Software Engineering

Platform

You'll architect systems that millions depend on, then scale the teams who build them. This path creates CTOs who think in decades, not sprints—technical visionaries who know when to rebuild and when to iterate.

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

The Career Arc

Rotational · L1–L3

Build the Platform craft. Prove you can wield the tools of Software Engineering.

  • L1 : Learn platform engineering through tooling development
  • L2 : Ship platform features that developers adopt
  • L3 : Own platform components with strong DX judgment

Transformational · L4–L7

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

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

Manage a Team?

Great Platform 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 Platform chair — build institutions, not just products.

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

What Hiring Managers Look For

You've built systems that handle real scale—millions of requests, terabytes of data, or complex distributed failures—with metrics to prove it worked.

You've designed infrastructure that other teams actually adopted and can articulate the technical trade-offs that made competing solutions fail in your environment.

You've transformed engineering productivity across multiple teams through platform decisions, with clear before/after metrics on deployment speed, system reliability, or developer velocity.

Common Career Transitions
