“We Process Engineers take responsibility for optimal production processes.”

Glimpse into an exciting field of work

What do Process Engineers at Infineon do?

Three profiles, one mission: Unit Process Developers, Unit Process Engineers and Process Integrators. Although each group has different focal areas in their day-to-day work, they share the common goal of optimizing production processes. And while they’re doing it, they work with some of the most modern technologies, materials and processes.


A job that’s comparable to cooking for a big crowd and solving Sudokus with friends.

Our goal is to keep processes running stably. If a problem arises during production, we are the firefighters who step in to start looking for a solution. For me, that’s when the fun starts: it’s like working on a Sudoku, but better, because you do it as a team.”

Katrin Koren Unit Process Engineer at Infineon in Villach, Austria

What are your tasks as a Process Engineer?

Production processes at Infineon are separated into blocks. As a Unit Process Engineer, I am responsible for one of these blocks, namely for epitaxy. That’s the artificial growth of crystalline layers on a substrate, usually a wafer.
One part of my job involves implementing processes for new wafers from Unit Process Developers, who come up with the parameters. I like to compare it to cooking: The Unit Process Developers create the recipe. My job is to ensure that the recipe can be made in large quantities and in consistent quality. For this, I need to consider which machines to use and how to configure them. I also have to think about how I can prepare my colleagues, the machine operators, for the process – for example through training measures.
The other part of my job is troubleshooting, because once production is up and running, complications can arise. In these cases, the Unit Process Engineer is the first person production staff calls in. For me, that’s when the fun starts: it’s like working on a Sudoku, but better, because you do it as a team. We scrutinize the control concepts; analyze the plant and wafer data; we talk to the Unit Process Developers and maintenance staff; and we run tests and arrange for additional analyses. All of this is necessary to decide which corrective measures to take and whether the irregulates justify stopping production.

What are the challenges in your job? How do you deal with them?

As you can imagine, my job involves communicating with stakeholders at many different levels – with managers, developers, maintenance staff and operators. A different style of communication is required for each group.
In a production environment, especially with factories that operate around the clock, there’s always something going on. Some topics are time critical, so it’s good to be able to set the right priorities.

What do you like – and dislike – about your job?

I love troubleshooting and finding solutions together with my colleagues. A real sense of unity arises, because these are problems no single person can solve on their own. Instead, it takes collaboration. Being successful as a group pulls people together and that’s extremely motivating. I also like the fact that diversity plays a big role in our project teams, with everyone bringing their strengths to the table.
Now and then the situation arises in which I need a certain device or machine, which is being used by someone else. That can be annoying. Or sometimes priorities come up that are not in sync with mine, and that makes me feel restricted in my work. On the upside, having to wait gives me a chance to develop patience. And regarding priorities, sometimes I have to be assertive.

What special talents do you need for your job?

Along with having a technical background, it’s important that you like to work in teams and that you can communicate with a wide variety of people. You also have to be able to organize your workday independently. Flexibility is a must, especially because we have to react spontaneously to disruptions in production and set priorities according to the situation at hand. You also have to be able to make big decisions, for example, to stop production to avoid serious consequences.

What is your typical day like?

I start my day by getting an overview of whether there are any disruptions in production. If there are, then that takes utmost priority. If not, then I can concentrate on more long-term projects, such as optimizing processes or developing training measures.

What are common development opportunities for a Process Engineer?

Normally you follow the technical ladder as a Process Engineer. As an expert, you can either develop further in the role, or go into process integration and from there perhaps even production development. In any case, the function of a Unit Process Engineer is also a good starting point to think about a career in management, because you get to know a lot of stakeholders at different levels. The job has a clear link to technology – as well as to people.

What else you need to know

In the video Katrin explains the differences between UPE, UPD and PI.


Within the Process Engineer role, there are three different but related profiles:


  • Unit Process Engineering (UPE)
  • Unit Process Development (UPD)
  • Process Integration (PI)

What is the difference between them?

UPEs and UPDs are specialists for a certain process block. While the UPD works more like a pioneer delivering scientific-like work for newly developed processes, the UPE is the “maker and shaker” who puts the process from the UPD into practice and optimizes it as time goes by.

In contrast, the Process Integrator is an expert in a technology. He or she ensures that a component functions as it should and that the entire process is stable. In the case of deviations, the Process Integrator has to establish whether the problem lies with an individual process or is the result of interactions among several process blocks.

The five “hats” within Process Engineering

Depending on your specific function within Process Engineering you work in the following roles and "wear the respective hats":

Unit Process Engineer

Unit Process Development

Process Integration


Creative thinker

Solution finder


Knowledge sharer

In the video you can hear what Katrin has to say about the most important skills in Process Engineering.



As a Process Engineer, you have an affinity for technical details and solving challenging technological problems in an international environment. You gladly take ownership for a topic – and then organize your schedule to tackle the tasks at hand. Strong communication skills and the ability to establish lasting relationships and networks help you get the job done. You can handle demanding schedules and work closely with other project teams along a project schedule. Last but not least, you love to think outside the box and develop innovative solutions for processes.

As a Unit Process Engineer (UPE ) you are a specialist for a certain process block and responsible for:

  • Monitoring and developing production processes for your area of expertise
  • Optimizing processes and plants in our high-tech production facilities
  • Determining the availability and stability of production assets
  • Establishing the causes of deviations as well as defining long-term corrective measures
  • Preparing and maintaining documentation and proof of functionality for the systems you are responsible for

As a Unit Process Development (UPD) you are a specialist for a certain process block and responsible for:

  • Developing and further optimizing production processes, like for instance GaN or SiC
  • Coming up with methods and processes to economically manufacture our products handing over qualified processes and control concepts to the production team
  • Procuring the necessary machinery and accompanying the processes up to volume production
  • Performing systematic analyses for process optimization and quality enhancement

As Process Integrator (PI) you are an expert in a certain technology and ensure that the entire process for this technology is stable. You are responsible for:

  • Collaborating with the joint development group and R&D for example on power technologies based on new materials like GaN or SiC
  • Acting as an interface and closely working with development, production, quality and the backend
  • Defining and driving measures to improve stability, yield, reliability and production costs across a global process chain
  • Performing root-cause analyses and defining sustainable corrective actions in the case of process deviations
  • Improving processes in regard to costs, risk and benefit

Process Engineer at Infineon

What makes this a dream job?

Infineon stands for innovation. You can work on the latest technologies and with new materials like GaN or SiC. Your work is mainly focused on projects in which you have direct control over the output and impact you produce. The daily work is challenging yet diverse, allowing you to tackle a lot of different problems in a short time period. That calls for a steep learning curve. Most of the problems you encounter can only be solved when different departments and sites collaborate. Therefore, with each project you expand your network and are exposed to a diverse set of ideas. Working in teams like this calls for a very collaborative working style and mutual respect.

What’s more, as a Process Engineer you can develop in just about any direction: You can gain further expertise and stay on the Technical Ladder. Or you can change to Process Development and later move on to Product Development. Depending on your strengths, you might also go into project management, or take on a management position. The role is definitely technical, though it also involves people.

You’ve heard Katrin’s story. This is what other Process Engineers at Infineon are saying:

  • “I can use the most expensive toys ever.”
  • “I have the opportunity to think out of the box and to develop new ideas. I have already applied for three patents.”
  • “I like the academic atmosphere in my team. We can try a lot of new things.”
