Role	Required	Description
LLM Engineer		Knows RLHF basics: reward model, PPO, preference learning. Understands why RLHF is used for LLM alignment and studies basic concepts under mentor guidance.

Role	Required	Description
LLM Engineer		Independently implements RLHF pipelines: preference data collection, reward model training, PPO training with trl library. Applies DPO as an alternative to PPO for more stable training.

Role	Required	Description
LLM Engineer		Designs advanced RLHF systems: iterative RLHF, Constitutional AI, reward model ensembles. Optimizes RLHF pipelines for training stability and alignment quality.

Role	Required	Description
LLM Engineer		Defines RLHF strategy for the LLM team. Establishes best practices for data collection, reward modeling, training stability. Coordinates RLHF experiments and production integration.

Role	Required	Description
LLM Engineer		Shapes enterprise RLHF strategy. Defines approaches to scaled preference data collection, advanced alignment techniques, and research directions. Mentors leads on RLHF and alignment research.
