Group: Signal Design (SDG)

Summary

Location: Bengaluru

Job type: Full time

Work Policy: 100% in-office

Joining Date: Immediately

Minimum Experience: 1-2 yrs (can be hands-on academic experience as well)

About the Role

We are looking for a highly motivated GNSS Authentication & Security Engineer to join our team at VyomIC, where we are building the next-generation global LEO-PNT satellite constellation from India.

In this role, you will design, analyze, simulate, and validate authentication and encryption mechanisms for LEO-PNT signals and navigation services, with a focus on protecting PNT data against spoofing, unauthorized access, and signal manipulation. You will work at the intersection of GNSS security, cryptographic techniques, signal design, receiver algorithms, and system-level performance validation, contributing to the development of secure and resilient PNT services for VyomIC's constellation.

Key Responsibilities

Study existing GNSS authentication and encryption techniques, including OSNMA, TESLA-based schemes, digital signatures, MACs, and encrypted spreading/signals.
Define the security requirements and threat model for VyomIC's LEO-PNT signals, focusing on spoofing, navigation-message forgery, replay, and unauthorized access.
Evaluate and recommend suitable authentication architecture for the LEO-PNT navigation message.
Design how authentication data, keys, signatures/MACs, and associated metadata can be incorporated into the navigation message structure with minimal impact on data rate and TTFF.
Develop MATLAB/Python simulations for authentication generation, transmission, verification, latency, overhead, and failure cases.
Analyze security-performance trade-offs including message overhead, computational complexity, authentication latency, false acceptance/rejection, and receiver resource requirements.

Required Skills & Experience

B.Tech/M.Tech in Computer Science, ECE, EE, Communications, Cybersecurity, or related fields.
Strong fundamentals in cryptography, authentication, secure communications, and cybersecurity.
Knowledge of MACs, digital signatures, hashing, encryption, key management, and broadcast authentication schemes.
Good Python/C/C++ programming skills; MATLAB experience is a plus.
Understanding of GNSS/PNT systems and navigation signals is an advantage.
Prior experience with GNSS signal authentication, secure navigation, or GNSS receiver systems is a strong plus.

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.
