• Implement background jobs and event consumers using Kafka, SQS or RabbitMQ.
• Secure endpoints with OAuth 2.0, JWT validation and proper input checks.
• Model data and write migrations for PostgreSQL, MySQL or DynamoDB.

What you bring

• 3-5 years of backend development experience in a production environment.
• Strong SQL and relational data modelling skills.
• Hands-on experience with AWS, GCP or Azure services.
• Familiarity with Docker and CI/CD pipelines.
• Working knowledge of message queues or streaming platforms.
