JOB DESCRIPTION

At eBay, we're more than a global ecommerce leader — we’re changing the way the world shops and sells. Our platform empowers millions of buyers and sellers in more than 190 markets around the world. We’re committed to pushing boundaries and leaving our mark as we reinvent the future of ecommerce for enthusiasts.

Our customers are our compass, authenticity thrives, bold ideas are welcome, and everyone can bring their unique selves to work — every day. We're in this together, sustaining the future of our customers, our company, and our planet.

Join a team of passionate thinkers, innovators, and dreamers — and help us connect people and build communities to create economic opportunity for all.

Role Overview

We’re hiring a Junior AI/ML Agent Engineer with a front-end focus to build agentic workflows and tools that integrate LLMs, OpenAI specs, MCP, and modern frontend frameworks. You’ll collaborate with product and platform teams to deliver intuitive web experiences that harness AI agents for developer and business workflows.

Key Responsibilities

Design and implement agentic workflows demonstrating LLMs (Claude, OpenAI), MCP clients/servers, and OpenAI specifications for tool/function orchestration.
Build user-facing features in AngularJS and ReactJS, with services and tooling in Node.js and Python for agent integration.
Implement prompt engineering, tool schemas, and function calling patterns; handle context windows, memory, and retrieval strategies for agent reliability.
Integrate agents with developer ecosystems: GitHub (actions, PR comment bots), Cline (AI coding assistant workflows), and Claude model endpoints.
Develop reusable UI components and SDKs for agent invocation, status visualization, and error handling; contribute to design systems and accessibility.
Ship high-quality code with unit/e2e tests, CI/CD, and observability (logs, metrics, traces) for agent runs and UI flows.
Document architecture, OpenAI/MCP spec contracts, and developer guides for internal consumers.

Minimum Qualifications

2–5 years of professional experience in software engineering with front-end emphasis.
Hands-on experience building with LLMs (OpenAI, Claude) and agent/workflow patterns (tools, function calling, retries, guardrails).
Working knowledge of MCP (Model Context Protocol) concepts and implementation of clients/servers.
Proficient in AngularJS and/or ReactJS, plus Node.js and Python for agent backends and tooling.
Familiarity with OpenAI specifications (tool definitions, schemas) and API integration best practices.
Experience integrating with GitHub (Actions, APIs), and exposure to Cline and Claude models and strong fundamentals: TypeScript/JavaScript, REST/GraphQL, testing (Jest/Cypress), linting, and accessibility.

Preferred Qualifications

Experience with RAG pipelines, embeddings, or lightweight vector stores for context augmentation.
Basic security awareness for agent design: input validation, secrets management, rate limiting, and least-privilege tokens.
Observability with Datadog/OpenTelemetry or similar for agent runs and UI interactions.
Knowledge of prompt versioning, evaluation (e.g., golden sets), and experiment design.

What We Value

Eagerness to learn and adapt to emerging models/agent frameworks.
Bias for action, pragmatic problem-solving, and ownership of outcomes.
Clear communication and collaborative mindset across product, design, and infra.

Salary & Benefits

Competitive mid-level compensation with benefits. Final level and pay depend on experience and interview performance.

How to Apply

Submit your resume, GitHub/portfolio links, and a brief note describing an agent or AI-enabled feature you’ve built, including frameworks, models, and evaluation approach.
