AI Engineer (Full-Stack) — Imitate Labs
Location: Chennai (Thiruvanmiyur), In office

Reports to: Founder & CEO (David)

Works alongside: Product Engineer (Sarathkumar)

Joining: September / October 2026
ABOUT THE ROLE
Imitate Labs is building Aurra Sales Agent, an AI-powered voice calling platform helping B2B businesses across India automate customer conversations. We serve Real Estate, Insurance, Automotive, Healthcare, EdTech, and NBFC clients.
We're looking for an AI Engineer whose primary focus is the AI layer itself — choosing and evaluating the models we run on, improving how our voice agents converse, bringing down inference and infrastructure cost, and building the intelligence products we sell to clients.
This is a builder's role in a small team, so the work doesn't stop at a recommendation. You'll write the Python services that power our voice agents and AI pipelines, build and extend the Node.js backend and Next.js interfaces around them, and deploy and operate what you ship on our cloud infrastructure.
KEY RESPONSIBILITIES
Core Focus — AI, Models & Intelligence
1.



Model Evaluation & Cost Optimization
- Evaluate and compare LLM, Speech-to-Text, Text-to-Speech, and voice agent options to bring down inference and infrastructure cost without hurting conversation quality.
- Benchmark providers and model tiers on latency, accuracy, and cost-per-minute, and make a clear call on what we should be running.
- Own our cost-per-call and cost-per-minute numbers — token economics, prompt and context budgeting, caching, and understanding where the money actually goes.
- Assess self-hosted open-weight models against hosted APIs where the economics make sense.
- Build quick prototypes, test promising options against real call data, and take the winning one to production.
- Keep clear written notes on what was tested and why a choice was made, so decisions don't get revisited from scratch.
2. LLM & Conversational AI Development
- Build and improve conversational AI workflo
