About the job

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.
