Senior Stress Engineer - Composite Structures

Heart Aerospace

Gothenburg, Sweden

Your mission

The Senior Stress Engineer will have a critical role in the design, analysis, and optimization of lightweight composite structures, focusing on advanced manufacturing technologies like Automated Fiber Placement (AFP) and Vacuum-Assisted Resin Transfer Molding (VARTM).

Key responsibilities include but are not limited to:

Perform detailed stress and structural analysis of composite aircraft components such as wings, fuselage sections, empennage, and secondary structures, ensuring all analysis meets aerospace certification standards.
Use advanced finite element analysis (FEA) tools (NASTRAN, Hypermesh) to simulate load conditions and predict structural behavior.
Work with design teams to optimize composite structures for performance, manufacturing and weight reduction.
Recommend changes to laminate stacking sequences, fiber orientations, and ply layup to meet performance criteria and facilitate Automated Fiber Placement (AFP) or other advanced composite manufacturing processes.
Liaise with design, manufacturing, materials engineering, and quality teams to ensure composite structures are designed and analyzed in accordance with project specifications.
Provide technical guidance during the manufacturing process, addressing composite layup, curing processes (e.g. VARTM), and inspection methods.
Prepare stress reports and documentation for certification authorities.
Support full-scale testing of composite components, including static, fatigue, and environmental tests.
Correlate FEA models with physical test results, refining analysis as necessary.
You will report to the Head Airframe & Interiors and your place of work will be at our main office located in Gothenburg, Sweden.
