About this role

What the team is looking for and how this position fits.

Aircall is hiring a Senior AI Engineer — voice & conversation on the Conversation AI team (Hybrid · Montpellier, France). This is a hands-on role in LLM & generative AI—not a generic “AI enthusiast” post.

You will own LLM features, retrieval, agents, and evaluation end to end: problem framing, offline evaluation, safe rollout, and iteration from production signals. Success is measured with clear metrics (quality, latency, cost, or business KPIs)—not slide decks alone.
