You are not just writing test cases; you are building the platforms, tools, and guardrails that let product teams ship high-quality code at lightning speed.This role exists at a specific moment. We ship fast, and a growing share of our code is written with AI assistance, by more contributors, more often. That velocity is an advantage we intend to keep. It also means more change hitting the pipeline per day than any manual review process can hold. Your job is to build the automated verification, testability infrastructure, and guardrails that make high-velocity, AI-assisted development safe rather than reckless. You are how we convert "fast because we're reactive" into "fast because the system catches what we miss."You will work closely with engineering leadership, infrastructure teams, and product engineering to shift testing left, eliminate flaky tests, and build quality engineering into our CI/CD pipelines as a first-class concern.Core ResponsibilitiesArchitecture & Tooling InnovationDesign & scale frameworks. Architect, build, and maintain robust, scalable automation frameworks for API, UI, mobile, and backend microservices.Developer experience (DX). Create internal tools, CLI utilities, and mock services that make it frictionless for product engineers, and the AI tools they work alongside, to write and run reliable tests.CI/CD integration. Own the integration of automated testing, linting, security scanning, and performance testing into our deployment pipelines for safe, continuous delivery.Verification for AI-assisted code. Build the test generation, coverage analysis, and pre-merge checks that let the org adopt AI coding tools aggressively without lowering the floor on quality. The faster code is produced, the more the safety net has to be automatic.Quality Strategy & GovernanceShift-left leadership. Champion a culture where quality is a shared responsibility from the first day of design, not an afterthought.Metrics & observability. Establish KPIs for system reliability, test coverage, and pipeline health. Build dashboards that track and reduce flaky tests and deployment bottlenecks, and that distinguish velocity from churn so we can see whether speed reflects good planning or reactive firefighting.Advanced testing. Design infrastructure for advanced methodologies including chaos engineering, load and performance testing, and synthetic data generation.Leadership & InfluenceTechnical mentorship. Guide and mentor engineers across the organization on testing best practices, testability design patterns, clean code, and how to review and harden AI-generated code rather than rubber-stamp it.Cross-functional alignment. Collaborate with Principal and Staff Engineers across Infrastructure and Product to ensure new architectures are inherently testable and observable.Technical ProfileRequired ExpertiseSystems programming. Advanced proficiency in modern backend languages (e.g., Python, Go, Node.js/TypeScript, Java).Automation frameworks. Deep experience with modern testing tools and libraries (e.g., Playwright, Cypress, Appium, PyTest, or native integration test libraries).Cloud & infrastructure.
