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, 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 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

What you bring to the team

• Prior experience taking agentic or LLM-based systems to production - not just prototypes - including the eval, observability, and rollback story

• Deep experience with Python (typed) and/or TypeScript/Node, plus an opinion on which belongs where in the Satori AI Platform

• Hands-on work with agent frameworks (LangGraph, OpenAI/Anthropic Agents SDK, MCP, LangChain) and eval tooling (LangSmith, Braintrust, promptfoo, or similar)

• Strong fluency with OpenTelemetry, including the GenAI semantic conventions, and a track record of debugging distributed systems from traces

• Ability to see the big picture, collaborate with cross-product teams, and drive architectural conversations

• Experience designing, developing, and supporting applications in a microservices cloud environment

• Excellent verbal and written communication skills - you can convince another team's tech lead to adopt your platform

• Passion, curiosity, integrity, and outstanding attention to detail while performing tasks

• A "get it done" attitude consistent with a team where everyone writes code

• A B.S. or M.S. in Computer Science or related field, or equivalent experience
