Writing a position description that actually helps you hire

By Workforce Pathway Australia

A position description is often treated as a formality — something you copy from an old file and never look at again. That is a missed opportunity. A well-written position description is the foundation your whole hiring process stands on: it shapes your advertisement, it gives you a fair yardstick for comparing candidates, and it sets clear expectations from day one. Here is how to write one that earns its keep.

What a position description is for

At its simplest, a position description sets out what the role is, what the person will do, and what they need to do it well. But its real value is what it enables afterwards. A clear description makes your job ad easier to write, gives every interviewer the same reference point, helps you compare candidates against the same standard rather than gut feel, and gives the successful person a clear picture of what is expected. Get the description right and the rest of the process gets noticeably easier.

The structure that works

You do not need anything fancy. A strong, reusable position description usually includes:

• Job title and reporting line. The plain title, who the role reports to, and where it sits.
• Purpose of the role. Two or three sentences on why the job exists and what it is there to achieve.
• Key duties and responsibilities. The main tasks, written as a clear list rather than a wall of text.
• Essential requirements. The skills, experience, qualifications, licences or tickets a person genuinely cannot do the job without.
• Desirable requirements. The extras that would help but can be learned on the job.
• Working conditions. Location, hours, type of employment, and anything physical or practical the role involves.

Write duties people can picture

The duties section is where a position description either comes alive or falls flat. Aim for clear, active descriptions of what the person will actually do — "prepare and finish surfaces to specification" rather than "responsible for quality outcomes". Group related tasks together, list them roughly in order of importance, and keep the total manageable. Six to ten well-chosen duties beat a list of twenty vague ones. When the duties are concrete, candidates can honestly judge whether the role suits them, and you can assess each applicant against the same clear list.

Be honest and realistic about requirements

The single most common mistake is an overloaded requirements list. When everything is marked essential, two things happen: strong candidates who lack one minor item do not apply, and you lose the ability to tell what genuinely matters. Be disciplined. Put only true deal-breakers under essential, and move everything else to desirable. A short, honest essential list widens your pool of good applicants and makes shortlisting far simpler, because you are measuring everyone against the same handful of must-haves.

Keep it current and reuse it

A position description is most valuable when it reflects the role as it actually is today, not as it was three years ago. Before you advertise, read it through and update anything that has changed — duties, tools, reporting lines, conditions. Once it is accurate, it becomes a reusable asset: the basis for your job ad, your interview questions, and the expectations you set with the new starter. A small amount of effort here pays off at every later stage of hiring.

Where this fits in your hiring

Think of the position description as the source document for the whole process. Your advertisement is a shorter, more appealing version of it. Your interview questions test the requirements it lists. Your shortlisting compares candidates against it. When the description is clear and current, everything downstream lines up — and that consistency is exactly the kind of groundwork we help employers put in place, so each hire starts from a solid, well-written foundation.
