Job Summary

The role of Expert RAM is to provide technical leadership for the RAM discipline in support of the Operational Technology (OT) solutions.

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

These corrective action programs frequently involved working with vendors of products used in the CN solutions.With the advent of Cloud Computing there is also a need for a RAM specialist that is well versed in Cloud based technologies as well as solutions architectures for the cloud.

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

The Expert RAM will also be required to engage with other railroad technical teams, and industry organisations such as Transportation Technology Center Inc.

TTCI) and regulatory organizations such as the Federal Railroad Administration (FRA). As such excellent communication skills are required to represent CN’s interests and influence direction at the industry level.

This position requires a high degree of accountability and initiative.

Main Responsibilities

OT Solution RAM Assessments

  • Review and approve solution requirements for RAM
  • Determine non-functional requirements and targets for RAM performance
  • Perform analysis and modeling to predict RAM behaviour
  • Adhere to the OT system engineering development process

Solution RAM Field Performance

  • Determine which RAM Key Performance Indicators (KPI’s) are appropriate for the solution or product. Determine how to measure these KPI’s.
  • Assign requirements to solutions and products to ensure they support the ability to measure these KPI’s
  • Use the field performance measurement to identify key contributors and drive corrective action plans when necessary

Vendor Product RAM Assessments

  • Review vendor specifications, test results, analysis artifacts
  • Contribute to failure review board for selected vendors
  • Review corrective action plans from the vendors
  • Drive to completion the vendor corrective action plans

RAM Methodology Innovation
