About Verdyn

Verdyn is a Canadian power infrastructure solutions company that designs, manufactures, and delivers advanced electrical systems for demanding environments where grid capacity, power quality, and system response are mission-critical.

Built around advanced power electronics, control software, and modelling-first engineering, Verdyn delivers turnkey solutions from grid connection to load — combining Canadian manufacturing and testing, system integration, commissioning, and long-term support. Our work spans utility, industrial, data centre, energy storage, and EV charging applications. At Verdyn, we don't just offer jobs — we build careers.

About the Role

As an integral part of Verdyn's dynamic engineering team, we invite you to apply your creativity and technical expertise to the mechanical design of our power infrastructure products — from power-electronics enclosures and cabinets to the thermal and structural systems that keep high-power-density equipment running reliably in the field.

In this role you will own mechanical design from concept through prototype, testing, and production, working shoulder-to-shoulder with our electrical, power-electronics, and firmware engineers. If you enjoy turning complex electrical systems into robust, manufacturable, thermally sound hardware, this is a high-ownership role with real impact on products that solve mission-critical power challenges.

Role Overview

We're looking for an engineer who can model, simulate, and physically build the thermal systems that keep high-power-density electronics alive — cold plates, heater plates, heat sinks, and air- and liquid-cooling loops integrated directly into PCBs, power modules, electrical cabinets, and enclosures. This is a thermal-engineering-first role with strong mechanical design responsibilities: you'll set the thermal architecture, prove it out in simulation and on the bench, and carry it through to a manufacturable enclosure.

Key Responsibilities

Thermal Design & Analysis (core focus)

- Own the thermal architecture of power-electronics products — from device junction through board, module, enclosure, and ambient — for STATCOM, E-STATCOM, energy storage, DC power delivery, and EV charging systems.
- Design and develop cooling systems: liquid cold plates, heat sinks, heat pipes and vapor chambers, forced- and natural-convection air paths, plenums, ducting, and fan/blower/pump selection sized to real duty cycles.
- Design heating plates and temperature-control systems — resistive heater plates, thermoelectric (Peltier) stages, and enclosure heaters — for cold-start, condensation and humidity control, and temperature conditioning of cabinets and electronics.
- Build thermal-resistance networks (junction-to-case, case-to-sink, sink-to-ambient) and define thermal budgets, margins, and component derating to meet reliability and lifetime targets.
- Run CFD and thermal simulations (Ansys Icepak/Fluent, Flotherm, 6SigmaET, or SolidWorks Flow Simulation) at component, board, and full-enclosure level,



under nominal and worst-case operating and environmental conditions, and translate results into concrete design changes.
- Drive board-level thermal design with the PCB and power-electronics teams: component placement, copper pour and plane strategy, thermal vias, layer stack-up for heat spreading, and localized cooling for hot devices.
- Select and characterize thermal interface materials (greases, gap pads, phase-change materials, potting/encapsulants) and specify mounting pressure, flatness, and interface requirements.
- Define and execute thermal validation testing — thermocouple and RTD instrumentation, IR thermography, flow and pressure-drop measurement, and thermal-cycling — and correlate test data back to models to close the simulation-to-reality loop.

Mechanical Design & Integration
- Design and develop mechanical enclosures, cabinets, and housings that host the thermal solution and the electrical assemblies for power-electronics systems.
- Produce detailed 3D CAD models, assemblies, and manufacturing drawings with appropriate GD&T; (SolidWorks or equivalent).
- Own the mechanical and thermal integration of busbars, power modules, magnetics, cold plates, coolant routing, and electrical assemblies in close collaboration with the electrical and power-electronics teams.
- Validate structural, vibration, shock, and seismic performance through hand calculations and finite element analysis (FEA), including the mechanical robustness of cooling hardware and coolant connections.
- Refine designs for manufacturability and assembly (DFM/DFA), working with sheet-metal, machining, fabrication, and cold-plate/extrusion suppliers to optimize cost, quality, and lead time.

Prototyping, Build & Documentation
- Lead prototyping, build support, and design-validation testing; drive thermal and mechanical issues to root cause and close them out with sound engineering changes.
- Support manufacturing and factory testing by preparing bills of materials, assembly instructions, coolant-fill and leak-check procedures, and transparent technical documentation.
- Ensure compliance with relevant enclosure and environmental standards (e.g., IP/NEMA ratings, UL/CSA enclosure requirements, and seismic considerations), including thermal and airflow implications of sealing and ingress protection.
- Communicate effectively with system architects, project managers, and external stakeholders to keep designs on schedule and aligned to requirements.

Qualifications

Required

- Bachelor's degree in Mechanical Engineering, Thermal/Thermofluids Engineering, or a closely related field.
- 3+ years of experience in mechanical and thermal design, ideally for electromechanical, electronics-enclosure,



or power/electrical hardware products.
- Demonstrated experience designing cooling and/or heating systems for electronics or power systems — cold plates, heat sinks, liquid loops, or heater/temperature-control assemblies — from concept through validation.
- Hands-on thermal simulation experience (CFD and/or thermal-resistance modeling) with the ability to build a model, trust or challenge the results, and turn them into design decisions.
- Solid grasp of heat-transfer fundamentals — conduction, convection, radiation, and fluid flow — applied to real hardware.
- Proficiency with 3D CAD (SolidWorks preferred) and strong command of GD&T; and detailed drawing practices.
- Working knowledge of FEA / structural simulation and the ability to translate results into design changes.
- Familiarity with sheet-metal design, machining, and fabrication processes, and with DFM/DFA principles.
- Strong self-management, attention to detail, and the ability to work independently to project timelines.

Preferred

- Professional Engineer (P.Eng.) licence in Ontario, or EIT working toward licensure.
- Depth in one or more thermal/CFD tools (Ansys Icepak/Fluent, Flotherm, 6SigmaET, or SolidWorks Flow Simulation) and experience correlating models against bench data.
- Experience with PCB-level thermal design — thermal vias, copper spreading, component derating — and with power-module cooling (IGBT/SiC/MOSFET packages).
- Experience specifying and characterizing thermal interface materials, and designing liquid-cooling hardware (cold plates, manifolds, fittings, leak testing).
- Background in power electronics, industrial electrical equipment, or energy hardware.
- Familiarity with enclosure and safety standards (NEMA, IEC/IP, UL 508A, CSA) and seismic/structural requirements.
- Experience with thermal test and instrumentation (thermocouples, IR thermography, flow/pressure measurement, thermal cycling).
- Experience with PLM/PDM systems, version control, and structured engineering-change processes.
- Comfort in a fast-paced, growing company where you can help shape processes and products from the ground up.

What We Offer
- A high-impact, high-ownership engineering role at a fast-growing Canadian power-infrastructure company.
- The opportunity to design thermal and mechanical hardware for mission-critical systems across utility, industrial, data centre, storage, and EV charging markets.
- A collaborative, multidisciplinary team and hands-on involvement from concept through manufacturing and commissioning.
- A competitive compensation and benefits package.
