Start from the work, not a template. Write what the person will actually do, what they will not be expected to do, the one primary skill, the secondary skills, and what good looks like after six months. A focused description attracts fewer but better applicants, and it gives screening tools a clear brief to match against.
Why do so many job descriptions miss?
Many companies write a JD by copying another company's. Some are so similar you cannot tell who copied whom. Others are so complicated nobody can tell who the role is for.
The traditional JD was a formal document for job boards and compliance. Over the years it became a copy-paste artifact that tells a candidate little about the actual work.
What is the superman problem?
Every hiring manager wants someone who can play goalkeeper, defender, midfielder and striker at once, and the JD lists all eleven positions.
Software testing JDs that ask for exploratory testing, automation, performance, security and DevOps in a single role are easy to find. You get what you ask for. Ask for confusion, and confused applicants apply.
How do you write a better one?
Start with rough notes. What do you need this person to do? What are you not asking them to do? What does good look like six months in?
Then turn the notes into a clear JD, by hand or with an AI assistant. GetHirePlus has a Build My JD feature that does this from your inputs. A precise JD also improves AI resume screening, because the system has clear criteria to compare resumes against. See How Do You Screen 500 Resumes Without Reading All 500?
When you reach the offer stage, the offer letter generator keeps the terms consistent with the role you described.
