Role	Required	Description
LLM Engineer		Knows vLLM basics: what is PagedAttention, continuous batching, inference serving. Launches vLLM server for pre-trained model inference with basic configuration under mentor guidance.

Role	Required	Description
LLM Engineer		Independently configures vLLM for production: tensor parallelism, quantization (AWQ/GPTQ), GPU memory management. Optimizes throughput by tuning batch size and scheduling parameters.

Role	Required	Description
LLM Engineer		Designs production vLLM infrastructure: multi-model serving, speculative decoding, custom sampling strategies. Optimizes latency and throughput through advanced configuration and hardware-specific tuning.

Role	Required	Description
LLM Engineer		Defines vLLM deployment standards for the LLM team. Establishes guidelines for configuration, monitoring, capacity planning. Coordinates upgrades and migration between vLLM versions.

Role	Required	Description
LLM Engineer		Shapes enterprise vLLM inference strategy. Defines approaches to multi-cluster inference, hardware planning (A100/H100/H200), and cost optimization. Ensures SLA for critical inference workloads.
