• Are passionate about full-stack development, particularly in the context of experimentation platforms.
• Have experience with A/B testing frameworks and experimentation workflows.
• Have designed and built reliable, scalable systems and enjoy working on backend services and APIs.
• Write clean, testable code in PHP, Python, or Java.

• Have experience with cloud platforms like Google Cloud Platform (GCP), AWS, or Azure.
• Are comfortable with Git and understand branching strategies.
• Work effectively in Linux-based environments and use the command line.
• Are familiar with CI/CD tools, Docker, and Kubernetes.
• Have experience with monitoring and alerting tools such as Prometheus and Grafana.
• Are familiar with front-end technologies, especially React.
• Have experience with data warehousing (e.g., BigQuery), ETL processes, and big data frameworks like Kafka, Spark, and orchestration tools like Airflow.
