AI Platform Engineer

About the role

We're hiring a Senior-Staff AI Platform Engineer to be the first dedicated engineering hire embedded inside one of our clients a US-based, early-stage AI startup building AI for deal and contract workflows (starting in real estate and expanding toward a broader contracts/HR platform). The product is AI-heavy: a chat-first interface layered over document review, deal timelines, and next-step recommendations, powered by a mix of LLMs and classic/deterministic ML. This is not a research or pure model-training seat. We're looking for a builder with high agency who ships production software and operates LLM/ML systems in the real world. You'll build day-to-day with AI coding tooling (Claude Code, Codex CLI) that's how the team works and you'll own the reliability, observability, and quality of AI features in production.
