Software Development Engineer in Test - SDET

This position is listed on behalf of a partner company, who manages all applications and next steps. Our partner is looking for a Software Development Engineer in Test - SDET based in India. This role offers the opportunity to take ownership of critical test infrastructure and help shape quality engineering practices across a modern, fast-moving technology environment. You will design scalable automation frameworks and testing strategies for complex product capabilities while influencing architectural decisions around test design. The position combines advanced software engineering, test automation, cloud infrastructure, and CI/CD optimization. You will work closely with engineering teams to shift quality earlier in the development lifecycle and build reliable, maintainable testing processes. Beyond hands-on technical work, you will mentor junior SDET engineers and contribute to technical reviews and engineering standards. This is a high-impact opportunity for an experienced SDET who enjoys solving complex automation challenges and improving quality at scale. Accountabilities Architect, build, and maintain scalable test frameworks and infrastructure, making informed architectural decisions around test design patterns, abstractions, and maintainability.Develop comprehensive testing strategies for complex features and platform capabilities, integrating quality practices earlier into the software development lifecycle.Collaborate closely with engineering and cross-functional teams to identify quality risks, improve test coverage, and establish effective automation practices.Refactor, optimize, and maintain existing test suites to improve reliability, maintainability, scalability, and execution performance.Diagnose and improve CI/CD pipelines, reducing test execution times and resolving automation or pipeline-related bottlenecks.Build and manage AWS-based test environments, including environment configuration, monitoring, troubleshooting, and debugging.Develop custom testing tools, automation utilities, and reporting solutions that provide actionable quality insights.Design and implement API testing and orchestration across REST and GraphQL services, including integrations with UI-based workflows.Apply scalable object-oriented test architecture and reusable abstractions rather than relying on linear or repetitive test scripts.Produce and maintain advanced test reporting using solutions such as Allure, Playwright HTML reports, and custom reporting frameworks.Conduct technical code reviews and contribute to engineering standards, best practices, and architectural decisions.Mentor SDET I engineers, helping them strengthen their automation, software design, and testing capabilities.Continuously identify opportunities to improve test infrastructure, developer productivity, automation reliability, and overall engineering quality. Requirements Extensive hands-on experience with Playwright, including deep knowledge of its fixtures architecture and scalable test automation practices.Strong experience designing object-oriented test frameworks using layered patterns such as Page Object Model (POM), Page Component Object Model (PCOM), and other reusable abstractions.Proven experience with API testing and orchestration using REST and GraphQL, particularly when integrated with UI workflows.Advanced TypeScript expertise, including generics, decorators, advanced typing patterns, type inference, and complex asynchronous programming.Strong understanding of concurrency, asynchronous execution, race-condition prevention, and reliable automation in distributed or parallel environments.Solid software design knowledge, including domain-driven design and design patterns such as Factory, Builder, Facade, and Composite.Hands-on AWS experience, including EC2 configuration, CloudWatch log analysis, cloud environment debugging, and management of test infrastructure.Strong Docker experience covering containerization, docker-compose, image management, and conta
