ML-QA Engineer

Your tasks
We are looking for a
ML-QA Engineer with strong automation experience testing intelligent/agentic applications
to join our growing engineering team. You will play a critical role in ensuring the quality and reliability of our platform by developing automated test frameworks, writing robust test cases, and collaborating closely with developers, product owners, and DevOps.

The role goes beyond traditional QA: You will be working with A
I-driven, agentic applications that can plan, act, and adapt.
Your job will be to make sure they behave correctly, safely, and predictably under real-world conditions.

Key Responsibilities

• Design, develop, and maintain automated test frameworks and test scripts using Python
• Integrate automated tests into CI/CD pipelines to ensure continuous quality and fast feedback
• Collaborate with developers and product managers to identify, reproduce, and resolve defects early in the lifecycle
• Define and document test plans, strategies, and acceptance criteria for both deterministic and agentic features
• Verify observability and explainability of agent behavior (logs, traces, intermediate actions) to ensure compliance, transparency, and auditability
• Perform scenario-based, exploratory, and chaos testing to validate agent decision-making under uncertainty, failure, and edge conditions
• Test human-in-the-loop workflows, ensuring proper escalation, overrides, and user safety
• Conduct root cause analysis of production issues, including agent misbehavior, and contribute to long-term fixes
• Contribute to the development and enforcement of QA standards and best practices

Your profile
Must-Have Qualifications

• 3+ years of experience in QA Engineering with a focus on test automation for web and distributed systems
• Proficient in Python for developing test scripts, validation tools, and data validation utilities
• Hands-on experience with testing frameworks such as PyTest, Selenium, or Playwright for end-to-end and UI testing.
• Strong understanding of software testing methodologies, including unit, integration, system, and end-to-end testing.
• Familiarity with REST APIs and tools like Postman or Swagger for API testing
• Strong problem solving skills with the ability to think beyond "happy path" testing.
• Understanding of data validation pipeline and data pipeline testing, ensuring integrity and reproducibility across datasets

Nice-to-Have Qualifications

• Experience testing agentic or AI-driven applications (e.g., autonomous decision-making, multi-step workflows)
• Experience with scenario-based or chaos testing frameworks
• Familiarity with observability and monitoring tools (e.g., Datadog, Grafana, AWS CloudWatch) to validate agent behavior
• Experience testing microservices or serverless architectures on AWS
• Familiarity with CI/CD tools like GitHub Actions, Jenkins, or GitLab CI.
• Knowledge of security and guardrail testing (role-based access, safe action validation)
• Experience writing performance and load tests for AI interface endpoints using Locust or k6.

Qualities we Value:

• Systems thinker: You see how parts connect and anticipate failure points
• Exploratory mindset: Comfortable testing for unknown unknowns
• Domain curiosity: Willingness to deeply understand how the agent is supposed to act in the real world
• Ethical awareness: You care about safety, fairness, and unintended consequences in AI systems
• Collaborative: You work closely with engineers, product, and operations to build trust in our platform
