About the Team
The Testing Tools & Infrastructure team within the Consumer Lifecycle Experiences Platform is crucial to our Commerce organization. It serves Commerce Experiences by making pre-production testing faster and more reliable. It achieves this by providing centralized platforms for distributed test execution, customer test data creation tools, flaky test analytics and management, and GenAI-powered tooling that enable fast, trustworthy pre-production feedback.
We are part of a global, diverse organization that includes people of all genders, sexual orientations, upbringings, nationalities, ages, and socioeconomic & educational backgrounds. We encourage anyone passionate about developer platforms and testing infrastructure to apply.
About the role
We are looking for an experienced Senior Software Engineer to build developer-facing infrastructure and tooling that scales to millions of test runs per month. You will design and operate language-agnostic systems - spanning distributed execution infrastructure, telemetry and GenAI-powered developer tooling that make pre-production feedback testing fast and trustworthy.
Our ideal candidate is passionate about developer productivity and thrives on the satisfaction of empowering Commerce Engineering engineers worldwide to quickly and comprehensively test their software. They are excited to leverage their experience building and maintaining automated testing and resilience platforms to provide long-term benefits.
Key responsibilities
Primary stack: Java, JavaScript/TypeScript, Python, GraphQL, GitHub Actions. You’ll work alongside test frameworks (JEST, Mocha, Playwright) through platform integration work - but you won’t author or maintain test suites yourself
Implement and manage software solutions that provide accurate and efficient analysis of test runs
Create and maintain tools for framework-agnostic analysis of distributed tracing tools for test runs
Stay informed about industry trends and emerging technologies - particularly GenAI applied to developer platforms - to ensure Commerce Engineering remains at the forefront of testing infrastructure
Develop and integrate software solutions that provide high-quality synthetic test data generation
Integrate internal and vendor-provided distributed test execution infrastructure into engineering workflows with a focus on reliability and ease of use
Develop the tools, frameworks and infrastructure that product engineers use to exercise frontend and backend systems - distributed tests execution, mocking, synthetic data, contract verification and performance harness
Design and operate the systems to automatically detect, quarantine, and self-heal flaky tests - turning noise into an actionable signal for engineers, with GenAI-assisted diagnosis
Correlate test coverage data with code changes, runtime execution, and trace data for comprehensive reporting
Maintain a strong focus on scalability, usability, and reliability in platform design to support a growing organization of stunning engineers
Define testing strategies in partnership with cross-functional teams - producing documentation on frameworks and troubleshooting patterns that internal teams rely on
Must Haves
A stunning software engineer with experience working on developer platform, platform services, or productivity-tooling teams - energized by unblocking other engineers and amplifying their throughput
A meticulous software designer who researches and documents technical tradeoffs clearly and concisely
Deep understanding of distributed systems, service design, and automation platforms (CI/CD, test orchestration)
Hands-on GenAI fluency - daily use in your engineering workflow, plus experience shipping LLM-powered systems, ideally for developer users
Ability to independently drive organization-wide solutions and manage complex technical projects from conception to completion
Ability to synthesize complex technical information and communicate it effectively to both technical and non-technical stakeholders
Experience establishing strong testing culture, including proficiency with popular test frameworks, code coverage tools, continuous integration systems, and post-deployment verification methods (healthy contempt for flaky tests is a plus)
Nice To Haves
You have shipped and maintained Java, JavaScript or Python code in production
You have designed and implemented metrics data pipelines
Experience running and operating continuous integration systems like GitHub Actions, Jenkins, CircleCI and others
Guide the roadmaps of Infrastructure teams according to the specific needs and requirements of product-focused team members
You have generated and analyzed traces like Distributed tracing/ Zipkin/ Honeycomb/ Datadog/ Splunk/ Elastic Search APM
You have implemented advanced log, metric, or error stack trace analysis
You strive to elevate the knowledge and skills of yourself and others in a way that fosters an inclusive, collaborative environment. Deeply enjoy working on solutions that empower other engineers in their work
Thrive in an ambiguous environment and can self-manage and self-prioritize your time, energy, and resources
Understand that engineering is a team sport and actively farm for feedback and dissent
Experience working with a globally distributed team
