About You
You are a hybrid--part energy modeler, part programmer. Perhaps you got your start at a mechanical or architectural engineering firm, or maybe a software startup or national lab. Whatever path led you to energy modeling, you discovered that the software developers had the best tools and techniques to make your work easier. Even though you may not have heard it before, the mantra “model like a programmer” sounds like your perfect jam. Today you find yourself pushing the limits of your energy modeling tools on a daily basis, and it frustrates you to no end. You think there MUST be better ways to do software for building energy modeling. What if you could put your hybrid superpowers to good use and help elevate the next generation of energy modeling tools for everyone? What if you could enjoy the challenge of interesting, creative work, while also having a meaningful impact on the planet? What if you could play a major role in a small, but growing, dynamic team of mechanical engineers, scientists, and programmers? Sound like you?
