Priya Raman

Senior Data Scientist

Austin, TX · p.raman@email.com · (555) 412-8834

Dear Hiring Manager,

I'm writing to apply for the Senior Data Scientist role on your growth analytics team. At my current company, I built a churn-prediction model that identified at-risk subscribers 21 days earlier than our existing rules engine, helping retention campaigns save an estimated $1.4M in annual recurring revenue.

I work daily in Python, SQL, and TensorFlow, and I've built pipelines processing over 40 million events a day using Airflow and BigQuery. I designed and ran the A/B test that validated a new onboarding flow, lifting activation by 17% with a p-value under 0.01, and I regularly present findings to product and marketing leaders who don't write code.

Your team's work using behavioral data to personalize the shopping experience is exactly the kind of problem I want to keep solving. I'd welcome the opportunity to walk you through my churn model and recent A/B testing framework in an interview.

Sincerely,

Priya Raman

  1. 1Opening: the role + a headline result a model or analysis produced
  2. 2Body 1: a specific project with tools, data scale, and quantified business impact
  3. 3Body 2: how you communicate insights and collaborate with stakeholders/engineers
  4. 4Closing: connection to the company's data challenges + call to action

Writing Tips for Data Scientist Cover Letters

  • Mention the scale of data you've worked with (rows, users, requests).
