ABOUT US
At AnduraX, we’re building India’s first private Re-entry vehicle designed to fly to space, carry experiments and payloads, and return them safely to Earth. We believe the future of space isn’t just about going farther; it’s also about coming back safer. By building a platform that can fly frequently, recover gently, and serve a wide range of commercial and defence needs, we’re opening doors to a space-powered industrial future. As part of our growing team, you will gain direct experience working on multidisciplinary flight systems that integrate aerodynamics, avionics, guidance, propulsion, structures, recovery systems, and mission operations.
ROLE OVERVIEW
As a Guidance, Navigation & Control (GNC) Engineer, you will lead the development, validation, and deployment of the complete GNC architecture for AnduraX's reusable re-entry vehicle. You will be responsible for designing autonomous flight algorithms covering all mission phases, from high-altitude release and atmospheric glide to parafoil recovery, precision landing, and future orbital re-entry missions. Working closely with Systems Engineering, Aerodynamics, Avionics, Flight Software, Structures, and Test teams, you will develop robust guidance, navigation, estimation, and control algorithms that ensure safe, reliable, and repeatable autonomous flight. You will own the complete algorithm development lifecycle, from mathematical modelling and simulation to hardware integration, flight validation, and post-flight performance analysis.
This role demands deep expertise in flight dynamics, estimation, control theory, autonomous systems, and real-world flight testing. You will play a critical role in enabling India's first privately developed reusable re-entry vehicle.
This role combines office-based engineering with laboratory, workshop, integration, and field-test activities. Candidates should be comfortable transitioning between analytical work, software development, hardware integration, and outdoor flight operations.
