AI Chat R&D Trainee - Full-Stack Engineer (Go Backend) - Bilingual Mandarin

CWILL•Cary, NC

9d•$80,000 - $110,000•Hybrid

About The Position

CWILL builds a post-purchase and retention suite for Shopify brands. Its AI Chat product is expanding from live chat and AI chatbots into an AI customer service and sales conversion tool, with additional AI capabilities, deeper Shopify data integration, an agent workspace, merchant settings, reporting, and system reliability improvements planned. As an R&D Trainee, you will learn by building real features with a mentor and develop toward independently owning a product module. You will work across live chat, AI customer service, Shopify data, merchant administration, and reporting; contribute to API integration, data processing, business logic, and UI improvements; troubleshoot production issues; and help develop AI and Shopify capabilities. The role is based in Cary, North Carolina, and requires relocation if you live elsewhere. The work setting is hybrid. The growth path is to understand the architecture and complete small features and bug fixes with a mentor within three months; independently own small features or submodules from coding through release and diagnose common production issues within six months; and own a product module or technical area at junior-engineer level within twelve months.
