Senior AI Developer — Zia & enterprise copilots

Zoho is hiring a Senior Senior AI Developer — Zia & enterprise copilots on the Zia AI platform team (Hybrid · Chennai, India). 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.

**Zoho** builds cloud software used by millions of businesses worldwide — CRM, finance, HR, and collaboration — from its engineering campuses in India.

Senior AI Developer (Chennai hybrid): extend **Zia**, Zoho's cross-product AI assistant, and ship **LLM-powered copilots** embedded in CRM, Desk, and analytics with strict multi-tenant isolation.

You will work with product teams across Chennai and global offices; strong **eval discipline** and **cost-aware** inference matter as much as model quality.
