As a Staff Software Engineer on the HelioScope team, you’ll operate as a technical leader with broad influence across the product and engineering organization. You’ll work across the stack to design, build, and evolve systems that support complex workflows, large datasets, and performance-critical use cases.
Job Responsibility:
Set technical direction for major areas of the HelioScope codebase, balancing performance, scalability, and developer experience
Design and implement complex systems and features across the stack, including greenfield initiatives and foundational improvements
Lead large initiatives from early technical exploration through delivery, aligning stakeholders and driving execution
Influence architecture and engineering standards through design reviews, technical proposals, and hands-on contributions
Partner closely with Product, Design, QA, and customer-facing teams to translate real-world needs into durable technical solutions
Raise the bar for engineering quality through mentorship, code reviews, and modeling strong technical judgment
Identify and proactively address technical risk, legacy constraints, and opportunities for long-term simplification
Requirements:
8+ years of experience building and maintaining high-quality software systems, with demonstrated ownership of complex technical problems
Working understanding of photovoltaic system design concepts, including core components, basic wiring principles, shade analysis, and annual energy production modeling
Strong proficiency in at least one core programming language, ideally Python, JavaScript, TypeScript, or React
Deep understanding of software design principles, patterns, and tradeoffs at both component and system levels
Experience designing and evolving APIs, data models, and cloud-native architectures in production environments
Proven ability to operate in ambiguity—breaking down loosely defined problems and driving them to practical solutions
A track record of technical leadership through influence, not authority, across teams and disciplines
Comfort communicating complex technical ideas clearly in written and spoken English
Nice to have:
Experience working on performance-sensitive or computation-heavy systems
Background in applied mathematics, 2D/3D modeling, or electrical or energy systems
Familiarity with technologies such as Redux, Flask, Celery, Redis, Postgres, C++, WebGL, Three.js, or CUDA
Passion for improving developer productivity through tooling, CI/CD, observability, and workflow automation
