About the Role

The Collection Platforms & AI team is building ML-powered products and capabilities for natural language understanding, data extraction, information retrieval, and data sourcing solutions. You will spearhead the development of production-ready AI products and pipelines in a highly engaging, global work environment that encourages thoughtful risk-taking and self-initiative. This role involves developing next-generation products and enhancing existing ones to solve high-impact business problems, contributing to breakthrough products and significant business value.

Responsibilities

  • Develop and deploy large-scale ML and GenAI-powered products and pipelines.
  • Own all stages of the data science project lifecycle, including development, deployment, monitoring, and scaling of models through the full Software Development Life Cycle into production.
  • Perform exploratory data analysis, proof-of-concepts, model benchmarking, and validation experiments for both ML and GenAI approaches.
  • Partner with business leaders, domain experts, and end-users to gather requirements and align on success metrics.
  • Follow coding standards, perform code reviews, and optimize data science workflows.
  • Evaluate, interpret, and communicate results to executive stakeholders.

Requirements

  • Strong grasp of statistics, probability, and the mathematics underpinning modern AI.
  • Proficiency in linear programming and optimization.
  • Experience with multi-dimensional optimizers (e.g., Adam, SGD, Gradient Descent).
  • Ability to adjust weights for full/partial tuning of LLMs.
  • Hands-on experience with large language models (e.g., OpenAI, Anthropic, Llama), prompt engineering, fine-tuning/customization, and embedding-based retrieval.
  • Intermediate to expert proficiency in Python (NumPy, Pandas, SpaCy, scikit-learn, PyTorch/TF 2, Hugging Face Transformers).
  • Understanding of ML & Deep Learning models, including architectures for NLP (e.g., transformers), GNNs, and multimodal systems.
  • Solid understanding of database structures and SQL.
  • Ability to perform independent research and synthesize current AI/ML research, with a track record of applying new methods in production.
  • Experience in end-to-end GenAI or advanced NLP projects (e.g., NER, table extraction, OCR integrations, GNN solutions).
  • Familiarity with orchestration and deployment tools: Airflow, Redis, Flask/Django/FastAPI, SQL, R-Shiny/Dash/Streamlit.
  • Openness to evaluate and adopt emerging technologies and programming languages.
  • Public contributions or demos on GitHub, Kaggle, StackOverflow, technical blogs, or publications.
  • 5+ years in professional work within AI space or building statistical/quantitative models in production.
  • Right to work within the USA (for US-based candidates).
  • Right to work within Canada (for Canada-based candidates).
