Your direct users are fellow product engineers, and the products they ship protect business-critical communications for Fortune 100 customers 24/7/365. The patterns and primitives you set will define how mission-critical agentic software ships across the company. This is a uniquely-challenging role: we empower small teams to make large impacts, the systems are inherently non-deterministic, and the bar for what we ship to product teams is high. Your day-to-day * Set architectural direction for one or more platform pillars: AI-assisted developer workflows, eval-driven release gates, OpenTelemetry for LLM/agent traffic, cross-product AuthX, etc. * Design agent runtimes and SDKs on frameworks like LangGraph, OpenAI Agents SDK, Anthropic's Agent SDK, and MCP, in Python (typed) and TypeScript/Node * Define what "release-ready" means for an agent at Proofpoint: the eval suites, safety checks, telemetry, and AuthX contracts that gate every rollout * Partner with product team tech leads across the org to land your architecture in their stacks; turn one-off integrations into reusable platform capabilities * Drive the standards for prompt management, model selection, cost/latency budgets, and observability across productsDesign, code, review, test, and deploy software features in our application stack - Staff engineers at Proofpoint still write code * Mentor engineers across the platform and product teams; raise the company-wide bar for what production agentic software looks like ## Related Videos - [Stop using Node.js like in 2020!
