How to Apply for Senior Software Engineer, Computation
at Aurora Solar
🏢 About Aurora Solar
Aurora Solar is a mission-driven company at the forefront of the solar energy revolution, leveraging AI and data to make solar adoption simple and predictable. As a Certified Green Business and one of BuiltIn's Best Remote Companies for 2025, they combine technical excellence with a strong commitment to sustainability. Working here means contributing directly to the global transition to clean energy while solving complex computational challenges.
About This Role
As a Senior Software Engineer on the System Design Pod, you will build the core computation engines that power accurate solar design, including load modeling, battery electrical design, and performance simulation. Your work will directly impact millions of solar projects, ensuring high-fidelity designs that enable solar professionals to sell and install systems at scale. This role sits at the intersection of software engineering and applied math, making it ideal for someone who enjoys deep technical challenges with real-world environmental impact.
💡 A Day in the Life
A typical day might start with a stand-up meeting with the System Design Pod to discuss progress on simulation engine improvements. You'll spend time coding in C++ or Rust, optimizing algorithms for battery sizing or load modeling, and reviewing pull requests from teammates. Afternoons often involve collaborating with product managers to refine requirements for new features, followed by deep-focus work on performance profiling or writing unit tests for a new computational model.
🚀 Application Tools
🎯 Who Aurora Solar Is Looking For
- Strong background in computational geometry, numerical methods, or physics-based simulation, with experience building algorithms for real-world engineering problems.
- Proficiency in a systems language like C++, Rust, or Go, and familiarity with performance optimization and distributed computing.
- Ability to collaborate cross-functionally with product managers, designers, and domain experts to translate requirements into robust, scalable software.
- Passion for renewable energy and a desire to apply technical skills to accelerate the adoption of solar technology.
📝 Tips for Applying to Aurora Solar
Highlight specific projects where you built or optimized computational models (e.g., simulation engines, CAD tools, or physics-based systems) and quantify the impact (e.g., speed improvements, accuracy gains).
Tailor your resume to emphasize experience with algorithms and data structures relevant to geometry processing, optimization, or simulation, rather than generic web development.
In your cover letter, connect your personal motivation for working in clean energy to Aurora's mission, and mention any familiarity with solar design or energy modeling.
Research Aurora's product features (e.g., PV design, battery storage, load calculations) and mention how your skills could enhance specific capabilities.
Since the role is remote, demonstrate your ability to work asynchronously and communicate effectively across time zones, possibly with examples from past remote work.
✉️ What to Emphasize in Your Cover Letter
["Express genuine passion for solar energy and Aurora's mission to make solar adoption simple and predictable.", "Emphasize your experience with computational geometry, numerical simulation, or similar technical domains that align with the System Design Pod's work.", 'Showcase your ability to work on complex, math-intensive problems and translate them into production-quality software.', 'Mention your collaborative approach and experience working with cross-functional teams to deliver impactful technical solutions.']
Generate Cover Letter →🔍 Research Before Applying
To stand out, make sure you've researched:
- → Explore Aurora's product features, especially the System Design capabilities: PV design, battery storage, load calculations, and performance simulation.
- → Read about the company's engineering culture and remote work practices on their blog or BuiltIn profile.
- → Understand the solar industry basics: net metering, time-of-use rates, and how software can optimize system sizing.
- → Look into the technical challenges of solar design, such as shading analysis, roof geometry, and electrical code compliance.
💬 Prepare for These Interview Topics
Based on this role, you may be asked about:
⚠️ Common Mistakes to Avoid
- Submitting a generic application without mentioning solar or computational geometry – this role is highly specialized.
- Overemphasizing front-end or mobile development experience, which is not relevant to this back-end/computation role.
- Failing to demonstrate quantitative impact (e.g., 'optimized algorithm by 50%') – Aurora values data-driven results.
- Neglecting to show enthusiasm for the mission – the company culture is deeply rooted in sustainability.
