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 growth opportunities.
