What We Are Looking For:

• 3+ years of experience delivering end-to-end NLP and LLM solutions.
• Strong command of bidirectional Transformer models such as BERT, ALBERT, and RoBERTa.
• Experience with fine-tuning, LoRA, quantization, distillation, and model evaluation.
• Experience with LLMs in production, including prompting, structured outputs (JSON schema), RAG (FAISS/Milvus), batch and async inference, and cost/latency monitoring.
• Strong experience in AWS, including SageMaker, ECS, S3, Glue, Lambda, Step Functions, and CDK for IaC, or similar services in Azure/GCP.
• Experience with PyTorch or TensorFlow, PySpark, scikit-learn, pandas, and NumPy.
• Experience building production-grade APIs with FastAPI or Flask for real-time inference.
• Solid experience in MLOps, including MLflow/W&B, CI/CD, model registry, drift monitoring, and canary/shadow deployments.
• Advanced knowledge of SQL databases, data lakes, and search engines such as OpenSearch or Elasticsearch.
• Advanced proficiency in English.

How We Support You:

• 100% remote - work from anywhere.
• Excellent compensation in USD or your local currency if preferred.
• Flexible hours - make your schedule.
