Ai / Ml Engineer

Why this role

Chargebee’s GBT AI team builds internal AI agents and workflows that power smarter, faster operations across Finance, HR, Legal, Marketing, RevOps and GTM. We’re looking for an AI Engineer who can think end-to-end—understand the business process, design the right solution (not just an out-of-the-box tool), and ship robust agentic systems that deliver measurable impact.

What you’ll do

• Design, build, and ship AI agents that automate internal workflows (e.G., case triage, knowledge assistants, data reconciliation, summarization, entity extraction, task orchestration).
• Own the full lifecycle : problem framing, data / knowledge mapping, prototype → production, instrumentation, and iteration based on metrics.
• Integrate with the GBT Tech stack using APIs, webhooks, and internal services across our SaaS stack (ticketing / CRM / data warehouse).
• Engineer LLM prompts & tools (function calling, tools / toolkits, retrieval / RAG, multi-step planning) and select the right model for the job.
• Evaluate and harden solutions with offline tests, golden sets, guardrails, and observability;

drive down hallucinations and failure modes.

What you’ll bring (must-haves)

2-6 years of professional software experience , including hands-on delivery of at least one AI agent or workflow in production or a serious pilot.

Nice to have

subscription billing / revenue ops context is a plus.
