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

• 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

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
