Core Values : A culture that prioritizes safety, technical excellence, and the delivery of practical, field-proven solutions.

Responsibilities

We are looking for a Senior Refrigeration Engineer / Designer who can design robust refrigeration systems that meet customers’ cooling needs. You will work with sales, engineering, and production teams to :

• Evaluate customers’ process to determine their cooling requirements (load profiles, safety and operability constraints).
• Design complete refrigeration systems and controls strategies that meet customer requirements in the real life. - - Support commissioning and troubleshooting in the field to ensure systems perform as designed and root cause any issues.

Additional Responsibilities :

1. Applications and Sales Support

Customer Analysis : Evaluate and understand customer process requirements, operating profiles (continuous vs. batch, pull-down vs. steady load), and specific constraints.

Technical Validation : Verify Sales’ proposals by performing cooling load, energy balance, and equipment sizing calculations.

Bidding Support : Support the sales team during the bidding phase by providing technical insight and performance estimates.

System Design : Design skidded or built-up refrigeration systems and process chillers using HFC / HFO and ammonia.

Operational Strategy : Define system operating envelopes, setpoints, and capacity-control strategies (VFDs, slide valves, cylinder unloading, etc.).

Process Mapping : Develop and review process flows and P&IDs for new systems and major retrofits.

2. Controls and Equipment Operation

Controls Narratives : Develop clear controls narratives that link process requirements to system behavior and setpoints.

Programming Collaboration : Work with PLC programmers to define sequences of operation, alarm strategies, and interlocks that protect equipment and product.

Safety Logic : Provide input to PLC / HMI logic to ensure the system operates safely and efficiently while protecting against potential misuse.

Commissioning Support : Support commissioning teams by validating design intent, tuning control loops, and resolving startup issues to ensure the system meets customer requirements.

3. Project Execution & Documentation

Technical Documentation : Produce and / or review design reports, datasheets, equipment schedules, and O&M manuals.

Design Oversight : Work with CAD / design teams to review GA layouts and skid designs for serviceability, piping practices, and constructability.

Risk Management : Participate in design reviews, HAZOPs, risk assessments, and value-engineering sessions.

Cross-Functional Support : Provide technical support to project managers, manufacturing, and procurement when design changes or substitutions are required.

4. Customer Support & Life-Cycle Involvement

Root-Cause Analysis : Support the service team with troubleshooting chronic system issues, such as capacity shortfalls, nuisance trips, oil management, or poor pull-down.

System Upgrades : Recommend and scope upgrade projects, including retrofits, controls upgrades, capacity expansions, and efficiency improvements.

Technical Training : Provide occasional training to customer operators and internal teams on refrigeration system operations and best practices.

5. Safety, Codes & Compliance

Regulatory Compliance : Ensure all designs comply with relevant codes and standards, including CSA B52, ASHRAE 15, applicable building and mechanical codes, and provincial regulatory requirements.

Safety Integration : Incorporate safety devices, relief systems, and safe operating procedures into every system design.

Standardization : Contribute to the development of internal engineering standards and design guidelines.

Qualifications

Must-Have Qualifications :

Professional Experience : 8+ years of experience in industrial or commercial refrigeration system design, applications engineering, or installation / commissioning technical support.

System Design Expertise : Demonstrated experience designing complete refrigeration systems and involvement in system integration with customer processes.

Technical Knowledge : Strong understanding of refrigeration cycles, compressor performance, superheat control, oil management, and refrigeration controls.

Drafting & Design Proficiency : Proven ability to read and produce P&IDs, control narratives, and general arrangement (GA) drawings.

Codes & Compliance : Familiarity with Canadian codes and standards related to refrigeration, including CSA B52, ASHRAE 15, provincial regulations, and ASME B31.3 / B31.5.

Communication Skills : Strong ability to explain complex technical concepts to diverse stakeholders, including Sales, Production, Service, Field Technicians, and Management.

Nice-to-Have / Assets :

Professional Designation : Licensed P.Eng. in Ontario.

Practical Experience : Journeyperson Refrigeration Mechanic (e.g., 313A) or significant hands-on commissioning and service experience.

Controls Knowledge : Experience with PLC / HMI platforms (e.g., Rockwell / Allen-Bradley, Siemens, Schneider) and BMS integration.

Natural Refrigerants : Experience with industrial refrigeration using natural refrigerants (NH₃, CO₂) in addition to Freon systems.

Industry Software : Familiarity with selection tools and software from major compressor and component manufacturers.
