About the Role
We are seeking a passionate and skilled Software Development Engineer in Test (SDET) to join the Rufus Quality Engineering team at Amazon. Rufus is Amazon's conversational AI shopping assistant, and as an SDET on this team, you will play a critical role in building scalable test automation frameworks, enabling Continuous Deployment (Full CD), and driving quality excellence across Rufus services. This role is ideal for engineers who thrive at the intersection of software development and quality engineering—building tools, frameworks, and intelligent systems that empower developers to ship high-quality features at speed.

Key responsibilities include:
- Designing, building, and maintaining scalable test automation frameworks for Rufus backend services, frontend applications, and GenAI model validation.
- Developing and maintaining internal testing tools that enable SDEs to self-serve test execution and quality validation.
- Creating testing strategies and tooling for validating generative AI outputs, including prompt engineering evaluation, model response quality benchmarking, and regression testing.
- Contributing to the development of agentic AI systems for autonomous test generation, intelligent failure analysis, and predictive quality modeling.
- Collaborating closely with feature teams to embed quality earlier in the development lifecycle, reducing production escapes through proactive testing and quality gates.

Experience
- Programming experience with at least one modern language such as Java, C++, or C# including object-oriented design.
- Experience building test automation frameworks and tools.

About you
- Passionate about software development and quality engineering.
- Strong problem-solving skills and ability to work collaboratively in a fast-paced environment.
- Interest in AI and generative AI quality validation is a plus.

Qualifications
- Knowledge of overall system architecture, scalability, reliability, and performance in a database environment is preferred.
- Experience with security in service-oriented architectures and web services is desirable.
- Commitment to diversity, inclusion, and equal opportunity employment.
