WAN). • Airborne, UAV, aerial-relay or NTN experience • Familiarity with EU spectrum and regulatory requirements. • Proven track record of taking a node from prototype to field trials • National of a NATO member country or one of the following NATO Indo-Pacific partners: Australia, Japan, South Korea, New Zealand or Ukraine.

That number is real. WorkMundi's database shows 144,883 open engineer roles across the world. India has the most with 31,687 jobs, followed by the United States with 30,084. If you just finished reading one job ad and felt paralyzed by choice, you're not alone—but this scale is actually an advantage. It means you can afford to be selective.
Start by geography and language. The majority of engineer ads—117,837 of them—have the job posting text written in English. Use that as one filter, but remember: the ad text language tells you nothing about whether the role actually requires you to speak English day-to-day. Read the job description carefully. Then check which countries have the volume you're targeting. Singapore, Poland, and Australia round out the top five after India and the US.
Next, learn who's hiring. Accenture has posted 2,801 engineer roles. andurilindustries, speechify, and jobgether are also actively recruiting. If you're applying to one of these names, research their hiring patterns and interview style before you apply. That homework pays off.
When you interview, expect the question every engineer hears: 'Tell me about a time you had to debug a problem that wasn't in your job description.' Have a specific story ready—not a general one. Name the tools, the deadline pressure, and what you learned. Hiring managers listen for whether you see problem-solving as part of the role itself, not a favour.
