Churn or Conversion Model

About this task

This digital health company (1,001–5,000 employees) is looking for a senior Data Scientist for a single piece of work with a fixed scope and a fixed price. A model that predicts who leaves or buys, with its accuracy explained.

The work is too small to justify a hire and too important to leave to chance. It works in healthcare, so patient data is never part of the task and privacy rules are strict.

The work is fully remote. Any location in Germany works, with a few hours of overlap with the team's day. Evenings or weekends are fine, as long as the agreed weekly output is there. About 1 hour a week should overlap with the team's day (CET).

What you deliver

• Build and validate a churn model on 20 months of customer data and explain the top drivers in plain language.
• A final note stating what was checked and what was left out of scope
• The finished deliverable in the agreed file format, with sources and assumptions listed
• A 20-minute walkthrough call, or a recorded screen share if you prefer

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: 1 to 2 weeks. Accepted when the company contact confirms the deliverable against the written checklist. One round of edits is included.

Tools

How you get paid

• The company prepays Deftridge before your first hour, so payment does not depend on a late invoice.
• Deftridge pays you in EUR after the company confirms the hours or the deliverable. The payment date is written in your task agreement.
• You work as an independent contractor: you report your own income, and your recruiter sends the statements your accountant needs.
