Full job description

ROLE OVERVIEW

Streamline Control is seeking an Ignition SCADA Specialist with strong Ignition platform expertise to design, implement, and support modern SCADA solutions for clients across oil and gas, utilities, and manufacturing. You will be part of a growing Modern SCADA practice — building Ignition-based HMI and dashboard applications, configuring MQTT and edge ecosystems, and contributing to greenfield and migration projects from legacy SCADA platforms.

This role suits a hands-on SCADA professional who has moved beyond entry-level work and is ready to own significant pieces of project delivery under the direction of senior team members. You will work directly with clients, contribute to design decisions, and develop toward Senior Specialist responsibilities through a structured technical pathway.

KEY RESPONSIBILITIES

Ignition SCADA Development

Configure, develop, and test Ignition SCADA systems (Perspective and Vision) for client projects across greenfield builds, expansions, and platform migrations.
Develop and maintain HMI screens, dashboards, alarm displays, and operator interfaces following modern HMI design principles and client style guides.
Build and maintain Ignition tag structures, UDTs (User Defined Types), alarm configurations, and historical data pipelines.
Develop scripting in Python/Jython within Ignition for gateway events, tag change scripts, and expression logic.

MQTT and Edge Computing

Configure and deploy MQTT-based architectures using Ignition modules (Cirrus Link MQTT Engine, Transmission, Distributor) and Sparkplug B payload specification.
Implement edge-of-network solutions using Ignition Edge for remote and field deployments, ensuring reliable store-and-forward data delivery.
Integrate Ignition with broker infrastructure (e.g., HiveMQ, Chariot) and downstream consumers including historians, analytics platforms, and IIoT ecosystems.

Industrial Protocols and PLC Integration

Configure Ignition OPC UA server and device connections to PLCs and RTUs across major vendors (Allen-Bradley, Siemens, Schneider, ControlLogix, Modicon).
Work with industrial protocols including Modbus TCP/RTU, OPC UA, EtherNet/IP, and DNP3 in field and substation environments.
Coordinate with controls engineers and field technicians on tag mapping, address verification, and PLC-to-SCADA data flow validation.

Client Project Delivery

Contribute to project deliverables including functional design specifications, configuration documentation, FAT/SAT procedures, and as-built records.
Participate in client design workshops, requirements gathering, and technical reviews; translate operational needs into Ignition configurations.
Support project coordination activities — scope tracking, status reporting, and change management — under the guidance of the Practice Lead or assigned Project Manager.
Participate in commissioning, site acceptance testing, and go-live support, including travel to client facilities.

Systems, Infrastructure and Cybersecurity

Deploy and maintain Ignition Gateway instances on Windows and Linux servers, including SQL Server and PostgreSQL database integration.
Work within virtualised environments (Hyper-V, VMware ESXi) for Ignition Gateway deployments and disaster recovery configurations.
Apply OT cybersecurity practices including network segmentation, certificate management for MQTT/TLS, and hardening of Ignition Gateways in accordance with IEC 62443 and client standards.

Collaboration and Mentorship

Collaborate with Senior SCADA Specialists, OT Specialists, and Leak Detection Advisors on cross-functional engagements.
Provide informal mentorship and code review for entry-level SCADA team members.
Contribute to internal knowledge base, reusable Ignition templates, and practice standards.

ESSENTIAL REQUIREMENTS

Bachelor's degree or diploma in Computer Science, Computer Engineering, Electrical Engineering, Instrumentation, or a related technical discipline.
4–10 years of hands-on experience with SCADA, IIoT, or industrial control systems.
Demonstrated experience developing HMI and operator interfaces on a modern SCADA platform — Ignition (Perspective or Vision) strongly preferred.
Working knowledge of MQTT and Sparkplug B in industrial contexts.
Working knowledge of industrial protocols (Modbus, OPC UA, EtherNet/IP, DNP3).
Proficiency in at least one scripting or programming language (Python/Jython, C#, or Java); ability to write production scripts within Ignition.
Experience with relational databases (SQL Server, PostgreSQL, or MySQL) — schema design, queries, and Ignition database integration.
Strong written and verbal communication skills; able to document configurations and present technical material to clients.
Willingness to travel to client facilities across western Canada and, on occasion, further afield.

PREFERRED QUALIFICATIONS

Inductive University training completion and/or Ignition Core or Gold Certification.
Experience with Cirrus Link modules (MQTT Engine, Transmission, Distributor) and Sparkplug B implementation.
Exposure to AVEVA Enterprise SCADA (OASyS) — particularly useful for clients running mixed or migrating environments.
Hands-on PLC configuration experience (Allen-Bradley/Rockwell Studio 5000, Siemens TIA Portal, Schneider Unity/EcoStruxure).
Experience with Ignition Edge or other edge-of-network deployments in remote/field environments.
Familiarity with IT infrastructure components — Active Directory, Hyper-V or VMware, Windows/Linux server administration.
Project coordination experience or formal training (PMP fundamentals, CAPM, or equivalent practical experience leading project workstreams).
Exposure to OT cybersecurity frameworks (IEC 62443, NIST 800-82).
Experience to Snowflake, Canary, AVEVA PI System, or Flow Software historians/analytics platforms.

CORE COMPETENCIES

Creative technical thinker — approaches SCADA design problems with curiosity and a genuine interest in modern, open architectures.
Hands-on builder — productive in Ignition Designer and equally comfortable in a server console, a control room, or a client workshop.
Clear communicator — produces documentation and presents technical material with accuracy and professionalism.
Client-aware — understands that SCADA touches operations directly and exercises appropriate caution in production environments.
Collaborative — works well alongside controls, OT, IT, and operations stakeholders on shared deliverables.
Self-directed — capable of owning configuration work, raising blockers early, and delivering against project milestones.

WORKING CONDITIONS

Hybrid working from the Calgary office with travel to client control rooms, plants, and field sites across western Canada.
Work at active industrial facilities requiring adherence to client safety management systems, PPE requirements, and permit-to-work procedures.
Occasional on-call availability and after-hours work during commissioning, cutovers, and go-live windows.
Flexibility during testing campaigns, FAT/SAT events, and project delivery milestones.

AT A GLANCE

Required: 4–10 Yrs SCADA / ICS Experience │ Ignition (Perspective / Vision) │ HMI & UI Development │ MQTT / Sparkplug B │ Industrial Protocols (Modbus, OPC UA) │ Scripting (Python / Jython) │ SQL
