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-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. 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 Radio, MATLAB/Simulink, or Python for algorithm design and verification. • Familiarity with SDR hardware platforms. • Understanding of RF front-end characteristics (gain, noise figure, bandwidth, I/Q balance, etc.). Nice to Have (Preferred): • Experience with DVB-S2/X, CCSDS, or similar space communication protocols. • Familiarity with real-time OS or Linux driver development for SDR systems. • Exposure to beamforming, MIMO, or adaptive modulation schemes. • Prior experience in satellite communication systems, CubeSat payloads, or ground station SDRs. • Experience with co-simulation environments (MATLAB–FPGA or GNU Radio–SoC integration). • Willingness to work extended hours and/or weekends as needed.
