Digital Signal Processing Engineer

We are looking for a Digital Signal Processing (DSP) Engineer to design, implement, and optimize signal processing algorithms and firmware for spacecraft communication systems.

You will work on baseband processing, modulation/demodulation, coding, synchronization, and FPGA-based implementations for S-band and X-band transceivers.

The role spans algorithm development, real-time implementation on SoCs or FPGAs, hardware-software integration, and validation using GNU Radio and SDR platforms.

• Design and implement DSP algorithms for modulation/demodulation, filtering, synchronization, FEC, and channel estimation.
• Develop real-time signal processing pipelines for SDR/FPGAs and embedded processors.
• Implement and test physical layer algorithms (BPSK, QPSK, OQPSK, 8PSK, DVB-S2, etc.) in fixed-point or hardware-efficient forms.
• Work with SDR frameworks such as GNU Radio for simulation, prototyping, and hardware-in-the-loop validation.
• Integrate DSP modules with RF front-end and transceiver hardware (S-band, X-band).
• Collaborate with hardware and firmware teams to co-design FPGA/SoC architectures.
• Perform link simulations, BER analysis, and channel modeling for satellite communication links.
• Optimize signal chains for latency, throughput, and power consumption in embedded environments.

• B.E./B.Tech or M.E./M.Tech in Electronics, Electrical, Communications, or related fields.
• 2–6 years of experience in DSP algorithm development for RF or wireless communication systems.
• Strong understanding of digital communication theory modulation, coding, synchronization, and spectral efficiency.
• Background in error correction coding (LDPC, Turbo, Reed–Solomon) and hardware implementation.
