Description

About CWILL

CWILL (pronounced 'quill') is a post-purchase and retention suite built for Shopify brands. Reduce support tickets, recover lost revenue from returns, and turn one-time buyers into loyal fans — with tools purpose-built for every touchpoint that follows the sale.

About the Role

CWILL AI Chat is growing from a live chat and AI chatbot into an AI customer service and sales conversion tool for Shopify merchants, with more AI capabilities, deeper Shopify data integration, an agent workspace, merchant settings, reporting and system reliability on the way.

As an R&D Trainee, you'll learn by building real features with a mentor, and grow into an engineer who owns a module independently.

Builds post-purchase tools for online merchants

CWILL provides software for online merchants to manage customer activity after a purchase and encourage repeat business. Its apps combine shipment tracking, returns and exchanges with product reviews, loyalty rewards, referral programs and email marketing. Store teams use the tools to send delivery updates, resolve return requests, collect customer feedback and coordinate campaigns, while a separate chatbot answers shopper questions using store information. Merchants install individual apps or connect several products, with paid subscriptions based on selected features and usage alongside free plans. The business began in 2014 as Channelwill and is headquartered in Cary, North Carolina.
