Job technologies
Your role in the team
- Full-stack development: You develop sophisticated Java and web applications across the frontend and backend, both in modern Spring environments and in Jakarta EE.
- You actively contribute your experience to customer projects and work with our customers to develop suitable, sustainable solutions.
- A bridge-builder between the old and new worlds of Java: You’re familiar with both established enterprise application landscapes and classic Jakarta EE architectures, as well as modern Spring, cloud, and microservice architectures.
- You understand the strengths and challenges of both worlds and can gradually transform existing applications and architectures into modern, future-proof solutions.
- Architecture & Modernization: You think not only in terms of technologies, but also in terms of sustainable architectures.
- You analyze existing systems, identify opportunities for modernization, and develop strategies for evolving legacy applications in a meaningful way—without unnecessarily discarding solutions that are already working.
- Quality & Engineering: Clean code, test-driven development, and DevOps are part of professional software engineering for you and an integral part of your daily work.
- Technology & Innovation: You are interested in current technologies, architectures, and trends and assess how they can be used effectively.
- At the same time, you know that modern software development in enterprise environments often builds on existing systems, and that not every solution starts from scratch.
- Problem-solving: You analyze complex technical challenges, optimize existing solutions, and find pragmatic ways to connect legacy systems with modern technologies.
- Collaboration: You work closely with colleagues and other teams, actively contributing your technical expertise to develop the best possible solution for our customers together.
- Consultant role: You’re not just a developer, but also a technical consultant.
- You understand our customers’ requirements, challenge existing approaches, and support them in sustainably evolving their applications and architectures.
- Professional development: You have the opportunity to grow professionally and personally through hands-on training—particularly in software architecture, modernization, and cloud technologies—as well as regular knowledge sharing in our guilds.
Our expectations of you
Qualifications
- You have in-depth knowledge of modern Java development with Spring, particularly Spring Boot and Spring Cloud.
- You understand the differences and relationships between traditional and modern Java architectures and have ideally already modernized applications or systems or supported their migration to new architectures.
- You can familiarize yourself with existing, complex system landscapes as well as design and implement new technical solutions.
- Your strong self-organization, team spirit, and excellent problem-solving skills set you apart.
- You speak German at a native level and communicate confidently in English.
Experience
- You have several years of experience in full-stack development, with a strong focus on backend development in Java, ideally complemented by Kotlin or Python.
- At the same time, you have in-depth experience with Jakarta EE and traditional enterprise application environments, and are familiar with application servers such as JBoss and WebSphere.
- You have regularly taken on frontend development tasks and ideally have experience with React or Angular, as well as JSF or PrimeFaces.
- You have experience with CI/CD pipelines, containerization, and cloud services.
- Ideally, you already have experience managing (sub-)projects.
What we offer
- Exciting projects: You’ll work on a diverse range of client projects in a professional consulting environment, where you can contribute your experience and ideas, take on responsibility, and use your initiative to become a game changer on the project.
- Flexibility: Tailor your working day to your needs with remote work and flexible working hours.
- We meet in person once a week to connect and spend time together.
- Share knowledge & grow together: Whether through our architecture school, Skill Factories or guilds, there are plenty of opportunities to build and share knowledge and learn from one another.
- You can contribute your experience and help shape your colleagues’ professional development.
- Team spirit: Look forward to an open and collaborative environment where we support one another, share knowledge, and value different perspectives.
- Health & Benefits: You benefit from Corporate Benefits, JobRad, a subsidy for your public transport pass and—by individual agreement—Urban Sports Club.
- Our weekly “Active Break” also brings movement and mobility into your workday—whether you’re in the office or working from home.
- An office you’ll love: A bright, modern workspace, great coffee, a selection of teas, a well-stocked drinks fridge, plus fresh fruit and sweet snacks—we’ve got all the extras covered, too.
- Shared experiences: Whether it’s a regular get-together, game night, annual kickoff, or summer party, we regularly have opportunities to get to know our colleagues outside of day-to-day project work.
