Mobile app Software Engineer (Architecture + Backend/Frontend)

>> 360Watts: an energy-tech startup

You will lead the development of an Energy Management mobile-first B2C 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. The product vision spans from AI-integrated control (phase 1) and will transition to AI-native agents (phase 2).

>> Roles & Responsibilities

We look for an experienced Software Lead who will own the overall mobile app/system architecture, backend development, data and cloud infrastructure of the product. You’ll work closely with our IoT, ML and solar engineers, as well as an UI/UX designer to bring the final product to market.

This is a high-ownership, builder-first role with strong potential to grow into AI-Software Lead.

1) System architecture

• Design the software architecture of the EMS backend, data & cloud infrastructure, and API ecosystem
• Define modular components for IoT device sync, ML model inference, mobile interfaces, and control logic
• 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 (FastAPI) or Node.js (NestJS preferred)
• Build modular, secure REST APIs for real-time data ingestion, device control, alerts, and AI model integration
• Design time-series data schema and store telemetry data using PostgreSQL/TimescaleDB
• Deploy containerised services (Docker) and CI/CD pipelines to AWS or GCP
• Handle role-based access, API observability, logs, uptime metrics, and system scaling

2) Additional:

• Build or contribute to React Native mobile app (ideal if you have mobile frontend experience)
• Help develop web-based internal tools or dashboards (React/Next.js)

>> Experience & Skillsets required

• 2–3 years experience in full-stack or backend software development
• At least 1 production-ready product or 2-3 MVP delivered to end users — SaaS or mobile app
• Prior lead or support role in system design or architecture for a SaaS/mobile/IoT product
• Experience in backend development with Python (FastAPI) or Node.js/NestJS
• Experience designing and managing PostgreSQL databases with telemetry or analytics data
• Experience with API versioning, CI/CD, Docker, and cloud deployment (AWS/GCP)
• Exposure to ML model integration (serving endpoints, forecasting APIs, etc.)
• Experience working in small, fast-moving teams (startup or lean product development teams)

>> Job details

• Location: Coimbatore (100% On-site)
• Start Date: 01.12.2025 or later
• Compensation: Negotiable based on experience & skillsets
