How to cite
New Nuclear Jobs, Advanced nuclear open roles (daily), https://newnuclearjobs.com/data/, accessed 10 Nov 2026. CC BY 4.0.
In a sentence: "according to New Nuclear Jobs, which counts open roles on the job boards of 21 advanced nuclear companies each day". Please link to this page so readers can check the numbers.
Method
- Every day at about 06:20 UTC we read the public job boards (Greenhouse, Ashby and Lever) of the advanced nuclear employers listed in the company table and count the roles each one lists.
- "Open roles" is the number of postings on the employer's own board that day. We leave out general-application and talent-pool postings (titles such as "General application"). One posting can name several places.
- "Posted" is the date the employer's board gives for the posting (first published or created, depending on the board). It is not the date the job was filled or closed.
- "Days since posted" describes roles that are still open. It is not time-to-fill: roles that were filled quickly have already left the data.
- Role families come from keywords in the job title (the department when the title has none). States come from the location text; a role that names two states counts in each.
- A day on which any employer's board does not answer has no row. We never record a failed read as zero.
- When we add an employer, the column employers_tracked changes. Treat a jump on that day as a change in coverage, not in hiring.
- Coverage: venture-backed and private advanced reactor, microreactor, fuel and services companies whose boards are public. Large vendors and utilities whose boards we cannot read (for example X-energy, NuScale, Holtec, Westinghouse, GE Vernova) are not included, so these are not totals for the nuclear industry.
Each count can be checked: every company page here links to that employer's own board, and every role links to the employer's posting.
What these numbers do not say
- They are not totals for the nuclear industry, and not hiring at utilities, national labs or the NRC.
- An open posting is not a hire. One posting can cover several hires.
- Days since posted is not time-to-fill, and we publish no ranking of employers by it.
