Job summary

Blue Origin is seeking a hardware-leaning systems engineer to architect and own the nervous system of a large-scale orbital data center. You will make foundational hardware decisions for the high-speed interconnect fabric, from the physical layer to the software stack, ensuring resiliency in a radiation environment and owning performance for multi-tenant workloads.

You will define pod architecture, manage fabric software bring-up, qualify fabric switches for space conditions, and collaborate

Qualifications

• 8+ years of experience in HPC networking, datacenter fabric design, or GPU cluster engineering.
• Experience with large-scale accelerator clusters and high-speed GPU interconnects.
• Proficiency with fabric management tools and network topology at scale.

Responsibilities

• Architect the hierarchical GPU interconnect topology for a large-scale accelerator cluster, defining pod architecture, fabric switch placement, and inter-pod fabric selection.
• Own the configuration, bring-up, and operation of fabric management software, defining topology files and partitioning policies for multi-tenant workloads.
• Lead the hardware qualification of fabric switches and other network components for the space environment, developing novel strategies to mitigate radiation effects on switch state and routing tables.
• Take ownership of the collective communications performance across the fabric, tuning libraries (e.g., NCCL, RCCL) and defining the bandwidth/latency budgets required for high-performance model-parallel inference.
• Collaborate deeply with software teams to co-design the fabric topology with model parallelism strategies, ensuring optimal performance for large-scale AI models.
• Interface with platform software teams to manage the fabric software bring-up and integration process.
