Associate Scientist - Propulsion (Bipropellant)

We are looking for a Propulsion Engineer responsible for the design, development, testing, integration, and qualification of bi-propellant propulsion systems for aerospace applications. The role requires hands-on involvement in laboratory and test-stand work (cold-flow through hot-fire), system integration, data analysis, and technical documentation, while working closely with multidisciplinary engineering teams.

Qualifications

• B.E./B.Tech or M.E./M.Tech in Aerospace Engineering, Mechanical Engineering or a related discipline.

• 2+ years of relevant experience in propulsion system design, testing, hands-on hardware work.

Responsibilities

• Assist in the design and development of bi-propellant propulsion subsystems and associated components (injectors, feed systems, valves, thrust chambers).

• Support propulsion system architecture development, component selection (valves, regulators, sensors etc.), and performance evaluation for self-pressurizing propellant systems.

• Perform system-level and component-level cold-flow and hot-fire testing and qualification activities.

• Assist in assembly, integration, and checkout of propulsion subsystems for experimental and pre-flight/flight applications.

• Support hot-fire testing of bi-propellant thrusters across the product family.

• Perform instrumentation setup, sensor integration (pressure transducers, load cells, thermocouples), calibration, and test equipment handling.

• Conduct test preparation, execution, and troubleshooting, including feed-system and valve-actuation control.

• Perform post-processing and analysis of propulsion test data.

• Maintain technical documentation, test reports, qualification records, and configuration documentation.

• Coordinate with mechanical, electrical, avionics, manufacturing, and systems teams for subsystem integration.

• Follow laboratory safety procedures and quality standards during testing operations, including safe handling of pressurized oxidizer/fuel systems.

Requirements

• Sound understanding of thermodynamics, fluid mechanics, gas dynamics, heat transfer, and rocket propulsion fundamentals.

• Experience working on bipropellant/liquid propulsion systems, injector design, and feed-system architecture.

• Worked on rocket engine plumbing and P&ID development/interpretation.

• Hands-on experience with fluid systems, including high-pressure fluid systems, valves, regulators, and pressurization/feed systems.

• Proficient in CAD (SolidWorks), CAE, and CFD (ANSYS Fluent).
