About this role
**Grafana Labs — Senior Full Stack Engineer (Experimentation / Product Analytics)** Grafana Labs builds **Grafana Cloud**, a fully managed observability platform trusted by 10,000+ organizations. This role is **full-time and remote**, considering candidates from **US & Canada only (EST time zone)**. --- ## The opportunity Grafana Labs is building a **native experimentation platform**: a Grafana app that helps teams define **A/B tests**, connect them to **feature flags** and **product telemetry**, and get **statistically sound answers** about what changes actually did. You’ll join the **Product Analytics team** and serve as the team’s dedicated software engineer—**owning the experimentation app end to end** (React frontend + Go backend) and shipping production code. This is **not** an analyst role. --- ## What you’ll be doing - **Evolve the experimentation app from internal tool to product**: full ownership across frontend + backend, from design to rollout and iteration. - **Build the experimentation experience**: workflows for hypotheses, experiment/metric configuration, lifecycle management, and result exploration. - **Make instrumentation easier to adopt and trust**: evolve the experimentation SDK and integrations (OpenFeature, Faro), and ensure consistent identity + event contracts. - **Connect experiments to the rest of Grafana’s UX stack**: integrate with Faro + Frontend Observability so exposures/outcomes are captured automatically and linked to Session Replay. - **Harden the statistics and analysis path**: extend the statistics engine for scalability, cost-awareness, and correctness (e.g., server-side computation, scheduled analysis, health alerting, guardrails). - **Use AI where it genuinely helps**: extend Grafana Assistant for authoring, explaining, and reporting on experiments. - **Raise the engineering bar**: mentor teammates, write ADRs/docs/demos, and help others adopt experimentation. - **Own what you ship**: participate in on-call and support internal teams running experiments. --- ## Tech you’ll work with - **Frontend**: TypeScript + React app plugin using `@grafana/ui`, plus a custom datasource plugin. - **Backend**: **Go** with the Grafana App SDK; experiments modeled as Kubernetes-style custom resources defined in **CUE** (operator, admission webhooks, declarative/GitOps management). - **Feature flags**: **OpenFeature** + **OFREP**, Grafana’s multi-tenant feature toggle service, and an embedded Go feature flag evaluator. - **Statistics engine**: Bayesian analysis (TypeScript with a Go port) producing verdicts, probability-to-be-best, credible intervals, expected loss, and sample-size recommendations. - **Data**: exposure/outcome events via RudderStack → BigQuery, or Grafana Faro → Loki; queried through Grafana datasources. - **AI**: Grafana Assistant for experiment authoring support. --- ## What makes you a great fit - Strong **full-stack** experience building and operating production web apps with **TypeScript/React** and backend services in **Go** (or similar, with willingness to work in Go). - Experience building an **experimentation platform** (or integrating one) such as Statsig, Eppo, GrowthBook, Optimizely, LaunchDarkly, etc. - Product + data intuition: you care about whether shipped work moved the needle; comfortable with event data, SQL, and warehouses like **BigQuery**. - Technical ownership and ability to deliver complex projects with short feedback loops. - Operational responsibility: on-call ex
