Data Engineering

ML Engineering

You architect systems that turn raw data into intelligent decisions at enterprise scale. This path breeds technical leaders who speak both machine learning and business strategy fluently.

L1 – L9 · 9 tours Leads to: CDO → What's a Reference DRS?

The Career Arc

Rotational · L1–L3

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

  • L1 : Learn ML engineering through model deployment
  • L2 : Deploy and maintain ML models
  • L3 : Own ML systems with strong MLOps practices

Transformational · L4–L7

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

  • L4 : Lead ML projects and mentor others
  • L5 : Drive ML architecture across the org
  • L6 : Set ML engineering direction
  • L7 : Shape the company's ML vision

Manage a Team?

Great ML Engineering 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 ML Engineering chair — build institutions, not just products.

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