Description

The Mechanical Reliability Engineer will serve as the subject‑matter expert for the reliability of mechanical systems and components on wind turbines. The role drives continuous improvement to minimise downtime, enhance performance and optimise maintenance strategies across the fleet while providing risk‑informed guidance to internal stakeholders. It also leads engineering processes that prevent unscheduled major component failures, implements corrective actions and defines major component overhaul processes.

• Assess the condition of mechanical systems and provide expert guidance to internal and external clients.
• Oversee drivetrain components within partial‑scope contracts; define actions to return/maintain assets in service.
• Support end‑of‑contract inspections (defect classification and risk‑informed failure timelines).
• Collaborate with Predictive Maintenance Team to ensure all CMS alerts (vibration, lubrication) are investigated, escalated, and solved to avoid unscheduled major component failures.
• Partner with Inspections & Repairs Team to scope/execute borescope (gearbox) inspections and translate findings into corrective actions.
• Lead/participate in Root Cause Analysis (RCA) and Failure Mode and Effect Analysis (FMEA/FMECA); implement corrective and preventive actions.
• Conduct fleet‑wide component‑level condition and reliability assessments and propose strategies to achieve reliability and reduce failure risk.
• Create, review and implement Engineering Change Requests (ECRs).
• Develop and maintain Engineering Best Practices, processes, checklists, and tools to improve condition assessment, optimize maintenance strategies, and ensure operational reliability.
• Contribute to spare‑parts stock strategies based on fleet condition and risk assessment.
• Collaborate with Stock Management and Asset Management and approved refurbishment vendors to define/implement repair policies, framework contracts, and new overhaul routes for major components.
• Support inbound/outbound quality checks and technical disposal of damaged components.
• Support preparation and management of the Mechanical Reliability activity budget.
• Propose cost‑effective actions to meet reliability goals.
• Monitor KPIs to evidence program effectiveness.
• Provide risk‑informed guidance to internal stakeholders and lead engineering processes that oversee corrective actions on the structural and mechanical integrity of wind turbine components through defining maintenance plans and repairs strategy.

Requirements

The position requires deep knowledge of wind turbine subsystems such as drivetrain, yaw/pitch systems, couplings and slip rings, as well as expertise in root‑cause analysis, FMEA/FMECA and reliability risk assessments. Experience with inspections—including borescope reviews and evidence‑based acceptance criteria—and the ability to translate findings into work orders and engineering change requests are essential. Strong project and process skills, data‑driven KPI reporting and the capacity to communicate technical information to both engineering and non‑technical audiences are also required.

Candidates should hold a BSc or MSc in Mechanical Engineering (or a closely related discipline) and have at least five years of demonstrable experience in the wind energy industry focusing on maintenance and reliability of mechanical systems. Experience with reliability engineering tools (FMEA/FMECA, RCA, FTA), CMMS and SCADA systems, and condition monitoring techniques such as vibration, oil analysis and thermography is desirable. Fluency in English is required; additional languages (French, Spanish, Portuguese or Italian) are advantageous. The role is based in Lisbon, full‑time.
