Software Engineer 5 – Agent Platform, AI Platform

Netflix is hiring a Software Engineer 5 for its Agent Platform team, part of AI Platform. The team builds the infrastructure Netflix engineers use to take an AI agent from zero to production without rebuilding the same pieces each time. This role is for an engineer with deep experience building, deploying, operating, and evaluating LLM agents in production, not just chat-completion apps or prototypes.

The Agent Platform team owns the foundational building blocks the rest of the company builds on: the Model Gateway for unified access to external LLMs like Claude, GPT, and Gemini, the Assistance API for conversational use cases, the MCP Gateway connecting agents to Netflix's internal systems and knowledge, the Agent SDK, and an end-to-end evaluation stack. The team is small with outsized leverage, and what it ships becomes the foundation for AI across all of Netflix.

What you will do

• Design, build, and operate the Agent SDK and MCP Gateway that Netflix engineers use to build, deploy, and run AI agents in production.
• Build agents and agent infrastructure across the full lifecycle: plan/act/observe loops, tool and MCP integrations, deployment, and day-2 operations.
• Make evaluation a first-class part of the platform by building tracing, eval suites, and quality signals that let teams measure agents, catch regressions, and iterate.
• Own reliability, observability, and guardrails for non-deterministic systems running at very high scale.
• Lead cross-functional initiatives with ML scientists, data scientists, product managers, and other AI Platform teams.
• Iterate quickly with users to improve the developer experience while establishing durable foundational capabilities.

What they are looking for

• 8+ years of software engineering experience with a track record of delivering quality results.
• Hands-on experience building, deploying, operating, and evaluating LLM agents in production, not just chat-completion apps or prototypes.
• Experience with one or more agent frameworks or SDKs (Strands, OpenAI Agents SDK, Anthropic Claude Agent SDK, LangGraph, pydantic-ai, CrewAI, Google ADK) and with tool/function calling and MCP.
• Experience with LLM/agent evaluation and observability: building eval suites, tracing, and quality measurement, then iterating on results (Braintrust, LangSmith, W&B, or equivalent).
• Strong experience building SDKs and APIs for internal or external developers.
• Strong fundamentals in building and operating scalable, observable, fault-tolerant distributed systems.
• Proficiency in Python and Python packaging tooling, plus one of Java, Go, C/C++, Rust, or Zig. Familiarity with Temporal, FastAPI, PostgreSQL, and Kubernetes is a plus.
• Experience with large-scale build, release, CI/CD, and observability methods.
