Most frequently reposted role
“Staff Embedded Software Engineer” has appeared as a new posting 9 times since August 2025.
A role can be reposted for ordinary reasons — multiple openings, a hire that fell through, or continuous hiring for a high-turnover position.
What these numbers can and can’t tell you
Every figure above counts what appeared on Lightmatter’s own careers site. We don’t know when a posting was originally published — only when we first saw it — so every age is a minimum, and the real figure may be higher.
A long-listed posting is not evidence of a fake one. We publish the observation and let you decide what to make of it. Full methodology.
