Job description

Summary

Do you want to help build some of the largest and most consequential enterprise and customer technology systems in the world? Join Apple’s Information Systems and Technology (IS&T) organization. IS&T is the engine behind everything Apple does for customers and for the people who build for them. It’s Apple’s central nervous system. Supporting 2.5 billion active Apple devices, processing billions of secure transactions, and keeping the technology that defines modern life running flawlessly, IS&T makes the impossible feel effortless.

Do you love building solutions to handle global complexity and immense scale? Imagine what you could do here.

Employee Experience and Productivity (EEP) is part of IS&T and delivers some of the most widely used communication and productivity technology and services across Apple — from tools that enable collaboration to the support teams that keep Apple's workforce running. EEP also leads user experience design and research, and manages the systems behind Apple’s original content studios. Within this team is Employee Engagement & Engineering, a small, global team that quickly delivers with long-term vision, building durable, reliable systems meant to last. Our focus is on crafting high-quality, user-centred experiences — delivering AI and system interoperability to make every interaction intuitive, seamless, and genuinely useful for the people who rely on our tools.

Description

As a Senior Full Stack Software Engineer, you will be a key contributor to web applications powered by Python and PHP backends, with frontends spanning React, Vue, and server-rendered templates, guiding technical direction across the stack. You take ownership of complex, ambiguous problems across the frontend, API, and data layers — including internal Model Context Protocol (MCP) servers that power AI and system interoperability — and you drive technical decisions that shape how these pieces work together.

You operate with significant autonomy on complex work, applying best practices and critical judgment with minimal guidance. You identify opportunities to improve reliability, developer experience, and user-facing quality, and you extend your impact across related teams and cross-organization initiatives. The team's size means your technical decisions have direct, outsized impact on the applications thousands of Apple employees use every day.

Responsibilities

• Guide the technical direction and implementation of complex features spanning frontend interfaces (React, Vue, or server-rendered templates) and Python and PHP backend services
• Design scalable APIs, data models, and service architectures — including internal MCP servers that expose tools and data to AI systems
• Drive features through their full lifecycle: from concept and design through deployment and operational excellence
• Apply and help raise engineering best practices across the full stack — frontend architecture, API design, testing strategies, and performance
• Identify technical risks and dependencies early; develop mitigation strategies and drive resolution
• Mentor and share knowledge with colleagues across both frontend and backend disciplines
• Contribute to cross-organization initiatives, expanding your impact beyond the immediate team
• Partner with product managers and stakeholders to inform roadmap priorities and technical direction
• Lead post-incident reviews and drive improvements in reliability and operational quality
• Evaluate and integrate AI services and capabilities — such as MCP-based tooling — to enhance the user experience
• Contribute to hiring: interview candidates, calibrate the technical bar across the stack

Minimum Qualifications

• Deep proficiency in Python and/or PHP for backend web development, with strong API design skills
• Strong frontend experience with JavaScript and a modern framework (React or Vue) and/or server-rendered templates
• Solid command of database design — relational and non-relational — and query optimisation, plus experience with cloud infrastructure (AWS) and deployment automation
• Demonstrated ability to lead technical design and mentor other engineers

Preferred Qualifications

• Experience building and operating production web applications at scale
• Experience building MCP servers or other AI tooling and service integration — LLM APIs, RAG architectures
• Familiarity with backend frameworks such as Flask, FastAPI, Laravel, or Symfony
• Experience with observability, monitoring, and site reliability practices
• Track record of driving engineering quality improvements across a team
• Familiarity with infrastructure-as-code and container orchestration (Docker, Kubernetes)
• B.S. or M.S. in Computer Science, Software Engineering, or equivalent experience
