About The Position

Senior Software Development Engineers in Test operate as technical leaders within a team, owning validation strategy and system quality for complex systems. A workstream is a product-aligned engineering organization responsible for delivering a cohesive set of customer and business capabilities. Within a workstream, domains are composed of multiple value lanes (teams), each with its own charter and outcomes. Senior Software Development Engineers in Test operate within a value lane, leading validation efforts for complex systems and workflows while influencing practices that improve system quality across the broader domain. This role is responsible for designing and driving comprehensive validation strategies for team-owned systems, ensuring systems behave correctly and reliably under real-world conditions, and elevating testing practices within the team. You will collaborate closely with software engineers, product managers, and product designers to ensure complex workflows are validated effectively and meet high standards for correctness, performance, and resilience. Senior Software Development Engineers in Test demonstrate strong ownership and technical leadership within the team, with a deep understanding of how system behavior, reliability, and performance impact customer experience and business outcomes within a workstream.
