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.
