## Description

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.

Your Impact

 * Design, build, and maintain the backend systems and computation engines behind Aurora's solar and electrical design workflows
 * Advance our simulation and optimization work across PV and battery storage system layout, component selection, and electrical configuration
 * Partner with product managers, designers, research engineers, and fellow engineers to turn complex physical models and engineering constraints into reliable, scalable software
 * Shape the architecture of our simulation and computation infrastructure so it stays correct, fast, and maintainable as it grows
 * Write clean, well tested code and raise the engineering bar through the patterns you establish
 * Mentor teammates and show up fully in technical discussions, code reviews, and design documents
 * Own the services you build end to end, including on-call rotation
