Job VC

Role Overview
We are seeking a high-caliber
Senior RF Systems Engineer
to lead the development of next-generation situational awareness and electronic warfare (EW) platforms. You will be responsible for the full lifecycle of RF subsystems, from initial research (TRL 1) to field-tested operational prototypes (TRL 7+). Your work will directly impact projects such as autonomous drone detection, FHSS signal classification, and distributed SIGINT mesh networks.

Key Responsibilities
RF Design & Integration
Design and optimize RF front-ends for unmanned aerial systems (UAVs) and ground-based detection stations.
Develop hardware and firmware for high-speed FHSS (Frequency Hopping Spread Spectrum) detection and mitigation.
Architect and implement
Mesh Networking
protocols for distributed sensor arrays (e.g., FPV-borne SIGINT mesh).
Signal Intelligence (SIGINT) & Electronic Warfare
Develop algorithms for passive RF geolocation and signal classification.
Engineer solutions for
Drone Detection
, focusing on identifying digital and analogue transmitting signatures even under heavy jamming.
Design and test spoofing detection systems for Galileo and GPS navigation.
Field Validation & Testing
Lead field testing of RF prototypes in relevant operational environments to validate TRL exit criteria.
Analyze battlefield RF signatures to refine "kill zones" and improve EW training simulators.
Collaborate with the software team to integrate RF data into C2 (Command and Control) dashboards.

Technical Requirements
SDR Mastery
Expert proficiency with Software Defined Radio platforms (HackRF, BladeRF, Ettus USRP) and GNU Radio.
Signal Processing
Deep understanding of digital modulation (OFDM, FSK), FFT analysis, and hopping pattern reconstruction.
Hardware
Experience with PCB layout for RF applications (up to 6GHz), antenna design, and impedance matching.
Frequency Bands
Experience working across 300–600 MHz (FHSS), 2.4 GHz, and 5.8 GHz bands.
Tools
Proficiency in MATLAB/Simulink, Python, or C++ for real-time signal analysis.
Proven experience with SAW (Surface Acoustic Wave) filters and LNA (Low-Noise Amplifier) design/integration.

Preferred Qualifications
Knowledge of FPGA development for low-latency signal processing (Verilog/VHDL).
Background in military-grade communication protocols and LPI/LPD (Low Probability of Intercept/Detection) systems.

Logistics & Impact
Location:
Kyiv (Hybrid/Field testing required).
