- OT/ICS cybersecurity delivery
- Support cybersecurity assessments for Operational Technology (OT) environments (e.g., SCADA, PLC/DCS, wayside systems, tunnel systems, power/traction power, facilities/industrial controls, communications networks supporting operations).
- Contribute to OT security architecture and requirements baselining aligned to applicable standards (e.g., IEC 62443, ISO 27001, NIST guidance as applicable).
- Perform asset and data-flow discovery support, basic threat modeling, and segmentation / zoning-conduit analysis under senior guidance.
- Help develop security deliverables such as:
- Cybersecurity requirements registers / traceability matrices
- High-level security architecture diagrams (IT/OT boundaries, zones, remote access)
- Risk registers and treatment plans
- Security validation approaches (e.g., FAT/SAT cyber considerations, supplier assurance)
- Policies/procedures (remote access, patching, removable media, logging/monitoring)
- Consulting-style engagement support (plus)
- Participate in workshops and stakeholder interviews; capture decisions and translate them into clear, client-ready outputs.
- Contribute to presentations, memos, and reports with strong structure, visuals, and executive-ready wording.
- Support proposals/pursuits: scope drafting, assumptions, fee build-ups, and risk/mitigation inputs.
- Governance, assurance, and third-party/supplier assurance
- Support vendor/security documentation reviews (OT supplier security posture, system integrator materials, design packages).
- Help translate contractual, design, and governance obligations into actionable cyber requirements for delivery teams.
- Assist with assurance planning and evidence collection approaches for audits/independent reviews (as required by program governance).
- Collaboration & ways of working
- Work closely with cyber leads, systems engineering, OT SMEs, IT teams, and physical security counterparts to ensure unified security outcomes.
- Maintain strong documentation hygiene: version control, traceability, and clear decision logs.
- 2-5 years in cybersecurity, with demonstrated exposure to OT/ICS environments (rail/transit, utilities, manufacturing, energy, or similar critical infrastructure).
- Practical knowledge of OT concepts: SCADA/ICS components, Purdue model, segmentation, remote access, industrial protocols (high level), and operational constraints (availability, safety, maintainability).
- Experience producing structured cybersecurity deliverables (risk registers, requirements, assessments, architecture diagrams).
- Strong written and verbal communication; able to turn ambiguity into clear, professional outputs.
- Ability to operate in a multi-project consulting environment (prioritization, time management, stakeholder communication).
- Familiarity with rail/transit programs and system delivery lifecycle (requirements, design, implementation, testing/commissioning).
- Working knowledge of IEC 62443 (zones/conduits, foundational requirements), ISO 27001, NIST CSF/800-82, and/or relevant Canadian frameworks.
- Exposure to OT-relevant security practices (logging/monitoring patterns, secure remote access, vulnerability management constraints).
- Relevant certifications (one or more): GICSP, GRID, CISSP/SSCP, Security+, ISA/IEC 62443 training, Azure/AWS security fundamentals.
- Ramp up on major programs and produce high-quality deliverables with minimal rework.
- Build repeatable templates (requirements register, risk register, workshop notes, architecture visuals) to accelerate delivery.
- Demonstrate sound OT judgement: pragmatic, operations-aware recommendations (not IT-only thinking).
- Support at least one security workshop end-to-end (planning, facilitation support, outputs).
