Data Scientist

Data Scientist Location: Houston Contract Type: 6-Month Ongoing Contract (potential to hire Fulltime) Overview • Design & deliver GenAI solutions: Architect and implement LLM/LVM applications (text and, where applicable, vision) including prompt strategies, guardrails, evaluation metrics, cost/latency optimization, and production rollout. • Build robust RAG systems: Stand up end‑to‑end RAG pipelines (ingestion → chunking → embedding → retrieval → synthesis), with observability, feedback loops, and AB testing for groundedness and hallucination control. • Fine‑tune foundation models: Select, adapt, and fine‑tune open and hosted models for domain‑specific tasks using efficient techniques (LoRA/QLoRA, PEFT, parameter‑efficient adapters), and manage evaluation datasets. • Develop agentic workflows: Implement multi‑step, tool‑using agents for real‑time, context‑aware operations; orchestrate planning, memory, and tool calling with safe‑execution policies. • ML/LLM engineering: Build high‑quality Python code, reusable libraries, and APIs; implement CI/CD, testing, experiment tracking, and model/version governance. • Data & platforms: Partner with data engineering to operationalize pipelines on enterprise platforms (e.g., Databricks/Snowflake) and integrate with cloud AI/ML services. Required qualifications Mathematics & foundations • Statistics, Multivariate Calculus, Linear Algebra, Optimization (you can explain choices and trade‑offs in model behavior based on these principles). Programming • Advanced Python (clean architecture, typing, packaging, testing; performance profiling and async where appropriate). Python ecosystem • Data Handling/Visualization: pandas, NumPy, Seaborn/Matplotlib, pyspark • Machine Learning: scikit‑learn, XGBoost, LightGBM • Deep Learning:TensorFlow or PyTorch • Generative AI:LangChain, LlamaIndex, Haystack, Hugging Face transformers Generative AI expertise • Large Language/Vision Models (LLM/LVM): Hands‑on with multiple providers/models (e.g., Gemini, GPT, Claude, Llama) and their APIs. • Model fine‑tuning: Proven experience fine‑tuning foundation models for domain tasks; evaluation design and data curation included. • Retrieval‑Augmented Generation (RAG): Ability to design and implement robust RAG systems for real‑time, context‑aware applications. • Prompt engineering & agentic workflows: Advanced prompt design (system/task/reflection patterns) and building multi‑step AI agents. • Vector databases/search & embeddings: Practical experience with vector indexing, similarity search, and embedding selection/management. Software craftsmanship & platforms • Version Control: Git (GitHub/GitLab/Bitbucket) • Databases:SQL and NoSQL (e.g., MongoDB, Cassandra) • Cloud: Hands‑on with one or more of AWS, Azure, GCP, specifically AI/ML & data services (e.g., AWS SageMaker, Azure Machine Learning, Google Vertex AI) • Enterprise data engineering platforms:Databricks, Snowflake • Azure AI Foundry:Hands‑on experience required Preferred qualifications • Vector stores/search: FAISS, Milvus, Weaviate, Pinecone; hybrid (BM25 + vector) retrieval; reranking. • LLMOps/observability: MLflow, LangSmith, OpenTelemetry, Prometheus, dashboards for cost/latency/quality; offline & online eval (e.g., RAGAS/DeepEval style). • Orchestration & data: Airflow/Prefect; Kafka/Event Hubs; Delta/Parquet; Unity Catalog/governance. • Containers & CI/CD: Docker, Kubernetes (AKS/EKS/GKE), GitHub Actions/Azure DevOps; infrastructure as code (Terraform). • Safety & compliance: Content moderation, jailbreak resistance, prompt‑leakage mitigation, red‑teaming, privacy/PII handling. • MLOps patterns: Canary/shadow deployments, feature flags, AB testing, blue‑green rollouts. • Domain experience: Background in complex, datarich industries (e.g., energy, manufacturing, industrial IoT) is a plus.
