Senior AI Engineer: Production LLM & Automation (Remote)

Ruby Labs Ltd is seeking a Senior AI Engineer to own and scale the AI layer of a core D2C subscription product. You’ll own production LLM features and the browser automation built around them end to end — prompts, outputs, evaluation, and observability. Work in a modern TypeScript stack (Next.js, Cloudflare Workers, Playwright) and drive model selection, cost efficiency, and reliability. This is a high-impact role with data‑driven decisions and shipped automation as frozen, versioned workers.
