What you'll learn
See what changes from senior to staff to principal
Senior delivers hard projects. Staff finds and scopes problems across teams. Principal sets direction for the org.
Find a staff-sized problem instead of waiting for one
Spot the cross-team problem nobody owns, scope it, and write it up so leaders want it solved.
Use writing as your leverage
Strategy docs, one-page proposals, and reviews are how senior ICs move work they do not own.
Multiply other people's work with AI
Reusable tools, standards, and AI workflows the whole team uses count as staff-level impact.
Why this topic matters
Most senior data scientists try to reach staff by doing senior work harder: more projects, harder models, longer hours. Staff is a different job. It is judged on scope you found, direction you set, and how much better other people's work got because of you. This session maps the senior, staff, and principal expectations, the common shapes a staff role takes, and how to build evidence for the next rung.
