Junior Campaign Developer (AJO)

Location: Barcelona

The purpose of this role is to assist in the development and integration of campaign platform technologies.

Job Description

Day in life: Your morning starts with the build tracker and a journey design by your colleagues. You spend the first couple of hours in the AJO email designer, assembling a welcome message from an approved template, wiring in the personalisation tokens listed in the spec, and fixing the padding that collapses in Outlook. Before lunch you push the journey into the dev sandbox, set up four test profiles, and run through the QA checklist — every link, every fallback value, every render. Two things fail, so you screenshot them, log the defects, and flag one to the mid-level consultant because you can't tell whether it's your build or the underlying schema. In the afternoon you sit in on a client working session, mostly listening and writing notes, then update the build documentation so the design and what actually exists match. You finish by reading the latest AJO release notes because your certification exam is in three weeks.

Needs

Working knowledge of the AJO canvas: journey vs campaign, events, conditions, wait, split, actions

Careful, checklist-driven, comfortable saying "I don't know".
