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. It 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 selected public clouds.

General Description

Local Operations manages the on-premises production platform, which serves as the primary host for all mission-critical business applications. Local operations are responsible for the following core areas:

Platform Stability: Ensuring the high availability and performance of the on-premises private cloud environment.

Application Hosting: Consulting on the seamless operation of Germany-specific productive business applications.

Incident Management: Resolving technical issues within standard business hours to minimize operational downtime.

Lifecycle Maintenance: Executing routine updates, patches, and system optimizations within the local infrastructure.

Scope of Work

CI/CD consulting services and Operational Readiness
Objective: consulting for CI/CD pipelines and ensure operational readiness for deployments

• 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 in the specific context of providing managed Kubernetes
Objective: Ensure operational stability and responsiveness for the managed Kubernetes platform

• Monitoring system health, performance metrics, and service availability across multi-tenant environments.
• Identifying, analyzing, and resolving incidents, minimizing service disruption.
• Triggering root cause analysis and implementation of corrective and preventive actions.

Automation of operations critical standard processes following established software development lifecycles
Objective: Reduce operational toil and improve service reliability

• Address recurring operational issues by automating remedial standard operations processes
• Validation of all automated procedures following the established software development lifecycle including staging, testing, and validation reviews

Security and Compliance Enforcement
Objective: Ensure platform operations adhere to security and compliance standards
Tasks:
• Implementing monitoring and logging strategies to support audit and compliance requirements.
• Performing routine security scans and remediating identified vulnerabilities.

Profile Requirements
• The contractor must be a senior level professional with proven experience in operations management of private cloud solutions, proficiency in managing Kubernetes operations on the platform with following experience:

Must-have experience
• At least of 5 years of operational experience with self-managed Kubernetes clusters, self-managed services providing Kubernetes clusters and productive applications or systems in on premise environments on Kubernetes
• Deep understanding of networking concepts, including protocols, load balancing, and security.
• Profound knowledge and implementation experience with CI/CD processes, tooling (e.g. GitLab, Jenkins, Tekton, Argo Workflows, and Argo CD), concepts and associated quality and security assurance for software delivery
• Fundamental understanding of core operations processes (incident management, change management, problem management, IT Service Management) as well as SRE concepts
• Experience in gathering operational insights from monitoring or observability including SLI/SLA/SLO management and tracking.
• Hand-on experience in documenting procedures properly and enforcing clear runbooks or playbooks.
• Hands-on experience with monitoring and logging tools (e.g., Prometheus, Grafana, Datadog, Mimir, Loki).
