AI Engineer

Job Description

Senior AI Engineer sought to join a small, exceptionally fast-moving engineering team building an AI-native consumer platform. There is a salary up to $500K + equity on offer here, so we are only interesting in exceptional candidates with a genuine production AI development backgrund.

Want to build AI agents that do more than just answer questions? Backed by a major global technology group, this is an opportunity to own production AI systems from architecture through to deployment. As a Senior AI Engineer, you'll build the conversational intelligence behind a product that understands user preferences, retrieves relevant information and takes real-world actions. You'll own agent orchestration, tool calling, conversational memory and multi-step reasoning.

We're looking for a Senior AI Engineer with:

• 4+ years in backend or full-stack engineering with hands-on LLM product development.
• Experience shipping LLM-powered ranking, retrieval or recommendation systems into production.
• A background building consumer-facing (B2C) products is essential - not just internal tools or enterprise applications.
• Strong applied AI experience across prompting, embeddings, RAG, agent memory and personalisation.
• Practical experience building evaluation frameworks and debugging ranking or retrieval failures in production.
• Experience with TypeScript or Python and AI-assisted development workflows.
• The ability to move quickly, make architectural decisions and take ownership without layers of management.

This Senior AI Engineer position suits someone from either a high-growth startup or product-led technology company who enjoys building and shipping rather than researching models.

You'll join a lean engineering team with substantial financial backing, genuine product ownership and competitive equity. There is a salary of $350k-$500k + equity available and the role is full time on site in NYC.
