Summary

Our Mission

We help ambitious eCommerce brands grow by combining sharp business strategy with Shopify expertise. We don’t just build stores — we build conversion-focused ecosystems. We’re a small, high-performing team, and we’re looking for someone who shares our obsession with quality and problem-solving.

The Role

We’re looking for a Senior Shopify Developer to join us and own the development of Shopify storefronts and custom apps. You’ll work closely with our other developers, designers, strategists, and clients to turn ideas and business goals into scalable solutions — from a blank theme to a high-performing live store.

You’re not just coding what’s asked — you’re bringing ideas, spotting technical risks, and figuring out how to make things work even when the answer isn’t obvious.

What You’ll Be Responsible For
  • Building Shopify stores from scratch using best practices and native Shopify capabilities.
  • Developing custom sections and features that elevate UX and improve performance.
  • Creating custom Shopify apps to solve complex needs when native features aren’t enough.
  • Working with our development team to align on best practices and scalable architecture.
  • Developing and maintaining internal apps and tools to streamline our processes and support client work.
  • Collaborating with strategy and UX teams to solve business challenges with tech.
  • Optimizing speed, SEO, accessibility, and overall performance of Shopify storefronts.
  • Staying ahead of Shopify updates and leveraging the latest features (metaobjects, Shopify Functions, Checkout Extensibility, etc.).
  • Debugging and troubleshooting efficiently


Must-Have Skills & Experience
  • 4+ years of experience building custom Shopify themes and apps.
  • Strong command of Liquid, Shopify APIs, JavaScript, HTML/CSS, Git.
  • Experience with Shopify Plus features
  • Ability to translate business needs into scalable tech solutions.
  • Comfort working in cross-functional teams and communicating with non-technical stakeholders.
  • You’re solution-oriented: when there’s a blocker, you don’t just say “it’s not possible” — you find another angle.


Bonus Skills
  • Experience integrating third-party systems (ERPs, PIMs, WMSs).
  • Previous agency or freelance experience working with multiple clients.
  • Experience mentoring or managing devs.


Why You’ll Love Working With Us
  • Work with a tight-knit team of senior specialists — no fluff, just impact.
  • Tackle real challenges for growing eCommerce brands — your work matters.
  • Flexible structure: we focus on results, not time-tracking.
  • We’re building a team where everyone is heard, and curiosity is valued.
  • Opportunity to grow into a leadership role as we scale.


How to Apply

We’re not in a rush — we’re looking for the right person.

If this sounds like you, send us:

  • Your portfolio (GitHub or live Shopify stores)
  • A quick note about why this sounds like your kind of challenge
  • Bonus: tell us about a complex Shopify problem you solved and how.
