Overview
As the IT of the REWE Group Austria, we collaborate with over 700 employees to develop innovative IT products and services for all our corporate divisions in Austria and abroad. This role is part of the Integration Platform Team at REWE International AG, where we build Go‑based Kubernetes operators and platform APIs that automate provisioning, orchestration, and lifecycle management of platform services.
Responsibilities
* Design, implement, test, and extend Go‑based Kubernetes Operators that make services such as Kafka available through self‑service.
* Work on existing operators and help design new ones, including APIs, internal structure, tests, and long‑term maintainability.
* Use Custom Resource Definitions, controllers, and reconciliation logic to automate platform tasks in a Kubernetes‑native way.
* Build reliable self‑service features that work across multiple Kubernetes clusters and are easy for development teams to use.
* Collaborate with platform engineers and product teams to understand needs and build practical, reliable, and user‑friendly solutions.
* Discuss technical designs, document decisions, and collaborate with teams across countries and organizations.
Qualifications
* Strong proficiency in Go or a comparable language such as Rust, Java, or C++; write clean, testable, maintainable code.
* Deep understanding of Kubernetes internals, including the controller/operator pattern, Custom Resource Definitions, and the reconciliation loop; hands‑on experience building or extending operators is a strong plus.
* Experience with architectural documentation and modelling approaches (arc42, UML, C4 model, ADRs, or similar); communicate technical designs clearly to engineers and stakeholders.
* Experience writing automated tests and designing software that is easy to understand, extend, and operate over time.
* Practical experience with Prometheus and Grafana or comparable observability tooling; instrument services and set up meaningful alerts and dashboards.
* Familiarity with core Apache Kafka concepts (topics, consumer groups, partitioning, replication) and production operations.
* Familiarity with GitOps workflows and CI/CD pipelines in a Kubernetes‑native context.
* Proficiency in English at B2 level or higher.
Benefits
* Flat hierarchies and short decision‑making channels.
* Family‑friendly culture with flexible working hours and remote work options.
* Training and development opportunities (5% of working time for self‑organized training).
* Lunch allowance.
* Staff shopping and travel discounts.
* Extensive workplace wellness programme, including fitness classes.
* A competitive annual gross salary starting at €60,000 with potential for higher pay based on experience.
We promote a diverse and inclusive work environment. Therefore, we welcome applications from people of different gender, age, cultural or social background, sexual identity and from people with disabilities. In addition, we aim to increase the proportion of women in technical professions and are particularly pleased to receive applications from women for this position.
