First 90 Days

Tailor your ramp to level:

• L3–L4: ship small wins weekly; learn the pager; build trust with crisp execution and good questions.
• L5: deliver a meaty feature end-to-end; improve a critical oncall runbook; mentor intentionally.
• L6: land a cross-team design; retire a class of incidents; establish a standard (linting, tracing, SLOs) org-wide.
• L7: align leaders on a technical strategy; sequence a multi-quarter migration; create leverage with a platform or program.

Across all levels: write it down. Clear RFCs are portable proof.
