The Role
As a Software Engineer on our Satori AI Platform team, you will help build 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 components and primitives you build will help define how mission-critical agentic software ships across the company. 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. If this challenge and environment for growth excites you, we want you to join our team.
Your day-to-day
* Build platform components in Python (with strong typing) and TypeScript/Node — SDKs, services, and CLIs that product teams adopt and extend
* Contribute deeply to one or more of our platform pillars: AI-assisted developer workflows, eval-driven release gates, OpenTelemetry instrumentation for LLM/agent traffic, cross-product AuthX, etc.
* Implement and harden agent runtimes built on frameworks like LangGraph, OpenAI Agents SDK, Anthropic's Agent SDK, and MCP
* Wire up evaluation pipelines (LangSmith, Braintrust, promptfoo, or similar) that gate releases on real quality and safety signals
* Instrument agentic systems with OTel and the GenAI semantic conventions so we can debug latency, cost, and quality in production
* Partner with product teams onboarding to the platform; resolve bugs and field integration questions
* Evaluate new design & code patterns regularly; learn new techniques and technologies as a result of peer review and mentorship; share what you have learned with your peers
What you bring to the team
* Prior experience shipping production Python (typed) and/or TypeScript/Node services
* Working knowledge of at least one agent framework or LLM SDK (LangGraph, OpenAI/Anthropic Agents SDK, MCP, LangChain, or similar)
* Familiarity with evaluation, prompt iteration, or LLM observability tooling — and an opinion on what "good" looks like
* Comfort working with non-deterministic systems: you instrument first, debug from traces, and trust evals over anecdotes
* Experience designing, developing, and supporting applications in a microservices cloud environment
* Knowledge of CI/CD and working with tools like Jenkins or similar
* Strong conviction to solve critical business problems in an efficient manner, building on your experience in a mature software development lifecycle (SDLC)
* A B.S. or M.S. in Computer Science or related field, or equivalent experience
