Top engineers skip JDs that list every technology, promise a "fast-paced environment" and say nothing about the actual problem. JDs that attract strong candidates describe the problem, the current system, what the first 90 days look like and the compensation band.
The mistakes that cost you candidates
These patterns make strong engineers move on:
- A technology list with fifteen items, so no one knows what matters.
- Generic phrases such as "rockstar", "ninja" or "fast-paced environment".
- No description of the product, users or technical challenge.
- Unrealistic requirements, such as ten years of experience in a three-year-old technology.
- No compensation information.
What strong engineers look for
Experienced engineers read a JD to answer a few questions: what will I build, how interesting is the problem, who will I work with, and is it worth my time? A JD that answers these clearly outperforms one that is longer but vaguer.
A structure that works
Use this structure for engineering JDs:
- The problem: one paragraph on what the team is building and why it matters.
- The current state: stack, scale and the biggest open challenges.
- The first 90 days: what the person will own and deliver.
- Must-haves: three to five, genuinely required.
- Nice-to-haves: clearly marked as optional.
- Compensation band and working model.
A rewrite example
Before: "We are looking for a rockstar backend engineer with experience in Java, Python, Go, Kafka, Redis, AWS, Docker and Kubernetes to join our fast-paced team."
After: "We process a large volume of UPI payments a day, and our reconciliation service is the bottleneck. You will own its redesign: moving from nightly batches to near-real-time streaming on Kafka. You need strong Java or Go and experience with high-volume data pipelines."
Frequently asked questions
How do I write a job description for software engineers?
Describe the problem, the current system, the first 90 days, three to five real must-haves, and the compensation band.
Should I include salary in the job description?
Including a band attracts more serious applicants and saves time for both sides.
How long should a JD be?
Long enough to explain the problem and expectations clearly. Clarity matters more than length.
