How we know

It hasn't been reposted, listed twice, or left up unusually long, and the posting doesn't say it's a talent pool.

Ghostless records the day it first sees a posting, so a repost can't reset its age. This one was already up when Ghostless started tracking Signicat, so its true age is longer.

Last checked Oct 31, 2026.

What it asks of you

3+ years of experience
“3+ years of experience using Kotlin and/or Java 8+ to develop web applications” (quoted from the posting)
Bachelor's degree asked for

What the posting discloses

Not stated: Pay, real vacancy, AI screening.

Why these three

Ontario requires postings from employers with 25 or more staff to state the pay, whether the vacancy exists, and whether AI screens applicants.

Some employers add pay only on their own site. Check the original posting before you rule it out.
