Staff Platform Engineer - AI Infrastructure

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.
