Senior AI-ML Data Scientist
Job Summary
We are seeking a Senior AI/ML Data Scientist to own model and agent behavior end to end - from problem framing and algorithm selection through fine-tuning, retrieval design, agentic orchestration, evaluation, and production serving.
This is a hands-on role for someone with genuine depth in machine learning and statistics who is equally comfortable designing an experiment, reading an attention implementation, and shipping the result behind a latency budget. We are particularly interested in candidates who think carefully about agent memory - what an agent should retain, in what form, and how retention is grounded in a governed data warehouse rather than an undifferentiated vector blob.
This role partners closely with the AI Data Engineer, who owns the warehouse, pipelines, and index infrastructure. The boundary: they own the pipeline, the schema, and the guarantees; you own the algorithm, the prompt, and the evaluation.
Required Qualifications
5–10+ years in ML/AI engineering, data science, or related technical roles,



with proven experience deploying models at scale in production (LLM, CV, NLP, or multimodal).
ML depth: substantive command of machine learning algorithms and neural network theory -optimization, regularization, attention mechanisms, tokenization, embeddings, and model internals.
Statistics: rigorous grounding in inference, experimental design, and data analysis.
Frameworks: PyTorch (primary), plus TensorFlow or JAX; the Hugging Face ecosystem (Transformers, Datasets, TRL).
Python: expert-level, production-grade. Strong SQL for analysis against a dimensional warehouse.
Agentic systems: production experience with LangChain/LangGraph or equivalent, and a well considered position on agent memory architecture.
Knowledge graphs: hands-on ontology design and graph-based reasoning.
Cloud: expert-level deployment of AI workloads on AWS, Azure, or GCP, including GPU provisioning, cost optimization, containerization, and CI
