QA Engineer For Voice Agent

QA Engineer for AI Voice Agent, available TODAY (healthcare, Node/Python) Description Urgent. I need someone who can start within hours, not next week. We run an AI voice agent that books real appointments for a psychiatry practice. We have around 1,200 automated tests and a behavioral simulation suite, and defects keep shipping anyway, because the tests pass while the thing they cover is broken. I need help triaging that, starting today. Today: get oriented and start going through the test suite with me. The first deliverable is simple: which cases do you not trust, and why. Tomorrow, 1:30 PM Pacific (4:30 PM Eastern / 20:30 UTC): on a client call with me. You need: - Strong Python and JavaScript/Node. You will be reading and rewriting test code. - Experience testing non-deterministic systems. The system under test is a language model, so the same input gives different output and "it passed once" is not a result. - API and log-based verification, plus Playwright for the web surfaces. - Genuinely available today and tomorrow at 1:30 PM Pacific. This is the hard requirement. If you cannot make that call, please do not apply, however good you are. Ongoing work after this week if it goes well. In your proposal, answer these three. Skip the cover letter. 1. Can you start today, and be on a call tomorrow at 1:30 PM Pacific? Yes or no. 2. Tell me about a test you found that was passing while the thing it tested was broken. How did you find it? 3. Are you able to make test calls to the voice agent in addition to programming? 4. How would you approach solving this problem?
