Streamline Control Solutions, part of SGS — the world’s leading testing, inspection, and certification company operating across 115 countries — is a leading operational technology solutions provider specializing in industrial automation, SCADA, data historians, and analytics for the energy sector. We work with major oil and gas producers across North America, helping them modernize critical infrastructure and unlock value from their operational data.
Streamline Control is looking for a proven OT Specialist to take ownership of industrial infrastructure and cybersecurity across our oil and gas operations. You will lead the design, implementation, and ongoing management of OT networks, remote communications, virtualisation platforms, and security tooling — ensuring high availability and compliance across all operational sites.
This role carries technical leadership responsibilities. You will mentor junior team members, drive standards, and act as a subject matter expert during projects, audits, and incident response.
OT Network Architecture
- Design and maintain OT network architectures in accordance with the Purdue Model, including DMZ configuration and inter-level segmentation.
- Implement and manage high-availability topologies — ring protocols (MRP, PRP, HSR), failover mechanisms, and redundant paths for critical process networks.
- Lead network assessments, capacity planning, and performance optimisation across plant and field networks.
Remote Communications
- Own the deployment and lifecycle management of VSAT, radio, and cellular (4G/5G) communication systems at remote and offshore sites.
- Optimise link performance, QoS, and bandwidth allocation to ensure reliable SCADA and safety-critical traffic delivery.
- Manage vendor relationships and service agreements for satellite and telecommunications providers.
Virtualisation and Systems
- Manage Hyper-V and ESXi environments including cluster operations, VM lifecycle, storage integration, and disaster recovery.
- Lead computer system design activities — hardware specification, architecture documentation, FAT/SAT, and commissioning.
- Drive patching strategies and firmware lifecycle management within change control frameworks.
Cybersecurity
- Implement and enforce OT cybersecurity standards (IEC 62443, NIST 800-82) across all infrastructure.
- Deploy and administer security tooling — preferably Claroty (CTD, xDome) and Cyolo for zero-trust remote access.
- Coordinate security audits, vulnerability assessments, and incident response for OT environments.
Leadership and Mentoring
- Mentor and develop junior OT specialists, providing technical guidance and knowledge transfer.
- Author and maintain technical standards, SOPs, and runbooks for OT infrastructure operations.
- Represent OT during cross-functional projects, capital planning, and management reviews.
