The Senior Full Stack AI Engineer is a senior engineer who takes AI features from prototype to production end to end — owning the full stack: frontend, backend, data, deployment, and the AI layer itself including quality, evals, observability, and integration into adjacent products. This is a senior IC role with high autonomy. You will own AI initiatives, scope and de-risk new AI capabilities through prototypes, and then partner with product and other technical teams to integrate matured AI features into our products with the right safeguards. The role demands strong AI engineering fundamentals (LLMs, agents, RAG, evals, voice/multi-modal, classical ML where it fits), strong full-stack development skills, and fluency with modern AI assisted software development tools e.g. Claude Code, MCP, custom skills, agent orchestration — as the default way you work, not a side experiment.
