• Proven track record architecting and sizing enterprise compute clusters and hardware accelerator platforms.
• Solid architectural grasp of high-speed, low-latency fabric networking such as InfiniBand or high-performance RoCE/lossless Ethernet fabrics.
• Demonstrated experience partnering with enterprise account executives through the complete pre-sales lifecycle, including discovery, technical qualification, and solution design.
• Strong executive presentation, consultative whiteboarding, and technical communication skills.

Desired Skills & Experience

• Experience supporting large-scale enterprise deployments, benchmark validations, and formal technical proposals/RFPs.
• Familiarity with cluster management tools, distributed computing platforms, or high-throughput enterprise storage architectures.
• Background working with enterprise hardware vendors, systems integrators, or specialized cloud infrastructure providers.
• Bachelor's degree in Computer Science, Electrical Engineering, Mechanical Engineering, or related technical field, or equivalent practical experience.
