Sr. Software Engineer

Takes full technical ownership, leading several technical complex designs. Contributes to development / change of sub-modules; responsible for results of sub-modules.

Works at Train level. Interfaces with other sectors in complexenvironment,may require negotiation.

Understands the contribution of other domains to the product;operateson module level and oversees the relations on function level. Takesend-to-end view, taking into account impact on other areas (e.g. research, customer, marketing).

Structural troubleshooting capabilities on functional level and manages many technical uncertainties at sub-module level and develops creative solutions to solve uncertainties.Can take responsibility for customer problems (end-customer/sectors in Operations),coming up withsolutions for specific issues.Representsthe competence inProductDevelopment Cycle.

Mastersa field and WoW inownfunction. Has visible impactindepartmentor groups in other disciplines. Based on in-depthexpertisein own module/technical discipline,findssolutions that are not obviousforothers. Looks forward and acts proactively (e.g.raising risks).

As a Technical Lead Designer, steers the work of 6-10 engineers.

Designs, develops,testsand integrates software for ASML’s machines and applications.Implementsanalytics, data,controland algorithm applications that give ASML customers the power to reachoptimalperformance during manufacturing., Research

Develop and/or deliver a plan for significant aspects of a research program with guidance from senior colleagues.

Evaluate emerging software technologies, frameworks, development tools, and engineering practices relevant to ASML products and platforms.

Design Requirements and Specifications

Plan and coordinate the identification, elicitation of product and/or project requirements; conduct analysis of those requirements for completion and alignment; document and manage requirements throughout the life of the project; and coordinate the verification of the end deliverable. Generally done at the project level.

Define and document software architecture requirements, quality attributes, interface contracts, and non-functional requirements including performance, maintainability, reliability, and extensibility.

Feasibility

Conduct feasibility studies from a technological and organizational perspective and document findings to complete cost-benefit analysis on implementing changes to business processes, products, or business unit structure.

Perform feasibility studies, contribute to the development of product roadmapsand contribute to the SPS/SDS.Identifyfeasibility questions and improvements inowndomain.

Assessfeasibilityof software architectures, frameworks, technology selections, deployment models, and implementation approaches.

Conceptualization

Design engineering solutions and the associated validation process to enable the realization of a design brief (for example, in terms of functionality, performance and cost) that conforms to organizational and/or regulatory standards.

Develop software concepts, architectural approaches, and engineering strategies that balance functionality, maintainability, scalability, performance, and cost.

Preliminary Design

Develop technicalconceptincluding material choices. Specify (sub)moduleusing team input, design architecture, make technical choices in all phases, solve technical issues, devisenew approachesto problemsencountered, and drive the development of the module.

Prepare high-level design of the (sub-)modulefulfillingthe requirements set while addressing architectural and interface choices. Document the high-level designinthe relevant SEG documents.

Additionally:

• Define software architecture and subsystem decomposition.

Additionally:

• Lead software integration activities across modules, services, UI components, and hardware interfaces.

• Manage software dependencies and package versioning strategies.

• Support build, deployment, installation, and upgrade processes.

• Resolve architecture, compatibility, and integration issues.

Product Quality / Testing

Perform verification of SDS, verify design specifications from teammembersand contribute to the testing process (TPS, a-test, (sub system) TAR, b-test).

Develop new testing approaches and strategies to meet changing requirements. Focus on a defined range of products,operationsor both.

Additionally:

• Drive software quality strategy and test automation.

• Perform root-cause analysis of complex software defects.

• Develop debugging and diagnostic approaches for complex systems.

• Support performance analysis and optimization activities.

• Lead design reviews and code reviews to improve software quality and maintainability.

Safety

Adheres to ASML’s EHS policies,proceduresand mandatory instructions;identifiesandmitigatessafety risk and safeguards the environment and well-being of oneself and others.

Instructs the team in safe working methods andidentifiesinstances of risky behaviors within the team and takesappropriate action, escalating serious issues asappropriate.

Project Management

Create high-level work breakdown, support planning, provide effort estimates and manage assigned projects, delegate tasks and ensuretimelyexecution and delivery according to quality standards, within the project management guidelines.

Additionally:

• Drive technical planning and architecture roadmaps.

• Identifytechnical risks and mitigation strategies.

• Coordinate technical dependencies across teams and disciplines.

• Guideexecution of complex software development efforts.

Communication and Documentation

Document complex design choices and specifications in all phases to ensure product documentation is up todateand relevant underlying assumptions and restrictions are documented.

Additionally:

• Document software architecture, APIs, design decisions, and technical trade-offs.

• Present technical proposals and design reviews to both technical and non-technical stakeholders.

• Ensure technical decisions and architectural rationale are traceable andmaintained.

Knowledge

Stay up to date on technical developments in one’s area of expertise and in general affecting ASML and contribute to the overall broadening and maintenance of ASML’s technology base.

Share knowledge, including coaching and mentoring of more junior colleagues.

Additionally:

• Maintain expert knowledge of C#, .NET, WPF, XAML, MVVM, software architecture, and software engineering best practices.
