SRE

Masters chaos at scale, turning system failures into competitive advantages through obsessive measurement and automation. Produces CTOs who sleep soundly because they've eliminated the 3 AM pages that haunt other executives.

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

The Career Arc

Rotational · L1–L3

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

  • L1 : Learn SRE fundamentals through operational work
  • L2 : Own reliability for services independently
  • L3 : Drive reliability improvements with strong judgment

Transformational · L4–L7

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

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

Manage a Team?

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

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