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/CD.

Experience with experiment tracking and model lifecycle tooling (MLflow, Weights & Biases).

Preferred Qualifications

Direct experience implementing CoALA or a comparable cognitive architecture (SOAR, ACT R, or a documented in-house framework) in a shipped agent system.

GPU acceleration internals: CUDA, TensorRT, cuBLAS.

Production experience with vLLM, NVIDIA Triton, Ray Serve/Ray Train, DeepSpeed, or FSDP.

Experience with AI security, governance, and compliance frameworks.

Track record of contributing to open-source AI frameworks, or published research.

Ability to lead technical discovery phases and client-facing AI workshops.

Familiarity with lakehouse table formats (Iceberg, Delta Lake) sufficient to collaborate credibly with data engineering.
