Data Science Advice Hour · E-commerce

About this task

This Series B subscription commerce company (51–200 employees) is looking for a senior Data Scientist for a paid one-hour session with a senior specialist. A senior data scientist's view on one decision.

A short, focused session replaces days of internal debate. It sells online, so volumes move with promotions and the calendar matters.

The work is fully remote. Any location in Spain works, with a few hours of overlap with the team's day. The call is booked at a time that suits you, evenings included. About 2 hours a week should overlap with the team's day (CET).

What you deliver

• Review a start-up's data plan and answer three questions on what to build first and what to buy.
• No preparation outside the hour unless you both agree to extend
• Pointers to sources you relied on, so the company can check them
• One focused hour, with the questions sent to you the day before

How the work runs

• Day 1: scope confirmed in writing, files shared
• Middle of the period: draft shared for early feedback
• Last day: final version and handover note

Duration: One session of about an hour. Accepted when the output matches the agreed checklist and the sample check passes; the recruiter confirms by e-mail.

• You work as an independent contractor: you report your own income, and your recruiter sends the statements your accountant needs.
