Create and maintain parametric CAD models and detailed drawings for turbine components (blade root, spar cap, shell, root inserts, hub, pitch systems) that are manufacturable, cost-effective, and compatible with supplier constraints and tooling methods.
Define and optimise rotor geometry, twist, chord distribution, airfoil selection, and planform to maximize annual energy production (AEP) while controlling extreme and fatigue loads across expected wind climates and turbulence intensities.
Perform aeroelastic simulations and coupled aero-servo-elastic analyses (e.g., FAST, Bladed, OpenFAST) to evaluate dynamic response, stability, and interaction effects between aerodynamics, structural flexibility, and control systems, and implement design mitigations as required.
Lead and coordinate blade and component certification activities, preparing technical documentation, load cases, test plans, and supporting third-party certification bodies during design review, prototype testing, and type certification.
Collaborate cross-functionally with control systems engineers to ensure rotor and drivetrain compatibility with pitch, yaw, and power control strategies, including design-for-control considerations and control load cases.
Specify materials, layups, and manufacturing processes for composite blades and structural components, working closely with suppliers to validate material properties, resin systems, core materials, and bonding processes in prototype and production phases.
Develop and refine fatigue life prediction workflows and operational load spectra, implementing damage accumulation methodologies and durability margins to guarantee design life under expected operational and extreme events.
Lead root/bolt stack and hub interface design, fatigue-critical fastener selection, and bearing/hub load path assessment to ensure reliability and maintenance accessibility under combined static, dynamic, and thermal loading.
Generate and review bill of materials (BOM), tolerance stacks, and manufacturing drawings, ensuring components meet assembly, transport, lifting, and installation requirements for onshore and offshore scenarios.
Execute noise prediction assessments and blade tip design iterations to meet acoustic performance targets and regulatory requirements in proximity-sensitive sites, balancing noise vs. energy yield trade-offs.
Support wind farm layout and micro-siting teams by providing turbine design inputs for wake modeling, power curve adjustments, and turbine spacing recommendations that impact AEP and loads across the farm.
Conduct design reviews, design failure mode and effects analysis (DFMEA), and root-cause investigations following prototype testing, field failures, or manufacturing non-conformities; propose and validate corrective design actions to reduce risk and lifecycle cost.
Produce consolidated load and performance reports, test procedures, and acceptance criteria for prototype testing (static, fatigue, modal) and field validation trials; coordinate on-site instrumentation campaigns and data analysis.
Manage supplier and vendor technical interfaces, lead design transfer activities, and support supplier qualification, tooling validation, and production ramp-up to ensure design intent is maintained through manufacturing.
Drive continuous improvement through post-installation performance analysis, warranty data review, and O&M feedback to iterate blade and component designs for improved reliability and lower LCoE (Levelized Cost of Energy).
Maintain up-to-date knowledge of industry standards, changes to IEC/GL guidelines, grid codes, and environmental regulations; incorporate compliance requirements into design baselines and certification strategies.
Mentor junior designers and engineers, establish best-practice design procedures, and contribute to the development of internal design standards, templates, and libraries to accelerate scalable turbine design.
Support commercial bid and project engineering activities by producing technical write-ups, feasibility assessments, high-level load cases, and design basis documentation for proposals and tenders.
Participate in cross-disciplinary technical risk assessments and project gating, presenting technical trade-offs, cost implications, and schedule impacts to stakeholders and program management.
Oversee the integration of sensors, lightning protection, and blade heating or de-icing systems into blade and rotor designs, ensuring electrical, structural, and aerodynamic compatibility.
Coordinate with logistics, installation, and O&M teams to ensure blade and component designs meet transport, crane, and on-site assembly constraints for coastal, remote, and offshore deployment.
Evaluate new technologies and materials (e.g., new polymer matrices, recyclable composites, hybrid materials) for potential use in blade and structural components, steering pilot projects and validation testing.

Secondary Functions

Support prototype testing programs by preparing instrumentation plans, supervising test set-up, and analyzing test data to validate models and close the loop on design assumptions.
Provide subject-matter-expert input to the organization’s technical roadmap for rotor and blade development, identifying opportunities for cost reduction, reliability improvements, and performance gains.
Collaborate with business development and project teams to translate client technical requirements into design deliverables and risk mitigations during early project stages.

Contribute to cross-functional agile/scrum processes for product development, participating in sprint planning, backlog grooming, and design reviews to deliver prioritized features.
Respond to ad-hoc technical requests from operations and service teams, providing analysis and design options to expedite repairs, retrofits, or uprates.
Maintain technical documentation, CAD libraries, and version control practices to ensure traceability and efficient handover between R&D, engineering, and manufacturing teams.
