Senior Integration Engineer (Zagreb)

* Please note that most of the time you’ll work fully remote, except in occasional circumstances. 

The Middleware area at Xpand IT helps clients improve business processes from end to end by implementing software solutions that enable several applications/components of a distributed system to communicate and manage data in an efficient and scalable manner. By design, these solutions enable interoperability between applications that may run in different operating environments (operating system or cloud provider) and communicate by exchanging data based on industry standards (JSON, XML, etc).


As a Senior Integration Engineer, you will play a central role in the team, since you’ll be responsible for building the core system of the entire solution architecture. From business requirements to production deployment, you will be aware of every detail of the end solution. You will also be responsible for designing and implementing it in compliance with best practices using microservices-based architectures deployed in cloud environments.

Your daily activities will include:

  • Participating in technical and functional analysis of complex and enterprise-wide integration architectures
  • Playing a key role in outlining requirements along with the architecture team and backend systems stakeholders
  • Ensuring that delivered code (own and team’s) is part of scalable solutions and that can be reused in the future and is compliant with enterprise integration best standards
  • Analyze and integrate inputs from different stakeholders
  • Actively participating in the design and evolution of APIs & tools according to the team’s roadmap
  • Working with team members to provide insight into solving complex problems while leveraging enterprise and industry best practices (including scalability, availability, maintainability, flexibility, governance and reusability)
  • Validate deliverables and ensure overall solution quality
  • Supporting the process of migrating platforms and applications to production environments
