  • Experience building a data platform, having made mistakes and confident using what you've learned to construct an even more robust platform
  • Reasons about technical fundamentals such as networking, database behaviour and system performance when designing systems
  • Familiar with  building batch and stream processing systems for diverse data sources.
  • Driven to maintain operational excellence and reduce the dependency on humans within data operations.
