Specialist RAM

Job Summary

The role of the Specialist, Reliability-Availability-Maintainability (RAM) is to execute RAM analysis and engineering in support of the I&T solutions.

The overall mandate is to ensure that these solutions have attributes of high robustness, reliability, and availability.

This involves system and product analysis, modeling and requirements assessment during the development phase and the analysis of field RAM data to determine solution RAM KPI’s and to drive corrective action programs.

Separate specializations may exist for hardware and software RAM. The technologies used are primarily distributed digital control systems, communication networks, Global Navigation Satellite Systems (GNSS), embedded and virtualized computing.

The incumbent is expected to collaborate with other rail industry technical teams, industry organizations, such as the Transportation Technology Center Inc.

TTCI), and regulatory agencies, such as the Federal Railroad Administration (FRA). Therefore, excellent communication skills are required to represent CN's interests and influence direction across the industry.

This position requires a high degree of accountability and initiative.
