• Develop RAG pipelines with embeddings, vector stores (pgvector, Pinecone, Weaviate) and rerankers
• Cut inference cost with quantization, batching and caching
• Write clean, tested Python and review teammates' code
• Deploy models behind low-latency APIs with FastAPI, Triton, TorchServe or vLLM

Qualifications

• 10+ years of software engineering experience, with at least two spent on ML systems in production
• Comfortable with SQL and large-scale data processing in Spark or Ray
• Understanding of core ML concepts: overfitting, evaluation metrics, bias in training data
• Experience deploying models as services and monitoring them

Preferred

• Computer vision background (OpenCV, detection, segmentation)
• Published papers or open source ML contributions
• Guardrails, red teaming or safety evaluation for LLM features
• Recommendation or ranking systems at scale
