· Participate in code reviews, architecture discussions, and CI/CD processes

· Write unit, integration, and data tests to support reliable delivery

· Contribute to system modernization efforts, replacing legacy components with scalable cloud-native services

· Deploy and manage services in containerized environments using Kubernetes and Helm

Benefits

· 5+ years of experience in software engineering, with a mix of backend and frontend development

· Experience with Snowflake and dbt

· Exposure to cloud platforms (AWS, Azure, or GCP) and infrastructure-as-code

· Knowledge of messaging or event streaming tools (e.g., Kafka, RabbitMQ)

· Experience leveraging AI-assisted development tools or agentic AI workflows to improve productivity, code quality, and problem-solving
