About the Role

Are you passionate about software quality and innovation? We’re looking for a talented Software Development Engineer in Test (SDET) to join our growing engineering team. In this role, you’ll play a critical part in ensuring the quality and reliability of our products—leveraging cutting-edge AI tools to automate and enhance testing processes, and supporting the delivery of next-generation agentic products to market.

You’ll work with cross-functional teams to design and implement scalable, high-quality automated tests, while championing best practices and promoting a culture of excellence.

What You’ll Do

• Leverage AI tools (e.g., Copilot) to assist in the creation of test cases, unit tests, UI tests, and performance tests—accelerating automation and increasing coverage.
• Develop comprehensive testing strategies for AI-based products, including testing agent responses, evaluating model reliability, validating data inputs and outputs, and ensuring overall system performance.
• Design, build, and maintain automated test frameworks using C#, Python, and/or TypeScript.
• Implement and maintain automated testing frameworks and tools.
• Develop and execute contract testing (e.g., PACT testing) to ensure seamless integration with external APIs and services.
• Conduct manual testing where required, including functional, exploratory, regression, integration, and end-to-end testing, to identify issues that may not be captured through automated testing.
• Collaborate closely with developers to understand requirements and identify potential issues early in the development lifecycle.
• Conduct thorough code reviews and provide constructive feedback to peers.
• Participate in all phases of the software development lifecycle—from planning and design to release and maintenance.
• Promote a culture of quality by advocating for best practices and continuous improvement throughout the development process.

What You Bring

• Proven experience using AI tools for test creation and execution, improving efficiency and accuracy in test automation.
• Experience developing QA strategies for AI-based products, including evaluating agent responses and ensuring model fairness and scalability.
• Strong hands-on experience with both manual and automated software testing, with the ability to determine the appropriate testing approach based on the feature, risk, and requirements.
• Strong programming skills in C#, Python, and TypeScript.
• Hands-on experience with automated testing frameworks and tools.
• Experience with contract testing and tools like PACT.
• Excellent analytical and problem-solving skills.
• Strong communication and collaboration skills, with the ability to work effectively in cross-functional teams.

Bonus Points

• Experience with cloud platforms (e.g., AWS, Azure, GCP).
• Experience with performance and security testing.
• Familiarity with Agile development methodologies.

Who You Are

• Experienced: Proven track record in software development and testing.
• Independent: Self-motivated and capable of working with minimal supervision.
