Atlassian Suite System Architekt (m/w/d) IAM and Kubernetes Know How

Responsibilities

• Design the target architecture for Jira, Confluence, and JSM on Kubernetes
• Provide definitions for a multi‑tenancy model (logical isolation, shared platform)
• Conceptualize high availability, scalability, and failover strategies
• Define system boundaries, interfaces, and ownership models
• Coordinate architecture with private‑cloud constraints and infrastructure standards

Identity and Access Architecture

• Integrate Atlassian tools with Keycloak or equivalent IAM
• Define internal vs. external identity separation
• Establish consistent role and permission models across tools

Secure External Access

• Define access patterns for external users
• Design ingress and authentication flows
• Define data separation and exposure boundaries
• Ensure audit logging and traceability of external interactions

Integration Architecture

• Design integration patterns with monitoring/alerting systems (e.g., Prometheus)
• Integrate with CMDB systems, notification services, and external ticketing systems
• Define API and/or event‑driven integration models
• Establish data ownership and synchronization boundaries

Reliability, SLOs, and Observability

• Conceptualize SLAs and SLOs for the Atlassian platform
• Provide monitoring and alerting concepts
• Integrate with observability tooling (e.g., Prometheus)
• Define incident detection mechanisms

Release and Change Management Strategy

• Design upgrade and release strategies for Atlassian tools
• Manage version compatibility (especially plugins)
• Follow standardized staging and validation processes
• Establish safe rollout mechanisms

Architectural Governance and Alignment

• Coordinate with platform architecture, security, and stakeholders
• Enforce architectural standards and guidelines
• Document architecture and decisions in a structured manner

Requirements

• Proven experience designing Jira, Confluence, and/or JSM in enterprise environments
• Strong architectural mindset with the ability to translate ambiguity into structured solutions
• Hands‑on attitude; able to work closely with engineering teams
• Experience in platform thinking (treating internal tooling as a product)
• Ability to balance standardization vs. flexibility, security vs. usability, stability vs. speed of change
• Strong stakeholder communication across technical and non‑technical audiences
• Hands‑on experience with Kubernetes‑based platforms
• Experience with IAM and identity federation (e.g., Keycloak or similar)
• Experience designing multi‑tenant platforms
• Knowledge of secure system exposure (reverse proxies, ingress, authentication flows)
• Understanding of plugin/extension management risks in Atlassian ecosystems
• Experience defining SLAs/SLOs and monitoring/alerting concepts (e.g., Prometheus)
• Fluent English (spoken and written, at least B2 level)

Preferred Experience

• Operating Atlassian tools in private cloud or regulated environments
• Familiarity with compliance frameworks
• Integrating Atlassian tools with CMDB systems, external ticketing systems, and DevOps platforms (e.g., GitLab)
• Building self‑service platforms with templates and onboarding workflows
• Governing plugin approval processes
• Designing external‑facing service platforms (e.g., customer portals, partner integrations)
• Familiarity with observability stacks and incident management practices
