Summary Generated by Built In
Minimum Qualifications
  • Bachelor's degree in Computer Science, Data Science, Artificial Intelligence, or a related quantitative field.

  • 8–12 years of experience as a Data Scientist or equivalent role, with at least 2 years of specialized, hands-on experience in Generative AI, including leading technical development and mentoring teams.

  • Demonstrable experience across the full lifecycle of production-level GenAI projects — from ideation and prototyping through deployment, monitoring, and ongoing maintenance in live environments. Proof-of-concept work alone is insufficient.

Core Responsibilities
  • Working with financial and enterprise data, applying modern NLP and GenAI techniques to solve business problems.

  • Designing, refining, and systematizing prompt engineering strategies for large language models (LLMs), including structured prompting, chain-of-thought, and few-shot/zero-shot approaches.

  • Collaborating with business stakeholders to translate requirements into GenAI-powered solutions.

  • Developing, testing, and maintaining production-grade Python code for GenAI applications.

  • Integrating with vector databases (e.g., Pinecone, Weaviate, Milvus, pgvector, Qdrant) for retrieval-augmented generation (RAG) pipelines.

  • Building, monitoring, and optimizing MLOps/LLMOps pipelines for continuous model deployment and observability.

  • Researching and evaluating emerging GenAI technologies, frameworks, and best practices to maintain competitive advantage.

  • Troubleshooting and debugging GenAI models and agentic systems in production, including rapid identification and resolution of issues in real-world deployments.

  • Communicating complex AI/ML concepts clearly to non-technical stakeholders, translating technical jargon into actionable business terms.

  • Participating in and leading team meetings, design reviews, and architecture discussions.

Technical Skills

Programming & Foundations

  • Expert-level Python proficiency, including:

    • Core Python: data structures (lists, dictionaries, sets), algorithms, object-oriented programming, async programming, file handling, and exception handling.

    • Scientific computing: NumPy, Pandas, SciPy.

Machine Learning

  • Scikit-learn, XGBoost, LightGBM.

  • Strong understanding of advanced modeling techniques, model evaluation, hyperparameter tuning, and deployment strategies.

Deep Learning

  • PyTorch (preferred/primary), TensorFlow/Keras.

  • Familiarity with training, fine-tuning, and inference optimization for neural network architectures.

Model Serving & Optimization

vLLM, TGI (Text Generation Inference), ONNX Runtime, quantization (GPTQ, AWQ, GGUF), model distillation

Evaluation & Observability

LLM evaluation frameworks (RAGAS, DeepEval, custom evals), LLM observability tools (LangSmith, Arize Phoenix, Weights & Biases), red-teaming and safety testing

API Development

FastAPI, RESTful and streaming API design for GenAI applications, WebSocket integration

Responsible AI

MLOps / LLMOps

  • CI/CD for ML/GenAI pipelines (e.g., GitHub Actions, GitLab CI).

  • Experiment tracking and model registry (MLflow, Weights & Biases).

  • Containerization and orchestration: Docker, Kubernetes.

  • Infrastructure-as-code and deployment automation.

Cloud Platforms

  • Proficiency in at least one major cloud platform's AI/ML services:

    • AWS (Bedrock, SageMaker, Lambda)

    • Azure (Azure OpenAI Service, Azure AI Studio, Azure ML)

    • GCP (Vertex AI, Gemini API)

Soft Skills
  • Excellent communication and collaboration skills — both written and verbal — with the ability to effectively convey technical concepts to diverse audiences, including senior leadership and business partners.

  • Ability to articulate the challenges, trade-offs, and successes of deploying GenAI solutions at scale.

  • Proactive approach to continuous learning in the rapidly evolving GenAI landscape.

Preferred Qualifications
  • Master's or Ph.D. in a relevant field (Computer Science, AI/ML, NLP, or related).

  • Experience with MLOps/LLMOps and building robust, automated AI pipelines at enterprise scale.

  • Deep understanding of cloud-native architectures and their application in GenAI workloads.

  • Experience developing and deploying conversational AI and agentic AI solutions in production environments.

  • Contributions to open-source projects, research, or publications in the field of Generative AI or NLP.

  • Experience building, curating, and managing large-scale datasets for training or fine-tuning GenAI models.

  • Familiarity with graph databases (e.g., Neo4j) and knowledge graph integration with LLMs (GraphRAG).

  • Experience with multimodal AI (text, image, audio, video).

Education
  • Bachelor's degree / University degree or equivalent experience.
