Senior Software Engineer - Session Replay

The Opportunity

The Session Replay squad is building a new Grafana Cloud product that helps our customers to understand what users actually experienced when something goes wrong. Session Replay connects frontend signals to concrete session-level evidence, enabling faster and more confident investigation of production issues.

This team works at the intersection of:

• Frontend observability
• Backend data processing and storage at scale
• Debugging workflows across products
• Privacy and access control
• Performance and cost constraints at scale

A key part of our next phase is evolving the backend architecture of capturing sessions, including a migration toward a columnar/analytical solution as a primary storage and query engine for high-volume session data. Our stack is Golang, TypeScript, and React.

What You’ll Be Doing

• Own end-to-end technical direction for Session Replay, spanning frontend, backend, and data systems.
• Drive the evolution of our backend architecture, including designing systems around columnar/analytical data storage for large-scale session data and defining data models, ingestion pipelines, and query patterns.
• Lead the design of investigation workflows, connecting replay with logs, metrics, traces, and other telemetry.
• Make high-leverage architectural decisions that impact multiple teams and products.
• Partner with teams across Grafana to build cohesive cross-product experiences.
• Engage directly with customers through calls, feedback gathering, and adoption support.
• Improve engineering standards and mentor engineers.

Technologies You'll Work With

• Go (backend services and APIs)
• Columnar/Analytical data storage
• Object storage (S3, GCS, Azure Blob Storage) and MySQL
• TypeScript / React
• Grafana ecosystem (Mimir, Loki, Tempo, etc.)
• Modern AI coding assistants and frontier models

What Makes You a Great Fit

• Comfortable working in a remote-first company with strong written and spoken English communication skills.
• Collaborative, friendly, kind, respectful, and able to operate by consensus.
• Ability to reason about data-intensive systems (ingestion, storage, querying, cost trade-offs).
• Comfortable owning features in ambiguous problem spaces.
• Understanding of user-centered software development processes.
• Value code maintainability, readability, and automation.
• Use AI tools as a natural part of your engineering workflow.
