Signal Processing Engineer (Salem)

Position Overview We are seeking a Wireless Physical Layer Algorithms Engineer to own waveform and DSP design for our satellite communication payloads. You will translate system-level link requirements into complete PHY chains, including modulation, coding, synchronization, and framing, and validate them through simulation and SDR-based prototypes. This is a hands-on role that bridges communication theory, practical DSP implementation, and close collaboration with FPGA and SDR engineers.

Key Responsibilities
- Design end-to-end physical layer waveform chains for satellite links, including modulation, demodulation, coding, interleaving, synchronization, and framing.
- Develop link budgets and performance targets, and translate them into algorithmic and implementation requirements for the payload physical layer.
- Implement and validate DSP algorithms for filtering, timing recovery, carrier recovery, frequency/phase tracking, and signal detection in simulation environments (e.g., Python/C++, MATLAB/NumPy/SciPy, or similar).
- Build and maintain simulation models and test benches for PHY performance evaluation (BER/PER curves, Eb/N0 performance, robustness to channel impairments, etc.).
- Collaborate with FPGA/RTL engineers to partition algorithms between software and hardware, define fixed-point architectures, and support efficient hardware implementation.
- Work with SDR / GNU Radio engineers to bring up reference implementations of the PHY chain on SDR platforms for lab and over-the-air testing.
- Define and refine interface control documents (ICDs), test plans, and design rationale for physical layer algorithms.
- Support troubleshooting and root-cause analysis of link-level issues across simulation, SDR prototypes, and hardware-in-the-loop setups.

Required Qualifications
- Bachelor’s degree in Electrical Engineering, Communications, Electronics, Computer Engineering, or a related field, or equivalent documented qualified experience.
- 3–6 years of experience Apply on Kit Job: kitjob.in/job/4m6obd
