AI/Machine Learning Experience Engineer

Who are we? Equinix is the world’s digital infrastructure company®, shortening the path to connectivity to enable the innovations that enrich our work, life and planet.

A place where tech thinkers and future builders turn bold ideas into breakthrough experiences, we welcome your unique perspective.

Help us challenge assumptions, uncover bias, and remove barriers - because progress starts with fresh ideas. You’ll find belonging, purpose, and a team that welcomes you - because when you feel valued, you’re empowered to do your best work.

Job Summary Designs, builds and improves the user and builder experience of Equinix’s AI products and platforms, including conversational AI, agents and agent-building tools. Combines interaction design with engineering: prototypes working interfaces and conversation flows, tests them with real users and builders, and ships the results into production. Makes AI behavior understandable and controllable: clear responses, visible sources, graceful failure, human escalation and easy feedback. Measures experience quality with data and converts findings into product and engineering changes. Works in a team with senior engineers, designers and product managers, and with platform, security and business partners.

Knowledge and Application Applies solid knowledge of human-AI interaction principles, conversation design and front-end engineering, plus working knowledge of LLM and agent concepts (prompting, retrieval, tool calling, orchestration). Understands usability research methods, accessibility standards (WCAG) and experience metrics. Understands what builders need from agent and platform tooling: clear APIs, documentation, debugging and observability. Follows established design and engineering standards and suggests improvements.

Complexity and Problem Solving Works on problems of defined scope where analysis requires evaluation of identifiable factors. Diagnoses why users or builders struggle (unclear responses, wrong expectations, missing controls, poor tooling) using usage data, session traces and feedback, and applies existing patterns to fix it. Judges whether a metric reflects real experience quality. Escalates unusual or high-impact issues. Work is reviewed at defined checkpoints.

Collaboration and Interaction Works with AI engineers, product managers, designers, researchers, platform and security teams. Explains usability findings and design tradeoffs to partners who are not familiar with the subject. Gathers input from end users and builders, and shares knowledge with the team.

Responsibilities

Experience engineering

• Build interactive prototypes and production interface components for AI products: chat and voice flows, agent workspaces, builder consoles and admin tools
• Design and implement conversation flows and response patterns: tone, structure, clarifying questions, source citations, confidence cues, error handling, and handoff to a person
• Implement controls that keep users in charge: review and edit before action, confirmation for high-impact steps, undo, and clear scope of what the AI can do
• Capture feedback inside the product (ratings, edits, dismissals) and route it to the teams that act on it
• Contribute to a shared component library and design system for AI interfaces
• Write unit and end-to-end tests for interface components

Builder and developer experience

• Improve the experience of people who build on the platform: onboarding, documentation, templates, SDKs, and tools for testing and debugging agents
• Reduce time to first working agent, and track where builders get stuck

Research and measurement

• Plan and run usability tests, interviews and session reviews with users and builders
• Define and track experience metrics: task completion, time to complete, adoption, retention, escalation rate, satisfaction, and builder time to first use
• Work with evaluation engineers to add experience criteria (clarity, helpfulness, appropriate tone) to evaluation rubrics and acceptance tests
• Turn findings into prioritized recommendations and backlog items

Quality and responsible practice

• Apply accessibility, localization and inclusive design requirements
• Work with InfoSec and Legal on disclosure, consent, data-handling notices and AI-generated-content labeling
• Check that interface behavior matches model and policy behavior (what the AI says it can do, versus what it can do)

Qualifications

Required

• 1-4 years in front-end, full-stack, design engineering, UX engineering or AI/ML engineering
• Bachelor’s degree in computer science, human-computer interaction, design, engineering or a related field, or equivalent experience
• Proficiency in JavaScript or TypeScript and a modern front-end framework (e.g., React), and working Python for prototyping with models and APIs
• Portfolio or work samples showing shipped or prototyped interfaces, including at least one that uses LLMs or conversational interaction
• Working knowledge of LLM applications (prompting, retrieval, agents) and of how model behavior affects the user experience
• Familiarity with usability testing methods and accessibility standards
• Ability to read usage data and write basic SQL
• Clear written and verbal communication, including with non-technical partners

Nice to have

• Experience designing for conversational AI, voice interfaces or agent-builder tools
• Experience with design tools (e.g., Figma) and design systems
• Experience with product analytics, A/B testing or session-replay tools
• Experience with LLM evaluation or observability tools
• Experience building developer tools, SDKs or documentation
• Familiarity with responsible-AI guidelines for human-AI interaction
• MS in a related field

What success looks like

• Users complete target tasks with AI products faster and with fewer escalations, tracked on a shared metric set
• Builders get a first working agent faster, with fewer support requests
• Every AI product has defined experience criteria that are tested before release
• User feedback reaches the backlog and becomes shipped changes
• The engineer takes on larger, less defined work each quarter with decreasing guidance
