Senior Software Engineer, Developer Tools

Every day tens of millions of people come to Roblox to explore create play learn and connect with friends in 3D immersive digital experiences all created by our global community of developers and creators.

At Roblox were building the tools and platform that empower our community to bring any experience that they can imagine to life. Our vision is to reimagine the way people come together from anywhere in the world and on any device. Were on a mission to connect a billion people with optimism and civility and looking for amazing talent to help us get there.

A career at Roblox means youll be working to shape the future of human interaction solving unique technical challenges at scale and helping to create safer more civil shared experiences for everyone.

The App Test team builds the test automation platform that enables Roblox engineers to deliver reliable high-quality experiences across the Roblox Universal App. Our systems span test frameworks execution and orchestration device-farm infrastructure debugging tools dashboards and the supporting infra that power end-to-end testing across mobile desktop console and VR.

As a Senior Software Engineer on the App Test team you will design build and scale tools and services that power the test automation lifecycle. You will work on foundational systems that enable engineers to author select execute debug maintain and triage tests efficiently while helping evolve our platform toward an AI-native testing experience.

You will have the opportunity to solve complex engineering problems across distributed systems cross-platform automation developer tooling and AI orchestration. Your work will help teams identify regressions earlier improve release confidence and deliver software faster without compromising quality.

You will:

• Build and scale test automation infrastructure: Design implement and evolve the frameworks runners orchestration services device-farm integrations and supporting infrastructure that power reliable end-to-end testing across Robloxs supported platforms
• Advance the AI-native test lifecycle: Develop intelligent tooling that improves test authoring selection execution maintenance and failure triage using AI to reduce manual effort and make testing more accessible and effective
• Develop test orchestration and intelligence: Build systems that connect test planning test selection execution and failure analysis enabling more efficient use of test infrastructure and faster feedback to engineers
• Improve test reliability and debugging: Build tools and services that improve test stability observability failure diagnosis and maintenance across a large and evolving test ecosystem
• Shift quality earlier in the development lifecycle: Integrate automated quality checks and actionable test feedback into development and CI/CD workflows to help teams identify and resolve issues earlier
• Drive projects end to end: Take ownership of technical initiatives from problem definition design and implementation through production deployment adoption measurement and continuous improvement
• Collaborate across engineering: Partner with application platform QA infrastructure and developer productivity teams to develop scalable solutions that address the needs of engineers across Roblox

You have:

• Software engineering experience: Experience designing building testing and operating production software with a track record of solving complex engineering problems in large codebases
• Programming fundamentals: Strong programming skills in C Python Go or another modern programming language with an emphasis on writing maintainable reliable and well-tested code
• Automation and infrastructure experience: Experience building test automation frameworks developer tools distributed systems CI/CD infrastructure or other engineering platforms
• Systems and architecture: Experience designing and evolving services or frameworks with an understanding of scalability reliability observability and operational excellence
• Cross-platform engineering: Experience developing or supporting systems across multiple platforms or environments such as Windows macOS Linux Android or iOS
• Ownership and collaboration: Ability to take ownership of projects work effectively across teams communicate technical decisions clearly and deliver solutions that improve the experience of engineers who use your tools

• Experience with cross-platform test automation frameworks such as Appium Selenium or comparable tools including mobile desktop or game testing
• Experience building CI/CD release engineering developer productivity or internal platform systems
• Experience applying LLMs agents or other AI techniques to developer tools including test authoring intelligent test selection test maintenance failure analysis or automated debugging
• Experience working with large-scale software development workflows and integrating automated quality checks into the development lifecycle
