Job summary

Jobtailor is seeking a senior SRE/architecture lead to own the end-to-end NeoCloud SRE platform architecture in a multi-region environment. You will draft and maintain the platform architecture document, review framework-level changes, and set design invariants to ensure robust operation across teams.

Ideal candidates combine hands-on GPU compute experience with strong DDD instincts and proven ability to coordinate security, cloud-service teams, and tenants.

Qualifications

• 10+ years in production SRE/platform engineering/infra-architecture, incl. ≥3 years at architect level.
• Hands-on with GPU/AI compute infra, including NVIDIA GPU ops and related fabrics.
• Experience with multi-region observability, metrics/logs/traces, and SLI/SLO discipline.
• Cluster platforms experience with Kubernetes and at least one batch scheduling tool.

Responsibilities

• Own end-to-end architecture of the NeoCloud SRE platform.
• Write and maintain the platform architecture document.
• Review every framework-level change and set design invariants.
• Run the plugin framework and coordinate tier placement.
• Collaborate with cloud-service teams, tenants, and security.
• Pre-flight roadmap items and defend the design under review.

Job description

Responsibilities

• Own the end-to-end architecture of the NeoCloud SRE platform.
• Write and maintain the platform architecture document.
• Review every framework-level change.
• Set design invariants.
• Run the plugin framework.
• Decide tier placement.
• Coordinate with cloud-service teams and tenants.
• Coordinate with Security.
• Pre-flight roadmap items.
• Defend the design under review.

Requirements

• 10+ years of production SRE / platform-engineering / infra-architecture, including ≥ 3 years at architect level.
• Hands-on with GPU / AI-compute infrastructure — NVIDIA GPU ops (DCGM, MIG, vGPU, NVLink/NVSwitch, XID semantics, NCCL), InfiniBand or RoCE fabrics (subnet manager, fabric partitioning, optical health), HPC storage (Lustre, NetApp/Pure/DDN/VAST, NVMe-oF).
• Multi-region observability at scale — metrics / logs / traces / profiles / analytics-lake substrate; recording rules, MWMBR burn-rate alerting, SLI/SLO discipline.
• Cluster platforms — first-hand experience with Kubernetes (control plane + GPU Operator + topology-aware scheduling) AND at least one of Slurm / Volcano / Kueue / Ray / KubeRay.
• Data-center operations — ZTP, BMC/IPMI/Redfish, BIOS/firmware lifecycle, RMA, multi-vendor OEM management (self-built + leased DC mix).
• Strong DDD instincts — bounded contexts, public contracts, no shared databases, one-context-one-repo discipline.
• Plugin framework design — you have built (or substantively contributed to) a real extension framework with a uniform manifest + lifecycle.
• Writing fluency — you can author and maintain a multi-thousand-line architecture document under review without it drifting; you can also write a one-pager an executive will read.
• Cross-team operating tempo — design reviews, runbook authorship, on-call shadowing, post-mortem facilitation Hyperscale or NeoCloud experience.
• BS/MS in Computer Science or similar.
