Software engineer (backend / cloud / mobile app)

360 Watts: an energy-tech startup
We are developing an Energy Management mobile-first B2 C app that connects solar generation, battery storage, and smart-home appliances into a unified interface — empowering users to monitor, optimise, and automate their energy usage at homes.

Our product vision spans from AI-integrated control (phase 1) and will transition to AI-native agents (phase 2).
Roles & Responsibilities
We are hiring an experienced Software Lead who will own the overall system architecture, backend development, and cloud infrastructure of our EMS platform.

You’ll work closely with our Io T, ML, solar, and UI/UX team to bring the product to market.
This is a high-ownership, builder-first role with strong potential to grow into AI-Software Lead .

Design the end-to-end software architecture for the EMS backend, mobile app services, and data infrastructure
Define modular components for device integration, data pipelines, ML inference, and real-time user interfaces
Ensure scalability, security, and maintainability across backend and API layers
Own architectural decisions as the product evolves from AI-integrated to AI-native agentic application
2) Backend development + Cloud:
Design, implement and maintain cloud-based backend systems using Python (Fast API) or Node.js (Nest JS preferred)
Build modular, secure REST APIs for real-time data ingestion, device control, alerts, and AI model integration
