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.

Key Responsibilities:
- 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-productive 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.

Required Skills & Qualifications:
- 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.
- Experience in FMECA, worst-case analysis, and failure-rate modeling of DSP/FPGA subsystems.
- Hands-on experience with FPGA-based DSP implementation (VHDL/Verilog or HLS) and embedded microcontrollers.
- Proficiency in GNU Ra
