Our core focus is empowering engineers to ship code efficiently and safely. We own the CI/CD pipelines and infrastructure automation that drastically improves developer productivity. As the Lead for this team, you will define the technical roadmap for the software pipeline from idea to delivery, enabling every engineer in the company to ship at terminal velocity with total confidence. By building the foundational tools that streamline the path to production, you will play a pivotal role in maximizing developer throughput, minimizing deployment friction, and ensuring our organization can move fast without the fear of breaking things.

As a Senior Software Engineer for this team, you will drive the evolution of our CI/CD pipeline to enable seamless development and deployments across the organization:

• Scalable Tooling & Coverage: Design and build the next generation of tools that simplify CI/CD pipelines. You will lead efforts to help bring all teams and repos up to best in class standards at scale .
• Set Engineering Standards: Contribute to the standards for our repositories. You will refine the benchmarks for PRs, cycle time, velocity, code quality metrics, and systemic reliability that all teams will follow.
• AI-Driven Strategy: Spearhead our efforts to leverage AI within the CI/CD lifecycle as well as using AI to accelerate our own development efforts.
• Cross-Functional Collaboration: Work closely with internal users to understand their use cases and help roll out and act as a consultant for teams to enable them to leverage the best known good CI/CD workflows.
• Operational Excellence: Oversee the health and performance of our entire CI/CD pipeline, taking responsibility for the stability of the environment that hundreds of engineers rely on daily.
