From the employer
At Tapcart, we believe every brand needs a direct relationship with their customers - one they actually own.
We are the mobile commerce engine that powers shopping for Shopify's fastest-growing brands. $15B+ in revenue processed. 200M+ shoppers worldwide. Brands like Princess Polly, Béis, Forever 21, and Young LA rely on us to power a large portion of their revenue.
We're a lean team with minimal management and big autonomy. Everyone here builds and code is core to what we do - engineers, product, leadership. We use our own platform, we talk to merchants daily, and we ship constantly. Backed by Shopify, Silver Lake and other top VCs. Profitable and growing
If you want a place where you own real outcomes, not just tickets, you'll fit in.
Why you should join Tapcart, when you have a sea of other options?
You want to work with colleagues who have high standards and who love building beautiful, performant software
You prefer the dopamine of working on software that will get into hundreds of millions of users' hands, vs working on enterprise, forward-deployed software
We deeply care about using AI in our work. Don't proceed with applying if:
You don't love agents / don't use them daily
You don't value craft and cannot speak to software that inspires you
What you’ll be working on at Tapcart
Architect and ship core product that feels durable, fast and clean. Work across multiple stacks to deliver impact.
Design our proactive AI agent orchestration layers used by thousands of high growth brands
Prototype new interaction patterns for human-agent collaboration
Raise our bar for engineering craft, help with recruiting, and hold the line on quality
Dogfood the platform and our apps every day :)
You'll be a true owner, from prototype to production, and work side‑by‑side with the CEO, design, and key stakeholders, all while staying close to merchants to deliver value early and iterate quickly.
