The role of Specialist Train Control System Design is to ensure production of detailed functional design for solution subsystem components, whether based on a packaged solution or on custom development. This involves working with Product Management, Architecture and end users to understand the End-to-End Architecture and requirements and flesh out a detailed system design for the specific component or area of expertise. This includes working with the Expert Train Control System Design to ensure consistency and practices based approach across the entire subsystem design. They will also be involve in the development, testing, and integration stages.


System Design

  • Analyze sub-system component issues and/or business requirements to design effective, high-availability, business-critical solutions
  • Will work with the Expert Train Control System Design to understand high-level proposed architecture and transpose it into subsystem designs that will meet all functional and non-functional requirements
  • Follow standard and best practices to ensure the systems design is maintainable, sustainable and properly documented with all the associated IP constructs
  • Follow standards and best practices to ensure reliability, safety and cybersecurity standards are imbedded in the design of the sub systems
  • Work with the Expert Train Control System Design to adopt and enforce System Design best practices
  • Understand rail subsystems architecture in order to develop specifications on technical design aspects (hardware & software integration)
  • Design and propose enhancements and modifications to the subsystem architecture
  • When called upon, will be required to work with FRA and CN personnel in the various regulatory inspections to ensure all requirements are properly designed

Delivery & Quality

  • Work with the development team to ensure system design is fully understood and developed with high quality
  • Identify deployment plan and support Q&A and integration engineers from a technical subsystem product owner perspective
  • Ensure compliance with and oversee development, and execution of testing strategies, test plans, and test procedures to validate that the system correctly implements the specifications
  • Work with quality leads, management, and QA to constantly monitor quality KPI’s and implement design improvements



  • Bachelor’s Degree in Electrical Engineering, Computer Engineering or related field


  • Good oral, written and presentation skills
  • Ability to analyze, design & document detailed designs
  • Knowledge of train control (ATC) & protection (ATP) systems (railway signaling, interlocking, European Train Control System, Positive Train Control, Communication-Based Train Control, etc.)
  • Knowledge of system engineering & design processes (ISO/IEC 15288 & 12207 or equivalent)
  • Knowledge of system engineering modelling and requirements management tools
  • Knowledge of railway safety engineering practices (IEC 61508, EN 50126/IEC 62278, EN 50128/IEC 62279 and EN 50129/IEC 62425) or equivalent from other industries
  • Ability to analyze, design & document detailed designs
  • Ability to provide, verify and validate work estimates
  • Proficient in documentation of complex concepts such as impact analysis, security models, performance and capacity planning, and strategic technical decision


  • Proven track record of success in complex system engineering environments
  • Minimum 5-10 years overall work experience (including in system integration of a complex train control system and in software engineering and design)
  • Minimum 3 years demonstrating technical leadership qualities and/or overseeing deliverables (including in a leadership role of leading developers or integrators)


  • Knowledge of railway freight environments in North America
  • Knowledge of train supervision (ATS) systems (dispatching, movement planning, conflict detection, decision support system, etc.) an asset
  • Knowledge of automatic train operation (ATO) environment, grades of automation and systems an asset
  • Experience in working with Agile and Dev(Sec)Ops development organizations
  • Managing Life cycle of delivery of complex system
