Job Description Senior Software Developer Simulation and Desktop Applications

Location: Kelowna, BC (preferred) or remote within North America

Type: Full-time, permanent

Reports to and works with: Software architecture lead

About the role

Boyd Thermal by Eaton builds commercial thermal and fluid simulation software (CFD) used by engineers at major electronics, power, and industrial companies to design cooling systems. The product is mature Windows desktop software with a long history, an active solver development program, and a small team of very experienced developers, which means the work is unusually broad: GUI, solver physics, geometry and meshing, native extension modules, build and release engineering, and internal tooling, often in the same month. We are looking for one experienced generalist developer to work alongside our software architect. Not a specialist in one framework, and not someone who needs a defined ticket queue: someone who can be handed a hard, loosely specified problem,



work out what the right solution actually is, and build it.

What you will work on first

Your first project is a standalone desktop application for our network flow solver, built on prototype work that already exists. It is a node and edge network editor for fluid flow and thermal networks, driving a native C++ solver core, with results visualization and reporting. The current direction is C# on Windows, so you would own the application layer, the interop boundary to the native solver, the UX, and the packaging and installer. It is a good first project deliberately: real scope, real users, explicit boundaries, and it teaches you the physics and the domain vocabulary before you are dropped into the larger legacy codebase.

What you will work on after that

- Solver and numerics work in Python and C++ (finite volume CFD, conjugate heat
