At Sibelco, we believe building a successful career is a two-way journey. We’re looking for individuals who share our values and vision, just as much as you’re seeking a company that aligns with your aspirations. Together, we can shape the future.

Job Description:

Role purpose

Build Sibelco's application-led semiconductor capability and help transform HPQ from a raw-material offering into a strategic technology partnership. The role connects customer process requirements with product engineering, qualification, T&I and manufacturing, enabling Sibelco to influence customer roadmaps, accelerate qualification, strengthen value-in-use arguments and co-develop next-generation HPQ solutions.

Key accountabilities

Customer technology engagement

· Act as a senior technical counterpart to semiconductor fabs, wafer and crucible producers, fused-quartz fabricators and semiconductor equipment OEMs.

· Engage customer process engineering, R&D, quality and technology-roadmap teams at application level rather than limiting discussions to material specifications.

· Lead technically credible conversations across crucibles, fused-quartz consumables, clean thermal applications, etch and other targeted semiconductor applications.

· Build structured engagement plans for strategic ecosystem participants, including equipment makers, fabricators, research institutes and end users.

Application and product development

· Map customer process conditions, failure modes and performance requirements to relevant HPQ material properties.

· Translate application requirements into product targets covering impurity chemistry, hydroxyl content, particle-size distribution, fusion behaviour, bubble formation, devitrification, viscosity and component lifetime.

· Co-lead application-specific product development and validation with T&I, operations, external laboratories and customers.

· Develop value-in-use dossiers that link HPQ characteristics to yield, component life, particles, downtime, process stability and qualification risk.

Qualification and technical problem solving

· Provide application-level input to qualification strategy while Technical Sales & Customer Qualification retains milestone and quality-interface ownership.

· Support root-cause analysis of qualification failures and customer performance issues, converting findings into product, process or specification improvement actions.

· Define testing protocols, acceptance criteria and evidence packages for application validation.

· Capture and reuse qualification learning across customers, applications and regions.

Technology roadmap and competitive intelligence

· Monitor semiconductor process evolution, advanced logic, memory, HBM, advanced packaging and other trends that may change quartz performance requirements.

· Assess application-level threats and opportunities from synthetic silica, silicon carbide, ceramics and other alternative materials.

· Identify defend, grow, explore and no-go application zones based on technical fit, qualification barriers and value creation.

· Provide technical insight to long-range HPQ product and capacity roadmaps.

Knowledge and capability building

· Create and maintain a central application knowledge repository combining analytical, modelling, laboratory, qualification and customer information.

· Publish internal application guides, customer-facing technical papers and training materials.

· Coach Strategic Account Sales, Technical Sales, T&I and operations teams in semiconductor applications and customer process requirements.

· Help recruit and develop additional application engineers as customer demand and the co-development pipeline scale.

Experience and qualifications

Education

· Master's degree required; PhD preferred in Materials Science, Chemical Engineering, Semiconductor Engineering, Physics, Ceramics, Glass Science or a related discipline.

Professional experience

· Typically 10 to 15 years of relevant experience in semiconductor equipment, device manufacturing, process integration, semiconductor materials, fused quartz or high-purity materials.

· Demonstrated experience translating process or device requirements into material or component specifications.

· Experience with customer qualification, change control, failure analysis and cross-functional technical problem solving.

· Credibility engaging technical leaders within equipment OEMs, fabs, wafer producers, crucible manufacturers or quartzware fabricators.

· Experience leading technical work across multiple regions and organisational boundaries.

Preferred industry backgrounds

· Semiconductor equipment or process technology companies such as Lam Research, Applied Materials, Tokyo Electron, Kokusai, ASM or comparable organisations.

· Device, foundry or memory manufacturers such as Intel, TSMC, Samsung, Micron or comparable organisations.

· Quartz, crucible or materials companies such as Heraeus, Momentive, QSIL, SUMCO, Shin-Etsu or comparable organisations.
