Software Development Engineer III (Java Backend)

Job Description At SIXT, we are engineering the future of mobility — one system at a time. As a Senior Backend Engineer in our BranchOps team, you will engineer the systems that power the full vehicle turnaround lifecycle and branch-level fleet orchestration, with deep integration into our IoT-connected fleet infrastructure. This is a role where backend engineering meets real-world operations at scale, in a team that builds with purpose and moves with pace. If this sounds like your next move, apply now and become part of something bigger.

YOUR ROLE AT SIXT

• You will design and build robust backend services in Java that power vehicle turnaround and fleet orchestration workflows
• You will contribute to the design and evolution of distributed, event-driven systems that operate at branch level and at global scale
• You will develop and maintain shared libraries and internal tooling that improve reliability and delivery speed across the BranchOps engineering team
• You will collaborate closely with product, operations, and engineering stakeholders to translate complex business workflows into scalable technical solutions
• You will actively integrate AI coding tools such as Claude and Cursor into your daily development workflow, helping to embed AI-assisted engineering as a standard practice within the team

Your Skills Matter

• You hold a B.Tech, B.E., or Master’s Degree in Computer Science or a closely related discipline
• You bring 7–9 years of hands-on experience in sophisticated engineering environments — including cloud-native application development, scalability problem-solving, and event-driven system design, ideally within a start-up or scale-up setting
• You have strong, production-proven experience with Java and Spring Boot (must-have) and are confident navigating a modern microservices landscape end to end
• You have designed or operated distributed systems and microservices architectures, with a clear understanding of the trade-offs that come with operating at scale
• You have a solid grasp of event-driven patterns, pub-sub models, and message brokers such as Apache Kafka
• 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
