About Proofpoint

Proofpoint is a global leader in human- and agent-centric cybersecurity, protecting how people, data, and AI agents connect across email, cloud, and collaboration tools.

Role Overview

As a Staff Software Engineer on the Satori AI Platform team, you will drive the architecture of the internal platform that all Proofpoint product teams use to build agentic applications, including AI‑assisted development, evaluation‑driven 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.

Responsibilities

• 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 such as LangGraph, OpenAI Agents SDK, Anthropic's Agent SDK, MCP, in Python (typed) and TypeScript/Node
• Define what “release‑ready” means for an agent at Proofpoint, including eval suites, safety checks, telemetry, and AuthX contracts that gate every rollout
• Partner with product team tech leads to land your architecture in their stacks and turn one‑off integrations into reusable platform capabilities
• Drive standards for prompt management, model selection, cost/latency budgets, and observability across products
• Design, code, review, test, and deploy software features; write production‑grade code as a Staff engineer
• Mentor engineers across the platform and product teams to raise the bar for production agentic software

Qualifications

• Experience developing and supporting AI‑powered applications, with exposure to agentic or LLM‑based systems in development, testing, or production environments
• Proficiency in Python and/or TypeScript/Node.js, with ability to write maintainable, scalable, and well‑tested code
• Familiarity with agent frameworks such as LangGraph, LangChain, OpenAI/Anthropic Agents SDK, MCP, or similar technologies
• Experience with evaluation, monitoring, and observability concepts for AI applications (e.g., LangSmith, Braintrust, promptfoo, OpenTelemetry)
• Experience troubleshooting application and service issues using logs, metrics, traces, and diagnostic tools
• Ability to collaborate effectively with engineering, product, and platform teams to deliver solutions and resolve technical challenges
• Experience designing, developing, and supporting applications in cloud‑based and/or microservices environments
• Strong written and verbal communication skills
• Demonstrated curiosity, attention to detail, and willingness to learn new technologies and apply feedback
• Proactive, team‑oriented mindset with ownership of work and contribution to team success
• B.S. or M.S. in Computer Science or related field, or equivalent practical experience

Benefits

• Competitive compensation
• Comprehensive benefits and wellness program
• Flexible work environment
• Annual wellness and community outreach days
• Recognition of contributions
• Global collaboration and networking opportunities
