Improve test case generation, defect detection, flaky test analysis, regression testing, and test coverage optimization.
Work with product, engineering, and cross-functional teams to review requirements and define test strategies.
Build test plans, design and execute test cases, and report quality status, risks, bugs, and results.
Perform functional, performance, fault-injection, reliability, and regression testing for AI apps and agents and end-to-end agentic workflows.
Automate test cases and contribute to scalable test frameworks and agent test harnesses.
Manage the bug lifecycle, reproduce customer issues, and verify fixes.

MS or PhD in Computer Science, Engineering, or a related field (or equivalent experience).
8+ years of QA, test automation, or software testing experience.
Hands-on experience developing, testing, and maintaining AI agents or their underlying components, such as models, agent harnesses, and inference runtimes.
Practical experience configuring, running, and debugging open-source models using at least one inference runtime or framework.
Strong QA fundamentals, test strategy, test planning, and failure analysis skills.
Proficiency with Unix/Linux, Python programming, and shell scripting.
Experience with Kubernetes, containers, CI/CD pipelines, and cloud-native systems.
Experience testing observability tools such as Prometheus, Grafana, ELK Stack, Datadog, or similar platforms.
Experience with large-scale failure testing, using tools such as KWOK, Chaos Monkey, or similar frameworks.
Strong communication, problem-solving skills, and curiosity for complex technology

Ways to stand out from the crowd:

Used AI to reduce testing time, improve defect detection, or increase test coverage.
Built AI-driven solutions that streamlined QA workflows or reduced manual effort.
Experience with NVIDIA GPU hardware or GPU-accelerated software.

Skills and AI tools this role asks for

AI agents

Questions you could be asked

How do you decide when an AI agent can act on its own versus asking for approval first?
How would you decide a model or AI system is ready to ship?
Tell me about a time a model underperformed in production. How did you find out, and what did you change?

Adapt your resume

List these exact terms on your resume: AI agents. An applicant tracking system matches the wording, not the idea.
Attach one line of real, concrete experience to at least one of them. A tool named with nothing behind it rarely survives a human read.
Lead with what you built, trained or shipped. This role is judged on the AI system itself, not the tools around it.
