How to Apply for Full Stack Software Engineer

at Allye Energy

🏢 About Allye Energy

Allye Energy is revolutionizing energy storage to accelerate grid decarbonization while cutting energy costs by up to 50%. They're tackling one of the most critical challenges in renewable energy integration - making battery storage systems smarter and more economically viable. Working here means directly contributing to the clean energy transition with technology that has immediate real-world impact.

About This Role

This Full Stack Software Engineer role focuses on building the core platform for Allye's energy management system, from real-time battery control to predictive analytics. You'll be developing the software that enables intelligent battery scheduling, performance optimization, and revenue maximization for energy storage systems. Your work directly impacts how efficiently renewable energy can be stored and deployed on the grid.

💡 A Day in the Life

A typical day involves developing Python microservices for battery data processing, implementing AWS Lambda functions for real-time telemetry handling, and optimizing database queries for performance analytics. You might work on integrating new battery systems using Modbus protocols, then switch to building dashboard features for customer monitoring interfaces, all while collaborating on algorithms for energy price optimization.
