Global Purchasing & Supply Chain Management

Ongoing innovation is the most important driving force at AIXTRON. What makes our products so exciting is that we explore the limits of what is technically possible. Short development cycles with a well-stocked product pipeline secure our market leadership. Our suppliers support us during product development and are vital to ensuring a smooth supply of materials. This is why they are part of AIXTRON’s value system. Our team of specialists in Global Purchasing buy products and services on global procurement markets with foresight and care. We employ the entire range of tools available to us, encompassing everything from market analysis through to careful examination of our suppliers’ terms and conditions of payment. Our Supply Chain Management team ensures the availability of materials and acts as a link between the commissioning departments – so Sales, After Sales, Marketing and Development – and Global Purchasing and Production. Join our team as a category manager, project buyer, analyst, planner or management expert and make AIXTRON your next career move.

We act with foresight

As a producer of high-tech systems, AIXTRON is required to fulfil the very highest market requirements and customer expectations. These demands on our systems, services and processes not only apply to technical matters but also present the challenge of maintaining a high-quality supply chain. Process design and documentation play a key role in this. Our goal is to define, implement and constantly monitor the optimum procurement and provisioning strategies for our complex products. This ensures that we can supply our company with the goods and services it needs. The continuous optimisation of procurement terms and conditions allows us to constantly leverage savings potential and safeguard the competitiveness of AIXTRON.

Forecasting allows us to identify future demand in advance. Forecasting processes allow Global Purchasing and Supply Chain Management to supply Production, Development and our customers with materials and replacement parts, all while keeping the capital commitment of our global inventories at a suitable level. These conditions ensure that the job is rich in variety and challenging tasks that we tackle with passion and dedication. What’s more, Global Purchasing is internationally positioned and works closely with our subsidiary in Cambridge.

Success through teamwork

Text (ca. 450 Zeichen inkl. Autor gemäß Bildhöhe): I started working as an e-planning technician 25 years ago. I joined Purchasing in 2001, underwent ongoing training and development and, since 2021, have been working as a team lead for electronic materials. Teamwork is what always excites me about working here at AIXTRON. We’re a big team that successfully develops and manufactures systems and sells them all over the world. Each and every member of the team is crucial to this success.

Exciting challenges every day

Getting things done together. Being right at the forefront of putting new ideas into practice. Being part of an amazing team. For me, every day at AIXTRON is an exciting challenge that we can successfully confront together. As a project buyer, I’ve been encouraged to bring my ideas to the company right from day one and have always been empowered to pursue my goals.

Purchasing for an innovation leader

Purchasing for an innovation leader means keeping constant track of the latest technologies and manufacturing procedures. We are constantly exploring the limits of what is technically possible. This is what makes AIXTRON’s Global Purchasing department so exciting. In a future-proof, high-tech industry, AIXTRON was always going to be my first choice.

What motivates you here at AIXTRON?

As a senior expert in procurement strategy and analytics, I help to optimise the department’s strategic, process-related and analytical alignment. In addition to the diverse range of tasks, I enjoy enormous decision-making freedom and can always bring my own ideas to the table. Reducing my working hours allows me to strike the perfect balance between work and family.
