How to Write a LinkedIn About Section for Technical Professionals

Most LinkedIn About sections written by technical professionals fall into one of two failure modes. The first is the résumé copy — a direct paste of the professional summary, sometimes with minor edits. The second is the blank field — left empty because the candidate did not know what to write.

Both approaches miss the purpose of the About section entirely. LinkedIn is not a résumé repository. It is a professional platform that people visit to understand who you are, what you do, and whether you are worth reaching out to. The About section is where that case gets made — and for technical professionals, it is almost universally underutilized.

Why the Résumé Copy Does Not Work

A professional summary on a résumé is written for a specific purpose: to position the candidate quickly for a hiring manager doing an initial review under time pressure. It is dense, formal, keyword-forward, and written in third person or implied first person. It is optimized for a six-second scan.

The LinkedIn About section is read in a completely different context. A recruiter who clicked on your profile is already interested. A hiring manager who found you through LinkedIn search wants to know more about you before deciding whether to reach out. A potential client or collaborator is evaluating whether you are credible and worth a conversation.

The About section has 2,600 characters of space. Only the first 220 or so are visible before the reader clicks “see more.” The opening lines need to be compelling enough to earn that click — which a formal, dense résumé summary rarely is.

First Person vs. Third Person

Most style guides for professional writing recommend third person for formal documents. LinkedIn is not a formal document. It is a platform built around professional connection and conversation.

First person — “I build analytics infrastructure” rather than “Data engineer with five years of experience building analytics infrastructure” — reads as more direct, more human, and more confident. Third person on LinkedIn often feels stiff and slightly self-promotional in the wrong way, like reading a press release about yourself.

There are exceptions. Some very senior executives and public-facing professionals use third person effectively because it matches the formal register of their industry or personal brand. But for most technical professionals at any level, first person produces a stronger, more readable About section.

The Three-Part Narrative Structure

A well-constructed LinkedIn About section for a technical professional answers three questions in order: who you are, what you do and what you have built, and who you are looking for or what you are open to.

Part 1: Identity and positioning. Open with a clear statement of who you are professionally and what you are known for. Not a job title — a characterization. “I turn operational data into decisions” or “I build the analytics infrastructure that helps product teams stop guessing” is more compelling than “Senior Data Analyst at HealthMetrics.” The title is already visible elsewhere on the profile. Use the About section to say something the title cannot.

Part 2: The body of evidence. This is where you describe the work at a slightly higher altitude than a résumé bullet. Not a list of every system you have touched, but the two or three most compelling things about your career — the scale of work you have done, the problems you have solved, the impact you have had. This section can include metrics, but it should read as narrative rather than a bulleted list.

Part 3: The forward signal. Close with a clear statement of what you are looking for, what kinds of opportunities interest you, or what you are open to. This is the most commonly omitted section. Without it, a recruiter reading your About section does not know whether you are actively looking, passively open, or not interested at all. A simple sentence — “I am interested in analytics leadership roles at product-driven companies where data is a first-class function” — dramatically increases the likelihood that the right people reach out.

Keywords and Search Visibility

LinkedIn search is keyword-driven. Recruiters and hiring managers searching for candidates with specific skills, titles, or experience types rely on LinkedIn’s search algorithm to surface relevant profiles. The About section is one of the fields LinkedIn indexes for search.

Keywords in the About section should be woven in naturally rather than listed. “I have spent the last four years building SQL-based reporting infrastructure and Tableau dashboards for cross-functional teams” integrates SQL and Tableau into a readable sentence while making both terms searchable. A bullet list of tools at the end of the About section is less readable and no more effective for search.

For technical professionals, the most important keywords to include are: your core technical stack, the type of role you hold or are targeting, the industry you work in, and any specializations or frameworks that distinguish your profile. For senior professionals, leadership and strategy terms matter as much as technical ones.

Senior vs. Early-Career Structures

The three-part structure applies at every career level, but the content and tone differ meaningfully.

Early-career professionals should lean into forward positioning — where they are headed, what they are building toward, what they bring that is differentiated from other candidates at their level. Certifications, projects, and specific technical strengths deserve more space here than they would in a senior profile. The goal is to establish credibility and signal direction.

Senior professionals should lead with impact and strategic identity rather than tools and tasks. The About section for a principal engineer, analytics director, or head of data should communicate organizational influence, strategic thinking, and leadership narrative. Specific tools matter less than the altitude at which the work happened and the scale of decisions it supported.

At both levels, the About section should feel like it was written by a real person for a real reader — not generated, not copied from a template, and not pasted from a document that was written for a different purpose.
