Grafana Labs is the company behind Grafana Cloud, the fully managed observability platform trusted by more than 10,000 organizations to ensure reliability, resolve incidents faster, and optimize telemetry at scale. Built on open source and open standards and designed for interoperability across any stack, Grafana Cloud brings AI to observability and observability to AI.

Senior Software Engineer - Session Replay

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 (errors, performance, synthetic checks) to concrete session-level evidence.

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.

What You'll Be Doing

As a Senior Software Engineer, you will operate as a technical leader and systems thinker, driving both product direction and architectural evolution:

Own end-to-end technical direction for Session Replay, spanning frontend, backend, and data systems.
Drive the evolution of our backend architecture: Designing systems around columnar/analytical data storage for large-scale session data, defining data models, ingestion pipelines, and query patterns.
Lead the design of investigation workflows, connecting replay with logs, metrics, traces, and other telemetry across Grafana Cloud.
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 — joining calls, gathering structured feedback, and helping customers instrument and adopt Session Replay successfully.
Improve engineering standards, patterns, and operational practices within the team.
Mentor engineers and help grow technical leadership.

Technologies You'll Work With

Go (backend services and APIs)
Columnar/Analytical data storage (core data storage and querying)
Object storage (S3, GCS, Azure Blob Storage) and MySQL
TypeScript / React (user-facing workflows)
Grafana ecosystem (Mimir, Loki, Tempo, etc.)

What Makes You a Great Fit

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

Bonus Points For

Experience with columnar/analytical databases.
Experience with observability tools (Grafana, Datadog, New Relic, Sentry, etc.).
Experience building debugging or developer-focused tools.
Familiarity with privacy, security, and access control in data-heavy systems.
Experience working on performance-sensitive systems.
