Hey 👋, my name is Roman, and I am a co-founder of UM | Shopify Marketing Agency. We help e-commerce brands scale through performance and retention marketing.

We often work with businesses that have a strong product and existing demand, but low website conversion. At the unit economics level, it is clear that many of these projects can scale, but only if the website is properly optimized. This is currently a bottleneck in our process.

That is why we are looking for a Shopify CRO Developer on a project-based basis. At the start, this is collaboration on specific client projects. After successful cases and proven results, we are open to discussing deeper integration into the Team.

First things first: what we offer

This is project-based work without micromanagement or chaos. We clearly define tasks, provide full context, and expect results. Payment is per project, with all terms agreed transparently before we start.

We respect people’s time. We do not disappear, we do not delay feedback, and we do not change the rules midway. Our goal is to build long-term collaboration, not to simply “close tasks.”

About the role

We are looking for a specialist who thinks like a marketer but has the technical stack to work confidently with Shopify stores.

You will join projects where:

• We have already completed an audit and clearly see growth opportunities
• Paid traffic does not work in numbers without conversion improvements
• Fast implementation of CRO solutions, ad-driven changes, or advertorial pages is required

You will work closely with media buyers, email marketers, and strategists. The focus is always on the client’s business results, not on the number of revisions delivered.

Technical skills that matter to us

We expect hands-on experience with Shopify and a solid understanding of its architecture. You should be comfortable working with themes, sections, and blocks, customizing templates, using metafields and metaobjects, and understanding the capabilities and limitations of the Shopify checkout. Confident work with Shopify Liquid is essential — reading and modifying existing code, handling conditions and loops, working with product, collection, cart, and customer objects, and creating custom sections without hacks. On the frontend side, you should be comfortable with HTML, CSS, and JavaScript for responsive, mobile-first interfaces and UI logic. From a CRO perspective, it is important to understand how technical changes affect conversion, site speed, and mobile performance. Experience working with heatmaps and session recordings, avoiding app overload, and building advertorial pages for paid traffic is highly valued. Experience with A/B testing is a plus.

Who we are looking for

This role is a good fit if you already have real experience with Shopify and CRO. We expect you to think in terms of user journeys, unit economics, offers, guarantees, bonuses, and objections, and to clearly understand how your decisions impact conversion.

This is not a fit if:

• You are only looking to “close tasks” without ownership of results
• You do not accept feedback and tend to shift responsibility
• You are not interested in the client’s business performance
• Or it is just another project for you, without real engagement

How collaboration works

We start with one or several projects and evaluate results, pace, communication, and overall working comfort. If there is mutual trust and strong outcomes, the collaboration can scale.

We are open to an in-house format in the future, but we do not promise it upfront. Real cases and shared results come first.

Our process

1. You submit the application form.
2. If we see a good match, we schedule an interview and discuss the first project and collaboration format.

I personally review all applications and get back to candidates we would like to move forward with.

If this format resonates with you and you are looking for a team without chaos that values strong specialists and business thinking, we will be glad to connect.

Roman

Co-founder, UM Shopify Marketing Agency
