Senior AI Engineer

XeroQ is hiring a Senior AI Engineer to be the technical voice in early client conversations. This role exists because the people who understand the technology deeply need to be in the room: you will represent XeroQ's products accurately to prospective clients, understand what those clients actually need, and lead the discussion that connects the two.

This is a remote position. Hours are aligned to US Eastern Time business hours, and the role is available on a part-time or full-time basis.

What you will do

• Build a working knowledge of XeroQ's products and technical approach so you can speak to them accurately in client conversations.
• Research each prospective client's technical environment and use cases before any meeting.
• Plan and structure pre-sales discussions to surface the right questions and frame XeroQ's capabilities against the client's actual problems.
• Lead the technical portion of client meetings, fielding questions and working through objections in real time.
• Collect feedback from each engagement and bring it back internally to sharpen future conversations and inform product direction.

What we look for

• At least five years of professional experience building and deploying machine learning or AI systems, with shipped production work you can point to.
• Demonstrable experience across fine-tuning large language models, training neural networks, building RAG pipelines, and agentic AI systems.
• The ability to write production-quality code in Python and JavaScript.
• Enough comfort with client-facing communication to lead a technical discussion without a script — prior pre-sales or customer-facing experience is a plus, but the baseline is that you can hold the room.

Nice to have

• Experience mentoring other engineers or leading a small technical workstream.
• Prior work in a pre-sales, solutions engineering, or client-facing technical role.
