Job summary

Valar Atomics is building high-temperature gas-cooled small modular reactors and seeks an OT engineer to support integrated OT across reactor, fuel, and power-conversion programs. You will work on SCADA, OT networking, cybersecurity, data systems, and verification/ commissioning with progressively increasing ownership in field tasks.

You will deploy and test OT architectures, administer industrial environments, and contribute to rigorous procedures and documentation in a hands-on industrial

Qualifications

• Direct production experience with Rockwell FactoryTalk View SE, Linx, Historian SE/AVEVA PI, and AssetCentre, including distributed or redundant deployment, administration, backup/recovery, and troubleshooting.
• Strong capability in packet capture, protocol analysis, structured-cabling validation, network/data monitoring, and root-cause troubleshooting across Layer 1-7.
• Ability to build automation, services, test aids, and evidence-collection tooling using C#, PowerShell, CMD, or equivalent tools; strong technical writing, configuration-control, vendor-management, and field-troubleshooting skills.
• Frequent travel and hands-on field work in Orangeville are required. Formal degrees and certifications are not required; equivalent technical experience is acceptable.

Responsibilities

• Own assigned work packages and contribute to integrated OT architecture, standards, roadmaps, interfaces, lifecycle, security zones, addressing, naming/context, retention, configuration baselines, and technical health across Valar programs.
• Design, deploy, administer, test, and recover distributed or redundant FactoryTalk View SE, Linx, Historian SE/AVEVA PI, and AssetCentre environments, including HMI/alarm/tag standards, licensing, source control, audit, and change management.
• Administer supporting virtualization, Windows/SQL, Active Directory/PKI, service accounts, storage, backup, and disaster-recovery infrastructure with explicit ownership and controlled baselines.
• Design, configure, and troubleshoot Layer 1-7 OT networks using Arista, Palo Alto, or equivalent platforms; define routing, switching, segmentation, firewall policy, redundancy, time synchronization, monitoring, racks, structured cabling, copper, fiber, and optics.
• Design and validate air-gapped boundaries, unidirectional data flows, controlled remote access, and tightly controlled OT/enterprise/cloud interfaces that cannot interfere with control or credited safety functions.
• Deploy and operate historians, InfluxDB/SQL, virtualized data services, and RAID/ZFS or equivalent storage; build OPC UA/MQTT/API/ETL pipelines, semantic models, data contracts, and Grafana/query interfaces while preserving timestamps, quality, ordering, lineage, and access boundaries.
• Integrate PLCs, industrial protocols, FactoryTalk, historians, servers, endpoints, and operator/engineering systems while preserving clear ownership across IC&E, Infrastructure, SCADA, network, and data boundaries.
• Validate racks, patch panels, copper, fiber, optics, labeling, link performance, and physical-path diversity with infrastructure engineers and field contractors.
• Engineer and test retention, compression, query performance, collectives, buffering, replay, replication, high availability, backup/restore, and loss/duplicate detection; document failure behavior and recovery limits.
• Write and execute test procedures with prerequisites, hazards and controls, configuration, tools, step-by-step actions, expected results, evidence, rollback, and restoration.
• Implement monitoring, logging, configuration backup, capacity, data-quality, pipeline-health, and audit controls; automate deployment, validation, evidence collection, and recovery using C#, PowerShell, CMD, or equivalent tools.
• Troubleshoot the full stack using packet capture, protocol analysis, data-path tracing, logs, and queries; perform authorized OT cybersecurity testing and support hardening, patching, remediation, and incident response.
• Translate technical, regulatory, quality, and cybersecurity requirements into traceable verification plans and execute FAT, SAT, System Operational Verification Testing, cybersecurity, failure/recovery, failover, performance, and interface tests.
• Control test configurations and evidence; document discrepancies, support root-cause analysis, define retests, track corrective actions, and maintain diagrams, matrices, data models, build records, procedures, manuals, and runbooks.
• Lead or support design reviews, vendors, systems integrators, installation validation, integration, commissioning, failure testing, escalation, turnover, startup, outage, and incident activities.
