* Contribute to technical design discussions and architecture decisions
* Collaborate within an agile, product-focused environment
* Help improve platform reliability, observability, and performance
* Languages: Kotlin, Java
* Cloud: AWS (Lambda, ECS, S3, DynamoDB, RDS)
* Messaging: Kafka, SNS/SQS
* Methodologies: TDD/BDD, CI/CD, trunk-based development
What We’re Looking For
* Strong experience with Java and/or Kotlin in production systems
* Solid understanding of microservices and distributed systems
* Experience with cloud-native development (AWS preferred)
* Knowledge of relational and NoSQL databases
* Familiarity with event-driven architectures
* Passion for clean code, testing, and engineering excellence
* Excellent communication and a collaborative mindset
Why Join Us?
