Mechanical Reliability Engineer

We’re Nadara. We work harmoniously with the power of nature and the communities around us to power lifetimes to come. We call our approach ‘living energy’. We don’t just produce renewable energy, we live it – recognising our relationship with the people touched by our business and supporting social, educational, cultural, and environmental initiatives that contribute to the development of the communities we work alongside.

Nadara is an innovative place to work. We work in a stimulating and challenging environment, where every day we explore the unknown with curiosity, make decisions with quality and take action and deliver with courage. For us diversity is a real value, and we encourage connecting different perspectives with respect.

The Mechanical Reliability Engineer will act as a subject‑matter expert in the reliability of mechanical systems and components on wind turbines. They will drive continuous improvement to minimize downtime, enhance performance, and optimize maintenance strategies across the fleet, provide risk‑informed guidance to internal stakeholders and lead the engineering processes that prevent unscheduled major component failures, ensuring the implementation of corrective actions and the definition of major component overhaul processes.

• Mechanical Systems Reliability – Engineering Support
  • 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.
• Root Cause, Reliability & Risk
  • 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.
• Standards, Processes & ECRs
  • 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.
• Spares, Refurbishment & Overhauls
  • 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.
• Budget & Performance
  • Support preparation and management of the Mechanical Reliability activity budget.
  • Propose cost‑effective actions to meet reliability goals.
  • Monitor KPIs to evidence program effectiveness.
• Asset Integrity
  • 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.

This document must be read in combination with the HSQE Management System Manual, which outlines the mandatory HSQE responsibilities and authorities related to this role.

• Wind Turbine Subsystems: Drivetrain (main bearing, gearbox, generator), yaw/pitch systems, couplings, slip rings, and related interfaces.
• RCA & Reliability: RCA methods, FMEA/FMECA; reliability/risk assessments; estimation of failure progression/timelines; RAMS assessment.
• Inspections: Borescope inspection review; evidence‑based acceptance criteria; translation of inspection findings into work orders and ECRs.
• Project & Process: Ability to structure work; creation and maintenance of best practices, procedures, and tools.
• Data & Reporting: Build and interpret reliability KPIs; clear, concise technical reporting for both engineering and non‑technical audiences.

• Organised and methodical; safety‑oriented; results‑focused with persistence and ownership.
• Confident, articulate communicator; excellent written communication.
• Teamwork and the ability to direct different maintenance and other operational activities.
• Relationship building across internal/external stakeholders; cross‑cultural awareness and sensitivity.

• BSc/MSc in Mechanical Engineering (or closely related discipline).
• Demonstrable experience in the wind energy industry (5 years) focused on maintenance/reliability of mechanical systems within wind turbines.

• Demonstrable experience with reliability engineering tools (e.g., FMEA/FMECA, RCA, FTA).
• Experience with CMMS and SCADA Systems.
• Condition Monitoring Techniques (vibration analysis, oil analysis, thermography).

• English (required). Additional languages (French/Spanish/Portuguese/Italian) advantageous given fleet footprint and supplier base.
