Job description

Vattenfall is looking for a Senior Mechanical Engineer with broad Drivetrain and Yaw system knowledge for our Business Area Wind within the WTG Systems Engineering department. If you are interested in a job with potential, possibilities, and want to be a part of an organization with special focus on Renewables, you may be the person we are looking for. You will be collaborating with colleagues located across the various European locations.

The WTG Systems Engineering department is the technical WTG knowledge centre within Business Area Wind, setting the standards and guidelines as well as being embedded within our projects, both through the development and implementation phase and later taking over the support to the operations as backoffice. On the technical level the department covers all engineering aspects of the WTG.

The challenge

As a Senior Mechanical Engineer in WTG Engineering, Operations Technology, you will provide technical expertise and strategic support for Mechanical components including the Drivetrain and Yaw systems across Vattenfall's operational wind portfolio.

You will be a trusted technical partner, strengthening collaboration, knowledge sharing, and an inclusive working environment. Working closely with engineering, asset management, operations, and external suppliers, you will translate specialist expertise into coordinated solutions across the organization.

The role combines fleet-level asset management with hands‑on technical problem‑solving. You will support the mechanical systems throughout their operational lifecycle by shaping maintenance strategies, defining inspection and repair requirements, improving performance, managing technical risk, and evaluating new technologies.

Continuous improvement is at the core of this position. You will identify opportunities to enhance maintenance strategies, improve asset performance, reduce operational risk, and deliver greater long‑term value from our renewable assets.

What You Will Do

This role offers a unique opportunity to move beyond individual projects or site‑level support and take a fleet‑wide perspective on Mechanical components including Drivetrain and Yaw systems. As one of Vattenfall's technical authorities in this field, you will influence maintenance strategies, risk management, and technology adoption across a diverse portfolio of wind assets throughout the operating lifecycle, including:

• Develop and optimize maintenance strategies and asset management plans
• Lead technical investigations and Root Cause Analyses (RCA)
• Assess technical risks and support data‑driven decision‑making across the fleet
• Define technical requirements for inspections, repairs, monitoring systems, and maintenance activities
• Support supplier selection, contract development, and technical performance evaluations
• Maintain OPEX assumptions, budgets, and cost models
• Evaluate, test, and implement innovative technologies incl. inspection and repair solutions
• Review technical proposals for component purchases and refurbishments
• Share lessons learned and contribute to continuous improvement initiatives across the organization

Success in this role means helping to reduce operational risk, improve technical availability, optimize maintenance costs, and ensure technical learnings are effectively transferred across Vattenfall's wind fleet.

The position includes occasional international travel to wind farms, supplier facilities, technical workshops, and investigations. Expected travel activity is typically less than 25 days per year.

Qualifications

What we are looking for

• Strong knowledge of Mechanical failure mechanisms, inspection, and repair methodologies
• Experience in leading technical investigations and Root Cause Analyses
• The ability to communicate complex technical topics clearly to both technical and non‑technical stakeholders
• Experience in working effectively across multidisciplinary teams and influencing technical decisions
• Professional proficiency in written and spoken English

It Will Be An Advantage If You Also Have

• Offshore wind experience
• Experience developing or optimizing maintenance strategies for Drivetrains and Yaw systems
• The ability to adapt effectively to changing operational environments, procedures, and digital tools
• Familiarity with IEC standards relevant to Drivetrain, Yaw systems, and other mechanical systems
• Experience working with OEMs, service providers, certification bodies, and other technical stakeholders

What We Offer

We offer a challenging and rewarding role in an international and collaborative environment where technical expertise is highly valued, where you will have the opportunity to:

• Influence Mechanical reliability and innovation across a large and diverse renewable energy portfolio
• Take a key expert role within Offshore Engineering and contribute to strategic technical decisions
