As a Senior Backend Engineer in our B2B Sales team, you will build and scale the platform that powers enterprise sales and revenue management for clients worldwide. You will work on real challenges that matter, in a high-ownership environment built on cloud-native microservices where great engineering directly drives business growth. If this sounds like your next move, apply now and become part of something bigger.
YOUR ROLE AT SIXT
- You will build reliable, consumer-facing backend software in Java that powers the B2B Sales platform, directly supporting sales performance and revenue management at scale
- You will design and own end-to-end distributed systems on the cloud, balancing scalability, resilience, and engineering craft across our microservices ecosystem
- You will develop shared libraries and internal tooling that raise the delivery velocity of the entire B2B Sales engineering team
- You will work on event-driven architectures, keeping yourself ahead of emerging technologies to build solutions that grow with SIXT's enterprise ambitions
- You will champion AI-assisted development as a core part of your engineering culture — integrating tools such as Cursor, and Claude into daily workflows while guiding the team on where human expertise must lead
YOUR SKILLS MATTER
- Education: You hold a B.Tech, B.E., or Master's Degree in Computer Science or a closely related discipline

- Tech Stack: You have strong, production-proven experience with Java and Spring Boot (must-have) and are confident navigating a modern microservices landscape end to end
- Architecture: You have designed or operated distributed systems and microservices architectures, with a clear understanding of the trade-offs that come with operating at scale
- Messaging & Streaming: You have a solid grasp of event-driven patterns, pub-sub models, and message brokers such as Apache Kafka
- AI Tooling: 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
