Senior OT Network Engineer

PowerON Energy Solutions

Full-time

Hybrid | Toronto, ON, Canada

This posting is for a newly created position

Salary range $130,000 - 145,000

Reporting to the Head of Energy Markets & Software Solutions, you will be part of a team developing advanced OT and energy solutions for large business and institutional customers, including electric vehicle charging, battery energy storage systems (BESS), solar PV, microgrids, and distributed energy resources. Your work will directly support the design, deployment, cybersecurity, operation, and lifecycle management of mission-critical operational technology infrastructure that enables the transition to a clean energy economy.

The ideal candidate combines strong OT networking and cybersecurity expertise with practical field experience supporting industrial control systems, SCADA environments, and cloud-connected energy infrastructure. This individual will support projects across the full lifecycle — from architecture and requirements development through commissioning, operations, and ongoing support — while helping establish scalable, secure-by-design OT network standards across PowerON’s growing fleet electrification portfolio.

RESPONSIBILITIES

Project Design, Architecture & Systems Integration

• Design and develop secure, scalable, and highly available OT network architectures for electrification infrastructure projects including EV charging depots, BESS, DERs, and microgrids.

• Support development of end-to-end OT infrastructure designs including industrial networking, firewall segmentation, remote access architectures, SCADA communications, server infrastructure, virtualization, and cloud-connected OT solutions.

• Develop network architectures supporting secure integration between OT systems, cloud platforms, enterprise IT systems, and third-party vendor environments.

• Support implementation of resilient industrial network topologies including PRP, HSR, redundant ring architectures, and industrial failover strategies.

• Collaborate with systems integrators, software vendors, consultants, utilities, and engineers of record to ensure alignment between OT network architecture and overall project objectives.

• Support evaluation and selection of OT infrastructure technologies including firewalls, switches, cellular gateways, servers, VPN/remote access technologies, and industrial communications equipment.

Cybersecurity & Governance

• Review vendor and contractor design deliverables to ensure compliance with PowerON and client cybersecurity, networking, and operational requirements.

• Support secure-by-design implementation principles aligned with ISA/IEC 62443, NIST SP 800-82, and Zero Trust principles.

• Develop and maintain firewall policies, access control rules, network segmentation strategies, and data flow matrices.

• Support secure remote access solutions for employees, contractors, and vendors, including administration of VPN and privileged access management (PAM) solutions.

• Participate in cybersecurity risk assessments, technical reviews, and mitigation planning.

Project Delivery & Technical Oversight

• Support projects across the full lifecycle including requirements development, detailed design review, procurement support, FAT/SAT testing, commissioning, and operational turnover.

• Develop network and infrastructure requirements documentation issued to vendors, contractors, and engineering consultants.

• Ensure final deliverables align with approved requirements, standards, and operational expectations.

• Coordinate with multidisciplinary teams including SCADA, electrical, cybersecurity, and operations stakeholders.

• Support troubleshooting and technical resolution of OT network and communications issues during construction, commissioning, and operations.

Operations & Lifecycle Support

• Provide operational support for deployed OT infrastructure across active electrification sites.

• Support maintenance and lifecycle management of industrial firewalls, managed switches, OT servers, virtualization infrastructure, remote access platforms, and industrial communications devices.

• Maintain operational OT network documentation including IP address schemas, network topology diagrams, AD roles and permissions, firewall rule matrices, VLAN segmentation documentation, and remote access inventories.

• Support system uptime, reliability, and operational continuity through proactive monitoring, troubleshooting, and coordination with operations teams, contractors and vendors.

• Participate in on-site activities as required to support commissioning, troubleshooting, incident response, and operational support.

QUALIFICATIONS

• University degree in Engineering, Computer Engineering, Electrical Engineering, Computer Science, or related technical field.

• 5+ years of experience supporting OT networks, industrial infrastructure, SCADA systems, or critical infrastructure environments.

• Strong understanding of VLANs, routing and switching, NAT, VPN technologies, firewall policy management, network segmentation, and redundant network architectures.

• Experience configuring and supporting industrial networking and security technologies such as Fortinet, Palo Alto, Cisco Industrial Ethernet, RuggedCom, Windows Server, and virtualization environments.

• Familiarity with industrial protocols including Modbus TCP/IP, DNP3, IEC 61850, OPC UA, MQTT, and SCADA/EMS systems.

• Experience supporting cloud-connected OT architectures and hybrid IT/OT environments.

• Familiarity with ISA/IEC 62443 and NIST SP 800-82.

• Experience reviewing technical documentation, network drawings, and vendor deliverables.

• Strong troubleshooting and problem-solving skills.

• Strong written and verbal communication skills.

While all qualified candidates are invited to apply, we particularly welcome applications from women, persons with disabilities, First Nations, Métis and Inuit peoples, members of visible minorities, and 2SLGBTQ+ persons.
