YOUR ROLE AT SIXT

• You build ML powered systems together with Data Scientists and ML Engineers, from the first design session to the validated outcome in production, with one team working toward one goal
• You understand the business and the processes to build solutions and not only write code
• You design and build robust backend services in Golang that power the risk steering cycle and decision-making workflows

• You bring strong, production-proven experience in Golang, plus confidence in at least one more language such as Python or Java
• You have 7-10 years of experience working in sophisticated technology environments such as building cloud-native applications, solving scalability challenges, designing event-driven solutions, and good to have working experience in ML-powered products
• You have already designed or operated distributed systems and microservices architectures, with a clear understanding of the trade-offs that come with operating at scale, and experience working with cloud providers (AWS or similar)
• You have good understanding of event-driven platforms, pub-sub and messaging using brokers such as Kafka, NSQ or RabbitMQ
• You actively use AI coding assistants — such as Cursor, Claude— to accelerate your work, while confidently recognising their limitations and knowing when engineering judgment must take precedence
