The Knowledge Graph is a suite of distributed, multi-tenant microservices that connects signals across the stack and delivers automated Root Cause Insights by actively analyzing Metrics, Traces, and Logs stored in Grafana Cloud. These services process and store data across SQL, graph, and time-series databases and are designed for high availability and scale. Used by thousands of self-service customers and trusted by some of the world’s largest organizations to monitor mission-critical infrastructure, the Knowledge Graph is a foundational platform at Grafana. As adoption continues to grow, our focus is on continuously improving performance, increasing reliability, and scaling efficiently—without compromising on quality.

Qualifications - You are a motivated self-starter with a bias towards action. - You have strong coding skills and operational experience; you were responsible for operating the software you have built. - You have worked on a SaaS platform and dealt with common distributed systems problems (e.g. scalability, multi-tenancy, data isolation, HA, …). - You have excellent written and spoken communication skills.

We build everything with our users in mind. Requirements - Work with your team to build and roll out new features, then use the results to iterate and improve. - Drive projects from initial ideation all the way to operations once it is in the hands of customers. - Take on complex challenges and break them down to achieve short feedback loops: to analyze, design, and build modular solutions, deliver MVPs, gather data and feedback, and then progress iteratively. - Maintain critical systems, and own their reliability, performance, and availability. - Be a part of your team’s on-call rotations and take ownership of the services you’re running. - Mentor and support other team members, participate in design discussions, and collaborate with the team. - Learn new skills by gaining a deeper understanding of our cloud product and our customers and getting to know the codebase. - Take an active role in influencing our roadmap and your own career objectives.
