Staff Platform Engineer - AI Infrastructure

About the Role

As a Staff Platform Engineer - AI Infrastructure, you will build and scale the infrastructure behind
Paytm's AI inference platform, serving internal teams and enterprise customers and supporting
new customer use cases from the ground up. You will own GPU infrastructure, model hosting
and serving, and multi-model routing across modalities. This includes running our own coding
and domain-specific models (voice, vision, risk, fintech workflows) as well as third-party models
on shared GPU and accelerator clusters.

You will also build self-service platforms that let teams provision, compute, deploy and
customize models, and manage resources through APIs and control planes, so they can use AI
without rebuilding infrastructure each time.

Your work will form the AI control plane for Paytm Intelligence (Pi): policy-driven routing, quotas,
observability, and usage and cost visibility. It will directly affect how fast we ship agents and AI
features, how reliably they run, and how efficiently we use our hardware across payments, risk,
fraud, collections, support, and developer experience.
