We are building next-generation RF sensing systems for persistent, all-weather detection and tracking. As an RF Digital Signal Processing Engineer, you will own the radar signal processing chain from digitized samples to confirmed tracks, prototyping on SDRs and taking algorithms from model to over-the-air implementation. You will work on detection pipelines, beamforming, target classification, and multi-target tracking, and iterate against real-world data through field tests.

Responsibilities

Own the radar signal processing chain end to end: dechirp, Range-Doppler, detection, angle estimation, track formation
Take algorithms from SDR prototype to real-time implementation with the FPGA/embedded team
Design detection pipelines for small, low-RCS targets - CFAR, clutter suppression, false-alarm management
Develop beamforming, angle estimation, and channel calibration for multi-channel receive arrays
Build target classification (micro-Doppler, drone/bird/clutter) and multi-target tracking
Plan and execute field data collection; iterate against real-world clutter and ground truth

Requirements

Hands-on radar signal processing - your algorithms must have run against real sensor data, not simulation alone
Proven SDR experience (USRP/Ettus, RFSoC, BladeRF, PlutoSDR-class), model to over-the-air demo
Strong FMCW processing: dechirp/stretch, Range-Doppler, waveform parameter design
Detection and clutter: CFAR, Pd/Pfa, MTI/clutter suppression; array processing and beamforming
Target tracking fundamentals: Kalman filtering, data association, track management
Strong MATLAB/Python for algorithms; C/C++ for real-time; delivery to FPGA/SoC/DSP/GPU targets
Eager to learn - treats "I haven't done this before" as a starting point, not a boundary

Nice to have

Pulsed radar processing; micro-Doppler and ML-based classification
Counter-UAS, EW, seeker, or surveillance radar experience
Adaptive processing (STAP, adaptive beamforming); RFSoC/Zynq, CUDA/GPU; VHDL/Verilog literacy
Experience in the Indian defence ecosystem (DRDO, defence PSUs, or defence startups)

Benefits

Core team opportunity at a high-conviction deep-tech startup
Real hardware, real field tests, real impact
Build sovereign defence technology from the ground up in India
