Rolle	Pflicht	Beschreibung
Systems Programmer (C/C++)		Understands low-latency principles: cache locality, branch prediction, prefetching. Measures latency of simple operations using rdtsc/perf, analyzes jitter under mentor guidance.

Rolle	Pflicht	Beschreibung
Systems Programmer (C/C++)		Designs low-latency components: applies lock-free algorithms, memory pooling, huge pages. Optimizes system calls via bypass (io_uring), configures CPU isolation and pinning.

Rolle	Pflicht	Beschreibung
Systems Programmer (C/C++)		Designs ultra-low-latency systems: kernel bypass (DPDK, SPDK), busy-polling, zero-copy I/O. Optimizes interrupt moderation, NUMA-aware allocation, eliminates jitter sources in kernel.

Rolle	Pflicht	Beschreibung
Systems Programmer (C/C++)		Defines low-latency architecture for the product platform. Establishes performance budgets for each component, conducts reviews for latency requirements compliance.

Rolle	Pflicht	Beschreibung
Systems Programmer (C/C++)		Shapes enterprise low-latency systems strategy. Defines approaches to guaranteed latency SLAs, manages infrastructure for sub-microsecond processing, mentors experts.
