Day-to-Day responsibilities include:

  •  What You’ll Do
    • Develop and optimize solid propellant chemical compositions based on required propulsion performance.
    • Carry out propellant preparation, mixing, casting, curing, and processing as per approved procedures.
    • Characterize propellant properties including density, burn behaviour, mechanical properties, and thermal characteristics.
    • Perform rocket motor performance calculations, including thrust, chamber pressure, burn time, total impulse, and specific impulse.
    • Conduct internal ballistics calculations and evaluate grain geometry and burning characteristics.
    • Perform rocket nozzle calculations and sizing, including throat area, expansion ratio, exit area, and expected nozzle performance.
    • Support selection and analysis of nozzle materials, insulation, and thermal protection systems.
    • Perform preliminary thermal and structural calculations for motor and nozzle components.
    • Support design and development of ignition systems and motor interfaces.
    • Prepare technical specifications, engineering calculations, test plans, BOMs, and technical reports.
    • Support static firing tests, instrumentation, data acquisition, and post-test performance analysis.
    • Correlate theoretical calculations with experimental test results and recommend design improvements.
    • Investigate propulsion-system failures and support root-cause analysis and corrective actions.
    • Coordinate with mechanical, manufacturing, testing, and materials teams for prototype development.
    • Maintain proper documentation, traceability, safety procedures, and configuration control for propulsion activities.
  • How we Evaluate you

  • You will be given a real propulsion problem (not textbook questions)
  • You may be asked to design a motor, estimate thrust, and justify choices
  • We look for practical thinking + build capability, not just equations
