AI Application Development Engineer Intern (Corporate Service System - Procurement) - 2027 Start

About the Team
We are upgrading the traditional procurement system into an AI-native procurement platform, with a strong focus on building Procurement Agents. As part of ByteDance's Corporate Information department, we design and operate corporate service systems that support the company's global business growth and improve the day-to-day work efficiency and experience of employees worldwide.
Procurement is a complex, high-value domain full of long workflows, rich business rules, and real decision-making. It is one of the most promising places to apply cutting-edge AI Agent technologies to real, large-scale problems. We are reimagining how employees and business partners interact with procurement through intelligent agents, and building the underlying System AI Harness that lets agents plan, act, and deliver reliably.

As an intern, you will work alongside experienced engineers at the frontier of AI Agent engineering, get hands-on with real problems from day one, and receive mentorship to grow quickly. It is a great opportunity to explore emerging AI technologies, learn how a complex business domain works end to end, and make a real contribution during your internship.

We are looking for talented individuals to join us for an internship. Our internship program offers students hands-on experience, industry exposure, and opportunities to apply their knowledge to real-world challenges while building a strong foundation for personal and professional growth.
Interns will gain practical experience, explore potential career paths, and participate in social events, learning programs, and development workshops alongside industry professionals.
Candidates may apply to a maximum of two positions across Our Company and its affiliates globally. Applications will be considered in the order they are submitted.
Applications are reviewed on a rolling basis, so we encourage you to apply early. Please clearly state your availability in your resume, including your start and end dates.

Candidates who pass resume screening will be invited to participate in Our Company's technical online assessment.
