  • Stay ahead of the curve-continuously exploring new database technologies and performance strategies

What You Bring

  • 5+ years of experience managing both SQL and NoSQL databases in production environments
  • Mastery of at least one RDBMS (PostgreSQL, MySQL, MS SQL Server, or Oracle)
  • Deep expertise in at least one NoSQL technology (MongoDB, Redis, Cassandra, DynamoDB, Couchbase, or Dragonfly)
  • Strong background in data modeling, schema design, and performance optimization

  • Familiarity with ETL tools (e.g., SSIS) or data pipeline frameworks
  • Knowledge of SQL Server features like Synonyms, SQL Agent jobs, linked servers, and maintenance plans
  • Experience in Agile/Scrum environments
  • Strong troubleshooting, debugging, and analytical skills
  • Awareness of data security and compliance standards
  • Excellent communication skills-able to bridge technical depth with business clarity
  • A curious, data-driven mindset that turns insights into impact

Why You'll Love It Here
