• Design reliable multi-step business workflows, including validation, transactional behaviour, error handling and recovery
• Integrate Miles with our Agentic AI platform, Temporal and other enterprise systems
• Turn complex business requirements into clean, maintainable and well-tested backend solutions
• Work closely with Backend, AI and Workflow Engineers, Business Analysts and Test Automation Engineers to build new capabilities end-to-end

What You Bring...

• Strong professional experience building backend applications in Java
• Solid experience designing and implementing REST APIs, microservices and enterprise integrations
• Strong understanding of automated testing, including unit and integration testing
• Experience building backend systems involving business rules, transactions and complex workflows

Earn bonus points for...

• Experience with Quarkus, Temporal, saga patterns or workflow orchestration
• Experience with distributed systems or event-driven architectures
• Experience building backend capabilities for AI, automation or machine-to-machine integrations

What’s In It For You...

• Competitive salary package;
• Meal allowance provided per working day;
• Company car or mobility budget
• Fully covered private health insurance, so you can focus on what matters most;
• Hybrid working and flexible hours, giving you the freedom to shape your workday;
• A modern co-working space offering a comfortable working environment;
• From day one, you’ll be supported through a structured onboarding program, with guidance from a dedicated coach to help you get up to speed and grow in your role;
• And because strong teams go beyond day-to-day work, we regularly create opportunities to connect — from casual drinks to team activities and company-wide events
