Job Description

Artificial intelligence is transforming how we approach testing and quality assurance. We are building new AI-powered testing capabilities in Visual Studio and the .NET CLI that help developers write better tests, identify edge cases, generate test data, and improve test coverage. Our goal is to make testing faster, smarter, and more effective, integrating seamlessly into the developer workflow.

As a Software Engineer on the .NET AI Testing team, you will be at the forefront of this innovation. You will design and build intelligent agents that suggest test cases based on code, assist with test maintenance as code evolves, and identify potential bugs before they reach production. You will also be responsible for creating the benchmarking frameworks necessary to evaluate the quality and performance of these AI models for coding tasks.

Our technology stack is built on with C# and Azure, leveraging the latest advancements in AI and LLMs.

Our team thrives on the energy of smart, self-driven individuals who approach their work with a positive, can-do attitude and a dedication to craftsmanship in code. We see AI not just as a tool, but as a fundamental shift in how software is created, and we are looking for engineers who are equally captivated by this potential. If you are already experimenting with the latest in LLM technology and are eager to chart new paths in developer productivity and automated testing, you’ll fit right in.

Responsibilities

• Research and experiment with emerging AI technologies to identify new opportunities for developer productivity.
• Design and implement AI-powered tools for automated unit test generation, code analysis, and intelligent test maintenance.
• Develop and maintain benchmarking frameworks to evaluate the performance and quality of AI models for .NET coding tasks.
• Work closely with .NET product teams to integrate AI capabilities directly into the developer workflow (Visual Studio, VS Code, CLI).
• Mentor junior engineers, conduct code reviews, and contribute to a culture of technical excellence and continuous learning.
• Write clean, maintainable, and efficient code in C#, ensuring high reliability and performance.

Qualifications

• BS in Computer Science, EE, Computer Engineering or equivalent experience.
• Experience with AI/ML concepts, specifically Large Language Models (LLMs) and prompt engineering.
• Demonstrated passion for developer tools and improving developer productivity.
• Experience working with one or more of the following languages: C#, Java, Python or similar programming languages.

• Excellent teamwork and communication skills.
• Proficiency in the .NET ecosystem and hands-on experience with testing frameworks and code coverage tools will be a significant advantage.

This position will be open for a minimum of 5 days, with applications accepted on an ongoing basis until the position is filled.
