About the Role

We are looking for a highly motivated GNSS Signal Processing Engineer to join our team at VyomIC, where we are building the next-generation Global LEO- PNT(Positioning, Navigation, and Timing) satellite constellation from India.

In this role, you will design, simulate, test, and optimize innovative LEO-PNT signals, ensuring global precision, robustness, and resilience. You will work at the intersection of signal design, system engineering, and performance validation, contributing to the core architecture of VyomIC’s constellation.

Key Responsibilities

• Development of MATLAB-based GNSS signal generation and simulation models covering PRN codes, navigation data, pilot/data components, carrier modulation, and key signal parameters.
• Characterization and simulation of GNSS signal multiplexing schemes, including power allocation, spectral characteristics, cross-correlation, and interaction between signal components.
• Development of controlled propagation and multipath channel scenarios with configurable path delay, amplitude, phase, Doppler, and number of reflected paths, including the use of ray-tracing techniques and channel modeling tools to characterize realistic propagation environments and evaluate their impact on GNSS/LEO-PNT signal performance.
• Analysis of multipath impact on GNSS acquisition, correlation, code/carrier tracking, pseudorange, carrier phase, and ranging accuracy.
• Development of MATLAB-based receiver simulation and analysis frameworks for GNSS/LEO-PNT, under varying Doppler and channel conditions, along with visualization and trade-off analysis tools to support signal design.

Required Skills & Experience

• B.E./B.Tech./M.E./M.Tech. in ECE or related field with a strong foundation in signal processing and digital communications.
• Strong foundation in digital signal processing (DSP) and digital communications, including correlation, filtering, modulation, sampling, FFT, synchronization, and signal analysis.
• Good MATLAB \Python programming skills, with the ability to develop efficient and reusable functions rather than relying only on built-in toolbox functions.
• Ability to implement signal-processing algorithms from mathematical specifications and optimize them for computational efficiency.
• GNSS signal processing/receiver experience is a plus.
• SDR-based experience in signal generation, capture, processing, or analysis is desirable.

Why Join Us

• Build the future of global navigation - Be the part of the revolution, work on a mission that redefines how the world connects, navigates, and operates in the new age.
• Be part of the founding journey - shape the architecture of a global satellite constellation from the ground up and work directly with the Founding Team at VyomIC.
• Collaborate with High Profile advisors - learn from and engage with senior experts who bring decades of experience.
• High-impact, high-ownership role - your work directly influences real-world systems that demand precision, security, and scale.
• Work alongside a world-class team - collaborate with experts across astrodynamics, signal processing, embedded systems, mission operations, ETC.
• Grow with the mission - as the constellation scales, so do your opportunities for leadership, innovation, and long-term career growth.
