Dear [Hiring manager's name],

I'm applying for the Data Scientist position at [Employer], which I found on [where you saw the posting]. I bring [number] years of experience as a Data Scientist, most recently [the scope you are responsible for].

At [Current or most recent employer], I analyzed, manipulated, or processed large sets of data using statistical software for [how many / how often], and I created graphs, charts, or other visualizations to convey the results of data analysis using specialized software, which [result you can prove: time saved, errors cut, people served]. I also tested, validated, and reformulated models to ensure accurate prediction of outcomes of interest, using [a tool the posting names, for example Apache Hadoop, only if you have used it].

Your posting mentions [a priority from the job description]. That is where my mathematics and critical thinking matter most: [one short, true example of you doing it].

I'd welcome a conversation about how I could help [Employer] with [that priority]. Thank you for your time.

Sincerely,
[Your name]

1. Opening. Names the role, Data Scientist, and where you saw it, then states your experience in the role.
2. Proof. “Analyze, manipulate, or process large sets of data using statistical software” and “Recommend data-driven solutions to key stakeholders”, in the past tense, plus your scale and result.
3. Skills. Mathematics and Critical Thinking, the top-rated skills, get a real example.
4. Tools. Apache Hadoop stays in brackets: O*NET data, not your experience.

• Listing tools you haven't used: the tools above describe the job, not you.
• Describing duties instead of results: “Analyze, manipulate, or process large sets of data using statistical software” is the job, not an achievement.
• Leaving out a license, certification or degree the posting asks for, when you hold it.
• Ignoring Mathematics, a knowledge area O*NET rates important here.
