Your role in the team
- In order for our research to be successful, we need IT that is as ambitious as our technology: secure, reliable, and ready to grow with our company.
- We are rebuilding our IT infrastructure to a large extent. Together with our IT Lead, you will shape our infrastructure, processes, and security standards—with a high degree of responsibility and real creative freedom.
- Therefore, we are not looking for someone who is limited to a narrow specialty, but rather a hands-on IT all-rounder with broad technical knowledge.
- You enjoy solving problems holistically and like working in a team.
- You operate and develop our hybrid IT landscape further - from cloud services and highly secure on-premise environments to servers, storage, networks, and end devices.
- You design, operate, and secure our highly secure on-premise platform, particularly virtualization and storage clusters based on open-source technologies such as Proxmox VE and Ceph.
- You establish pragmatic, well-documented IT processes—including asset and license management, patch and change management, backup and recovery, as well as onboarding and offboarding.
- You support the development of our information security management system, aligned with standards such as ISO 27001 and TISAX, and implement technical security measures.
- This includes, among other things, Identity & Access Management, hardening, network segmentation, logging, and vulnerability management.
- Together with our external partners, you are responsible for the Microsoft stack.
- You manage service providers around Microsoft 365, Entra ID, and Intune, ensure quality, and serve as the internal contact person.
- You operate and integrate typical business applications such as ERP, CRM, and DMS systems as well as collaboration tools and incorporate them into our identity and security landscape.
- You connect IT, research, and production, supporting laboratories and production-related systems together with our scientists and engineers — from measurement instruments and research software to IT/OT.
- You automate recurring tasks with scripts and Infrastructure-as-Code and assist in the evaluation and operation of AI tools as well as local AI infrastructure.
- You support and train our employees in a practical manner - especially when working in secure environments.
Our expectations of you
Education
- A degree in computer science, business informatics, or a related field, or a completed apprenticeship, for example as an IT specialist for system integration — as well as several years of practical experience in system administration.
Qualifications
- Extensive knowledge in the administration of Linux and Windows servers, virtualization, storage, networking, and end devices.
- You are familiar with VLANs, firewalls, VPN, DNS/DHCP, WLAN, and Endpoint Management.
- Good knowledge of the Microsoft ecosystem, especially Microsoft 365, Entra ID or Active Directory, Intune, and Exchange Online.
- A strong security awareness and understanding of Least Privilege, Hardening, Backup Strategies, and Secure-by-Design.
- Scripting skills in PowerShell, Bash, and/or Python.
- An independent and structured way of working.
- You enjoy documenting your solutions, building pragmatic processes, and communicating clearly with research, management, and external partners.
- Excellent German and English language skills, both written and spoken.
- A valid work permit for the European Union and a willingness to undergo a security clearance process.
Experience
- Experience with Proxmox VE and/or Ceph – or solid knowledge in virtualization, for example with VMware or Hyper-V, and the motivation to learn new technologies.
- Experience with common business applications and ideally initial exposure to research or production environments, such as laboratory IT, measurement systems, MES, LIMS, or ELN.
- Genuine interest in AI and practical experience with AI tools - ideally also with the local deployment of models.
What we offer
- 30 days of vacation.
- Location-dependent benefits: In Berlin, we subsidize the Deutschlandticket, and in Osnabrück, you receive a subsidy for the gym.
- Flexible working hours.
- The opportunity to actively shape an innovative and growing deep-tech startup and influence the future.
- The opportunity to contribute to strengthening the semiconductor industry in Europe and to developing solutions for the challenges of climate change.
- An environment with a technology and a product that can change the world.
- A diverse and ambitious team with flat hierarchies that combines science and entrepreneurship.
- An open culture that values exchange and collaboration.
- An exceptional learning environment through close collaboration with our scientists and insights into innovative technologies.
