Responsibilities:

Data to training sets: turn unstructured and structured traveler and catalog data into narrative text documents and synthetic data, at a scale of tens of millions of documents.
Feature and context engineering: decide what information goes into each document and how to express it, such as market-relative price, tier and trip context.
Large-scale distributed training on Amazon SageMaker AI, including HyperPod.
Fine-tuning: LoRA/QLoRA adapters, supervised training, and reinforcement learning for ranking and reasoning.
Deep learning modeling: model architecture, ranking heads, co-training and multi-task setups.
Inference and deployment: low-latency, cost-efficient serving, including quantization, distillation and profiling.
Evaluation and error analysis: build evaluation sets, run ablations and catch data leakage. Write up findings clearly for the customer and the AWS science team.
Data privacy: handle customer data safely, including removing per

Amazon SageMaker AI: processing, training, distributed training (HyperPod), deployment.

LLM fine-tuning (LoRA/QLoRA) and reinforcement learning (e.g. GRPO/PPO-style methods).

Strong deep learning fundamentals in PyTorch: architectures, training dynamics, co-training.

Large-scale batch LLM inference and production inference (vLLM, Amazon Bedrock batch).

Data privacy and security on AWS: personal-data removal, IAM, KMS, Lake Formation.

Clear written communication with customer and science stakeholders.

Preferred skills

AWS Trainium / Inferentia (Neuron SDK).

Recommender systems: ranking metrics (NDCG, MRR), sequential and generative recommenders.

Embedding quantization or semantic IDs.
