Platform Database Engineer NoSQL / Graph Databases

SYSTABUILD is building a shared cloud and platform foundation for a group of leading software companies in the construction, CAD and ERP domain.

As a Platform Database Engineer focusing on NoSQL and Graph Databases, you will play a key role in evolving our data platform capabilities beyond traditional relational models. You will work closely with backend and product teams to design, migrate, and operate scalable NoSQL and graph-based data solutions that support complex domain relationships and high-performance workloads.

You will be part of the Platform Engineering Team, developing backend-focused platform services and enabling multiple product teams across the group.

• Design, implement, and operate NoSQL and graph database solutions as part of the central platform.

• Take technical ownership of graph data models and query patterns for complex, highly connected domains.

• Plan and execute migrations from relational or file-based data storage to NoSQL or graph databases.

• Collaborate closely with backend engineering teams to integrate database solutions into existing and new backend services.

• Evaluate and select appropriate NoSQL and graph database technologies for different product and platform use cases.

• Ensure performance, scalability, reliability, and maintainability of database solutions in production.

• Contribute to platform architecture decisions, technical standards, and best practices.

• Support and enable product teams through reviews, guidance, and hands-on collaboration.

• Strong hands-on experience with NoSQL and or graph databases such as Neo4j, Amazon Neptune, MongoDB, or comparable technologies.

• Solid understanding of data modeling for graph and non-relational data stores.

• Experience in planning and executing database migration projects.

• Good understanding of backend software architectures and data access patterns.

• Hands-on experience operating databases in cloud environments, preferably on AWS.

• Ability to work closely with distributed engineering teams and translate requirements into robust data solutions.

• Availability to work with significant overlap to business hours in Germany (CET/CEST).

• Fluent English skills are required; German language skills (spoken and written) are an advantage.

Nice To Have

• Experience with relational databases and hybrid data architectures.

• Knowledge of performance tuning and optimization for graph workloads.

• Familiarity with Infrastructure as Code, CI/CD pipelines, and DevOps practices.

• Experience with observability and monitoring of database systems.

• Exposure to backend technologies such as Node.js, .NET, or similar ecosystems and corresponding programming languages used in backend development.

Traits We Value

• Strong ownership mindset and responsibility for platform components.

• Pragmatic problem-solver with a focus on sustainable solutions.

• Ability to communicate complex technical concepts clearly across teams.

• Interest in platform engineering and enabling other teams to succeed.

• Curiosity and willingness to continuously learn and improve.

• A competitive salary package
• Individual training and development opportunities
• Flexibility in balancing office hours and remote work
• Wellpass, JobRad, and much more..
