Our award‑winning software puts the power of data and technology into the hands of every solar professional to make solar adoption simple and predictable. Our software has designed millions of solar projects so far, empowering solar companies to sell, design, and install residential and commercial solar arrays accurately, seamlessly, and at scale. We’ve been named one of "The Best Remote Companies" by BuiltIn.We’re in this together to support the world’s transition to solar.

The System Design

Pod sits at the heart of Aurora's core platform, building the computation engines that make accurate, high-fidelity solar design possible. Our team owns the algorithms and systems that power load and utility bill modeling, whole home electrification, PV and battery electrical design, and system performance simulation. The work is deeply technical, operating at the intersection of software engineering and applied math, and it has an outsized impact on the quality of every solar project designed in Aurora.

We work closely with product managers, designers, research engineers, and QA to turn hard physics and engineering problems into software that installers can trust. If you like digging into a tough problem, debating the right approach, and shipping something that holds up in the real world, you'll fit in here. As a Senior Software Engineer on the System Design Pod, you'll help build the next generation of PV and storage design tools at Aurora.

You'll lead technical features from discovery through general release, propose new mathematical approaches to long-standing problems, and push our simulation and optimization work forward alongside a team that cares deeply about getting it right. This role sits at the intersection of software engineering and applied math, with a direct line to the quality of every project designed on the platform. The technical and business contexts are steep at first, and the payoff is real:



you'll move the accuracy and capability of solar design forward for thousands of installers and millions of homeowners.
