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. Go Big or Go Home! Paytm Labs believes in diversity and equal opportunity and we will not tolerate any forms of discrimination or harassment. Our people are critical to our success and we know the more inclusive we are, the better our work will be. We thank all applicants, however, only those selected for an interview will be contacted. Paytm Labs is committed to meeting the accessibility needs of all individuals in accordance with the Accessibility for Ontarians with Disabilities Act (AODA) and the Ontario Human Rights Code (OHRC). Should you require accommodations during the recruitment and selection process, please let us know.
