🏢 About Renew Home

Renew Home is building the world's largest sustainable virtual power plant by aggregating smart home devices. This mission-driven startup offers the chance to directly combat climate change through innovative software, working remotely with a team passionate about decarbonizing the grid.

About This Role

As a Staff Engineer, you'll architect and build full-stack features that connect millions of smart home devices to the grid, enabling real-time energy optimization. You'll lead technical design decisions, mentor engineers, and collaborate across teams to deliver a seamless user experience that directly impacts renewable energy adoption.

💡 A Day in the Life

Start with a stand-up to align with your team on feature progress and blockers. Spend the morning coding a new backend API for device data ingestion and a React component for user dashboards. After lunch, review a junior engineer's PR, then join a cross-team design review for a demand response feature. End the day by analyzing database query performance and planning the next sprint's architecture.
