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.

• Designs and implements comprehensive automated validation strategies for team-owned systems, covering APIs, services, and critical workflows
• Writes clean, scalable, and maintainable test automation code and improves existing frameworks where needed
• Ensures automated validation is fully integrated into CI/CD pipelines to provide fast, reliable feedback
• Owns validation for complex features and workflows, including edge cases, failure scenarios, and performance considerations
• Ensures systems behave predictably under real-world conditions, including peak load and degraded scenarios
• Leads debugging and root cause analysis of complex defects and system issues
• Uses logs, metrics, and traces to deeply understand system behavior and identify reliability gaps
• Drives improvements in system testability by influencing design decisions and collaborating closely with software engineers
• Defines validation strategies that balance coverage, execution speed, and maintainability
• Partners with product managers and product designers to ensure validation aligns with customer workflows and product requirements
• Ensures systems meet expectations for correctness, reliability, performance, and user experience prior to release
• Improves testing practices, automation frameworks, and validation workflows within the team
• Mentors engineers on testing strategies, debugging approaches, and system validation
• Leverages AI-assisted engineering tools to improve validation efficiency, defect detection, and system understanding
• Continuously improves system knowledge, validation approaches, and engineering practices

• Owns and delivers comprehensive validation for team-owned systems and critical workflows
• Author and maintain test plans, test cases, and automated suites (UI, API, regression).
• Improves system reliability by identifying and addressing defects before they reach production
• Demonstrates strong technical leadership within the team, particularly in validation and system quality
• Elevates testing practices, automation quality, and validation strategies within the team
• Reduces defects, improves system stability, and increases confidence in releases
• Collaborates effectively with engineers and product partners to ensure high-quality outcomes
• Proactively identify potential reliability and security issues prior to release
• Demonstrates a deep understanding of how system behavior impacts customer experience and business outcomes

Required:

• Deep experience with automated testing (unit, integration, API, and end-to-end testing)
• Experience designing and maintaining automated testing frameworks (e.g.,…
