Job Summary

We are seeking a skilled and motivated RF Signal Processing Engineer with 3–4 years of hands-on experience in developing, simulating, and implementing algorithms for RF and communication systems. The ideal candidate will have a solid understanding of RF principles, digital signal processing (DSP), and practical experience with tools like MATLAB, Python, and SDR hardware platforms.

Key Responsibilities:

• Design and implement signal processing algorithms for RF front-ends, receivers, and transmitters.
• Simulate and analyze RF signals and communication protocols (e.g., QPSK, OFDM, CDMA).
• Work on signal acquisition, filtering, detection, demodulation, and decoding techniques.
• Support system integration with hardware platforms including Software Defined Radios (SDRs).
• Perform RF measurements, lab testing, and validation of developed signal processing blocks.
• Develop and implement advanced radar signal processing algorithms including pulse compression, Doppler processing, CFAR detection, and tracking filters.
• Design and simulate radar waveforms for various applications such as SAR (Synthetic Aperture Radar), MTI (Moving Target Indicator), and FMCW radar systems.
• Analyze radar system performance and signal integrity under various noise, jamming, and multipath conditions.
• Optimize real-time signal processing pipelines using embedded platforms (DSPs, FPGAs, or GPUs).
• Collaborate with cross-functional teams including RF design, embedded systems, and firmware.
• Prepare technical documentation, reports, and presentations.

Required Skills & Qualifications:

• B.E./B.Tech or M.E./M.Tech in Electronics, Communication, or a related field.
• 3–4 years of experience in RF systems and digital signal processing.
• Strong foundation in RF propagation, antenna theory, and communication systems.
• Proficient in MATLAB/Simulink, Python (NumPy/SciPy), and C/C++ for DSP implementations.
• Experience with SDR platforms such as USRP, HackRF, or similar.
• Knowledge of modulation/demodulation, FFT, filtering, error correction codes, etc.
• Familiarity with RF test equipment: spectrum analyzers, signal generators, VNA.

Preferred Qualifications:

• Experience with GNURadio, LabVIEW, or FPGA-based signal processing.
• Background in radar signal processing or satellite communication systems.
• Familiarity with DO-254/DO-160 or similar aerospace standards (for aerospace/defense roles).

Soft Skills:

• Strong analytical and problem-solving skills.
• Good communication and teamwork abilities.
• Willingness to learn and adapt to emerging technologies.

Perks & Benefits:

We also welcome women with career gaps and applicants from non-aerospace or defence sectors who can bring valuable skills and experiences to our team.
