About us

We build Shopify apps used by serious e-commerce brands — streetwear, fashion, lifestyle.

What you’ll actually do (no fluff)

• Build core product features end-to-end (backend, logic, edge cases, scale)
• Own parts of the system — not “tickets”, but decisions

• Debug real production issues with real consequences

Tech (what we use today)

• Backend: Node.js
• Database: MongoDB, Apollo

What we’re looking for

You should have:

• 5–7 years of real production experience
• Experience building systems that didn’t fall apart at scale
• Comfort debugging messy, real-world issues

Bonus if you:

• Have worked on SaaS or developer tools
• Understand e-commerce flows
• Have opinions (and can defend them calmly)

Why join us?

• Real ownership — your decisions ship
• Remote, async-friendly — no micromanagement
• Competitive pay (with option to work as a consultant for tax benefits)
