About Us:


Proofpoint is a global leader in human- and agent-centric cybersecurity. We protect how people, data, and AI agents connect across email, cloud, and collaboration tools. Over 80 of the Fortune 100, 10,000 large enterprises, and millions of smaller organizations trust Proofpoint to stop threats, prevent data loss, and build resilience across their people and AI workflows. Our mission is simple: safeguard the digital world and empower people to work securely and confidently. Join us in our pursuit to defend data and protect people.


How We Work:


At Proofpoint you’ll be part of a global team that breaks barriers to redefine cybersecurity guided by our BRAVE core values:


Bold in how we dream and innovate


Responsive to feedback, challenges and opportunities


Accountable for results and best in class outcomes


Visionary in future focused problem-solving


Exceptional in execution and impact


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 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


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
