## Description

As a Senior Back-end Developer, you will join our skilled, international team of developers based in Stockholm, dedicated to building next-generation products and access control solutions that enable identity, authentication and access experiences for customers worldwide.

Why this role matters

At ASSA ABLOY, technology plays a direct role in creating safer, more open environments. Your work will help make sure different product components can communicate and work together reliably - turning individual technologies into complete access solutions.

This is a role for someone who enjoys more than simply implementing requirements. You'll have the opportunity to contribute to architecture, solve challenging backend and integration problems, and continuously improve both the software and the way the team works.

The role

You'll join a small and strongly connected team working in a highly self-organised agile environment. The team values close collaboration, open discussion and learning from one another, with approaches such as pair programming and mob programming forming part of how you work together.

You'll take ownership of backend development and integrations, from designing solutions through to implementation, testing and continuous improvement. You'll also contribute to technical discussions and decisions, while having the independence to explore problems and find solutions before bringing others in.

What you'll work on

 * Build and evolve backend services - develop high-quality software using Golang and modern software engineering practices, with a focus on distributed systems and product connectivity.
 * Develop APIs and integrations - create and maintain REST APIs and modern integration patterns that connect different product components.
 * Shape technical solutions - contribute to software architecture, object-oriented design and decisions around scalable, maintainable solutions.
 * Strengthen software quality - work with CI/CD pipelines, automated testing and code reviews to help deliver reliable software.
 * Solve complex problems - troubleshoot and improve existing solutions while looking for practical ways to make the product and development process better.
 * Work closely with the team - collaborate through pair and mob programming, share knowledge and contribute to a culture of continuous improvement., Depending on the risk profile for the role, a background screening may need to be performed.
