Thermal Analysis Engineer

Join to apply for the Thermal Analysis Engineer role at RINA

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.

Key Accountabilities

• 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.
• 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.

Education

• Master’s degree in Mechanical or Aeronautical Engineering

Qualifications

• 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.
