  • Mentor engineers and support the team in maintaining a high engineering standard

What We Are Looking For

  • Strong experience building and operating data-intensive and high-scale systems
  • Experience working with OLAP workloads and query performance optimization
  • Must have strong experience with relational databases (such as PostgreSQL, MS SQL, MySQL etc.), experience with ClickHouse or other columnar databases is a plus
  • Ability to design systems that handle varying data structures and integrations
  • Comfortable working across the stack when needed
  • Ability to take ownership of complex problems and drive them to practical solutions
  • Clear communication skills and a collaborative approach to working with others
