Senior Software Engineer in Test

Responsibilities The Database QA team is where distributed systems theory meets real-world chaos We own the end-to-end quality of YugabyteDB, rigorously validating everything from core storage and language layers (YSQL/YCQL) to high-impact features like Change Data Capture By blending performance engineering with system-level stress testing, we ensure our database thrives in the most unpredictable production environments. We are the champions of correctness in a distributed world In this role, you will build and break distributed systems at scale As an SDET at Yugabyte, you will design sophisticated automation and chaos-testing frameworks that simulate real-world disasters to validate our database’s core promises You’ll dive deep into cross-feature integration and security, collaborating with development teams to influence the product’s evolution Architect, develop and maintain test automation frameworks Design and execute comprehensive test suites focusing on the “hard problems” of distributed databases: stress, resiliency, scalability, and performance Design and orchestrate distributed systems tests that simulate real-world failure modes Own the end-to-end quality of major features, from initial design review and test planning to production-ready automation Modernize existing test footprints by identifying opportunities for redesign, improved efficiency, and higher stability in CI/CD pipelines Uncover deep-seated bugs such as data corruption and consistency violations Deep-dive into the codebase to understand technical dependencies and execution paths, ensuring tests target the most critical logic Scale our test infrastructure, ensuring that the built tests scale with our growing feature set Define and inspire changes to our product with our development engineering team based on feedback from tests and customer issues Act as a technical lead for junior engineers and serve as an internal advocate for the customer experience Develop and contribute to internal and external knowledge bases. Be a champion for our customers Go above and beyond to ensure customers are getting the most out of their investment in the Yugabyte database Benefits Health Insurance Company Stock Options Retirement Plans Home Office Set-Up Reimbursement Professional Development Reimbursement Quarterly Wellness Days Off Unlimited PTO Childcare benefits Performance bonuses Qualifications Are you obsessed with finding the ‘impossible’ bug? We’re looking for a technical leader who can transform complex customer scenarios into rigorous stress tests, ensuring YugabyteDB remains the gold standard for distributed SQL. Strong foundation in Distributed Systems: Deep understanding of distributed architecture, including consistency models (linearizability, serializability), the CAP theorem, and consensus protocols (Raft) A proven track record of identifying complex bugs, specifically data corruption and consistency issues Ability to leverage generative AI and LLM-based coding assistants to accelerate the authoring, refactoring, and optimization of complex test suites Proficient in Data Structures and Concurrent Programming. Must be comfortable reading and navigating the complex C++ codebase to identify potential failure points 5–8 years of experience in Software Development in Test (SDET) or Systems Engineering, with a BS/MS in Computer Science or a related field Sound understanding of JDBC APIs and database connectivity Hands-on experience with Linux, shell scripting, Git, and architecting scalable CI/CD pipelines Database Internals Expertise: Highly desirable knowledge of query processing, transactions (ACID), recovery logs, and concurrent B-tree access Working knowledge of Python, Java programming languages and advanced SQLExceptional troubleshooting skills with a “break-it” mindset; ability to trace issues from high-level test failures down to the code level for both internal and customer-reported bugs #J-18808-Ljbffr Yugabyte
