Now hiring Marketing Cologne

Senior Shop Manager (Cologne) (m/f/d)

Own live online shops end to end: the daily changes, the campaign and event updates, the testing, and the customer journey that runs through all of it. You are the person who decides what ships, and who proves it worked.

Our Shop Management team keeps a large portfolio of online shops running, tested and improving every day. We are looking for an experienced senior person to join it and set the standard: someone the team looks to, learns from and moves faster because of.

You take end-to-end ownership of defined shops and projects: daily changes, campaign and event updates, asset implementation, testing and QA, and the coordination with Product, Development, Analytics and Creative that makes any of it ship. A core part of the work is structured testing: building a thesis, setting up A/B tests, and acting on what the numbers show. You are also expected to use AI to work faster and smarter, as a repeatable process rather than a one-off experiment.

The Customization Group is a global leader in mass customization and print‑on‑demand e‑commerce, manufacturing up to 2.5 million personalized products daily across production sites in Germany, Poland, the USA and Latvia, and reaching customers through 20+ online shops and 1,000+ partner stores: 750+ people, 40+ nationalities, 10 locations.

In a nutshell
-you run live shops end to end, you test what works, and you use AI to keep the whole portfolio moving.

What you will own, and what we need from you. Side by side, no surprises.

Ordered by share of your week: running and testing live shops takes the largest slice, and AI runs through all of it.

• Run the shops day to day.
  Campaign and event updates, hero banners, discount logic, content and asset changes, and the coordination that gets them live on time.

• Own defined shops or projects end to end.
  You hold the stakeholders, the timeline and the delivery quality, and you are the one people ask for a status.

• Launch new shops and enter new markets.
  Stand up new Shopify shops, take existing ones into new markets, and own the localization that makes them work locally: language, currency, payment and regional detail.

• Support product launches.
  New products and features go live cleanly because you helped set them up, test them and roll them out.

• Test before customers do.
  QA, and A/B tests built on a clear thesis, then the follow‑up actions the results call for.

• Improve conversion and the customer journey.
  Look at where people drop off, form a view on why, and turn it into a prioritised list of improvements.

• Use AI to get more done.
  Use AI to draft A/B test ideas, build QA checklists, adapt content across shops and speed up your reporting, so more tests ship and turnaround gets faster. You review everything before it goes live.

The must‑haves are genuine; the rest are strong pluses, not gates.

Must have

• Structured, delivery‑focused background.
  3–5 years in e‑commerce shop management, online project management, product ownership or a comparable role.

• Ownership of complex projects.
  A track record of running cross‑functional projects and delivering many different tasks on short timelines.

• Testing and conversion thinking.
  Comfort with A/B tests, QA and acting on data.

• You already work with AI.
  You use AI tools day to day to work faster and better, on analysis, drafting, QA and reporting, and you check what they give you before it goes anywhere.

• A hands‑on…
