How to Write a Great Job Description

A well-crafted job description attracts the right candidates, sets clear expectations, and reflects your company's culture — before anyone applies.

Why job descriptions matter

A job description is often the first impression a candidate has of your company. It shapes who applies, who self-selects out, and how quickly you fill the role. Done well, it saves your hiring team time by drawing in qualified candidates who understand what the role truly requires.

Good to know: Research consistently shows that job postings with clear, specific requirements receive more relevant applications — and reduce time-to-hire by narrowing the field early.

The anatomy of a strong job description

A well-structured job description covers six core sections, each serving a distinct purpose:

  1. Job title — Use a standard, searchable title. Avoid internal jargon like "Marketing Ninja" or "Customer Happiness Wizard." Candidates search by conventional titles.
  2. Role summary — A 2–4 sentence overview of the position, where it sits in the organization, and the core purpose it serves. This anchors everything that follows.
  3. Responsibilities — A bulleted list of the actual day-to-day work. Aim for 5–8 items. Start each with an action verb (e.g., "Manage," "Design," "Collaborate").
  4. Requirements — Separate must-haves from nice-to-haves. Listing every possible skill as required discourages strong candidates who don't tick every box.
  5. Compensation and benefits — Include a salary range where possible. Transparency here significantly increases application rates and trust.
  6. About the company — A brief, honest description of your mission, culture, and what makes your team worth joining.
Example: role summary

"We're looking for a Senior Product Designer to join our 8-person product team. You'll own end-to-end design for our core mobile experience — from research and wireframes through to polished production assets — working closely with engineering and product management to ship work that reaches millions of users."

Writing with the right language

Language shapes who feels welcome to apply. Vague or overly demanding phrasing — especially around requirements — can unintentionally exclude qualified candidates.

 Avoid: "Must have 10+ years experience in a fast-paced, dynamic environment. Rockstar only. Must be able to wear many hats."

Better: "5+ years of experience managing cross-functional projects. Comfortable shifting priorities in a growing startup environment."

 A few practical rules for language:

  • Use plain, direct language. Short sentences. Active voice.
  • Avoid gendered or coded language (e.g., "aggressive," "dominant," "nurturing") — these subtly signal who belongs.
  • Be specific about skills. "Strong communicator" means nothing; "comfortable presenting to C-suite stakeholders" does.
  • Use "you will" and "you'll" rather than "the candidate must" — it creates a more direct, inviting tone.
  • Limit the use of acronyms and internal terminology.

Watch out: "Must have a degree" shuts out capable candidates who learned through experience. Only list education requirements if they are genuinely essential for the role (e.g., regulated professions).

Common mistakes to avoid

Requirement overload
Listing 20+ requirements — many of which are nice-to-haves — leads to fewer applications overall, particularly from women and underrepresented groups who tend to apply only when they meet a higher percentage of criteria.

Keep requirements to 6–8 core items. Move everything else to a "Nice to have" section or cut it entirely.

Vague responsibilities

Too vague: "You will be responsible for various marketing activities."

Much better: Plan and execute monthly email campaigns, manage our social media calendar, and report on channel performance weekly."

Missing the basics

Many postings leave out location, work model (remote/hybrid/on-site), and salary. These are among the first things candidates look for — and omitting them increases bounce rates on job postings.

Sample

Here's a high quality sample job description to illustrate the principles.

  • Perform in-process and final inspection using micrometers, calipers, CMM, and surface plates
  • Make offsets and minor program edits to maintain dimensional conformance during production runs
  • Complete first-piece sign-offs and maintain accurate traveler documentation
  • Perform routine machine maintenance (lubrication, chip removal, coolant checks) and report issues promptly

Nice to have:

  • Experience with 5-axis machining or Swiss-type lathes
  • Exposure to AS9100 or ISO 9001 quality systems
  • Familiarity with Mastercam or similar CAM software
  • NIMS or equivalent machining certification
  • Experience machining aluminum, titanium, or Inconel

Final checklist

Before you publish, run through this list:

  • Job title is clear and searchable
  • Role summary explains the purpose and team context
  • Responsibilities use action verbs and are specific
  • Requirements are separated into must-haves and nice-to-haves
  • Language is inclusive and free of jargon or coded terms
  • Salary range, location, and work model are included
  • Company description is brief, honest, and compelling
  • A colleague outside the team has reviewed it for clarity

Pro tip: Ask someone unfamiliar with the role to read your draft. If they can't explain the job back to you in a sentence or two, the description needs more clarity.
