Im Rahmen eines innovativen Plattform Projektes im Energiesektor suchen wir im Auftrag unseres Kunden nach Unterstützung als Senior Operation Engineer (m/w/d) mit 3 Jahren On Premise Erfahrung im Kubernetes Umfeld. Die Tätigkeit erfolgt weitestgehend Remote und nach Absprache ca. 1 mal im Monat für paar Tage am Stück in Frankfurt oder Berlin.

Project Description

The team is building an internal platform for software product developers to accelerate the development and delivery of software products to tackle the massive challenges facing the energy sector. The Platform is a service oriented, cloud-native platform that is being built to provide application teams with self-service capabilities to develop, run and operate their software products. Platform provides services for application infrastructure, data, service lifecycle management, application build and delivery as well as services to operate their software products. The Platform is deployed as a hybrid cloud, encompassing both private cloud and select public clouds.

General Description

The Product Line is responsible for a product portfolio , consisting of an Infrastructure as a Service Product, a managed Kubernetes Service, a resource management service to facilitate scalable management of platform permissions and

a service lifecycle workflow engine enabling. All services together constitute a core part of an on-premise private cloud platform for all business applications , including IT/OT critical applications required for maintaining and operating the grid.

For the whole product portfolio, the product line owns the complete product flow, from product management, architecture, delivery up until Tier 3 operations.

CI/CD and Operational Readiness

Objective: Support on CI/CD pipelines and ensure operational readiness for deployments

Tasks:

• Validation of deployment artifacts from an operations perspective.

• Defining and enforcing quality assurance measures (e.g. required documentation of standard operation procedures,

successful test reports, …) to ensure the high quality of delivered products and services.

• Ensuring rollback strategies and operational monitoring (observability) are in place for production deployments.

Monitoring, Incident, Problem and Change Management

Objective: Ensure operational stability and responsiveness

• Monitoring system health, performance metrics, and service availability across multi-tenant environments.
