You get plenty of applications, but rarely the right ones. The cause is often somewhere you'd least suspect: the job description itself. Knowing how to write job descriptions that are precise is the first filter of a successful hire.
The problem is that a vague description attracts off-target profiles and discourages the best ones. A qualified candidate spends three to five minutes on a post before deciding whether to apply. In five minutes, everything is decided. Here's how to write a description that attracts the right candidates and naturally screens out the rest, with no extra sorting on your end.

1. Why Your Post Attracts the Wrong Profiles
A job post is a filter. Well written, it attracts relevant profiles and repels the rest. Badly written, it does the opposite: it buries good candidates under a flood of off-target applications.
The flaws that turn good profiles away:
- a generic title, invisible in candidates' searches
- an endless list of requirements, discouraging the qualified
- corporate jargon that hides the reality of the role
The problem is that a qualified candidate has other offers. Faced with vagueness, they don't apply: they move on to the next one.
2. A Precise, Genuinely Searched Title
The title is the first thing a candidate reads, and often the only thing they see in a list of results. If it doesn't use the terms candidates search for, your post stays invisible.
Best practices for the title:
- use the exact, recognized job title, not an internal invention
- state the seniority level, which alone screens out bad candidates
- append the key technologies and work mode (remote) if relevant
What matters is immediate clarity. "Senior DevOps Engineer - Kubernetes, remote" says more than "Passionate tech talent."
3. The Real Day-to-Day Over Jargon
The heart of the post concretely describes what the hire will do day to day. Tech candidates in particular appreciate clear communication and hate corporate speak.
What a good description shows:
- the real projects the candidate will work on
- the precise tech stack, not "a modern environment"
- the team, the context, and the concrete impact of the role
Write as if you were talking to a colleague. Overly promotional or impersonal descriptions are spotted immediately, and read as a negative signal.
4. Rank Responsibilities, Limit Requirements
The most common mistake is the shopping list: seven languages, five frameworks, ten qualities. It discourages precisely the profiles you're targeting, who never tick every box.
The right structure:
- rank responsibilities by real importance
- clearly separate must-haves from nice-to-haves
- list only the skills genuinely necessary for success
What matters is realism. A tighter post attracts more good candidates than an exhaustive one, because it gives them permission to apply. It's also what engineering managers actually look for: targeted criteria, not an ideal list.
5. Salary, Purpose, and Alignment With Assessment
Three elements finish convincing a good candidate. Salary first: a stated range attracts, its absence drives away. Purpose next: connect the role to a concrete impact on the team and the product.
Finally, alignment with what you'll assess. A precise post sets the criteria your evaluation will then verify. If you announce concrete responsibilities, your technical test must reflect them, not measure disconnected theory.
What matters is end-to-end consistency:
- what the post promises, the interview must deliver
- what the post describes, the assessment must test
- what the candidate will experience, the post must announce
Platforms like Scalyz let you align the technical assessment with the real responsibilities described in the post, which reinforces consistency and candidate trust.
6. FAQ: Writing a Job Description
What attracts a good candidate in a job post?
A precise title, a concrete description of the day-to-day, ranked responsibilities, a salary range, and purpose. The candidate wants to understand in five minutes what they'll do and why.
Should you state the salary in a job post?
Yes. Salary is one of the most looked-at elements. A stated range attracts, while its absence reads as a lack of transparency.
How do you avoid discouraging good candidates?
By limiting requirements to the essential and clearly separating must-haves from nice-to-haves. An endless list drives off precisely the qualified profiles.
How often should you update a job description?
About every six months: remove obsolete requirements and add the technologies you actually use. A dated post attracts mismatched profiles.
Conclusion :
Knowing how to write job descriptions effectively means understanding that a post is the first act of selection, not a mere formality. A precise title, a real day-to-day, realistic requirements, a stated salary: these choices filter good profiles before the first application.
The right question isn't "how do I describe the role?" but "what will make the right candidate want to apply, and the wrong one move on?" A precise post does the sorting for you.
