Software Engineering

ML/AI

You'll architect systems that learn and adapt, not just execute code. This path creates CTOs who see patterns in chaos and build organizations that evolve with their data.

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

The Career Arc

Rotational · L1–L3

Build the ML/AI craft. Prove you can wield the tools of Software Engineering.

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

Transformational · L4–L7

Deliver ML/AI outcomes — each Software 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 company-wide
  • L7 : Shape the company's ML vision

Manage a Team?

Great ML/AI managers are practitioners first. The Software Engineering IC responsibilities in L4–L7 are your foundation — your management responsibilities are additive:

  • Run 1:1s for growth, not status—development conversations, not standups
  • Hire engineers who raise the bar—own the interview process end-to-end
  • Give direct feedback with care—it's how people actually improve
  • Remove blockers—shield the team from chaos so they can ship
  • Watch for burnout and team health—intervene before it's a crisis

Foundational · L8–L9

Shape the Software Engineering organization from the ML/AI chair — build institutions, not just products.

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