7 Tips For Writing Job Descriptions

Most small business owners don’t realize how important job descriptions are until they end up with a bad hire. Writing job descriptions is one of those tasks that feels like a formality, until it isn’t. A weak posting attracts the wrong candidates, creates confusion during onboarding, and can even expose your business to legal risk. The good news is that a few deliberate adjustments can turn your job posting into a far more effective hiring tool.

Let’s get into it.

Why Does a Well-Written Job Description Matter More Than You Think?

A job description is the first filter in your hiring process. It signals to candidates whether the role is worth their time, sets expectations for what success looks like, and gives you documentation to reference if a performance or termination issue ever comes up.

Most small business owners think of a job description as a hiring tool. It’s actually an HR infrastructure tool. It affects recruiting, onboarding, performance management, and legal defensibility, all from a single document.

Can a Bad Job Description Create Legal Risk for Your Business?

Yes, and more easily than you’d expect. Job descriptions that blur the line between essential and non-essential duties, use vague or exclusionary language, or fail to reflect what a role actually requires can create problems if a termination or discrimination claim ever surfaces. The ADA requires that essential functions be clearly identified, and courts have used poorly written job descriptions against employers in wrongful termination cases.

Retaining job descriptions for three to five years after a role changes is a smart practice. Most small businesses skip this step entirely.

What Should Every Job Description Include?

The best job descriptions tend to follow a similar structure. You need a clear job title, a two-to-three sentence role summary, a responsibilities section (broken into essential and non-essential duties), qualification requirements (separated into required versus preferred), and the work arrangement (remote, hybrid, on-site).

Compensation is increasingly expected too, and in several states, it’s required. More on that below.

How Do You Write a Job Description That Actually Attracts the Right Candidates?

Small changes to a job description can have a big impact on the quality of applicants you receive. The seven tips below are practical and specific: each one addresses a real pattern that causes otherwise decent postings to underperform.

Tip 1: Write an Accurate Job Title

Titles like “Marketing Ninja” or “Growth Rockstar” feel creative but perform poorly in search results and confuse candidates trying to gauge fit. Use the title the person would actually search for. If it’s a “Marketing Coordinator,” call it that.

Tip 2: Lead With What You’re Offering, Not What You Want

Most job postings open with a laundry list of candidate requirements. Flip that. Lead with what makes the role and company worth a candidate’s attention: the team, the work, the growth opportunity. Candidates are evaluating you as much as you’re evaluating them.

Tip 3: Separate Essential Duties From Nice-to-Haves

Every job has a short list of functions the person must perform and a longer list of things that would be helpful. Mixing the two buries the lead and sets you up for problems later. Label them clearly. This also matters for ADA compliance: essential functions should be documented, not implied.

Tip 4: Write in Your Actual Company Voice

A job description written in corporate boilerplate sounds like every other posting. If your company is casual, write casually. If you’re more buttoned-up, reflect that. Candidates self-select based on tone, and that’s a good thing. The wrong cultural fit will leave anyway.

Tip 5: Keep It Scannable

Walls of text discourage applications. Use short paragraphs, clear section headers, and concise bullet points for responsibilities and qualifications. Candidates often review postings on a phone, so your formatting needs to accommodate that.

Tip 6: Avoid Over-Filtering With Your Requirements List

Listing 15 required qualifications when you’d genuinely hire someone with eight is a self-defeating move. Research shows that certain candidate groups, especially women, apply less frequently when they don’t meet every listed requirement. Be honest about what’s truly required versus what’s aspirational.

Should You List a Salary Range in a Job Description?

Yes, and not just because it’s legally required in states like California, Colorado, New York, and Washington. Posting a salary range significantly improves application quality. Compensation is one of the most important factors candidates consider when evaluating a role, so providing a salary range helps set clear expectations from the start.

If your range is wide, that’s fine. Give candidates enough information to make a decision before they invest time in the process.

Tip 7: Use Plain, Inclusive Language

Avoid gendered phrasing, unexplained internal jargon, and language that could signal cultural fit in ways that create legal exposure. Tools like Textio or even a second set of eyes can help catch patterns you might not notice. The goal is a posting that communicates clearly to qualified candidates, not one that filters them out before they apply.

How Do You Avoid Accidentally Screening Out Good Candidates?

The most common culprits: requiring a degree when experience would serve equally well, listing years of experience as a proxy for specific skills, and using vague phrases like “fast-paced environment” or “self-starter” without defining what those look like at your company. Be specific about what the role actually demands. Vague requirements tend to screen out great candidates and attract candidates who are good at reading job postings.

What Are the Most Common Job Description Mistakes Small Businesses Make?

A few patterns come up constantly with small business job postings:

Vague or gimmicky titles. Already covered above, but worth repeating because it’s that common.

Copying a template without editing it. Templates are a starting point, not a finish line. If the responsibilities section doesn’t reflect what the role actually requires at your company, candidates will figure that out pretty quickly after you’ve hired them.

Listing 20+ requirements. This signals that no one thought critically about what the role genuinely demands. It also suppresses application volume unnecessarily.

Ignoring ADA-sensitive language. Physical requirements, if genuinely essential, must be documented. But language that goes beyond those requirements without operational justification can become a liability.

Failing to update job descriptions after a role evolves. The job you hired for two years ago probably isn’t the same job you have today. Outdated descriptions create performance management confusion and can complicate termination decisions.

When Should You Get Help Writing and Managing Job Descriptions?

If writing a solid job description feels like one more thing you don’t have time to do well, you’re probably right that it deserves more attention than it’s getting. Job posting best practices take time to implement consistently, and for small business owners managing hiring alongside everything else, that consistency rarely happens.
