Sr. Site Reliability Engineer

About Backblaze Backblaze is the object storage leader in the open cloud movement, fueling customer success with cloud storage built purposefully to unlock budgets, unburden administrators, and unleash innovators. Together with our partners, we’re helping customers break free from the restrictive, overpriced legacy solutions that hold them back, and blaze forward with the full power of the open cloud in their hands.

Founded in 2007, we scaled the business with less than $3 million in outside funding until 2021, when we did a traditional IPO on the Nasdaq stock exchange. Today, Backblaze generates over $100m in revenue and is the leading specialized storage cloud – managing over three billion gigabytes of data storage for 500K+ customers in 175+ countries, including businesses, developers, IT professionals, and individuals. But while there is a lot to celebrate in our past, there is almost as much opportunity ahead of us.

What You’Ll Do:

• Service Reliability & Operations.
• Own and drive the availability, durability, and performance of critical services across all production environments.
• Lead and champion complex projects from problem discovery through complete, cross-functional resolution, demonstrating high-level technical ownership.
• Define, establish, and enforce service health standards, including working with engineering leadership to implement SLIs, SLOs, and error budget policies for multiple services.
• Lead critical incident response and post-incident reviews, translating findings into strategic, long-term service improvements and architectural changes.

• Design and architect scalable automation solutions to eliminate toil and improve the efficiency of operational tasks across the entire platform.
• Drive the strategic direction of monitoring, logging, and alerting frameworks (e.g., Prometheus, Grafana, Catchpoint, ELK), and integrate them for comprehensive observability.
• Build, maintain, and secure advanced CI/CD pipelines, configuration management, and complex infrastructure as code solutions (Terraform, Ansible, Jenkins).
• Write production-grade code (Bash, Python, Go, etc.) to develop new reliability tools and enhance existing systems.
• Collaboration.
• Act as a principal partner to engineering, product, and operations teams, consulting on resilient system design, architecture, and operation.
• Lead and formalize the Production Readiness Review (PRR) process, ensuring robust operational handoff for all new services and features.
• Lead capacity planning and disaster recovery strategy across critical infrastructure components.
• Manage the relationship with vendors and service providers to troubleshoot systemic issues and ensure strict adherence to SLA performance.
• Drive the creation of high-quality documentation, proactively share advanced learnings, and cultivate a reliability-first engineering culture across teams.
• Continuous Improvement.
• Own the creation, maintenance, and dissemination of operational playbooks, runbooks, and detailed system documentation.
