Software Engineer - Agent Development

Job Summary

Apple is where individual imaginations gather together, committing to the values that lead to great work. Every new product we build, service we create, or Apple Store experience we deliver is the result of us making each other's ideas stronger. That happens because every one of us shares a belief that we can make something wonderful and share it with the world, changing lives for the better. It s the diversity of our people and their thinking that inspires the innovation that runs through everything we do. When we bring everybody in, we can do the best work of our lives. Here, you ll do more than join something - you ll add something. There are countless ways you can contribute here, from working on apple. com to software for digital physical Apple Stores, from software for Apple Care to Apple-wide systems for identity, operations, recruiting, and people management, from software for Apple data centers to Apple-wide data processing AI/ML systems. Apples IST team builds the tools, platforms, and services that power the people who build Apple. Our Customer Systems group is reimagining how Apple engineers work through intelligent, autonomous systems - and were looking for an Agentic AI Developer to help lead that effort.

We are looking for a talented Agentic AI Developer to join Apple's IST Customer Systems team. In this role, you will design, build, and operate intelligent autonomous agent systems end-to-end - both client-side and server-side. You will architect agents that reason, plan, remember, and act reliably across long-running workflows, with deep attention to memory design, multi-agent orchestration, observability, and maintainability. This is a deeply technical engineering role with a high bar for production quality. You will own the full lifecycle of agentic systems: from agent architecture and memory design, to tool integration, observability, and safe deployment. While the primary focus is agent engineering, a solid understanding of the Java tech stack, React, and TypeScript is also important, as you will work across both server-side and client-side surfaces. You will collaborate closely with engineers, product managers, and platform teams across Apple to bring AI capabilities into the developer tools our teams depend on every day.

Responsibilities

• Design and implement multi-agent orchestration systems - including agent collaboration, task delegation, hand-offs, shared context management, role specialisation, and conflict resolution patterns
• Build agent memory architectures - episodic, semantic, and working memory - using vector stores (pgvector, Milvus) and hybrid retrieval strategies to enable agents to reason over past interactions and maintain state across sessions
• Develop tool and function-calling layers that expose internal APIs and services as agent-executable tools via MCP (Model Context Protocol) servers or custom tool registries, with strong contracts and well-defined failure semantics
• Implement RAG (Retrieval-Augmented Generation) pipelines with vector stores and hybrid retrieval strategies to ground agent responses in authoritative internal knowledge
• Own the observability story for agentic systems - distributed tracing of agent runs, prompt and response capture, token and cost accounting, evaluation pipelines, replay and debugging, and regression detection using OpenTelemetry and LLM observability tooling
• Drive maintainability of agentic systems through versioning of prompts, tools, and agent graphs; deterministic test harnesses; evaluation suites; safe canary rollouts; and structured logging that makes non-deterministic behaviour debuggable
• Apply agent safety guardrails - input validation, prompt-injection defences, output schema contracts, and sandboxed code execution - to ensure systems are safe and reliable at production scale
• Architect and maintain server-side agent services using Java (Spring Boot, Spring AI) and client-side agent interfaces using React and TypeScript

Qualifications / Requirements

• While the primary focus is agent engineering, a solid understanding of the Java tech stack, React, and TypeScript is also important, as you will work across both server-side and client-side surfaces.
