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 New 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
