Company summary

In this role, you will:

  • Iterate and maintain the ML Platform, identifying opportunities to improve speed, reliability, and maintainability. You will define the long-term vision and roadmap for MLOps.
  • Work hand-in-hand with Data Scientists to support their efforts, ensuring they have the tooling to develop, deploy, and monitor scalable models efficiently.
  • Define and promote engineering best practices (coding standards, testing, CI/CD) within the ML domain.
  • Partner with Data Engineering and DevOps to align ML development with company-wide infrastructure and data governance standards.
  • Investigate and integrate new frameworks and tools (e.g., for LLMs or real-time inference) to keep our stack modern and effective.

  • Experience with real-time ML architectures, leveraging tools like Kafka for low-latency ingestion and inference.
  • Hands-on experience with vector databases or semantic search infrastructure (e.g., OpenSearch, Vertex AI), including indexing and retrieval tuning.
  • Familiarity with the broader ML toolkit, such as orchestration/tracking tools (Flyte, MLFlow, Feast) and standard libraries (Pandas, Scikit-learn, TensorFlow/PyTorch).
  • Professional proficiency in English and Spanish, with the ability to explain complex technical concepts to diverse stakeholders.

What Would Be A Plus πŸš€

  • Hands-on experience working with LLMs, RAG architectures, and libraries like LangChain or LlamaIndex.
  • Familiarity with Big Data technologies like Spark or Beam.
  • Experience with Data Engineering tools such as Airflow, dbt, or Datahub.
  • Experience with other cloud platforms like GCP or Azure in addition to AWS.
