Staff Software Engineer - AI Platform Team

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.

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
