The listing
We build and operate the compute infrastructure our researchers run on, supporting large-scale processing of historical market data and model training on our own hardware across multiple data centers. Our environment includes bare-metal Linux, virtualization, storage, and GPU clusters, where performance, reliability, and predictable system behavior are critical.
Our Infrastructure team covers monitoring and automation, distributed storage, hardware and OS provisioning, GPU clusters and workload scheduling, high-speed networking, L2/L3 Linux support, and security engineering. Engineers here own their tasks end to end, so there's room to go deeper in your area and pick up the parts you haven't touched yet.
We’re looking for a Linux Infrastructure Engineer who can work hands-on with server and cluster environments, from deployment and configuration to performance tuning, troubleshooting, and ongoing improvement
What You’ll Be Doing:
- Deploying, configuring, and maintaining Linux-based bare-metal servers across our data centers
- Building and operating clustered environments, including virtualization, storage, GPU compute, and database clusters
- Troubleshooting complex Linux, hardware, networking, and cluster-level issues
- Performance tuning for throughput, latency, stability, and resource utilization
- Monitoring infrastructure health and performance, identifying bottlenecks, and preventing recurring issues
- Supporting the full server lifecycle: provisioning, setup, upgrades, and maintenance
- Improving reliability and predictability during failures, maintenance, and scaling
- Automating provisioning, configuration, and operational tasks, primarily using Ansible and scripting
What We Look For In You:
- Strong hands-on Linux administration and troubleshooting experience
- Production experience with on-premise, bare-metal infrastructure
- Good understanding of Linux performance and bottleneck analysis
- Experience with:
- infrastructure monitoring and troubleshooting production issues,
- server provisioning, configuration, and lifecycle management,
- infrastructure automation, ideally using Ansible
Nice-to-have:
- Experience Experience with hardware bring-up and lifecycle management: BMC/IPMI, firmware, BIOS tuning, and automated OS provisioning (PXE/netboot)
- Experience with virtualization clusters, including live migration and HA
- Experience with distributed storage clusters, including replication, rebalancing, and recovery from disk and node failures
Why Should You Join Our Team?
- Great challenges with many opportunities to prove yourself
- A welcoming group of highly qualified international professionals
- Cutting-edge hardware and technology
