Job description

De Havilland Aircraft of Canada is seeking highly skilled and experienced Stress Engineering Specialists to support the structural analysis and certification of both new and existing aircraft programs. The successful candidate will have 10+ years of experience in aerospace stress engineering, with advanced proficiency in Finite Element Modelling (DFEM and GFEM), classical hand calculations, and a wide range of analysis tools and techniques.

This role offers the opportunity to work on high-impact programs, where analytical excellence and engineering judgment are key to ensuring the structural integrity, safety, and regulatory compliance of De Havilland’s aircraft.

Key Responsibilities:

Perform detailed and global finite element analysis (DFEM and GFEM) to support structural design, modifications, and certification.

Execute and validate classical hand calculations for static strength, fatigue, and damage tolerance analysis.

Analyze structural components including fuselage, wings, empennage, nacelles, landing gear attachment areas, and interiors.

Collaborate with Design, Loads, Materials, and Liaison Engineering to ensure structural integrity and manufacturability of designs.

Prepare and review engineering documentation, including stress reports, substantiation packages, and compliance matrices.

Support certification efforts with regulatory agencies (TCCA, FAA, EASA), including coordination with Design Approval Representatives (DARs).

Assist in the development and maintenance of analysis tools, templates, and best practices for stress calculations.

Provide mentorship and technical leadership to junior engineers and analysts.

Qualifications:

Bachelor’s or Master’s degree in Aerospace, Mechanical Engineering, or a related field.

10+ years of progressive experience in aircraft structural stress analysis.

Expertise in FEM tools such as NASTRAN, Patran, HyperMesh, FEMAP, or ANSYS.

Strong experience with DFEM and GFEM modelling, mesh refinement, boundary conditions, and results interpretation.

Proficient in hand calculations using classical methods (Bruhn, Niu, Roark, etc.).

Comfortable using spreadsheets, scripting tools (e.g., Python, MATLAB), and custom calculation tools.

Solid understanding of certification requirements, including fatigue and damage tolerance criteria per FAR/CS Part 25.

Experience preparing substantiation reports and interacting with certification authorities or DERs.

Excellent communication, documentation, and problem-solving skills.

Preferred Qualifications:

Familiarity with legacy aircraft structure and modification/repair analysis.

Experience in weight optimization, composite structure analysis, or crashworthiness is an asset.

Knowledge of PLM systems (e.g. ENOVIA, SmarTeam) and configuration control processes.
