How to Apply for Engineer II

at Kaluza

🏢 About Kaluza

Kaluza stands out as a technology company specifically focused on the energy sector, building intelligent software that helps energy suppliers accelerate decarbonization. Their mission-driven approach combines technical innovation with real-world environmental impact, making it appealing for engineers who want their work to contribute to sustainability goals. The company operates within the OVO Group ecosystem, providing stability while working on cutting-edge problems in a critical industry.

About This Role

As an Engineer II at Kaluza, you'll be building and maintaining backend services using TypeScript that directly support energy suppliers in managing their operations more efficiently and sustainably. This role is impactful because you'll contribute to event-driven systems that process energy data in near real-time, enabling smarter decisions that drive decarbonization. You'll collaborate closely with product managers and designers to deliver user-focused features that make a tangible difference in the energy transition.

💡 A Day in the Life

A typical day might start with a stand-up discussing progress on backend services for energy data processing, followed by implementing new features in TypeScript for an event-driven system. You'd likely collaborate with product managers to understand user needs, write tests for your code, and participate in code reviews to maintain high engineering standards. The work involves balancing immediate feature development with maintaining and improving existing services that process critical energy data.
