Job Summary
In this role, you will design and operate high-performance computing clusters, develop security architectures, and automate provisioning within a challenging HPC environment for machine learning.
Job Technologies
Your role in the team
- Design and operate their HPC clusters across four data centers, including scheduler (SLURM), parallel filesystems, networks and accelerators, ensuring high availability and throughput for research workloads.
- Conceive and establish the security architecture of the Machine Learning Science Cloud and harden the HPC environment.
- Evolve the automated provisioning and configuration of heterogeneous compute, storage, and network nodes (e.g., image-based provisioning, node lifecycle).
- Run patch and vulnerability management - risk assessment across heterogeneous systems.
- Build and operate logging, monitoring and intrusion detection, and integrate HPC telemetry into both operational dashboards and incident-response workflows.
- Lead incident response for the clusters: detection, containment, forensic support and post-incident review.
- Automate operations and security policy as code (Ansible/IaC).
- Advise researchers on efficient, secure cluster usage (job scheduling, data handling, access workflows) and derive requirements for our further roadmap from their scientific workloads.

Our expectations of you
Education
- Master's degree in Computer Science or a related field.
Qualifications
- In-depth IT security knowledge: system hardening, network security, applied cryptography and IAM - with the ability to derive architectural decisions from a threat model, not only to apply given baselines.
- Hands-on HPC background: Slurm, parallel file systems (Weka, Lustre, Ceph), GPU workloads and high-speed networks (InfiniBand, 400G Ethernet).
- A plus: security frameworks (ISO 27001, BSI Grundschutz), container security (Apptainer/Singularity/Docker) or offensive-security fundamentals.
- Independent, structured working style and good communication in English; German is a plus.
- A collaborative, user-facing mindset - comfortable supporting and advising researchers and translating their needs into platform design.
Experience
- Solid Linux experience in production environments (RHEL/Almalinux/Ubuntu).
- Experience with virtualization for management-plane and infrastructure services (Proxmox).
- Strong scripting and automation skills (Bash, Python, Ansible) and experience with configuration management / Infrastructure-as-Code.

What we offer
- Technically deep, architecturally open work that directly enables cutting-edge machine-learning research.
- Flexible working hours and the option to work partially from home.
- Working in an English-speaking, international team of HPC experts.
- A small, senior team with a flat hierarchy where responsibilities are divided by domain.
- Ownership of a technical domain in a production environment of real scale.
- Professional development, conference attendance and real influence on our roadmap.
