Job description

Do you know that we are one of the TOP 15 e-commerce companies in Germany? We look for strengthening in Remote.

(Senior) Software Developer m/w/d Kotlin

That’s what you’d have to do:

One of the big players in the German e-commerce scene and European online printing – that’s us: FLYERALARM. Since our founding in 2002, we have turned the printing industry upside down. Today, our company has more than 2,500 employees who give their all every day – at a total of 15 production sites in Germany. Do you want to be a part of it? Then definitely keep reading.
To strengthen our team, we are looking for a Professional or Senior Software Developer m/f/d Kotlin.
In this role, you will develop end-to-end, within an agile team, our complex, inhouse software solutions (backend-based web applications) for managing, providing, and processing the purchasing and sales conditions (including pricing, delivery times, availability, etc.) of our products, which are sold in our webshops in 12 countries. You will further develop and design our core system with Kotlin in Spring Boot and work in the team, following the “You build it, you run it” principle, so that the environment remains maintainable, available, and scalable, and can be deployed as automatically as possible (in the AWS Cloud) using GitLab. AI is becoming increasingly important for us, so you will consciously use Claude Code and continue to expand its everyday use. And because you should stay on top of things, there’s the opportunity to exchange ideas with like-minded people at professional conferences.
