## Description

Introduction to the job We are looking for a software engineer who has a passion for designing and coding software for a distributed control system. They should also be excited about the opportunity to integrate AI into existing systems and processes to improve efficiency and efficacy. Join ASML and you will be joining a team that operates in a fast-paced, uniquely innovative and challenging environment to create world class EUV technology within ASML. You will work with software and control system engineers in an Agile team as you develop software in response to the system requirements and design documents. You will get to participate in designing for excellence, keeping in mind all the –cities and –abilities like reusability, modularity, simplicity, maintainability, In addition you will determine the best test methodologies, and contribute in all aspects of the software development, build, test and release cycle. In this role, you will partner with software architects and functional engineers to design, test, and deploy innovative software solutions for our global customer base. This is a unique opportunity to contribute to cutting-edge technology in a fast-paced, multidisciplinary environment. Control system software overview: The control loops involve data exchange at speeds up to 100 kHz while data collection for diagnostics purposes is done at up to 1Khz rate. There is interaction between control loops running on quad core boards and platform software that runs on IBM bladecenter. Data is stored on board in postgres databases and is shipped via the fab network to data servers in San Diego. Our graphical user interface developed using Qt serves a complex set of users - operators, engineers, scientists and customers. And we don't forget safety; the control system has a Siemens PLC to ensure both human safety is ensured, and machine damage is prevented. CPDs are user-facing applications that allow operators to perform diagnostics and maintenance. Drivers provide programmatic interfaces for changing physical components of the machine. Role and responsibilities As a Software Engineer your responsibility includes: Working in a team of highly skilled software and cross functional engineers responsible for delivering software solutions that enables the ever-increasing miniaturization of semiconductor technology. Work in hard and soft real time domain with complex hardware interfaces and various communication protocols and platforms (Xilinx SOC, PLC, TCP/IP, Ethercat, etc.). Using Agile methodology to develop the software using C++ and Python on Linux OS environments. Creating designs and Implement code that are modular, scalable, robust and meet customer requirements. Perform unit testing and on-target testing to ensure the software meets the high-quality standards our customers expect. Evaluation of technical issues, risks, and dependencies for projects. Interfacing with stakeholders to gather a complete understanding of their requirements. Verify stability, interoperability, portability, security, or scalability of system architecture. You will also participate in continuous process improvement activities aimed at ensuring the processes and tools used throughout the software development lifecycle are increasing the team’s ability to develop high quality software in the most efficient manner. Other duties as assigned. Education and experience Bachelor's degree in Computer Science, Computer Engineering or other related Eng/Science fields. At least 5 years in technical development role with strong software engineering skills. Delivered 3+ mid to large scale software projects with demonstrable quality. Proven ability to guide a team in coding efforts for a distributed control system. The coding will require programming in different languages (C++, Python) on different OS environments (VxWorks, Linux). Experience in leadership or designing software for a complex multi-processor distributed control system is a plus. Hands on
