UAV Comms & Protocols Engineer (m/f/d)

We’re hiring a Comms & Protocols Engineer to architect and deploy advanced communications stacks for distributed counter-UAS systems. Your work will span SDR, mesh networking, NATO-compliant interfaces, and redundant fallback systems - all optimized for real-world tactical performance.

This is a hands-on systems role, blending RF, embedded protocols, and autonomy integration. You’ll enable reliable drone-to-drone, interceptor-to-effector, and ground comms even in degraded, contested RF environments.

Tasks

Develop secure and redundant communications protocols for CUAS and autonomous UAV networks

• Program SDRs using GNU Radio, USRP/Ettus platforms, and custom FPGA pipelines


• Integrate NATO SAPIENT protocol stacks and other defense-standard interfaces


• Build and optimize mesh comms using LoRa, CAN bus, and low-SWaP datalink layers


• Design, test, and validate antenna layouts and RF propagation under dynamic flight conditions


• Work with autonomy, targeting, and perception teams to ensure reliable low-latency messaging


• Validate entire stack in HIL setups and field trials with autonomous air vehicles

Requirements

• 4–8+ years in embedded comms, SDR, or RF engineering


• Experience programming SDR platforms (GNU Radio, USRP, LimeSDR, etc.)


• Familiarity with secure mesh networking (LoRa, CAN, custom protocols)


• Knowledge of NATO SAPIENT or other military-grade comms protocols


• Solid foundation in antenna theory, RF propagation, and EMI-aware design


• Proficiency in C/C++ and/or Python for embedded protocol development


• Comfortable working across hardware and software boundaries

Bonus Points For:

• Experience with fault-tolerant comms or degraded RF environments


• Knowledge of custom protocol design or real-time distributed systems


• Background in CUAS, drone swarms, or autonomous battlefield networks


• Tools: GNURadio Companion, SDRangel, Qucs, MATLAB RF toolbox

Benefits

• Be part of a mission to reinvent autonomy for real-world impact


• Build secure, resilient comms for next-gen autonomous systems


• Work in a custom-built RF & UAV testing lab at Berlin TXL


• Competitive salary + meaningful equity


• Full-time, on-site role with a focus on rapid iteration and deployment

Who You Are

You’re obsessed with signal integrity, latency, and making sure the system always talks - even when the spectrum is contested and the drone is miles away. You don’t just connect radios — you engineer communication as a battlefield advantage.
