Kotlin/Java Developer

At Mindbox we connect top IT talents with technology projects for leading enterprises across Europe.

Join Our Team as a Kotlin (or Java) Developer!

Are you passionate about building modern, scalable applications and APIs? Do you want to work on innovative projects in a collaborative environment? If yes, this role is for you!

The Developer Experience (DevX) Standards and Controls function is creating a platform for control owners and development teams to manage and view their compliance with a range of software development controls.

You will work on Kotlin and Java-based web applications and APIs within one of several applications or PoCs, depending on your experience and fit. All solutions are built using a microservice architecture and modern coding techniques.

Sounds like your kind of challenge?

What You'll Be Doing

• Collaborate with developers, testers, and the wider organization to build and run products.

• Proactively resolve customer issues and respond to feature requests.
• Build APIs and microservices that solve impactful business problems.
• Deliver rapid iterations in an agile CI/CD environment.
