Your future role

Take on a new challenge and apply your network and cybersecurity knowledge in a cutting-edge field. You’ll work alongside collaborative and innovative teammates.

You'll play a central role in reducing the carbon footprint of Canada's busiest public transit system by contributing to the On-Corridor Works project as part of the ONxpress consortium. Day-to-day, you’ll work closely with teams across the business, including network security design and engineering, assist the Lead System Designer, and support the commissioning of integrated radio and TCP/IP networks.

You’ll specifically support the Network and Telecom design team in designing, deploying and validating network and telecom network & security solutions.

We’ll look to you for:

Understanding and interpreting network and cybersecurity requirements aligned with standards and regulations
Assisting the Lead System Designer and working as part of the Network team
Reviewing cybersecurity risk assessments and contributing to mitigation strategies
Performing Network Security Engineering tasks to meet program objectives
Documenting technical data in accordance with engineering policies and procedures
Supporting the set-up and management of firewalls, VPN, and IPsec configurations
Participating in installation, testing, commissioning, and maintenance activities

All About You

We value passion and attitude over experience. That’s why we don’t expect you to have every single skill. Instead, we’ve listed some that we think will help you succeed and grow in this role:

Currently enrolled in a Bachelor's degree in Engineering, Networking, Telecommunications, or Cybersecurity
Preferred related academic courses in networking and cybersecurity
Hands-on basic experience with firewalls and Active Directory for networks
Familiarity with network security and access policies, cybersecurity principles, technologies, and solutions
Understanding of IPsec, ciphers, GPO, central authentications, antivirus solutions, and IDS
Basic knowledge of monitoring tools and cybersecurity platforms
Knowledge of virtualization concepts
Superior attention to detail and accuracy

You don’t need to be a train enthusiast to thrive with us. We guarantee that when you step onto one of our trains with your friends or family, you’ll be proud. If you’re up for the challenge, we’d love to hear from you!
