Senior AI Engineer

Help to build AI agents that handle real customer interactions for field sales teams - across chat and voice. This startup already has 2,000 B2B customers, including enterprises with 10,000+ employees.

We’re hiring a Senior AI Engineer to own agent quality.

What you’ll own

• Build and improve LLM agents in Python
• Model selection, prompting and context engineering
• Evaluation, benchmarking and agent harnesses
• Turn real conversations into test cases
• Find failure modes and ship measurable improvements

This is about orchestrating and evaluating models - not training them.

What we're looking for

• Strong Python
• Production experience building LLM / AI agents
• Experience with evals, benchmarking or AI quality
• Strong technical ownership and product judgement
• A track record of shipping and improving AI systems with data

Experience with voice agents, realtime AI or multilingual agents is a plus.

Why this role?

You’ll own a mission-critical part of the product from day one, with significant autonomy and direct impact on how the agent performs in production.
