We are looking for a Backend Software Engineer (Java), mid to senior level, to join the Metadata Platform DB team. This team owns Postgres end-to-end - from infrastructure and provisioning to the software layer that sits on top of it - and is looking for someone to help maintain and grow that ecosystem.

The Team

Metadata Platform DB owns Postgres provisioning and infrastructure as code, along with a set of Java (and one Rust) components built around it, including a core client library, a database proxy, a schema management tool, and a fork of an open-source sharding solution.

The Tech Stack

• Cloud Infrastructure: Cloud-native platform, expanding beyond current AWS and Azure dependencies toward provider-agnostic deployment.
• Core Technologies: Java, Postgres.
• Infrastructure as Code: Terraform, a Go-based operator.
• Systems components: Rust (database proxy).
• Containerization: Kubernetes.
• DevOps: Kustomize, GitHub CI, ArgoCD/Kargo, Datadog for metrics/logs/APM.

The Work You'll Do

• Take ownership of one or more Java components in the Postgres ecosystem, including newly onboarded ones.
• Work alongside the infrastructure-as-code side of the stack (Terraform, operators) to understand how your components are provisioned and operated.
• Improve reliability, performance, and security of the components you own.
• Where applicable, maintain forks of open-source projects - tracking upstream changes and making deliberate calls about merging versus diverging.
• Collaborate with teams handing off components and with downstream consumers.
• Document processes, concepts, and decisions as ownership transitions and components evolve.

The Qualifications You Need

• Solid professional experience building Java applications (3+ years mid-level, 7+ years senior).
• Experience with infrastructure and IaC concepts - comfort working with or alongside Terraform or similar provisioning tooling.
• Experience building, packaging, and debugging applications in containerized and Kubernetes environments (Docker/OCI).
• Experience with databases (Postgres preferred over InnoDB/MySQL, with a good grasp of Postgres MVCC and concurrency mechanics from an application perspective) and distributed systems.
• Experience writing and maintaining unit and integration tests.
• Strong communication skills in English and a passion for clean, maintainable code.

Nice to Have:

• Experience with Rust or Go.
• Experience maintaining a fork of an open-source project.
• Hands-on Terraform experience.
• Experience with monitoring and log analysis tools (e.g., Datadog).
• Familiarity with agentic coding tools (e.g., Claude Code, Cursor, Codex).

What Celonis can offer you:

• Pioneer Innovation: Work with the global leader in Process Mining and the Process Intelligence Graph to shape the future of AI-driven business operations.
• Ownership from Day 1: Every full-time "Celonaut" is an owner, receiving Restricted Stock Units (RSUs) and merit-based refresh grants.
• Unrivaled Family Support: Benefit from our inclusive parental leave policy—24 weeks of fully paid leave for primary carers and 12 weeks for supporting carers, available from your first day of employment.
• Work-Life Integration: Enjoy Unlimited PTO (in applicable regions) and generous PTO globally, as well as a flexible hybrid work model that balances remote focus with vibrant office collaboration.
• Continuous Growth: Elevate your skills through our 70-20-10 learning framework, mentorship programs, and access to a dedicated learning platform.
• Holistic Well-being: Prioritize your health with subsidized Wellhub memberships, mental health counseling, and dedicated "Wellness Weeks" that prioritize work/life balance.
• Drive Sustainability: Participate in annual Impact Days, where you receive paid time off to volunteer for community and environmental causes with your local office, or virtually.
• Global Inclusion & Belonging: Find community through our Inclusion Think Tank and participate in our annual Inclusion Days, ensuring every voice is heard and valued.
• Value-Driven Impact: Join a mission-led organization where our core values—Live for Customer Value, The Best Team Wins, We Own It, and Earth Is Our Future—drive every decision.
