Introduction to the role

ASML US, including its affiliates and subsidiaries, bring together the most creative minds in science and technology to develop lithography machines that are key to producing faster, cheaper, more energy-efficient microchips. We design, develop, integrate, market and service these advanced machines, which enable our customers - the world’s leading chipmakers - to reduce the size and increase the functionality of their microchips, which in turn leads to smaller, more powerful consumer electronics. Our headquarters are in Veldhoven, Netherlands, and we have 18 office locations around the United States including main offices in Chandler, Arizona, San Jose and San Diego, California, Wilton, Connecticut, and Hillsboro, Oregon.

Job Mission

The mission of the Mechanical Design Engineer at ASML is to create incredible products using the latest technology and manufacturing techniques, while collaborating with a team of dedicated and high-performing technical experts. Quality is at the forefront of the engineering requirements for this group and we strive to provide the best performing and highest quality products within the scope of the program schedule.

Role and responsibilities

Assists with an assigned light source sub-system project through direct technical advice, specifications/design, approvals, and collaboration with Development Engineering team.

Assists in providing a broad mechanical engineering design background and performs mechanical engineering analysis (stress, vibrations, thermal), design for control and distribution of inert and hazardous gases, air and water handling for thermal management of equipment and enclosures, large enclosure design, electrical component packaging, mechanical structural mounts and fixtures, design for manufacturability in low volume products, and design for configuration management.

Assists in generating module or system concepts to meet product requirements.

Assists in performing detailed design and component layout for new or improved subsystems.

Assumes engineering responsibility for component and subassembly test development, data acquisition, analysis, and reporting.

Performs tolerance analysis at system and subsystem level.

Performs analytical analysis for thermal and structural components and sub-modules.

Assists in project planning including key deliverables, timeline, and budget.

Works with other Engineers analysts and CAD Designers for prototype and pilot detailed design.

Supports driving full documentation of design including, BOM, technical drawings, test plans and procedures.

Responsible for the research and selection of new suppliers with potential for turn-key provision of key subsystems. Responsible for providing technical expertise in the core technology area of the potential suppliers to reveal best design path and performance.

Interacts closely with development engineers, scientists, suppliers, and QA to resolve quality issues.

Advises Project Leads with technical expertise

Advises and mentors lower level mechanical design engineers

Presents technical data to a broad audience

Possible travel domestic / international (10%)

Performs other duties as assigned.

Education and experience

Requires minimum of a Bachelor’s degree in Mechanical Engineering with a minimum of twelve (12) years of relevant work experience. Can consider a Master’s degree in Mechanical Engineering with a minimum of ten (10) years of relevant work experience.

Ability to translate, statistically analyze data, and effectively report problems through written and/or graphical formats.

Skilled in designing complex parts and / or assemblies with associated calculations and backup data.

Experience working with cross-functional teams and able to work on multiple tasks simultaneously.

Ability to delegate work as needed.

Experience with tolerance analysis at system and subsystem level, with the ability to generate a tolerance analysis as a deliverable for presentation to a technical group. This analysis should include, thermal, manufacturing and environmental inputs.

Working knowledge of engineering materials i.e. ferrous and non-ferrous/refractory metals, to include manufacturability, weldability, compatibility, etc.

Proficiency in Engineering Change (ECN / ECR / ECO) process required for new or revised engineering designs and documentation.

Proficiency in making and reviewing 2D technical drawings and application of Geometric Dimensioning & Tolerancing (GD&T) required.

Proficiency in Solid Modelling required. Siemens NX preferred, others strongly considered.

Proficiency in PLM / ERP / MRP software, Siemens Team Center preferred.

Experience performing and reviewing Finite Element Analysis, Ansys or NX simulation preferred, with the ability to validate with hand calculations.

Previous experience working at the pace of the Semiconductor industry desired.

Working knowledge of advanced machining and fabrication techniques is mandatory (design for manufacturing/cost). Knowledge of welding practices is a major plus.

Proficiency in MS Office tools (Excel, Word, Power Point, Visio & Outlook) required.

Ability to organize work effectively and have a systematic approach to problem solving in a dynamic work environment.

Skills

Can observe and respond to people and situations and interact with others encountered in the course of work.

Can learn and apply new information or skills.

Must be able to read and interpret data, information, and documents.

Strong customer focus and commitment to customer satisfaction through prioritization, quality, efficiency and professionalism.

Ability to complete assignments with attention to detail and high degree of accuracy.

Proven ability to perform effectively in a demanding environment with changing workloads.

Result driven-demonstrate ownership and accountability.
