Job description

Who We Are

Helsing is a defence AI company. Our mission is to protect our democracies. We aim to achieve technological leadership so that open societies can continue to make sovereign decisions and control their ethical standards. We believe it is our responsibility to be thoughtful about the development and deployment of powerful technologies like AI, and we take this responsibility seriously.

The role

Helsing operates on‑premises high‑performance computing (HPC) infrastructure that supports electromagnetics, computational fluid dynamics and multi‑physics simulation. As an HPC Systems Administrator based in Munich you will take ownership of this critical environment, ensuring that our simulation engineers remain unblocked, productive and equipped to solve complex problems. The role is based on‑site in Munich with regular travel to our Tussenhausen site.

The day‑to‑day

• Own day‑to‑day administration of compute nodes, workload schedulers, parallel storage, high‑speed interconnects and licence servers.
• Ensure the environment remains highly available and consistently performant through proactive monitoring, patching, firmware updates and incident response.
• Administer the workload scheduler (Slurm, PBS Pro or similar), managing queues, fair‑share policies, accounting and quotas to optimise resource utilisation.
• Manage the simulation software stack and user environments using tools such as Lmod, Spack or EasyBuild.
• Collaborate with hardware and software vendors to resolve support cases, process RMAs and ensure upgrade quality.
• Automate operational workflows using Bash, Python and Ansible to improve system efficiency and reduce manual intervention.
• Maintain the strict security posture required for cleared work and support ongoing compliance reviews.
• Onboard users and maintain comprehensive documentation to empower engineers to self‑serve.

You should apply if

• You have administered Linux systems within a production HPC or large shared compute environment.
• You have hands‑on experience managing workload schedulers such as Slurm, PBS Pro, LSF or similar.
• You possess production experience with parallel filesystems (Lustre, BeeGFS or GPFS) and high‑speed interconnects (InfiniBand or RoCE).
• You are capable of scripting and automating complex workflows with Bash, Python and Ansible.
• You can effectively manage commercial simulation software (CAE, CFD or EM) and licence servers, including FlexLM.

We operate in an industry where women, as well as other minority groups, are systematically under‑represented. We encourage you to apply even if you don’t meet all the listed qualifications; ability and impact cannot be summarised in a few bullet points.

Nice to have

• Experience administering Altair or Siemens simulation suites.
• A background working within classified or strictly regulated environments.
• Expertise in GPU computing, including CUDA and NVIDIA toolchains, alongside MPI stack management.
• Familiarity with HPC containers using Apptainer, Enroot or Pyxis.
• Experience with identity management systems such as Keycloak, FreeIPA, Active Directory or Kerberos.
• Competence in infrastructure‑as‑code practices using tools such as Terraform.

Join Helsing and work with world‑leading experts in their fields

• Helsing’s work is important. You’ll be directly contributing to the protection of democratic countries while balancing ethical and geopolitical concerns.
• The work is unique in a domain that has highly unusual technical requirements and constraints, where robustness, safety and ethical considerations are essential.
• We operate at the state of the art in technical innovation, including reinforcement learning, distributed systems, generative AI and deployment infrastructure – the defence industry is entering its most exciting phase.
• Success is measured by order‑of‑magnitude improvements and novel capabilities; we take bets, aim high and focus on big opportunities.
• We actively encourage healthy, proactive, and diverse debate internally about what we do and how we do it. Teams and individuals are trusted to practise responsible autonomy and critical thinking, and to focus on outcomes, not conformity. At Helsing you will have a say in how we work and a chance to shape aspects of our culture.

What we offer

• Competitive salary and VSOP options.
• Relocation support: up to €2,500 and four weeks of temporary accommodation.
• Learning allowance: €500/£450 yearly.
• Health & wellness: gym membership and mental health support (Nilo.health).
• Social: regularly scheduled company events and monthly social allowances.
• Enhanced parental leave: 22 weeks fully paid for primary caregivers and six weeks for secondary caregivers.
• Family support: five days of paid family emergency leave, 100% remote work option during pregnancy and phased return to work.

These are the core benefits across all locations; there may be additional benefits in certain locations.
