Full Stack Developer (all genders)

Your mission - or, in other words: your tasks

• You develop and operate the portals through which our customers use their sovereign cloud - from self-service ordering and tenant management to transparency over resources, costs, and permissions.
• You design, develop, and maintain the web services and APIs (REST and SOAP) that connect these portals to our cloud platforms, CMDB, identity management, and billing systems.
• You develop and operate our central data platform, which collects, harmonizes, and enriches data from the source systems behind the cloud - inventory, monitoring, usage, and contract data.
• You deploy and operate containerized applications- running in our own certified data centers.
• You maintain and optimize our CI/CD pipelines so that deployments are automated, reproducible, and auditable.
• You keep sovereignty requirements in the code, not just in the concept: data residency, GDPR, clean role and permission models, and traceable audit trails.
• You actively shape our database architecture and data models, with a focus on performance, quality, and maintainability.
• You implement new requirements in close collaboration with stakeholders and translate them into scalable technical solutions.
• You continuously improve our platform, our development processes, and our technical standards.
• You participate in architectural decisions, review code, and pass your experience on to others.

Skills

What you bring to the table - besides the desire to make a difference

• You have experience in developing web applications and RESTful APIs with modern frameworks and technologies - whether from your studies, your first years on the job, or your own projects.
• You are confident with JavaScript/TypeScript and PHP, and shell scripting in a Linux environment doesn't scare you.
• You have solid knowledge of MySQL/MariaDB, database design, and data modeling.
• You are familiar with modern web technologies and enjoy building interfaces that people actually like using.
• You have worked with CI/CD pipelines and DevOps tooling such as GitLab or Azure DevOps - or you are keen to get properly into it.
• You are interested in containers, Kubernetes, and cloud technologies, and you find the topic of digital sovereignty genuinely relevant rather than just a buzzword.
• You are familiar with modern web technologies and enjoy creating intuitive graphical user interfaces.
• You are comfortable in both Linux and Windows environments.
• You enjoy working independently while staying closely connected to stakeholders and an agile development team.
• You are business fluent in English, written and spoken. German language skills are an advantage.

What makes it even better - but is not a must:

• You have run Kubernetes workloads in production and know your way around Helm, GitOps, or service meshes.
• You have integrated identity and access management (Keycloak, OIDC, SAML) or built multi-tenant permission models.
• You have worked with the APIs of cloud and virtualization platforms such as OpenStack, Proxmox, or VMware.
• You have dealt with SOAP and legacy interfaces and know how to integrate them without letting them dictate your architecture.
• You have been in touch with security and compliance frameworks such as ISO 27001, BSI C5, or NIS2.
• You have experience with modern frontend frameworks such as Vue or React.
