  • Design high-performance systems for schema evolution, multi-engine compute optimization, data discovery, and data movement.
  • Prototype and benchmark emerging data technologies and specialized Spark extensions.
  • Automate data lineage, PII masking, fine-grained access control, and compliance-by-design across petabyte-scale environments.
  • Implement streaming support for OpenTelemetry data from AI agents and develop AI evaluation metrics and reporting.

Requirements

  • Experience using AI code-generation platforms in the software development lifecycle for code generation, reviews, unit tests, and root-cause analysis.
  • Ability to architect infrastructure supporting AI-agent development, including vector database integration.
  • Demonstrated ability to lead by influence, communicate architectural trade-offs, and drive adoption across multiple autonomous teams.
  • Bachelor’s or master’s degree in Computer Science with a distributed-systems focus is preferred, or equivalent deep industry experience.

Benefits

  • Health, dental, and vision insurance.
  • Retirement savings plan, paid time off, health savings account, flexible spending accounts, life insurance, and disability insurance.
