Data Engineering

Data Science

You'll build predictive models that reshape business strategy, then scale teams who turn algorithms into competitive advantages. This path creates CDOs who speak both machine learning and boardroom fluently.

The Career Arc

Rotational · L1–L3

Build the Data Science craft. Prove you can wield the tools of Data Engineering.

  • L1 : Learn data science through analysis projects
  • L2 : Conduct analyses that inform decisions
  • L3 : Own analytical domains with statistical rigor

Transformational · L4–L7

Deliver Data Science outcomes — each Data Engineering tour at this altitude has a defined mission and success criteria.

  • L4 : Lead data science projects and mentor others
  • L5 : Drive data science practices across the org
  • L6 : Set data science direction company-wide
  • L7 : Shape the company's data science vision

Manage a Team?

Great Data Science managers are practitioners first. The Data Engineering IC responsibilities in L4–L7 are your foundation — your management responsibilities are additive:

  • Hire people you'd trust locked in a room—skills matter, but trust matters more
  • Build a team that balances technical depth with business curiosity
  • Run 1:1s that connect data work to business impact—not just sprint tickets
  • Give feedback that builds both technical and communication skills
  • Remove blockers—fight for data access, compute resources, and stakeholder clarity

Foundational · L8–L9

Shape the Data Engineering organization from the Data Science chair — build institutions, not just products.

  • L8 : Build and lead data science teams
  • L9 : Own data science strategy and execution
→ C-Suite: L10 is the CDO path — a distinct page, not duplicated here.
