How to Apply for Software Engineer II

at EnergyHub

🏢 About EnergyHub

EnergyHub is a mission-driven company at the forefront of the clean energy transition, specializing in distributed energy resource management. Unlike typical tech companies, they directly contribute to sustainability by optimizing electric vehicle charging and grid integration. Working here means your code directly supports reducing carbon emissions and building a more resilient energy system.

About This Role

This Software Engineer II role focuses on building the backend infrastructure for EnergyHub's EV platform, handling massive-scale data from millions of vehicles while developing both internal services and customer-facing APIs. You'll be working across the full stack - from data lakes and vehicle communication systems to front-end applications - ensuring seamless integration of all platform components. This position is impactful because your work enables utilities to manage EV loads effectively, preventing grid strain while supporting widespread EV adoption.

💡 A Day in the Life

A typical day involves collaborating with the team on enhancing backend services for the EV platform, optimizing data ingestion pipelines for vehicle telemetry, and developing features for both internal tools and customer-facing web applications. You might spend the morning debugging a data normalization issue in the ingestion service, then work on a new API endpoint for third-party partners, followed by code reviews and planning sessions for scaling vehicle communication systems.
