Software Engineering
Fullstack
Master both frontend elegance and backend architecture to become the CTO who actually understands the entire system. You'll lead through technical depth, not just management theory.
The Career Arc
Rotational · L1–L3
Build the Fullstack craft. Prove you can wield the tools of Software Engineering.
Transformational · L4–L7
Deliver Fullstack outcomes — each Software Engineering tour at this altitude has a defined mission and success criteria.
- L4 : Lead projects across the stack and mentor others
- L5 : Drive architecture decisions across the product
- L6 : Set technical direction across the stack
- L7 : Shape the company's technical vision
Manage a Team?
Great Fullstack 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 Fullstack chair — build institutions, not just products.
