Job Description
Introduction to the Job

In this role, you will help model and design gas flow from atmosphere to deep vacuum, select appropriate materials, and design cleanliness processes that support vacuum-grade performance in scanner and test-rig environments. The solutions developed in this role directly impact wafer yield, machine availability, and customer productivity.

Scope / Level of Impact

Leads technically complex vacuum and gas-flow work packages, supports hardware projects and lead designers, owns defined architecture or subsystem deliverables, and drives cross-functional alignment with architects, projects, competences, customer support, and research partners. Focuses on ownership of subsystem-level vacuum and gas-flow solutions while developing broader architecture expertise across the Defectivity domain.
Role and Responsibilities

As a Vacuum Systems Engineer in the Defectivity group, you will work closely with Veldhoven machine conditioning Engineers, Defectivity MDU architects and leadership to specify vacuum systems and gas flows in scanners and test rigs. Partner with hardware project teams and lead designers to ensure vacuum and gas-flow requirements are successfully integrated throughout the product development lifecycle. Lead the ASML Wilton Engineer guild for machine conditioning architecture and vacuum systems competence onsite.

• Translate the overall system design into a gas-flow and vacuum architecture that meets system requirements.
• Specify vacuum system components, standards, and procedures and ensure they are properly recorded in Technical Product Documentation (TPD).
• Define, model, and execute qualification tests to verify that the architecture or subsystem performs all specified functions and meets all performance and design requirements.
• Support resolution of particle contamination issues through analysis and specification of flushing and venting procedures.
• Specify pump-down and vent procedures that ensure common flow performance.
• Participate in design reviews for test rigs and support functional integration of architectures or subsystems.
• Execute design of experiments for degassing chambers and components on product and process levels.
• Provide surface particulate and vacuum-grade cleanliness support, hands on troubleshoot escalations, and contribute practical recommendations from analysis.
• Transfer vacuum systems knowledge between ASML units and frequently interact with D&E Delivery Teams, functions, competences, customer support, and research.
• Perform analyses and calculations to predict flow architecture or subsystem functionality, including pressure-drop budgeting, flow budgeting, humidification, and gas purity.
• Take direction from ASML System Architects and principal engineering mentors leading critical large-capital-equipment development efforts.
• Follow EHS policies and proactively identify, communicate, and mitigate safety risks.

Education and Experience

Minimum education and experience expectations vary by job grade. A bachelor's degree in a relevant technical field is required; a master's degree or PhD is preferred depending on role scope, technical depth, and business need.

• BS degree in a technical field and 5+ years of thorough experience; MS or PhD preferred. Education above a BS can compensate for years of experience depending on the candidate.

Skills
Technical and Functional Skills

• Vacuum systems and gas-flow architecture: Ability to specify vacuum systems, gas flows, pump-down and vent procedures, and architecture requirements for scanner and test-rig environments.
• Cleanliness, materials, and contamination control: Knowledge of molecular and particle cleanliness, surface particulate behavior, vacuum-grade cleanliness, materials compatibility, desorption issues, and contamination troubleshooting.
• Analysis, modeling, and testing: Ability to plan and execute tests and DOEs, analyze measurement results, perform pressure-drop and flow budgeting, and use evidence to make practical recommendations.
• Documentation and technical communication: Ability to document standards, procedures, requirements, test evidence, and component specifications in Technical Product Documentation and present findings to varied technical audiences.
• Preferred technical skills: Experience with particle transport in flows, rarefied gas flow, plasma physics, electrostatics, surface science, RGA or other vacuum measurement techniques, and calculations or simulations for gas-flow and particle transport.
• Experience using modeling or simulation tools: to predict gas flow, vacuum performance, contamination transport, or thermal-fluid behavior is highly desirable.
• Demonstrate: strong technical writing and communication skills.

Behavioral and Leadership Skills

• Drives results: Translates technical goals into clear priorities and delivers committed outcomes with quality and ownership.
• Collaborates and communicates effectively: Works across disciplines, suppliers, and stakeholders to align expectations, resolve issues, and transfer knowledge between ASML units.
• Demonstrates self-awareness: Seeks and applies feedback, adapts approach, and improves collaboration in complex or ambiguous environments.
• Values differences: Respects and integrates diverse perspectives to strengthen decision quality and inclusive execution.
• Builds effective teams: Establishes clear goals, roles, accountability, and ways of working while coaching others as applicable.
• Drives vision and purpose: Connects technical direction to business priorities and helps teams stay focused through ambiguity and change.
• Ownership and adaptability: Demonstrates high energy, self-motivation, quick learning, flexibility, and the ability to handle multiple projects and tasks concurrently with minimal guidance.
