Save Report this job Change Software ForeverMost engineering roles build software nobody fully trusts. This one builds the trust layer itself. AI is making engineers dramatically more productive. The problem is nobody fully trusts what AI ships.Why this matters nowAI is rewriting how software gets built. But shipping still breaks on testing.
