Résumé du poste

Lumafield seeks an Infrastructure Engineer to own and operate the on-prem Voyager CT data platform within customer walls. You will design, prototype, and harden high-performance stand-alone systems, balancing compute, storage, and networking for edge deployments.

You will lead bare-metal provisioning, security hardening for air-gapped environments, and maintain firmware, networking, and Kubernetes services on fixed capacity platforms.

Qualifications

• 3+ years building and operating physical server infrastructure.
• Experience with Linux server administration, network troubleshooting, docker deployments, productionizing systems.
• Experience in configuring Linux systems, applying best practices, and automating workflows with Ansible and scripting.
• Hands-on with bare-metal provisioning: PXE/netboot, cloud-init, golden images, and firmware or BIOS configuration through Redfish or IPMI.
• Real networking depth: VLANs and subnetting, DHCP and DNS, firewall policy, link aggregation.
• Working knowledge of Kubernetes on fixed capacity

Responsabilités

• Design standalone, high-performant On-Prem systems: compute nodes, storage topology, networking, power, and rack layout.
• Prototype and profile: benchmark throughput, network bandwidth, and memory contention.
• Own the engineering deliverables Manufacturing needs to build these without you: hardware and software BOMs, wiring and rack diagrams, network and IP plans, and provisioning and test work instructions.
• Harden the appliance for the customer's site: encryption, network segmentation and firewall policies, and update mechanisms that survive an air gap.
• Run Kubernetes on fixed capacity - node pools, worker placement, and the storage and database services beneath them.
• Partner with Manufacturing, Supply Chain, and Field Services to move from prototypes to a product we can build repeatedly, and stay on the hook for what comes back from the field.
• Feed on-prem constraints back into our technology roadmap, aligning the next generation of the pipeline with the hardware it will live on.
