We Are Zeals - “Designing conversations. Driving conversions.”
Zeals is not another chatbot. Our automated chat solution and conversational technology change how consumers purchase or act online. Zeals converts customers who appear "unengaged" to become "valuable" through designed chat on Messaging Apps. Using AI-powered, human-designed conversation flows across chat platforms, Zeals enables brands to build personalized, automated conversations with their consumers and develop a deeper understanding of their preferences while creating a delightful, seamless shopping experience. Our last 3 years have been phenomenal. We have captured the heart of many businesses in Japan, with over 480 enterprises relying on our chat commerce offering to boost their mobile business.
The goal is simple: to “revolutionize hospitality on the Internet” by unlocking digital customer service experiences that were limited to physical stores previously.
Just Getting Started…
With more than 480 enterprise companies worldwide already utilizing our product, we are perfectly poised to seize market share and fuel exponential growth in the US market, with an eye on global expansion. Investors have taken note of our potential, leading us to recently secure nearly $40 million in funding, backed by Salesforce Ventures.

As a Principal Backend Engineer at Zeals, you won’t just write code — you will own systems end-to-end, shape our architectural strategy, and influence technical direction across teams. You will be a key technical leader in our backend domain, responsible for designing scalable, fault-tolerant systems that power mission-critical services and accelerate the impact of our conversational commerce platform.
This role is not about following roadmaps — it's about creating them. You’ll work across teams to raise the engineering bar, mentor senior engineers, and drive strategic decisions that shape our product and infrastructure for years to come.
