Role	Required	Description
Systems Programmer (C/C++)		Understands the fundamentals of Real-Time Programming. Applies basic practices in daily work. Follows recommendations from the team and documentation.

Role	Required	Description
Systems Programmer (C/C++)		Develops real-time components: uses PREEMPT_RT, configures SCHED_FIFO/SCHED_DEADLINE, memory locking via mlockall. Measures and minimizes worst-case latency.

Role	Required	Description
Systems Programmer (C/C++)		Designs hard real-time systems: formal timing analysis, priority ceiling protocol, bounded execution time. Implements deterministic memory allocation, eliminates non-determinism sources.

Role	Required	Description
Systems Programmer (C/C++)		Defines real-time architecture for the product platform. Establishes timing verification standards, manages real-time budgets, conducts compliance reviews for timing requirements.

Role	Required	Description
Systems Programmer (C/C++)		Shapes enterprise real-time strategy for the organization. Defines approaches to real-time system certification (DO-178C, IEC 61508), mentors leads on formal timing analysis.
