About the Role:

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.

Responsibilities:

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

What Success Looks Like:

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
