• Good understanding of distributed systems, Kafka, and handling reliable financial transactions.
• Experience managing live systems, including monitoring, troubleshooting, and deploying updates.
• Awareness of security best practices, including access management, data protection, and secure coding.
• At least one year of hands-on experience using AI tools, with examples of building AI agents or automations that have reduced manual work and improved efficiency.
