Location: North York, Toronto

Duration: 01/21/2019-01/24/2021

Rate: $40/


General Mission:

To perform system design, signalling design, network design, analysis, modelling and simulation to specify communication based train control systems. To develop and define system design features to meet Customer requirements. To analyse and evaluate designs to verify compliance with system technical requirements.  To develop and define Subsystems requirements.  To develop block design, interlocking control tables, and application database for Software subsystems. To analyse and evaluate system performance and prepare associated technical contract deliverable. To design and configure communication networks meeting customer and industry requirements for throughput and security.


The incumbent is accountable for performing the design work correctly, within cost and schedule limits, as defined in approved work packages.  The work is typically defined by the Work Package Manager, then reviewed, modified and agreed with and approved by the Systems Architect and/or Manager.  The System Engineer typically works with a team of engineers to define what will be designed, how it will perform and how it will be determined that it is working correctly.


Key Accountabilities:



  • Converts Customer (internal and/or external) requirements into conceptual designs and prepares associated documentation by performing operational analyses, simulations and technical trade-off studies evaluating alternative design configurations and functional features.
  • Similarly creates new concepts or modifies existing concepts to fulfil customer requirements.
  • Prepares system, subsystem, and interface requirement specifications by analysing, decomposing modelling and refining customer requirements and typical train control domain requirements.
  • Prepares Operational Concept Document.
  • Performs technical/engineering tasks to define system design, subsystem requirements, application databases for software subsystems.  Analysis and simulations are performed as necessary to identify design feasibility & driving requirements.
  • Prepares specialised signalling design skills, covering one or more of the following:
  • Signaling Principles;
  • Block design;
  • Interlocking control tables;
  • Safe braking model;
  • Performance analysis and Headway simulations;
  • Application database design;
  • Prepares specialised network design skills, covering one or more of the following:
  • Communication network requirements;
  • Communication network design (both wired and wireless);
  • Communication network configuration (both wired and wireless);
  • Communication network analysis on various perspectives, such as reliability, security, scalability, maintainability etc.
  • Troubleshooting various complex network issues;
  • Evaluation of existing third-party communication network design and their interaction with CBTC communication network, such as development of interface definition, RF interference, security assessment etc.
  • Prepares and supports bids and proposals, including customer requirements compliance assessment, gap analysis, architecture design, simulation, trade-off of key features, estimation, etc.
  • Presents technical design and reports to customers and/or other engineering/management groups in clear, complete, concise and non-ambiguous terms.
  • Defines or proposes updates of processes and standards covering the work and its products based on the knowledge of systems engineering and/or his technical speciality.
  • Operational design limits are evaluated and defined; performance analyses and simulations are developed & performed to support the above.
  • Ensure the signaling design is implemented in accordance with applicable standards and signaling principles.
  • Interface and build strong working relationships with Software, Hardware and IVVQ groups to ensure timely analysis and resolution of in-house and field test issue.
  • (LR8 or LR9) leading technical discussions, technical solution presentation to internal and external stakeholders


·        Supervises contractors and other systems specialists, by defining their work, coaching them on how and what to prepare, monitoring their progress and directing them on priorities.
