How to write a job description
A well-written job description is the foundation required to build a solid job posting. It allows you to find the right candidate—one whose expectations have been met rather than one who quickly becomes disillusioned with the job.
A job description can also offer clarity to current employees whose jobs have been redefined. Communicating new roles in clear terms can avoid task duplication and the possible overstepping of responsibilities.
BDC Senior Business Advisor Émilie Poirier helps respond to requests from businesses that don’t have a human resources department. She often meets with a general manager or supervisor to help write job descriptions.
“We go in, sit down, and review all the job descriptions. Then, we work together to ensure the structure is well defined,” she says. This includes looking at organigrams, focusing first on roles and responsibilities, and then on accountability.
“We make sure the existing job descriptions are properly written and updated and that we understand what they do.”
Writing job descriptions
Poirier says that whether it’s for recruiting, performance, or talent development, you need to involve your employees in writing job descriptions. She says employees often find themselves with new duties and workloads, necessitating a rewrite of their job description.
“It’s an opportunity to communicate with them and understand what they’re doing,” she says. “We encourage employees to come forward if they notice their job evolving.”
“And my advice to managers is to ask their employees questions so that they understand that you know who they’re accountable to, as well as their roles and responsibilities,” she says, adding that this avoids duplication of tasks.
8 tips for writing good job descriptions
Writing effective job descriptions that set clear expectations is crucial for attracting qualified candidates and retaining employees. Keep in mind these tips when creating job descriptions:
1. Use clear language
Write concise and straightforward descriptions. Avoid jargon or overly complex terms. Candidates should easily understand what the role entails.
2. Maintain a positive tone
Job descriptions reflect your company’s culture. Use positive language to convey enthusiasm about the role and organization.
3. Be descriptive
Provide a snapshot of day-to-day tasks. Highlight key responsibilities, skills required, and the role’s contribution to your company’s mission and goals.
4. Keep a tight format
Organize responsibilities in bullet points or short paragraphs. Make it easy to read, but also easy to scan.
5. Showcase the position
Explain the impact the role has within the organization and how it contributes to overall success.
6. Promote the company
Briefly mention your company’s mission, culture, and benefits. This helps candidates understand your organization better.
7. Create realistic expectations
Be transparent about challenges and requirements. Set expectations that align with the role.
8. Highlight growth and development
Mention opportunities for learning, skill development and possible career advancement.
Roles and responsibilities
Poirier says if you want to write a good job description, it comes down to figuring out the role and responsibility of the employee—their title and what they do.
“Start thinking about the person you’re trying to attract and then write down a job description, making sure the roles and responsibilities are clear for that role.”
She says putting together , which explain the work an employee is expected to perform, can avoid overstepping authority and confusion over who does what at an organization.
“One person says, ‘I’m doing this’, and another says, ‘No, I’m doing that.’ Or there’s a job that’s at a lower pay grade, but the person is doing the work of a higher pay grade. That’s why it’s super important to maintain and make sure roles and responsibilities are up to date,” Poirier says.
Sometimes the roles and responsibilities get defined after a job has been split up.
“When I was a partner in a smaller mid-sized company, there was a controller who had too much on his shoulders. So, we talked to him about hiring a technician to help him out.”
We wrote down the controller role and figured out which responsibilities could be transferred to the new technician role.
“That really opened up communications around roles and responsibilities.”
Employees want to be heard, and the development of a job description is a perfect opportunity to increase their involvement.
