. API Java MongoDB Python Agile NoSQL Kubernetes Kotlin REST TypeScript PostgreSQL Terraform Kafka LESS Office

Your Tasks

Customer Order Services (COS) is the strategic backbone for customer order data and processing at MediaMarktSaturn. It consolidates order information, standardizes access through a common API model, and orchestrates fine-grained workflows that power the end-to-end online order journey. Positioned as the main communication layer, COS connects the Order Management Systems (OMS) with major corporate applications — such as SAP Retail, Checkout, Payment systems, Invoicing applications, and Pick-and-Pack solutions — ensuring consistent, real-time order processing across the enterprise.

Responsibilities & Duties

• Design, implement, and evolve COS REST APIs and event schemas (OpenAPI, API Gateway), enabling contract-first integrations and decoupling consumers from Order Management platform.
• Develop and orchestrate event-driven order workflows with Kafka/Kafka Streams and Temporal (basket-to-order, payment/checkout, digital activation, fulfillment, transport management), ensuring reliability, idem-potency, and auditability.
• Build and maintain data persistence and propagation: model order data in Protobuf, MongoDB, PostgreSQL, drive real-time synchronization to corporate systems, and support analytics via Pub/Sub to BigQuery with strong data quality and PII safeguards.
• Operate the platform on GCP/Kubernetes using GitOps (Flux): monitor and troubleshoot production, optimize performance and scalability, manage incidents, and continually improve SLAs, security, and resilience.
  
  

Your Profile

• Strong experience building event-driven, distributed systems
• Proficiency in Kotlin on the JVM; solid Java skills; familiarity with Python or TypeScript is a plus.
• Proven track record designing contract-first RESTful APIs with OpenAPI, including versioning, error models, and API gateway policies (e.g., Kong/Apigee).
• Practical experience with relational and noSQL databases (like MongoDB and PostgreSQL), schema design, transactions, performance tuning in high-throughput environments.
• Experience in cloud-native operations, e.g. on GCP with Kubernetes and Terraform; GitOps (Flux), CI/CD, observability (logging, metrics, tracing), and production troubleshooting.
• Integration expertise using synchronous and asynchronous patterns (Kafka, Google Pub/Sub, etc.) across enterprise systems
• Strong focus on reliability, security, and compliance for customer order data (SLAs, auditability, PII/GDPR), with clear communication and cross-functional collaboration skills.

• Technical Mentor: You elevate the engineers around you through thoughtful code reviews, collaborative pair programming, and a commitment to sharing best practices.
