• Ability to understand an existing codebase and become productive quickly
• A disciplined approach to testing, code review, debugging, and source control
• Clear written and verbal communication

• Experience building multi-tenant SaaS applications
• Experience with Kafka, event-driven systems, Redis, or OpenSearch
