Level of experience:  Junior

RINA is currently recruiting for a Thermal Analysis Engineer to join its office in Roma within the Aerospace & Defence Division.

Mission 
We are looking for a Thermal Analysis Engineer to support defense-sector programs in Rome. The selected candidate will focus on the analysis and development of thermal solutions for complex assemblies, ensuring compliance with military standards and project requirements. 

Shape 

Activities 

  • Plan and perform steady-state and transient thermal analyses on complex mechanical assemblies (e.g., shelters, racks, integrated units). 

  • Define thermal requirements and specifications, boundary conditions, load cases, and acceptance criteria. 

  • Build, calibrate, and validate thermal models (e.g., conduction, convection—forced/natural—, radiation) using one of the following software Ansys Suite, FloTHERM, or FloEFD. 

  • Propose and assess thermal mitigation solutions (e.g., heat sinks, TIMs, ventilation/airflow strategies, insulation). 

  • Collaborate with multidisciplinary teams to support environmental qualification activities in accordance with applicable MIL standards. 

  • Document results, assumptions, and recommendations; support design reviews and the implementation of approved changes. 

Shape 

Main Responsibilities 

  • Execute and report thermal simulations for complex assemblies. 

  • Define technical specifications and acceptance criteria related to thermal performance and compliance. 

  • Ensure adherence to military environmental standards (MIL) relevant to thermal performance. 

  • Use Ansys Suite, FloTHERM, or FloEFD for model setup, meshing (thermal), solution, and post-processing. 

  • Provide clear, decision-oriented documentation and participate in design reviews. 

  • Coordinate with design teams to implement thermal recommendations into CAD and product baselines. 

Shape 

Expertise 

  • Master’s degree in Mechanical or Aeronautical Engineering. 

  • Minimum 3 years’ experience in thermal analysis and thermomechanical solution development for complex assemblies. 

  • Knowledge of MIL standards applicable to environmental qualification in the defense domain. 

  • Proficiency in at least one simulation software: Ansys Suite, FloTHERM, or FloEFD. 

  • Familiarity with PLM systems (e.g., Windchill) and CAD tools (CREO, CATIA) is considered a plus. 

  • Strong analytical skills, attention to detail, and ability to communicate technical results to nonspecialists.
