• Knowledge of compiler toolchains (GCC, Clang) and cross-compilation workflows
• Proven experience managing build architecture at massive scale (e.g., hundreds of thousands of builds)
• Working knowledge of Infrastructure as Code (IaC) tools such as Ansible, Terraform, and similar

Responsibilities

• Design and implement modern distributed build tooling and caching mechanisms to reduce CI build times from hours to minutes; actively diagnose and remediate cache failures, misses, and cache poisoning
• Continuously analyze build scan data to identify trends and recurring failure modes, shielding developers from costly context switching
• Diagnose non-hermetic and non-deterministic build behavior and develop defensive mechanisms to prevent future occurrences
• Tune and optimize builds for the unique constraints of containerized and cloud-native environments
• Serve as a governing authority on tool usage across teams, defining and enforcing best practices for clean, reproducible, large-scale builds
• Continuously upgrade systems and align build infrastructure with the latest ecosystem best practices
