How to write a Job Description

How to write a job description sounds simple until you are the one trying to do it. You may know the role well, but turning that knowledge into a clear document can be harder than expected.

Maybe the role has grown over time. Maybe the last job description is out of date. Maybe the person doing the job has left, and half of what they did was never written down properly.

That is where a good job description helps. It gives structure to the role before you start hiring. It explains what the job exists to do, where it sits in the business, what the person is responsible for, and what skills or experience are genuinely needed.

A job description is not there to sell the role. That is the job ad. The job description is the working document behind the role, and when it is clear, the whole hiring process becomes easier. If you are starting from a blank page, start here.

Job description basics

Before you write the detail, get the simple facts down. Include the position title, who the role reports to, employment type, location, team or department, and whether the person has any direct reports. These details might seem obvious, but they matter. They show where the role fits and who is responsible for managing it.

Keep the position title clear. Use a title people understand. If the role is mainly administration, call it Administration Officer, Administration Coordinator or Office Administrator, depending on the level. Avoid internal titles that only make sense inside your business.

Define why the role exists

This is the part many people skip. Before listing tasks, write a short role purpose. One paragraph is usually enough.

Ask yourself what this person is here to take care of, what problem the role solves, and what part of the business should run better because this person is in the role.

For example, an Operations Manager role might exist to keep the office, warehouse and workshop running smoothly, manage staff across different areas, improve day-to-day efficiency, oversee stock and supply chain activity, and maintain safe work practices. That gives the role shape. It tells the reader what the job is really about before they get into the detail.

Turn messy notes into a proper job description

Most people do not start with a neat job description. They start with rough notes. That is fine. The job is to sort those notes into a structure that makes sense.

For example, your rough notes for an Office Administrator might look like this:

Rough notes: Answers phones, does emails, orders supplies, helps with invoices, talks to suppliers, updates spreadsheets, books meetings, helps customers, follows up deliveries, keeps office tidy, helps the manager, uses Xero sometimes, does filing, helps with onboarding, organises repairs, handles visitor enquiries. That is not a job description yet. It is a brain dump. The next step is to group the work into responsibility areas.

• Administration: Manage day-to-day office administration, including phone calls, emails, visitor enquiries, office supplies, filing, meeting bookings and general office coordination.
• Accounts support: Assist with basic accounts administration, including invoice processing, purchase orders, supplier follow-up and record keeping in Xero.
• Customer and supplier support: Respond to customer and supplier enquiries, follow up deliveries, provide updates and escalate issues when needed.
• Office coordination: Coordinate repairs, maintain office supplies, support onboarding tasks and help keep the workplace organised.

That version is clearer because it does not list every tiny task as if they are all equally important. It groups the work by purpose. It also gives you headings you can use in the final job description.

Do not write down every tiny task

A job description should be specific, but it does not need to capture every single thing the person may ever do. It is not a training manual.

If someone occasionally orders milk for the kitchen, that probably does not need its own line. If they are responsible for office supplies, repairs, supplier coordination and keeping the workplace running, that does.

A good test is to ask whether the responsibility would matter when hiring, onboarding or reviewing performance. The aim is not to create a document nobody reads. The aim is to create something clear enough to use.

Separate must-haves from nice-to-haves

This section matters more than people realise. It is easy to list everything you would ideally like in a person. The problem is that the list can quickly become unrealistic. A requirement is essential if the person cannot safely or effectively do the role without it, and you cannot reasonably train it in the first few months. If it can be taught, supported or learned on the job, it is probably not essential.

For example, a forklift licence may be essential for a warehouse role if the person needs to operate equipment from day one. Experience with your exact CRM may be nice-to-have if someone with similar system experience could learn it quickly.

Start with what is genuinely needed. That might include experience in a similar role, ability to use Xero, strong Microsoft Office skills, accounts administration experience, customer service skills, attention to detail, or the ability to organise competing priorities.

Include the details people often forget

Some of the most useful parts of a job description are the practical details that get missed when people are rushing.

Think about tools, systems, licences, approvals and working conditions. Does the person need to use Xero, a CRM, inventory software or scheduling tools? Do they need a driver licence, forklift licence or industry certification? Will they approve purchases, issue refunds, manage suppliers or roster staff? Are there physical requirements, travel requirements or safety obligations? Do they need to follow WHS procedures, wear PPE or report hazards?

These details do not need to be dramatic, but they are often the things that create confusion later if they are not written down.

Keep the language plain

A job description should sound like a useful business document, not a motivational poster.

Avoid vague phrases like “dynamic self-starter”, “fast-paced environment”, “must be passionate”, “wear many hats” and “go-getter attitude”. They do not say much.

Say what you actually mean. Instead of “must thrive under pressure”, you might write “manage competing priorities, communicate early when deadlines are at risk, and follow through on agreed tasks”. Instead of “passionate about customer service”, you might write “provide clear, respectful and timely support to customers by phone and email”.

Plain language makes the role easier to understand. It also makes the document easier to use later.

Check whether the role is realistic

Writing a job description can show you something important: the role may have grown bigger than expected.

This often happens when someone has been in a business for a long time and has collected extra tasks along the way. When they leave, the business tries to replace everything they did with one new person.

Sometimes that works. Sometimes it does not.

Once you have written the responsibilities, step back and ask whether this is one role or two, whether it can be done in the hours available, whether the salary matches the level of responsibility, whether the person will have the authority to do what you are asking, and what support they will need.

This is not about making the role smaller for the sake of it. It is about being honest before you hire.

Use the job description beyond recruitment

A good job description gives you a reference point before, during and after hiring. It can shape the job ad, help your recruiter understand the role, guide interview questions, and give the new employee a clearer start.

It is also useful later, when you are checking in during probation, talking about workload, or reviewing performance. Instead of relying on memory or assumptions, both the manager and employee have the same document to come back to. A job description template can help with the structure, but the detail still needs to reflect the real role in your business.

Final check

Before you call it finished, read the job description once more and check:

1. Is the role purpose clear?
2. Are the responsibilities grouped in a way that makes sense?
3. Are the essential skills actually essential?
4. Have you included the key systems, licences, safety requirements, reporting line and realistic scope of the role?

If the answer is yes, you have a job description you can work with.

Getting the role right

Writing a clear job description is the first step. The harder part often comes next: making sure the role is positioned correctly in your business, the salary is competitive for what you’re asking, and you have the structure in place to support the person in it.
