About our technology

The semiconductor industry’s growing demand for more powerful chips with higher bandwidth and lower power finds its solution in our technology. We connect chips to high-throughput, low-delay computing networks. The key lies in harnessing the physical properties of graphene to combine electronic computing with photonic communication, allowing countless chips to interact almost as if they were one. Our graphene photonic innovation increases computing power and efficiency to a new order of magnitude.
In short, we connect chips to create powerful and energy-efficient networks, overcoming connectivity limitations in the semiconductor industry. We deliver the graphene solution.

The Role

We are looking for a Senior IT System Architect (f/m/d) who will design, optimize, and ensure the stability, security, and efficiency of our IT landscape. As a fast-growing startup, we are still shaping our IT infrastructure, meaning that you will have the opportunity to architect and drive its evolution.

While we currently rely on specific technologies, such as Proxmox, Fortigate, HP Aruba, Microsoft 365, and device management tools like Jamf Pro and Intune, we are not looking for a specialist in these exact systems. Instead, we value broad architectural expertise, a strong problem-solving mindset, and the ability to design scalable and adaptable IT solutions that align with business needs.

Since our IT environment is still evolving, you will play a key role in defining best practices, establishing architectural guidelines, and ensuring long-term scalability. If you enjoy working in a flexible, hands-on setting where you can make a real impact, this role is for you.

To join our team, you should be excited to

• Architect and design scalable and secure IT infrastructure solutions, ensuring long-term stability and efficiency.
• Define and optimize enterprise IT architecture, covering virtualization (e.g., Proxmox), firewalls (e.g., Fortigate), and network components (e.g., HP Aruba switches).
• Develop and implement device management strategies using Jamf Pro (macOS) and Microsoft Intune (Windows & mobile devices).
• Ensure network performance optimization, security best practices, and high availability across LAN, WLAN, and WAN environments.
• Support scalability and modernization of virtualization platforms and hybrid cloud integrations.
• Establish IT security frameworks, including network segmentation, endpoint protection, and compliance standards.
• Provide architectural guidance for IT operations in critical environments such as cleanrooms and semiconductor facilities.
• Automate and streamline IT operations, leveraging scripting and automation tools to enhance efficiency.
• Develop and maintain IT governance policies and disaster recovery strategies to ensure business continuity.
