Company Description:

Stratum Defense Technology is an indigenous Indian defence-technology company building autonomous systems across naval, air, and land domains. We are hiring a propulsion and propeller design engineer to own thrust-producing systems across our underwater, airborne, and turbine-propelled platforms, from blade and core geometry through to validated hardware.

We are headquartered in Current Delhi.

Role Description
You will own the propulsor. This is the design-authority seat for the thrust-producing system on our underwater vehicles: you define the pump-jet propulsor geometry from first principles, predict how it behaves, and defend those numbers against measured data.

This is a design seat, not a modelling one, and it sits above the hydrodynamics and Computational Fluid Dynamics (CFD) analysis function rather than duplicating it. You set the geometry; the analysis lane characterises what you have set. The engaging part of the role is the closed loop: the gap between a lifting-surface prediction, a CFD solution,



and a cavitation-tunnel image is where the real design work lives, and on an underwater vehicle that loop is driven as hard by acoustic signature as by efficiency.

What you will do
Own Pump-Jet Propulsor (PJP) and marine propeller design from first principles: rotor and stator design, duct shaping, blade geometry generation and parameterisation, and off-design behaviour
Predict performance across thrust, torque, and efficiency, in open water and behind the hull, at design point and across off-design and transient conditions
Run rotating-machinery CFD and interpret it against theory, not just produce it
Treat acoustic signature as a first-order design driver, and analyse and suppress cavitation inception
Define and execute validation campaigns: towing tank and cavitation tunnel, including test-plan definition and instrumentation
Correlate prediction against measured data and own the design changes that follow when the two disa
