Aptura is looking for Subject Matter Experts from marketing analytics, across paid, organic or lifecycle channels, who build CAC, attribution and campaign performance analyses in Excel. You have used AI tools on your own work and been frustrated by the mistakes they make. You will turn that experience into realistic Excel tasks that test how well AI does the work of a Marketing Analyst.
Writing realistic Excel tasks drawn from your own work: extending existing models, fixing broken ones and building from a brief
Working through each task yourself so there is a clear, correct answer
Writing yes-or-no criteria precise enough that a grader can mark any attempt against them
Start Date : Immediate
Duration: Approximately 4-6 weeks
You will be engaged as an independent contractor.
This is a fully remote role that can be completed on your own schedule.
Projects can be extended, shortened, or concluded early depending on needs and performance.
Your work at Aptura will not involve access to confidential or proprietary information from any employer, client, or institution.
Apply with your details and CV. Choose an available 30-minute group walkthrough call.
Attend the walkthrough and create one original task from your own work. Submit the brief, the actual input workbook(s) needed to complete it. Input-file uploads are compulsory.
Write the brief yourself. Input workbooks must also be human-built. Use real data that has been sanitised, or public data with the source named. No AI usage allowed.
We run your task against current frontier AI models. If the models get it wrong, you then write a detailed yes-or-no rubric, and a reviewer signs off on the task with you.
Completing onboarding does not guarantee a job offer; selection remains subject to written approval of the task proposal.
