• Reference Architectures: Design, build, and validate reference architectures that show how MinIO deploys in real AI and analytics environments, including configurations aligned to enterprise and partner architecture standards. Document them so a customer can reproduce the result. • Benchmarking and Performance Validation: Plan, run, and document benchmarks across AIStor and MemKV. Report results with full configuration and workload context, for example aggregate throughput in a stated cluster configuration or microsecond retrieval of cached context, so every number is defensible and repeatable. • Demos and Proofs of Concept: Build reproducible demos and proof-of-concept environments that demonstrate MinIO across the AI pipeline, from ingest and training data lakes to large-context serving and KV cache offload. Make complex capabilities easy to see and easy to rerun. • Integration Validation: Validate and document MinIO's integrations with the modern AI infrastructure stack, including inference frameworks, GPU-accelerated platforms, networking, and partner hardware. Surface what works, what the requirements are, and what the measured impact is. • Technical Content Creation: Produce technical blogs, deployment guides, solution briefs, and hands-on labs aimed at an architect and platform-engineering audience, written in a precise, peer-to-peer register with claims qualified by configuration and workload. • Partner Co-Engineering Support: Work hands-on with partner technical teams on joint validation, lab benchmarks, and co-engineered solutions, supporting the co-engineered, not co-marketed standard with real, reproducible results. • Field and SE Enablement: Build and deliver deep technical enablement for sales engineers and account teams, including technical briefings, demo assets, and deployment guidance, and provide hands-on support in complex evaluations and proofs of concept. • Customer-Facing Technical Engagement: Present architectures, benchmarks, and demos directly to technical buyers and architects, and bring field and customer feedback back into content, demos, and product input.
