Senior Software Development Engineer in Test - AI

Anaplan; United States; On-site; USD 120,000 - 180,000; Full time

Job summary

Anaplan is seeking a Senior SDET for AI to lead testing for GenAI/Agentic systems. You will design evaluation frameworks, build end-to-end automated suites in Python, and create prompt testing systems to detect changes in model behavior.

You will establish evaluation criteria across accuracy, safety, and latency, and drive QA best practices across the org. You will develop internal tools, monitor production AI features in real time, and partner with software engineers to validate GenAI

Qualifications

• Deep understanding of GenAI technologies including LLMs, prompt engineering, and AI application patterns.
• Strong hands-on Python coding experience.
• Expert experience with test automation frameworks and scripting (Python, JavaScript, Selenium, Pytest).
• Strong background of software testing methodologies (functional, integration, regression, performance, security testing).
• Proven ability to design test cases and evaluation criteria for non-deterministic systems.
• Strong analytical and problem-solving skills with attention to detail.
• Experience with API testing tools (Postman, REST Assured) and backend testing.
• Strong experience with CI/CD pipelines and automated testing integration.

Responsibilities

• Design and architect comprehensive test plans, evaluation frameworks, and quality metrics designed specifically for LLM-powered applications and agentic workflows.
• Develop robust, end-to-end automated test suites in Python across evaluations, API checks, UI checks, and performance tests.
• Create automated prompt testing systems and regression suites to proactively detect unintended changes in model behavior.
• Establish multi-dimensional evaluation criteria to measure and track GenAI quality across accuracy, relevance, safety, consistency, and latency.
• Perform adversarial testing (red-teaming) to identify and mitigate model hallucinations, biases, or security vulnerabilities.
• Develop internal tools and testing frameworks that enable software engineering teams to seamlessly validate their own GenAI implementations.
• Deploy real-time monitoring and alerting systems to quickly detect and flag quality degradation of AI features in production.
• Own the overall quality and testing strategy for your workstream, maintaining high-fidelity test datasets ("golden examples") and defining QA best practices.
