Infrastructure Support Engineer

About Lyceum

Lyceum is building a user-centric GPU cloud from the ground up. Our mission is to make high-performance computing seamless, accessible, and tailored to the needs of modern AI and ML workloads. We're not just deploying infrastructure – we're designing and building our own large-scale GPU cluster from scratch, powered by 100% renewable energy.

The Role

As Infrastructure Support Engineer, you are the first technical point of contact for our customers when something goes wrong with their VMs or GPUs. You dig into logs, find the root cause, fix what you can, and keep customers in the loop until the issue is solved.

This is a hands-on execution role – perfect if you love solving real infrastructure problems and want to grow with a fast-moving AI cloud.

What You'll Do

• Receive and respond to customer issues with VM and GPU infrastructure, mainly via chat
• Investigate problems such as a machine going down by checking logs and identifying the cause
• Fix issues directly where you can
• Coordinate with our data centre partners and internal teams when needed
• Keep customers updated until their issue is resolved
• Provide technical coverage during European business hours

What We're Looking For

• Experience in technical support, SRE or sysadmin roles
• Strong Linux skills: logs, SSH, basic networking
• Understanding of VMs and basic GPU setup (drivers, CUDA)
• Structured troubleshooting: you find root causes, not just symptoms
• High sense of urgency, don't keep customers waiting
• Clear written English for customer chat, German is a plus
• Reliable availability during European business hours
• You prefer hands-on execution over managing others

Bonus Points

• Experience at a networking, hosting or cloud company
• Hands-on exposure to GPU or HPC environments
• Previous experience in fast-moving startup environments, ability to adjust quickly and take ownership

Why Join Us

• Real infrastructure: Work hands-on with large-scale GPU clusters that power modern AI workloads
• Real ownership: Own customer issues end-to-end from day one
• Founder access: Work directly with the founding team
• Steep learning curve: Grow fast in GPU, cloud and AI infrastructure
• Early-stage journey: Help shape how Lyceum supports its customers from the start
• Mission-driven team: Build sustainable, 100% renewable compute for the AI era, backed by top-tier investors
