Java Software Developer jobs in Germany

idealo is currently looking for a Mid-Level Software Engineer to join our mission of becoming Europe’s best platform for smart shopping decisions. If you value a team culture based on openness, respect, integrity, and trust — this might be the perfect role for you!

We are Team Reach Enablement. Our mission is to empower idealo’s marketing channels with high-quality product and offer data, ensure accurate billing of paid traffic, and enable reliable tracking to make marketing initiatives measurable and effective.
In short: our work lays the foundation to bring millions of customers to idealo.

To achieve this, we rely on a modern, event-driven architecture using Kafka, REST APIs, NoSQL databases, and microservices written in Kotlin. Our system landscape runs entirely on AWS. We own the full lifecycle of our services — from design and development to deployment and monitoring.

The position is available in full - or part-time.

• You take an active role in designing, implementing, and maintaining robust, scalable microservices using Kotlin/Java and related technologies.

• As part of our DevOps culture, you take end-to-end ownership — from concept to deployment and monitoring.

• You shape our infrastructure and development processes by contributing to CI/CD pipelines, observability, and Infrastructure as Code.

• You collaborate closely with stakeholders from marketing and across idealo to deliver reliable, performant tracking and billing systems.

• You write clean, maintainable, and well-tested code, and you’re comfortable with pair programming and code reviews.

• While your focus is on the backend, you’re open to contributing to frontend tasks when needed — frontend experience is a plus.

Technical Skills

• Solid experience with Java and Kotlin, particularly with Spring Bootand building Restful APIs.

• Familiarity with event-driven architectures (Kafka) and distributed systems is a plus.

• Experience working in Kubernetesenvironments, ideally in cloud infrastructure (preferably AWS).

• Hands-on experience with Infrastructure as Codetools (e.g. AWS CDK, Terraform).

• Comfortable operating and monitoring your own applications — you value ownership and reliability.

• Bonus: Experience with CI pipelines (e.g. GitHub Actions).

• Nice to have: Frontend development skills using TypeScript/JavaScript.

Mindset and people skills

• You proactively share knowledge, foster a collaborative team culture, and help others grow.

• You thrive in agile, autonomous teams, enjoy exploring new technologies, and continuously challenge the status quo.

• Good English communication skills round out your profile and help you collaborate effectively across teams.

You don't tick all the boxes? Don't worry, we are looking for employees who convince us with their personality and are motivated to go on full power with their team!

• You need vacation? We offer you 30 days of vacation. Not enough? You can "buy" an additional 15 days every year by converting your salary and it's seen as a positive thing.

• You want to further your education? We take your personal development goals seriously and, in addition to our idealo Learning Hub, eLearning offerings (e.g., Udemy), coaching & mediation, we also offer you the opportunity to benefit individually from additional learning and development budget.

• And what about the office? Our office in the heart of Berlin offers free organic breakfast, excellent free lunch (vegan and vegetarian), as well as free coffee, lemonades and after-work beer, in addition to the "standard foosball". It also has a fabulous rooftop terrace with view of the whole of berlin where you can network with colleagues from our group of companies.

• In need of additional support in any areas of your life? We offer free counseling and support in all areas of life (professional, private, family, health, etc.) in cooperation with the pme-Familienservice.

• You want full flexibility on your way to work and beyond? No problem with a job bike or Deutschlandticket- and it's environmentally friendly, too!

• Want to keep yourself fit? We offer many different fitness and sports options, such as an Urban Sports or Gympass membership, to suit your personal needs.
