Data Scientist CV example

Experienced · UK CV · set in the Data & AI template

Data science CVs fail most often by describing methods without outcomes. A hiring manager wants the business question, the approach in a phrase, and what changed because the model shipped. Statistical judgement shows in how honestly results are reported.

The order, and why

A one-line profile; experience as the main block; selected projects; education; skills grouped by type.

Weak bullets, made strong

Weak: Developed machine learning models to predict churn

Strong: Shipped a churn model (gradient boosting, 0.81 AUC) driving a retention offer that reduced monthly churn from 4.1% to 3.4% in an A/B test

Problem, method, accuracy and the measured business result.

Weak: Created dashboards for stakeholders

Strong: Replaced 14 manual reports with one self-serve Looker model, saving the finance team 2 days a month

Specific, counted and tied to someone who benefited.

Mistakes to avoid

  • Accuracy figures with no baseline or test design.
  • Listing every library rather than the work.
  • No sign that anything reached production.
