Senior AI Engineer

Paytm · Toronto, Canada

About the role
There’s a wide gap between an agent that works in a demo and one that works across millions of live transactions. Closing it is the job. You’ll embed with the teams and customers who depend on AI — risk, fraud, collections, payments, support, developer experience — and design, build, and ship agentic systems into their production environments. You’ll also help build the platform underneath: Paytm’s AI inference platform (Pi) and the agentic runtime, orchestration, and tooling that lets agents reason, plan, use tools, and run multi-step workflows safely.

What you’ll do

  • Embed & deploy
  • Tackle greenfield problems alongside internal teams and customers — scope ambiguous needs and build agents from scratch that fit how they actually work.
  • Own deployments end-to-end: discovery, build, integration, activation, and the tuning that earns trust and adoption.
  • Lead pilots and demos, drive adoption, and clear blockers before they stall a rollout.

  • Build agentic systems
  • Architect agentic systems — reasoning, planning, tool use, memory, multi-agent coordination — that run real workflows with guardrails.
  • Build safe tool-use infrastructure across APIs, databases, and services, with permissioning, sandboxing, and human-in-the-loop.
  • Ship SDKs, patterns, and reusable blueprints so internal teams build and deploy agents fast.

  • Make it reliable
  • Design and run rigorous evals: measure quality, catch regressions, and feed results back into the system.
  • Build observability, tracing, and guardrails that prove agents are safe and keep them safe as models and data drift.
  • Own the multi-model inference your agents depend on (text, voice, code, vision) — latency, throughput, and cost.

  • Lead
  • Set technical direction and standards for agentic systems; mentor engineers and partner with ML, product, and security.
  • What you’ll bring

  • 5+ years in software engineering, with 3+ in AI systems or LLM applications, and production systems shipped end-to-end.
  • Strong grasp of LLM agent architectures (ReAct, RAG, tool use, multi-agent) and hands-on agentic orchestration and evaluation.
  • Proficiency in Python across a broad stack — pipeline, agent, service, and instrumentation.
  • Production experience on AWS and Azure with containerized deployments (Docker, Kubernetes).
  • Strong customer and stakeholder instincts; able to impose structure on ambiguity and push back when needed.
  • A bias toward shipping and comfort operating without a clean spec.
  • Solid understanding of agentic security risks (prompt injection, privilege escalation, data leakage).
  • Strong written and verbal communication.
  • Nice to have

  • Agentic systems in regulated industries (fintech, payments, credit, healthcare).
  • Cloud AI/ML services (AWS SageMaker / Bedrock, Azure ML / Azure OpenAI); multi-cloud or hybrid.
  • MCP or agent communication standards; agent evaluation and observability tooling.
  • Model serving (vLLM, TensorRT-LLM, Triton), fine-tuning, quantization, or LoRA.
  • Workflow orchestration (Temporal, Airflow, Prefect) for AI workloads; voice / multimodal / edge inference.
  • Testing and verification for non-deterministic AI systems.
  • AI Engineering pay context
