Principal Engineer - Mechanical Structures & Dynamics
Job Description Summary As a Principal Engineer - Mechanical Structures & Dynamics, you will be a technical reference within our structural engineering community, providing deep expertise in structural analysis, dynamics, and mechanical design for wind turbine nacelles. You will work across the full engineering lifecycle, from pre-conceptual design through analysis and validation, covering sheet-metal structures, welded and bolted assemblies, and composite components. Beyond your own technical contribution, you will help raise the capability of the wider team through mentoring, coaching, development of new engineering methodologies, and technical guidance. This is a leadership role for an experienced engineer who can challenge assumptions, develop new methods, and partner with CTHs, design teams, suppliers, and cross-functional stakeholders to deliver safe, high-quality, and compliant products.
Job Description
Essential Responsibilities

Lead complex structural analysis and engineering activities, using FEA/ANSYS to assess strength,



dynamics, fatigue, and structural integrity.
Develop and improve calculation methodologies and engineering approaches for challenging structural problems.
Provide technical guidance on structural design, challenging assumptions and ensuring robust engineering decisions from concept through validation.
Mentor and coach engineers, sharing knowledge and strengthening technical capability across the team.
Work closely with design, manufacturing, testing, suppliers, and other engineering functions to deliver robust structural solutions.

Qualification / Requirements

Master's degree in Mechanical, Structural, Aerospace Engineering, or a related field.
Extensive hands-on experience in structural engineering, including both mechanical design and structural analysis.
Deep expertise in FEA and structural dynamics, ideally with ANSYS.
Experience with large fabricated structures, including sheet
