Company

hirify.global is a defence technology company redefining how autonomous and electronic warfare systems are engineered and deployed for NATO forces.

What you will do

• Design and implement the complete communication software stack for unmanned systems, from physical layer waveform manipulation to network layer routing.
• Develop and integrate anti-jamming techniques, frequency hopping spread spectrum (FHSS), and low-probability-of-detection (LPD) protocols.
• Architect high-reliability data links tailored for small-form-factor UAS operating in contested airspace.
• Write high-performance, real-time C++ code for high-speed data transmission and error correction algorithms (FEC).
• Collaborate with hardware engineers to select and tune front-end components for the physical RF environment.
• Research and implement adaptive filtering and cognitive radio techniques to bypass electronic countermeasures.

Requirements

• Strong proficiency in C++ and deep understanding of embedded systems, RTOS, and Linux networking.
• Professional background in Electronics Engineering with a focus on communication systems and DSP.
• Practical experience with the OSI model as applied to radio-based mesh networks and point-to-point links.
• Deep understanding of digital modulation schemes (OFDM, DSSS, GFSK) and RF propagation physics.
• Ability to debug complex timing issues and signal degradation at the hardware/software boundary.

Nice to have

• Experience building long-range, encrypted data links for robotic platforms.
• Experience with USRP, LimeSDR, and GNU Radio.
• Background in military-grade communication standards (Link 16, MANET) or secure satellite communications.
• Strong mathematical grounding in channel capacity, noise floors, and SINR optimisation.
• Knowledge of MIMO antenna systems, beam-forming, or AI/ML for cognitive radio.

Culture & Benefits

• Opportunity to work on high-performance systems providing decisive advantages to NATO forces.
• Environment grounded in precision, responsibility, and uncompromising engineering discipline.
• Full-stack role bridging the gap between low-level RF hardware and high-level software networking.
• Permanent employment based in Stockholm.
