The Role

As a Staff Software Engineer on our Satori AI Platform team you will drive the architecture of the internal platform that every Proofpoint product team uses to build agentic applications spanning AI-assisted development evaluation-based release gates OpenTelemetry observability for agents in production and cross-product AuthX for AI workloads. 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 Anthropics 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 products
  Design 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
