Definition

The job description is a fundamental HR document that details all information relating to a role: title, key responsibilities, technical and behavioural skills expected, working conditions, remuneration and benefits. It serves both as a recruitment tool (basis for the job posting) and internal reference (assessment, mobility, workforce planning).

Typical structure of an effective job description

Essential Sections

SectionContentCommon Mistake
Job TitleClear, market standard titleFanciful title not searched for
Company OverviewMission, culture, size, sector (3–5 lines)Too long or overly corporate
Key Responsibilities5 to 8 concrete and prioritised responsibilitiesEndless list of 20+ points
Required SkillsHard + soft skills, separate essential from desiredUnrealistic profile with too many requirements
Conditions and BenefitsSalary, remote work, hours, benefitsNo mention of remuneration
Recruitment ProcessSteps, timelines, contact peopleMissing from 70% of job descriptions

Write an inclusive and attractive job description

Quality checks before publishing

  • Neutral and inclusive language

    Avoid gendered or exclusionary phrasing ("young and dynamic")

  • Maximum 6 essential skills

    Beyond that, women and minorities apply less

  • Salary range displayed

    Increasingly required and a major attractiveness lever

  • Concrete action verbs

    "Manage", "Design", "Coordinate" rather than "Be responsible for"

  • Scannable format (bullets, headings)

    Candidates spend 14 seconds on average scanning a listing

  1. 1

    Interview the operational manager

    Understand the real stakes of the role, priorities for the first 6 months and truly essential skills.

  2. 2

    Benchmark competitor postings

    Analyse 5 to 10 similar listings to identify market standards and your differentiation points.

  3. 3

    Write from the candidate perspective

    Answer the questions candidates ask: "What will I do? With whom? In what environment? For what salary?"

  4. 4

    Have a peer review

    Someone in that role can validate relevance and correct recruiter blind spots.

What is the difference between job description and job specification?
The job description is recruitment-focused (attractive, sales-oriented) whilst the job specification is an internal document more detailed (reporting line, evaluation criteria, career progression). The job description is often an edited-down version of the job specification.
Should I include the salary in the job description?
Yes, highly recommended. Studies show listings with salary ranges generate 40% more applications and attract better-aligned profiles. The European wage transparency directive will progressively make this mandatory.
What is the ideal length for a job description?
500 to 700 words. Below that, candidates lack information. Beyond 1,000 words, application rates drop significantly. Prioritise concision with bullets and clear structure.
