Senior Backend Engineer | Mimir OSS | Spain | Remote at Grafana Labs

**Who this is for** This role is perfect for a Senior Backend Engineer who thrives on high-scale distributed systems and open-source development. You should be a strong Go developer (or proficient in C++/Rust/similar) with a deep understanding of cloud-native infrastructure. Since you'll be working on Grafana Mimir, an ideal candidate has a "systems thinker" mindset—someone who enjoys optimizing performance, resilience, and reliability at a massive scale. **Key highlights** Grafana Labs offers a premier remote-first culture with high levels of autonomy and transparency. For residents of Spain, the salary is clearly defined, and the package includes Restricted Stock Units (RSUs), giving you an ownership stake in the company. You'll also benefit from a generous 30-day annual leave policy and "shutdown days" designed to prevent burnout. **You might be a good fit if you...** * Have experience building and operating large-scale distributed systems or microservices. * Are comfortable with a "DevOps" model, including participating in on-call rotations for the services you build. * Value open-source contributions and want to work on a project used by millions globally. * Enjoy breaking down complex architectural challenges into iterative, manageable MVPs.
