  • Integrate and operationalize new AI/ML models (NLP, LLMs, OCR, etc.), ensuring seamless deployment, versioning, and monitoring.
  • Enhance system observability, reliability, and fault tolerance across distributed services and background job managers.
  • Lead efforts to scale ingestion, processing, and retrieval of large document corpora, leveraging advanced storage and indexing strategies.
  • Collaborate with product and research teams to rapidly prototype and productionize new AI/ML features and document-centric workflows.
  • Identify and address architectural bottlenecks, technical debt, and opportunities for system modularization and performance improvement.
  • Mentor engineers, establish best practices, and foster a culture of technical excellence and continuous improvement.
Qualifications
