About the role

Thermal Protection Systems Engineer designing ablative thermal protection systems for aerospace. Join Destinus to develop cutting-edge UAVs for the defense industry.

Responsibilities

**What You´ll Do**
Design and size ablative thermal protection systems for rocket motors, propulsion components, and high-temperature structural assemblies
Perform transient thermal analyses including ablation, pyrolysis, char layer evolution, and bondline temperature prediction
Develop coupled thermo-mechanical FEM models to evaluate insulation integrity, thermal stresses, and structural–thermal interactions
Select and characterize ablative materials such as EPDM-based insulators, carbon–phenolics, and high-temperature composites
Validate analysis models against test data including recession measurements, thermocouple profiles, and subscale firing results
Define, support, and participate in TPS-related test campaigns, including material testing, flame exposure, and propulsion firings
Translate thermal and mechanical analysis results into actionable design requirements, TPS layouts, and manufacturable solutions
Produce technical documentation including analysis reports, TPS specifications, drawings, and verification plans
Work closely with propulsion, materials, and manufacturing teams to ensure TPS integration aligns with system requirements and mitigates thermal and mechanical risks
Support non-conformance assessments, failure investigations, and updates to TPS design or processes based on test outcomes

**What You’ll Need**
Bachelor’s or Master’s degree in Aerospace, Mechanical, or Materials Engineering.
3–7 years of experience in ablative TPS, high-temperature insulation, or thermal protection design.
Hands-on experience with ablative materials, transient thermal analysis, or pyrolysis/ablation modeling.
Familiarity with thermo-mechanical FEM tools (ANSYS, Abaqus, COMSOL) and TPS integration best practices.
Experience with high-temperature or propulsion testing, including data interpretation and correlation.
Strong analytical and documentation skills, able to interpret complex thermal data, produce clear reports, and justify design decisions.
Willingness to travel between Swiss facilities (up to 20%).
Comfortable working across disciplines. Propulsion, materials, manufacturing, and test engineering.
