Senior Materials Engineer Sulzer Ltd

At Sulzer, we keep the world s most critical rotating equipment performing at its best combining deep engineering expertise with advanced repair technologies to extend the life, reliability, and efficiency of gas turbines, steam turbines, compressors, and aero derivative turbine systems. Whether based in Venlo, Aberdeen, or Abu Dhabi, you ll join a global network recognised for its excellence in hot gas path component repair, turbine overhauls, and industry leading aeroderivative capability. Our advantage lies in our unique blend of independent OEM agnostic expertise, decades of specialised turbine engineering, and the ability to deliver rapid, high quality solutions that keep critical assets operating longer, cleaner, and more efficiently.

Due to an upcoming retirement, we are seeking a Senior Materials Engineer with deep expertise in hot end rotating components and advanced nickel based superalloys used in high temperature aerospace and turbomachinery applications. The ideal candidate will bring strong insight into material behaviour under extreme thermal and mechanical conditions, along with a proven ability to diagnose and prevent complex failure modes across critical rotating hardware.

Key Responsibilities

• Serve as the subject-matter expert for nickel superalloy selection, processing, and performance in hot-section rotating components.

• Lead and support failure investigations, identifying root causes related to fatigue, creep, oxidation, corrosion, casting defects, and high temperature degradation mechanisms.

• Provide technical guidance throughout casting process development, including alloy melt practice, grain structure control, defect analysis, and supplier capability assessments.

• Drive and support cast part qualification, including specification development, material property validation, microstructural evaluation, and buy-off of supplier manufacturing routes.

• Collaborate closely with design, quality, and suppliers to ensure materials and processes meet performance, reliability, and regulatory requirements.

• Use metallurgical analysis tools (e.g., SEM/EDS, optical microscopy, fractography, mechanical testing) to assess component condition and ensure product integrity.

Qualifications

• Master s degree or PhD in Materials Science, Metallurgy, Mechanical Engineering, or a related advanced discipline.

• Advanced knowledge of nickel based superalloys, high temperature materials science, and rotating component lifing considerations.

• Extensive hands-on experience with hot-end failure analysis across aerospace, industrial gas turbine, or similar high performance sectors.

• Demonstrated success in casting process oversight and supporting full lifecycle cast part qualifications.

• Strong communication skills and the ability to work cross functionally with engineering, operations, suppliers, and leadership teams.
