Senior SDET: Scalable Test Automation & Reliability

Meta; Menlo Park (CA); On-site; USD 146,000 - 203,000; Full time

Job summary

Meta is seeking a Software Development Engineer in Test to advance quality and reliability for large-scale software systems. You will design scalable test infrastructure, automation frameworks, and validation pipelines to help engineering teams ship high-quality software with confidence.

You will partner with product and infrastructure engineers to define testability, identify quality gaps, and scale testing strategies across complex, distributed environments.

Qualifications

• Experience designing and building automated test frameworks and infrastructure for large-scale or distributed software systems
• 6+ years of experience in software development engineering in test, test automation, or quality engineering roles
• Bachelor's degree in Computer Science, Computer Engineering, relevant technical field, or equivalent practical experience
• Experience with performance, load, or reliability testing methodologies and tooling
• Experience identifying root causes of test failures and production defects through systematic debugging and analysis
• Experience influencing engineering decisions through written technical proposals and cross-functional stakeholder alignment

Responsibilities

• Design and implement scalable automated test frameworks, test harnesses, and validation infrastructure for large-scale distributed systems
• Define and drive end-to-end testing strategies including unit, integration, system, regression, and performance testing across multiple product areas
• Collaborate with product and infrastructure engineers to embed testability requirements early in the software design and development lifecycle
• Develop tooling and pipelines to improve test coverage, test execution speed, and signal quality across CI/CD workflows
• Identify systemic quality gaps through root cause analysis of failures, flaky tests, and production incidents, and drive resolution across teams
• Establish and evangelize testing best practices, coding standards, and quality engineering patterns for the broader engineering organization
• Lead technical design reviews for test infrastructure components, providing guidance to peers on architecture and implementation tradeoffs
• Build observability and reporting systems to surface test health metrics, coverage trends, and reliability signals to engineering leadership
• Partner with cross-functional teams to define quality gates and release criteria that balance velocity with production reliability
