Depth in the services you own, breadth across the systems they talk to.
Backend engineering rewards depth — the person who actually understands why an endpoint is slow, or why a workflow double-writes under retry, is the one who gets pulled into every incident. But pure depth without breadth stalls at senior: these example goals pair concrete backend depth with just enough cross-team exposure to keep growing.

Slow endpoints quietly erode conversion and inflate infra spend, and most teams never actually profile them — they just add more compute. Finding and fixing the real bottleneck is one of the highest-leverage things a backend engineer can do in a quarter.
Reduce P95 latency on the 3 highest-traffic endpoints from 600ms to under 200ms.
Most production incidents in distributed backends trace back to non-idempotent writes and unhandled retries. Owning one such workflow end-to-end — including the failure modes — builds exactly the judgment senior backend roles are hired for.
Ship one production workflow (e.g. order processing or a payment webhook) with idempotency keys and zero duplicate-write incidents for 30 days.
Backend engineers who understand how their APIs are actually consumed, and how their services get deployed, make fewer breaking changes and give feedback that lands.
