Your Mission

Signal Processing Lead

Core Responsibilities

• Reverse Engineer RF Protocols

  (e.g., telemetry, C2, FSK/QPSK bursts) via IQ analysis using SDR platforms.
• Implement signal models to estimate:
  

• Time of Arrival (ToA)

• Angle of Arrival (AoA)

  via phase-difference or MUSIC/ESPRIT algorithms

• Direction of Arrival (DoA)

  using multi-antenna spatial processing
• Build and deploy robust pipelines for:
  

• RF fingerprinting (RFFI)

  and

  emitter ID

• Modulation classification

  using ML/DSP hybrids

• Frequency hopping and spread-spectrum detection

• Develop

  adaptive filters

  ,

  beamformers

  , and

  matched filters

  for hostile environment operation.
• Work closely with

  FPGA and embedded engineers

  to move prototypes into

  real-time execution

  on constrained compute.
• Simulate scenarios using

  MATLAB, Simulink, or Python

  ; transition to

  C/C++ or VHDL

  where necessary.

You’re Right For This If You Have:

• Proven experience in

  SDR-based signal intelligence

  , waveform decoding, and EW-related DSP.
• Ability to process

  raw IQ data

  , isolate signal-of-interest, and decode or classify protocols (even proprietary or encrypted).
• Strong understanding of:
  

• FFT-based processing

  ,

  TDOA/AOA triangulation

  , and

  multipath mitigation

• Antenna array calibration, diversity gain, and spatial correlation
  
• Experience with tools like:
  GNU Radio, MATLAB, Simulink, BladeRF, USRP, HackRF, AD936x, Xilinx Zynq, TI DSPs
• Knowledge of

  LPI/LPD waveforms

  ,

  burst signal detection

  , and

  anti-jamming techniques

• Deep insight into

  MIL waveforms

  ,

  UAV telemetry

  , or

  custom drone protocols

  is a

  strong advantage

Bonus Points For

• Experience with

  cognitive radio systems

  ,

  spectrum sensing algorithms

  , or
