Software Architect for Semiconductor Equipment Control

As a Software Engineer for Semiconductor Equipment Control Software at Sioux, you are responsible for the entire software engineering process covering software requirements engineering, software design, software construction (implementation), software testing, program analysis, and software maintenance. On this career trajectory you can advance into the role of a lead software or system architect in line with the impact and independence of your individual contributions to the team that you are guiding.

The role will involve developing equipment control software to support customers in the mentioned domains.

The role involves engineering equipment control software for semiconductor equipment and bringing novel AI algorithms into the field.

Your responsibilities include:

· Collaborating with customers / stakeholders to define product architecture

· Analyze customer needs in software requirement engineering

· Analyzing, designing, implementing, and testing the control software.

· Conducting peer reviews to ensure product quality.

· Leading the development team and ensuring team performance

· Working as an integral part of a Sscrum team and handling user stories across the full stack.

· Developing functionality using Agile practices, emphasizing speed and quality.

The Job Scope

Technically, the job scope comprises developing testable, high-quality equipment control software covering the full semiconductor equipment control software stack from low-level FPGA, i.e. VHDL, and/or PLC programming, to high-level human-machine interface (HMI / UI) development in technologies like WPF or MAUI. You will collaborate with our algorithm team on integrating their AI algorithms into the equipment requiring an understanding of the machine learning (ML) pipeline, neural networks, deep learning, large language models (LLMs), as well as basic understanding of other engineering disciplines like mechanical, mechatronics, optical, or electrical engineering.

The job scope comprises leading the Scrum team technically through sprint planning, design review, pull request review, design / code refactoring activities, i.e. covering the entire software engineering lifecycle.

In particular the job scope covers the following layers of the semiconductor equipment control software development:

• Implementing the equipment’s hardware abstraction layer to enable a programmable interface for components like wafer aligners, robot transfer arms, wafer stages, load ports for accessing wafer carriers, I/Os for e.g. the equipment’s traffic light tower.

• Implementing the equipment’s devices and domain layer to model SEMI-compliant state machines for the equipment’s sub-modules including scheduling (sequencing) to enable functionality like loading wafers from the carrier via the aligner, where the substrate ID (OCR ID) is read, into the process chamber.

• Developing the equipment’s application layer to support functionality like recipe management (process program management), system calibration including positional error measurement and compensation.

• Implementing the equipment’s human-machine interface (UI) compliant with the SEMI E95 standard to meet the requirements of modern diffusion as well as assembly and test manufacturing sites.

• Implement the infrastructure layer with functionality to read/write substrate maps (wafer maps as well as strip maps), test data files (like KLARF), checksum generation and verification according to SEMI M12.
