Show trajectory, not just titles
Eightfold's model weights career arc as a first-class signal. A clean progression: IC → senior IC → lead → manager, embeds differently from lateral hops, and the model rewards the upward shape. Write each role's first bullet as a scope-and-promotion signal: "Promoted from Senior Engineer to Staff Engineer in 2024 after leading the Kafka → Kinesis migration that cut infra cost 31%." The trajectory score is invisible to you but visible to the recruiter, it's why two CVs with identical keywords can land at #3 and #47 in the same shortlist.
