About The Role

This is a rare opportunity to join Rootly as an early engineer and fundamentally shape our trajectory.

What You’ll Do

• Embed with product teams to enhance observability, reliability, and performance of their services.
• Own our CI/CD pipelines, observability tooling, monitoring systems, and incident response processes.
• Build tools and automation to eliminate manual toil, improve engineering velocity and developer experience, and improve system reliability.
• Collaborate deeply across engineering to understand systems at the code level and surface cross-cutting reliability, performance, and scaling concerns early.
• Architect and scale our infrastructure, ensuring best-in-class performance, availability, and operational excellence.
• Drive capacity planning efforts to ensure our infrastructure is resilient and scalable as we grow.
• Define and manage SLOs and error budgets in partnership with Engineering teams who own production services.
• Act as a strong voice for reliability, performance, and scalability across the engineering organization.
