Senior Software Engineer, Computation

Aurora Solar develops software that helps solar professionals design and install residential and commercial solar systems. The Senior Software Engineer will build and maintain backend computation systems for solar and electrical design, advance simulation and optimization capabilities, and lead technical features from discovery through release. The role also involves shaping computation infrastructure, collaborating cross-functionally, mentoring teammates, and owning services end to end.

Responsibilities:

• 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

Requirements:

• 5+ years of professional software engineering experience with a strong backend foundation
• Academic background or equivalent skillset in computational mathematics, optimization, linear algebra, control theory, or numerical algorithms
• Hands-on experience with simulation or optimization
• Experience designing and building APIs, microservices, or data pipelines at scale
• Sharp algorithmic thinking, with the ability to reason about performance, correctness, and edge cases in computational systems
• Proficiency in one or more backend languages. Our stack is C++, Python, and Ruby, and relevant experience in other languages is welcome
• Strong written and verbal communication. You can explain complex technical ideas clearly and collaborate well on a distributed team
• Advanced degree (MS or PhD) in computer science, applied math, electrical engineering, physics, or a related field
• Familiarity with solar PV and battery technology, or electrical engineering concepts more broadly
• Experience with cloud-native compute infrastructure and batch or distributed processing systems
• A genuine pull toward renewable energy and the work of accelerating the transition
• Track record of thriving when the pace picks up and the problem space shifts
