RESPONSIBILITIES

• Design and implement scalable solutions using OpenAI APIs and AI agents to enhance system intelligence and automation. Build and maintain validation infrastructure to ensure quality, reliability, and performance of services and platforms. Develop and optimize modern applications on Azure using microservices, containers, and serverless technologies.
• Contributes to the identification of dependencies, and the development of design documents for a product area with little oversight. Helps to identify other teams and technologies that will be leveraged, how they will interact, and when one’s system may provide support to others. Contributes to determining back-end dependencies associated with product, application, service, or platform functionality for product features.
• Creates and implements code for a product, service, or feature, reusing code as applicable. Writes and learns to create code that is extensible and maintainable. Considers diagnosability, reliability, and maintainability with few defects, and understands when the code is ready to be shared and delivered. Applies coding patterns and best practices to write code.
• Creates a clear and articulated plan for testing and assuring quality of solutions, and defines success for outcomes of tests (e.g., unit tests). Adds new tests, removes antiquated tests, and aggregates tests to improve tests in the feature area. Helps to drive efforts for augmenting test cases and ensures that the solution area has good test coverage. Helps to integrate automation features when planning for testing.
• Identifies areas to efforts to integrate instrumentation for gathering telemetry data on system behavior such as performance, reliability, availability, usage, and safety mechanisms. Contributes to sustaining feedback loops from telemetry resulting in subsequent designs. Helps to create outputs of telemetry such as notifications or dashboards.
