## About the Role

You bring deep build system expertise alongside an SRE mindset. You are systematic in how you approach fault isolation and root cause analysis, and you apply SLO-driven thinking to build reliability and developer productivity. You thrive on high variety - ML, compilers, kernel drivers, simulators, hardware verification - and you understand that your work becomes the foundation every engineer at Fractile builds on. You take that responsibility seriously., * 5+ years in software or infrastructure engineering

 * 3+ years working with build systems
 * Strong hands-on experience with Bazel
 * Python scripting and automation skills
 * Experience with CI/CD for large-scale products, including debugging and resolving pipeline failures at scale
 * Familiarity with infrastructure monitoring and observability tooling (e.g. Prometheus, Grafana, Datadog, or similar)
 * Working knowledge of SRE principles - SLOs, alerting design, incident management, and on-call practice

## Description

As a DevOps Engineer you will design and own Bazel rules and extensions across the stack, scale our monorepo as we grow across Python, C++, Rust, SystemVerilog, and ML workloads, and create reproducible multi-language build pipelines. You will debug and triage CI pipeline failures, optimise CI performance across large compute clusters, build and maintain infrastructure monitoring and observability tooling, and define alerting thresholds, runbooks, and incident response workflows for build and CI infrastructure. You will contribute upstream to Bazel rules we depend on and help shape the developer experience for every engineer at Fractile.
