How to use these security engineer keywords
- Start from the job post, not this list. This list shows what is common. The post you apply to shows what that recruiter will search for.
- Use the post's exact words. If the post says "Python", write "Python", not a synonym. Recruiters search with the words from their own post.
- Prove each keyword in a bullet. A skills list helps the search. A bullet with a result convinces the person who reads it.
- Leave out what is not true. An interviewer will ask about every keyword on your resume.
Where these numbers come from
On November 8, 2026 we collected 16,943 open job posts from 98 companies through their public Greenhouse, Lever, and Ashby job board APIs. We sorted posts into roles by job title and removed duplicates. Then we matched each post against a fixed list of keywords and their common spellings. To keep one large company from setting the result, we used at most 25 posts per company per role. Most of these companies are US tech companies, so the shares can differ in other industries.
