AI Agent Developer & Tester

Responsible for implementing and testing Lang Graph-based AI agent workflows within the APEX platform, including node-level unit testing, graph-level integration testing, regression suite ownership, and production observability. Also owns E2E UI test coverage via Playwright across all three APEX portals and manages GCP infrastructure supporting the agent layer.

• Agent unit testing - every node tested in isolation with mocked state before it ships
• Agent graph testing - full end-to-end graph runs with controlled inputs
• LLM mocking strategies – unit test, mock, fake model stubs, or framework-level mocking; non-determinism must be controlled
• Flaky test management - controlled seeds, mocked outputs, or threshold-based assertions for non-deterministic agent behavior
• Regression test authorship - every bug fixed gets a regression test before the fix is considered done
• Playwright E2E testing - responsible for test coverage, not just test authorship; actively tracks and closes flow gaps
• Structured output / JSON schema validation
• Application Development and Support Experience in cloud (GCP is preferred but any cloud is fine)

• Lang Smith / RAGAS
• Financial services / regulated industry
