  • Contribute to technical decision-making and architectural discussions.
  • Write clean, well-tested, and secure code, following best practices.
  • Collaborate in an agile, fast-moving environment, engaging directly with product and business stakeholders.
  • Languages: Python (Golang experience a plus)
  • Data: Relational and NoSQL databases
