Thermal Analysis Engineer

We are looking for a Thermal Analysis Engineer to own thermal analysis and thermal-fluid modelling of rocket engines, propulsion systems, tanks, feed systems, avionics and launch-vehicle subsystems. This is a hands-on engineering role where analysis is expected to directly influence hardware design, testing and qualification.

Responsibilities

• Perform steady-state and transient thermal analyses of launch-vehicle and propulsion hardware.
  

• Develop thermal models at component, subsystem and system levels.
  

• Perform heat-transfer analysis involving:Conduction, Convection, Radiation, Conjugate heat transfer, Thermal-fluid networks
  

• Develop 0-D/1-D thermal resistance and thermal-fluid network models for system-level involving multiphase analysis.
  

• Perform thermal analysis of cryogenic propellant systems including tank heat leak, stratification, boil-off and self-pressurisation.
  

• Perform thermal analysis of rocket engine cooling systems
  

• Perform thermal trade studies and recommend design solutions considering temperature limits, mass, performance and manufacturability.Determine component and system-level thermal margins.
  

• Generate thermal boundary conditions and temperature fields for structural and thermo-mechanical analyses.
  

• Support selection and sizing of insulation, radiation shields, heat sinks, heat straps and other thermal-control solutions.
  

• Support thermal test planning, instrumentation selection and test-data analysis.
  

• Investigate thermal anomalies and failure mechanisms and recommend corrective actions.
  

• Develop engineering tools and automate analysis workflows using Python, MATLAB or equivalent.
  

• Prepare thermal analysis reports, design-review material and verification documentation.
  

• Work closely with propulsion, structures, fluids, aerodynamics, avionics, manufacturing and test teams.
  

Requirements

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

• 2-6 years of relevant experience in thermal analysis, aerospace, propulsion, turbomachinery, cryogenics or other high-performance engineering applications.
  

• Strong fundamentals in: Heat Transfer, Thermodynamics, Fluid Mechanics, Radiation, Numerical Methods
  

• Experience developing and interpreting thermal models.
  

• Ability to translate physical systems into appropriate thermal networks and boundary conditions.
  

• Strong analytical and problem-solving skills.
  

• Ability to independently own an analysis problem from problem definition through design recommendation and closure.
  

• Experience with open-source or internally developed tools is preferred :
  - OpenFOAM
  - Code_Aster / Salome-Meca
  - Python-based thermal-network solvers
  - GNU Octave
  - Custom finite-difference / finite-volume solvers
