About Rekise Mar

ine
Rekise Marine is building autonomous ships and submarines that operate in the world's most hostile environments. We're executing India's flagship autonomous submarine project the Jalkapi XLAUV on order from the Indian Navy. This is an unmanned submarine weighing over 20 tons that can travel 5,000+ kilometers autonomously and operate in the ocean for 30+ days at a t

ime.We're creating some of the largest autonomous robots in the world, machines with direct impact on the global economy and national security. While autonomous cars in India may still be a dream, autonomous ships and submarines are already a reality, and it is possible to build for the world from In

dia.

Th

e Role
We're seeking a Senior Robotics Engineer to build the simulation and digital twin infrastructure for our autonomous submarine program. You'll create high-fidelity virtual environments where we can test, validate, and accelerate the development of autonomy algorithms before they ever touch the ocean. From modeling hydrodynamics and sensor physics to building full-vehicle digital twins, your work will be the foundation that enables rapid iteration on a platform where real-world testing costs millions and takes months t
