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.
What You'll Achieve: Key Responsibilities
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.

- Master of Root-Cause Analysis: You don't just fix symptoms; you hunt down systemic failures. You excel at debugging deep-stack issues and transforming those lessons into automated preventions.
- Technical Generalist: You are comfortable working across the stack. Whether it is debugging a React component in an E2E test or optimizing a Python integration test, you are ready to dive in.
- AI Visionary: You are passionate about the intersection of AI and Software Quality. You have a clear perspective on how AI can automate the mundane parts of testing and accelerate the SDLC.
- Extreme Ownership: You take pride in the end-to-end health of the platform. You are proactive in identifying technical debt and are a relentless advocate for engineering excellence.
