Qualifications

• Bachelor's or Master's degree in Computer Science, Engineering, or a related field, or equivalent relevant experience.
• Typically 6–8 years of software testing or engineering experience, including at least 3 years focused on backend APIs and service-based architectures.
• Substantial hands-on experience developing test automation frameworks and integrating them into automated delivery pipelines.
• Strong proficiency in a general-purpose programming language, with the ability to design, review, and debug maintainable test code.
• Deep understanding of API testing, microservice interactions, service contracts, and distributed application behavior.
• Advanced automation design skills, including test lifecycle management, parameterized execution, mocking, shared utilities, and parallel execution.
• Practical experience testing and troubleshooting public-cloud applications, including identity and permissions, networking, compute, storage, and messaging dependencies.

• Strong database querying skills and the ability to trace data and failures across multiple services.
• Ability to turn incomplete requirements into meaningful tests and communicate technical findings clearly.

Responsibilities

• Design, build, test, and maintain shared automation frameworks, internal services, and developer tools that serve multiple QA and engineering teams.
• Own test strategy and execution for backend APIs, microservices, and end-to-end business workflows, balancing component, contract, integration, and system-level coverage.
• Design and extend code-based automation frameworks with reusable setup and cleanup, data-driven scenarios, dependency isolation, and clear failure reporting.
• Validate business rules, API contracts, data persistence, authorization, error handling, and compatibility across services.
• Test asynchronous processing and distributed-system failure conditions, including retries, duplicate events, partial failures, and delayed consistency.
• Establish reliable automated checks in continuous integration and delivery pipelines, improving feedback speed and reducing flaky tests.
• Validate cloud-hosted services and deployment configurations; troubleshoot failures using application logs, service telemetry, and infrastructure evidence.
• Assess performance and resilience risks, design targeted tests, and collaborate with engineers to address identified weaknesses.
• Review requirements and architecture, communicate quality risks, and mentor engineers while independently driving complex testing work.
• Perform other related duties as assigned.
