Active role records, by age
These figures use X-energy's records marked active, excluding likely evergreen listings. Undated records count as active but do not contribute to posting ages. Role observations may be incomplete; these are not hiring or time-to-fill measures.
Historical records by posting-date cutoff
Includes active and inactive records with employer posting dates on or after each cutoff, excluding likely evergreen listings. These are historical date totals, not current openings or first appearances. Dates have no upper cutoff, so future-dated records can be included.
Historical records by posting month
Active and inactive records grouped by employer posting month; undated and likely evergreen records are excluded. Muted bars predate tracking (July 23, 2026) and include only records later observed.
Recorded appearance and removal events
Events recorded by the tracker, grouped by event month. These are not posting-date totals or a count of current openings; one role can have multiple events. Reappearance events are not included in these totals. The event history may be incomplete.

109 active role records
These records update separately from the snapshot figures above and may include an incomplete collection. Counts can also differ because the snapshot's listed-role count excludes likely evergreen listings and can retain roles since marked removed. Individual posting ages use employer-supplied dates only; records without one show “Posting date unavailable.” Listing age and Newest use those dates too: records without one are listed last and aren't in any age group, and age groups leave out continuous-hiring and evergreen postings, because they stay listed by design.
